dark in color. Interior surfaces of an oven become hot

enough to cause burns. During and after use, do not

touch, or let clothing or other ﬂammable materials

contact heating elements or interior surfaces of oven

until they have had suﬃcient time to cool.

Power Connections

• DO NOT cook items wrapped in cling wrap or

plastic ﬁlm.

• DO NOT overcook food. Carefully attend to the

oven if paper, plastic, or other combustible materials

are placed inside the oven to facilitate cooking.

To avoid potential hazards, only the manufacturer, its

service agent, or a similarly-qualiﬁed person should

replace a damaged power cable. Flexible conduit,

conductors and connectors are supplied by the manu-

facturer. e oven must be connected using the ﬂexible

conduit and conductors provided.

• Listen for fan – a fan noise should be heard some-

time during the cleaning cycle. If not, call Customer

Service (866.447.3783) before self-cleaning again.

• DO NOT clean the door gasket. e door gasket is

essential for a good seal. Care should be taken not to

rub, damage or move the gasket.

• DO NOT use oven cleaners. No commercial cleaner

or oven liner protective coating of any kind should

be used in or around any part of the oven. Residue

from oven cleaners will damage the inside of the

oven when the self-clean mode is used.

• If the oven is malfunctioning in the self-clean mode,

turn oﬀ or disconnect the appliance from the power

supply and have it serviced by a qualiﬁed technician.

• Complete instructions on the operation of the

self-clean mode can be found on pages 2.10 and 3.4.

serviced before activating the magnetron or other

microwave source, and make repairs as necessary:

(1) interlock operation, (2) proper door closing,

(3) seal and sealing surfaces (arcing, wear, and other

damage), (4) damage to or loosening of hinges and

latches, (5) evidence of dropping or abuse.

c) Before turning on microwave power for any service

test or inspection within the microwave generating

compartments, check the magnetron, wave guide or

transmission line, and cavity for proper alignment,

integrity, and connections.

d) Any defective or misadjusted components in the

interlock, monitor, door seal, and microwave

generation and transmission systems shall be

repaired, replaced, or adjusted by procedures

described in this manual before the oven is released

to the owner.

e) A microwave leakage check to verify compliance with

the Federal performance standard should be per-

formed on each oven prior to release to the owner.

1.1

Theory of Operation

Certiﬁcations

e TurboChef Residential Speedcook oven

cETLus

combines high-speed forced air impingement and

microwave energy to cook food up to 15 times faster

than a conventional oven. e re-circulating air

transfers heat to the food and then passes through

a catalytic converter where excess grease and odors

are removed and combusted. Simultaneously, precise

bursts of microwave energy cook the food from the

inside out. is combination of heating technologies

quickly cooks food and seals moisture to help ensure

chef-quality results in a fraction of the time.

Electrical Speciﬁcations

Phase: Single

Frequency: 60 Hz

Current: 50 amp (DWO) / 30 amp (SWO)

Cord: 4-wire (inc. ground)

Voltage: 208 or 240 (depending on model)

Connection: 5½ ft ﬂex conduit

Total Connected Power: 50 amp (DWO) / 30 amp

is manual includes instructions for servicing,

troubleshooting, installing, cleaning, and operating

the TurboChef Residential double and single wall

ovens. If you have questions not addressed in this

manual, contact Technical Service (866.447.3783,

+1 214-379-6000) or your Authorized Distributor.

NOTE: Unit includes a 5½-ft ﬂex conduit to be

used between the oven and conduit box. Connectors

are supplied by the installation electrician.

Catalytic Converter

e catalytic converter removes odors and grease

from the air inside the cook cavity. It is also

responsible for limiting and removing any smoke

from the cavity in case of a spill. Do not use oven

cleaner when cleaning the Speedcook oven, as the

catalyst can become damaged by the use of caustic

cleaners, resulting in a non-warranty service call.

See pages 2.10, and 3.4 for approved self-cleaning

instructions.

NOTE: Branch circuit MUST be protected with a

50-amp (Double Wall Oven) or 30-amp (Single Wall

Oven) over-current protector.

CAUTION: If there is a high leg in supply

voltage, ensure it is not on L2. Having it present on

L2 will damage critical 120V oven components.

Installation Safety Instructions

Read all installation instructions thoroughly before

installing.

Installation

Cabinets should be cut according to dimensions on

pages 1.4 and 1.5. Failure to adhere to the Rough

Wall Opening speciﬁcations may cause corners of

the cabinet opening to be exposed. If the oven is

being installed near a wall or door, there should be at

least .25 in (6.35 mm) space between the wall/door

and the sides of the oven trim.

CAUTION: DO NOT lift the oven by the

door handle(s). Doing so will require a door-leakage

test to be performed (see page 5.4), and could cause

the door(s) to come oﬀ or misalign, requiring repair

and/or replacement.

TurboChef recommends using standard 2x4 wood

support posts with a minimum of .5 in (12.7 mm)

solid base to support the oven. Support posts should

be level with the ﬂoor line and well secured to the

base of the cabinet. Base cabinet support must be

able to support the oven’s weight – 410 lbs (186

kg) DWO and 230 lbs (105 kg) SWO. TurboChef

strongly recommends a solid base as shown in the

illustrations on the following page.

CAUTION: e Double Wall Oven weighs 410

lbs (186 kg), and the Single Wall Oven weighs 230

lbs (105 kg). Two or more individuals are required to

lift either oven.

CAUTION: DO NOT remove bottom wood

support rails until the oven is lifted into the cabinet.

ƒ Due to the oven’s weight, it is sometimes

necessary for installers to utilize special handling

equipment, such as hand trucks, dollies, etc. Use

of such equipment can damage the kitchen ﬂoor

surfaces. TurboChef recommends that all exposed

ﬂoor surfaces be protected by applying laminate

or plywood sheets, along with protective moving

blankets before using such equipment. Failure to

do so may result in scarring and damaging the

homeowner’s ﬂoors.

ƒ Installation, electrical connections, circuit

breakers, and grounding must comply with local

codes.

ƒ Ensure power is disconnected at the breaker

throughout the installation process.

ƒ is oven contains breakable components – use

extreme caution when lifting and placing it.

ƒ A minimum 1-inch clearance, to allow for proper

airﬂow, is required above the top control panel

area and below the base. Failure to maintain this

clearance may cause the oven to function

improperly.

ƒ DO NOT push on the outer frame. Doing so

could cause the door(s) to misalign, requiring

repair and/or replacement.

Due to the oven frame’s overall depth, adhere to the

power supply line location shown in Figures 1.2 and

1.3 on page 1.4 to obtain a proper ﬁt in the cabinet.

If necessary due to a low or high conduit box, a 2”

diameter hole should be drilled where indicated to

allow the power cord to reach the power source.

NOTE: DO NOT shorten conduit. Correct conduit

before installing oven into cabinet.

e oven utilizes ambient air from the kitchen to

assist in keeping the operational components cool.

is air is drawn in through the top control panel

area through openings in the top access panel and

exhausted through an opening at the base of the

oven. Please allow a 1-inch minimum clearance

above and below these areas.

Should you have any questions or concerns about

how the cabinets are built, please contact TurboChef

Customer Service 866.447.3783 before installing the

oven.

ƒ During installation, TurboChef recommends

removing the lower door prior to lifting the oven

from the front (Double Wall Model only.) DO

NOT remove the top door of the oven during

installation or at any other time. is door should

only be removed by an authorized service agent.

2.2 OVEN CONTROLS AND COOKING - THE SPEEDCOOK OVEN

In the TurboChef Speedcook Oven, the traditional

Cook Modes

explanation of baking remains the same. However,

the hot air is moved through the cook cavity at

higher speeds than in a traditional oven. is rapid

movement of air decreases cook times while ensuring

foods bake evenly and retain more moisture.

When in the Bake mode, keep in mind that metal

cookware will provide more bottom browning while

items in glass cookware will cook a little faster. Bake

pizzas on a pizza pan or place them directly on the

oven rack. Some casseroles may need to be covered

with parchment paper to prevent over-browning.

e Speedcook oven features seven modes that

enable the user to cook a wide variety of foods.

- Air-Crisp

- Bake

- Broil

- Dehydrate

- Favorites

- Roast

- Toast

To access Air-Crisp, Bake, Broil, Dehydrate,

Favorites, Roast, or Toast cook modes, turn the

CookWheel to the desired cook mode.

Broil

Broiling directly exposes food to radiant heat (as

over a ﬁre or on top of a grill). e heat is direct and

intense, and it diﬀers from baking or roasting in

that only one side of the food is exposed to the heat

source. Generally, broiled foods are quick cooking,

inherently tender, relatively lean, and not too thick.

NOTE: Unlike traditional ovens or the lower double

wall oven, Speedcook oven cooking parameters will

vary signiﬁcantly on a cook-by-cook basis. For

troubleshooting cooking problems, see section 6 in

this manual. For information on component

measurements and testing, see section 5.

e Broil mode on the TurboChef Speedcook Oven

will yield the same or superior results as broiling in

any traditional oven. e only real diﬀerence is that

your food cooks faster due to the hot air moving

through the cook cavity at increased speeds.

Cast iron grill pans, metal sheet pans, and metal

broiling pans all work well in this mode.

All Modes

Air-Crisp

Dehydrate

ink of Air-Crisp as air-frying. is mode is great

for foods that traditionally taste best when fried –

like french fries – as well as items containing any sort

of breading or stuﬃng that should toast and brown

in the cooking process – like stuﬀed mushrooms.

Considered the original form of preservation, dehy-

drating food removes the product’s natural moisture

by slowly drying it with a low heat. Manually, food

can be dehydrated by placing thin slices on racks

and allowing them to dry assisted only by sun or air.

To shorten the dehydrating process, the TurboChef

oven utilizes low temperature air moving at higher

speeds.

In this mode, high temperature air moves through

the cook cavity at varying speeds to brown and crisp

the food product. Food comes out with a nice

caramelization and is lower in fat content than if it

had been deep fried. Metal sheet pans work well in

this mode.

is mode is ideal for products like banana chips

and other dried fruits, as well as dried meats, like

beef jerky. Sheet pans, TurboChef teﬂon screens, and

pizza pans (with or without holes) are all recom-

mended for use with this mode.

Bake

Traditionally, baking is cooking with dry heat. Hot

air from the top and bottom of the oven envelopes

the food in a radiant dry heat, perhaps with a little

moisture from the food, which circulates as a vapor

in the oven.

Favorites

e Favorites mode is a tool that allows the user to

store and easily recall up to 9,999 cook settings for

the user’s favorite recipes. is mode truly allows you

to cook any recipe quickly and easily – regardless of

whether it is a perfect match to one of the pre-

programmed settings or not. In addition to any set-

tings that the user saves, the settings for the last ten

cooks are always saved in this mode. e Favorites

mode gives the user access to Convection Bake, De-

frost, and Microwave functions. To learn more about

the Favorites mode, see below.

NOTE: Convection bake, defrost, and microwave

cook cycles cannot be saved to Favorites and will not

appear in “View Last Cooked (10).”

is section contains information about the

following:

- Cooking a Recently Prepared Dish

- Cooking a “Favorite” Dish

- Using the Convection Bake Mode

- Using the Defrost Mode

Roast

- Using the Microwave Mode

Traditionally, roasting implies cooking food with an

open ﬂame, as on a spit in front of a ﬁre.

NOTE: If the oven does not contain some of these

options, verify it has received the most recent soft-

ware upgrade. See page 4.3 for details.

Roasting and baking in an oven are essentially the

same thing, but roasting is mostly used for meats

and vegetables. In the top oven, a combination of

low and high speed air is used to brown the outside

of food while retaining moisture inside.

NOTE: If for some reason the SD card must be

replaced, you must back up your Favorites to retain

them. See page 4.3 for more details.

Roasting pans (without lids), glass casserole dishes

(with or without lids), and sheet pans all work well

with this mode. Shallow pans will allow food to

brown more. An uncovered pan without liquids will

help keep the heat dry and allow foods to brown and

crisp. Setting meats and poultry directly on a rack in

a pan keeps them from steaming in their own juices.

Cooking a Recently Prepared Dish

e Speedcook oven automatically saves a record of

the user’s last 10 cooks, including any adjustments

made to the selected preprogrammed setting, giving

the user quick access to their most recently-used

cook settings.

Toast

To cook a recently-prepared dish,

1. Turn the CookWheel to “Favorites.”

2. Select “View Last Cooked (10).”

3. Select the dish to be cooked.

4. Select “Cook” and press start or the inner

CookWheel knob.

Toasting browns and crisps foods like bread, bagels,

and tortillas. Using high heat and high speed air, the

Toast Mode can enhance ﬂavor and melt cheese.

For best results, place food directly on the oven rack.

For products that may run over, like ﬁlled pastries,

use a metal sheet pan.

5. Follow the Basic Cooking steps (page 2.5),

beginning with mode 3.

Favorites Cooking

Cooking a ”Favorite”Dish

e Favorites mode allows the user to store and

quickly access the cook settings for their favorite

recipes and food items and gives them access to the

convection bake, defrost, and microwave modes

(for information on how to access convection bake,

defrost, and microwave functions, see page 2.4).

e Favorites mode allows the user to store and

quickly access the cook settings for your favorite

recipes and food items. To save a dish to Favorites,

see page 2.9.

To cook a “Favorite” dish,

1. Turn the CookWheel to “Favorites.”

2. Select the dish to be cooked.

3. Select “Cook” and press start or the inner

CookWheel knob.

Cooking in the Favorites mode generally follows the

Basic Cooking process on page 2.5; however, users

must choose between cooking a recently prepared

dish, cooking a “Favorites” dish, or using the

convection bake, defrost, or microwave functions.

3.2 OVEN CONTROLS AND COOKING - THE BOTTOM OVEN

Convection Bake

Cook Modes

Convection Bake uses the same heating elements

as Bake with the addition of a convection fan and

heater in the back of the cook cavity. is fan and

heater help heat and circulate the air evenly

throughout the chamber to produce superior

browning and crisping.

e bottom oven (double wall only) is both a

conventional and convection oven that provides

uniform cooking throughout. e bottom oven

features ﬁve cook modes.

- Bake

- Broil

- Convection Bake

Any food cooked under the Bake mode can also

be prepared using Convection Bake and vice versa.

Items cooked under Convection Bake will cook

about 33% faster than when cooked under Bake.

- Convection Roast

- Roast

e table below details heater element activity

within each mode.

Convection Bake

Convection Roast

Roast

Any item cooked under Roast can be prepared using

Convection Roast and vice versa. e one diﬀerence

is that Convection Roast uses additional heating

elements, causing it to cook about 33% faster.

Bake

Traditionally, baking is to cook with dry heat. Hot

air from the top and bottom of the oven envelopes

the food in a radiant dry heat, perhaps with a little

moisture from the food, which circulates as a vapor

in the oven.

Roast

Roasting in an oven is essentially the same as baking,

but roasting is used mostly for meats and vegetables.

Hot air from the top and bottom of the oven is used

to brown the outside of food while retaining

moisture inside.

In the bottom oven of the double wall oven, unlike

most traditional ovens, the bottom heating element

is concealed beneath the cook cavity. is feature

allows for a bigger cook cavity, easier cleaning, and

more uniform heating.

In the bottom oven of the Double Wall model, the

two top heating elements provide better control and

optimized broiling and roasting.

Broil

Warm Setting

e warm setting uses heat from the top and bottom

of the oven to keep the cook cavity at 145°F (63°C),

the perfect holding temperature for food.

Broiling directly exposes food to radiant heat (as

over a ﬁre or on top of a grill). e heat is direct and

intense, and it diﬀers from baking or roasting in that

only the top side of the food is exposed to the heat

source.

Proof Setting

Generally, you broil foods that are quick cooking,

inherently tender, relatively lean, and not too thick.

e Proof setting uses heat from the top and bot-

tom of the oven to keep the cook cavity at 90-105°F

(32-41°C), the perfect temperature for yeast dough

to rise. Some doughs may require moisture to proof

correctly. If moisture is needed, place a sheet pan of

water under the lower rack.

Heater Assembly

Convection System -

Speedcook Oven

e Speedcook oven convection system is designed

to rapidly heat, clean, and recirculate air into the

cook cavity. is section contains information about

the following components:

e Speedcook oven heater assembly consists of

three elements. e elements are voltage speciﬁc and

cannot operate properly without the correct

voltage applied. Conﬁrm incoming voltage matches

the oven’s speciﬁcations. During preheat, all three

elements are energized.

- Blower motor (bottom)

- Blower motor (top)

- Blower motor controller (BMSC)

- Heater assembly

- Jetplate (bottom)

- Jetplate (top)

- Stirrer motor and assembly

e K1 solid state relay (see page 5.12) controls L1

voltage to the two primary elements while the K8

relay (see page 5.10) controls L1 voltage to the

preheat element. e K9 relay (see page 5.11)

controls L2 voltage to all three elements.

NOTE: For 208 volt units, preheat amperage is

at 30.8 amps and once the temperature has been

reached, the operating amperage is at 20.5 amps.

For information on accessing and removing parts,

and for part numbers, see the Appendix.

NOTE: For 240 volt units, preheat amperage is

at 28.8 amps and once the temperature has been

reached, the operating amperage is at 19.2 amps.

Blower Motor (Bottom)

e bottom blower motor runs on varied 3-phase

power to force the air into the upper oven cavity.

e motor is controlled by a proprietary controller.

Jetplate (Bottom)

e bottom blower motor can be tested in installer

setup mode (see page 4.4).

e bottom jetplate channels air that is generated

from the bottom blower motor.

Blower Motor (Top)

Jetplate (Top)

e top blower motor runs on varied 3-phase power

to force the air into the upper oven cavity. e

motor is controlled by a proprietary controller.

e top jetplate channels air that is generated from

the top blower motor. is air passes through a

stirrer before entering the cook cavity through the

jetplate holes.

e top blower motor can be tested in installer

setup mode (see page 4.4).

CAUTION: e top jetplate is ceramic and

may crack or break if mishandled. Be careful when

removing or reinstalling it.

Blower Motor Controller (BMSC)

e blower motor controller is proprietary and will

only operate the convection motors described above.

e motor controller is controlled on command

from the control board and a 0-10VDC speed

command from the control board.

Stirrer Motor and Assembly

e stirrer is responsible for evenly distributing hot

air and microwaves that are launched from the top

of the oven into the cook cavity. e stirrer is driven

by a motor that remains on during a cook cycle.

When the oven is cooling down, the stirrer motor

turns oﬀ when the cook cavity temperature recedes

below 160°F (71°C).

e blower motor controller can be tested in

installer setup mode by testing the blower motors

(see page 4.4). For additional troubleshooting, see

page 6.3.

To visually test stirrer motor operation, go to Bake,

which will automatically turn on the stirrer, the stir-

rer is visible through the upper jetplate holes.

Wheel must not be in the Oﬀ position.

e right lock motor assembly consists of a motor,

locking mechanism for the right side of the Speed-

cook oven door, and three switches that activate

when a cam is turned while the door closes.

2. Place a water load into the cook cavity (Figure

5.3). Water load must conform to the following

speciﬁcations:

For Gen 1 ovens, when the secondary, monitor, and

lock switches are closed, the I/O control board opens

the K2 relay to prevent a direct short to the 20-amp

fuse.

10. Close the door.

Doubler Circuit, Voltage

e microwave system consists of a magnetron and

voltage doubler circuit. e voltage doubler circuit

consists of a special step-up transformer, a capacitor,

and a diode. Two separate transformers are

incorporated; one is the 1-10 step-up, multiplying

the incoming voltage by 10, the other is the

ﬁlament transformer that supplies approximately

3.5 VAC to the magnetron ﬁlaments to warm them

before the 4000+ volts are applied. is function

extends the life of the components. e oven uses

two magnetrons, each magnetron circuit is separate

and independent.

11. Ensure the door opens and closes freely.

12. Push the oven back into its original position.

Halogen Bulb Replacement

CAUTION: DO NOT touch the bulb with

bare ﬁngers; rather, use gloves, cloth, or tissue

when handling the bulb. If the bulb is accidentally

touched, clean it with isopropyl alcohol before

applying power.

CAUTION: To avoid burns, ensure the oven

cavity has had adequate time to cool before

performing the below procedure.

High-Voltage Capacitors

e high-voltage capacitor works in combination

with the diode to eﬀectively double the already-high

voltage from the secondary (output) winding of the

transformer. e capacitor is used to store the power

during the positive to negative swing of the

incoming AC voltage. When the oven is connected

to power, the capacitor will still have 2000+ volts

setting on the terminals. During magnetron

operation, the potential is 4000+ volts.

To replace a bulb in the lower oven (use RWD-

3016),

1. Gently pry the halogen light cover from the

oven cavity wall using a ﬂat-surfaced object. Be

careful to not damage the porcelain coating on

the oven cavity wall.

2. Remove the bulb by gently pulling it out of the

socket.

3. Install the new bulb.

High-Voltage Diode

Reinstall the cover, ensuring that it snaps into

place.

e high-voltage diode works in combination with

the high-voltage capacitor to eﬀectively double the

2000+ volts output voltage from the high-voltage

transformer. During magnetron operation, the

potential is 4000+ volts. is high voltage allows the

magnetron to produce the microwave energy.

Microwave System

is section contains information about the

following components:

e high-voltage diode is assembled by connecting

several 1000-1500 volt semiconductor diodes in a

series to increase the reverse voltage capability. In the

circuit, the high-voltage diode conducts to prevent

the ﬁlament voltage from becoming positive, thus as

the high-voltage winding of the transformer goes to

2400, the high-voltage capacitor is charged to 2000+

volts.

- Magnetrons

- Stirrer motor and assembly

- Waveguides

For information on accessing and removing parts,

see the Appendix.

5.7

When the high-voltage winding starts to go

toward negative, the high-voltage diode becomes

non-conducting with the charged high voltage

capacitor in series with the high-voltage winding.

When the transformer gets to its negative peak of

-2400, the voltage applied to the ﬁlament is negative

4000+ volts.

Magnetrons

e magnetron generates microwave energy by

means of 4000+ volts supplied by the microwave

circuit. Due to the very high voltage present during

operation, the only safe way to test this component

is by a resistance test of its ﬁlament with the power

disconnected and the capacitors properly discharged.

e magnetron can have a good ﬁlament and still

not operate properly. All of the testing should be

completed on the other microwave components ﬁrst

before checking the magnetron. If all tests listed

in this manual are completed for the transformer,

diode, and capacitor, and all show to be within

speciﬁcations, the magnetron will be the defective

component.

High-Voltage Transformers

e high-voltage transformers are ferro-resonant,

limiting fault currents and minimizing magnetron

power changes due to input voltage changes. e

high-voltage transformer supplies the high voltage

for the Voltage Doubler Circuit. For Gen 1 ovens,

they are controlled via the K3 and K4 relays. For

Gen 2 ovens, they are controlled by relays 2 and 3

on the relay board (outputs RBJ5 and RBJ4).

CAUTION: Be careful to not allow debris

into the waveguides when servicing the magnetrons.

Wiring a High-Voltage Transformer

Stirrer Motor and Assembly

DANGER: Never attempt to wire or measure

the secondary voltage values of the high-voltage

transformers with the high-voltage transformers

enabled. Lethal voltage will be present.

e stirrer is responsible for evenly distributing hot

air and microwaves that are launched from the top

of the oven into the cook cavity. e stirrer is driven

by a motor that remains on during a cook cycle.

When the oven is cooling down, the stirrer motor

turns oﬀ when the cook cavity temperature recedes

below 160°F (71°C).

e proper re-installation of a high-voltage

transformer is critical. Upon removing a high-voltage

transformer, make sure to note where each wire was

connected. Refer to the oven schematic (Section 7)

detailing the proper wiring.

To visually test stirrer motor operation, go to Bake,

which will automatically turn on the stirrer, the stir-

rer is visible through the upper jetplate holes.

As shown in the schematic, transformers are installed

mirror opposite and wired 180° out-of-phase. It is

essential for longevity that the high-voltage

transformers remain 180° out-of-phase. is can

be checked by placing a volt meter across terminals

T1-1 and T2-1 (primary voltage). If the meter reads

0 VAC, the high-voltage transformers are most likely

wired in-phase.

Waveguides

e waveguides channel microwaves into the cook

cavity. To prevent the life of the magnetrons from

being shortened, be careful to not allow debris to

enter into the waveguides when servicing the

magnetrons.

As a last check, energize the microwave system and

verify the voltages between the incoming voltage

taps on each high-voltage transformer. Taps 1 and

2 = 208V. Taps 1 and 3 = 240V. Wiring issues must

be corrected prior to returning the oven to service.

Voltage at the wall must match the transformer

conﬁguration.

open (N.O.) switch and the upper and lower cooling

fans are activated. Also, the three upper oven heating

elements receive L2 voltage and the stirrer mo-

tor activates. In any position other than “Oﬀ” and

“Favorites” the control board also closes the relays

that supply L1 voltage to the three heating elements

in the upper oven, preheating the oven during the

sees an open door condition. e bottom fuse is

rated 15 amps. It is wired in the circuit to protect

the low voltage components in the oven.

Gen 1 ovens also contain a 5-amp fuse located on

the right magnetron cover. is fuse is powered

by the K9 relay to provide power to the upper and

lower cooling fans.

Display, Speedcook Oven

e upper liquid crystal display is the primary user

interface for the Speedcook oven. It is connected to

the control board via a ribbon cable. To ensure that

the cable is properly positioned, a red line is located

on only one side of the cable. is red line should

face downward on the upper display assembly. It

should also point left on the control board. Failure

to reattach the ribbon cable correctly could lead to a

direct short in the control board and upper display

assembly.

For Gen 2 ovens, the fuses are located on the relay

board. Fuse 1 (right side) is rated to 20 amps, and

fuse 2 (left side) is rated to 15 amps (Gen 2 ovens do

not contain a 5 amp fuse).

High Limit Thermostats

e high limit thermostat is a 250 VAC, 3-pole,

manual-reset thermostat with a trip point of 572°F

(300°C). e thermostat interrupts power to the

main convection heater in the event of an abnormal

condition.

NOTE: In Gen 1 ovens, the upper display ribbon

cable is a ground source for the control board to the

oven frame.

Pertaining to the double wall oven, the upper and

lower ovens have independent high limit thermostats

located in their respective upper and lower electrical

compartments. Reset the high-limit thermostat by

pressing the reset button.

Electrical Compartment Cooling Fans

Both the upper and lower electrical compartment

cooling fans are activated when either the Cook-

Wheel (top oven) or the selector switch (bottom

oven) are turned to any selection other than oﬀ.

Both fans are independently monitored by motion

sensors that will display an error message on the

display if either fan fails to function normally. It

accomplishes this by sending 5 VDC pulses to the

control board while the fan is spinning; these pulses

occur so fast that a voltmeter will register an average

reading of 2.5 VDC when the fan is spinning and

a constant 5 VDC or 0 VDC when the fan is not

spinning.

Latch Mechanism (Lower Oven)

e latch mechanism automatically locks the lower

oven door during the self-clean cycle to prevent

exposure to the extreme temperatures used to clean

the inside of the oven. e oven door can also be

locked by pressing the door lock button underneath

the lower display. It will not unlock unless the oven

temperature is below 500°F (260°C).

5.10 OVEN SYSTEMS

Magnetron Cooling Fan

Relay - K2 Monitor (Gen 1 Oven)

e magnetron cooling fans supply air to the

magnetrons. For Gen 1 ovens, they are actuated by

the K5 relay. For Gen 2 ovens, they are actuated by

relay 4 on the relay board (RBJ19-1). At the end of a

microwave cook cycle, the cooling fans will continue

to operate for an additional 2 minutes (on older ver-

sions of the control software, the magnetron cooling

fans run for an additional 5 minutes).

e K2 relay is a 30 amp, double-pole, double-

throw, class F, 24 VDC relay coil. It is used in the

magnetron circuit along with the K3 and K4 relays.

If the door is opened during a cook cycle, and the

K3 or K4 relays are still closed due to a door switch

failure, this relay will cause L1 and L2 voltage to

short circuit and blow the 20-amp fuse. e system

is designed to protect the user in the case of a

door switch failure. e K2 relay coil is supplied

with 24 VDC power except when the door is open

or oven power is disconnected.

Magnetron Thermostats

e magnetron thermostats are wired in-series with

the input voltage of the HV transformers. ey open

at 280°F (138°C).

Relay - K3 T1 HV Transformer (Gen 1 Oven)

e K3 relay is a 30 amp, double-pole, double-

throw, class F, 24 VDC relay coil. is relay sends L1

voltage to the T1 transformer.

Power Supply, 12 VDC

e 12 VDC power supply supplies power to the

halogen oven lights.

Relay - K4 T2 HV Transformer (Gen 1 Oven)

e K4 relay is a 30 amp, double-pole, double-

throw, class F, 24 VDC relay coil. is relay sends L1

voltage to the T2 transformer.

Power Supply, 24 VDC

e 24VDC power supply supplies voltage to the

control board (and relay board for Gen 2 ovens).

Relay - K5 Mag Cooling Fan (Gen 1 Oven)

Relay Board (Gen 2 Only)

e K5 relay is a 30 amp, double-pole, double-

throw, class F, 24 VDC relay coil. is relay activates

the magnetron cooling fan during and after

magnetron operation.

Gen 2 ovens contain a relay board consisting of the

fuses (page 5.9), clock transformer, and all relays

described below. If any of these components fail,

except the fuses, the entire relay board must be

replaced. See page 7.7 for a schematic with test point

locations.

Relay - K6 Right Side Door Lock (Gen 1 Oven)

e K6 relay is a 30 amp, double-pole, double-

throw, class F, 24 VDC relay coil. is relay controls

the right side door lock motor.

- Relay 1: Monitor

- Relays 2 and 3: HV transformers

- Relay 4: Magnetron cooling fan

- Relay 5: Door lock, upper left

- Relay 6: Door lock, upper right

- Relay 7: Cooling fan, upper

Relay - K7 Left Side Door Lock (Gen 1 Oven)

e K7 relay is a 30 amp, double-pole, double-

throw, class F, 24 VDC relay coil. is relay controls

the left side door lock motor.

- Relay 8: Stirrer motor

- Relay 11: Cooling fan, lower

- Relay 12: Convection fan

Relay - K8 Preheat (Gen 1 Oven)

- Relay 13: Door light, lower

e K8 relay is a 30 amp, double-pole, double-

throw, class F, 24 VDC relay coil. e K8 relay

controls the L1 voltage to the Speedcook oven’s

preheat element. When the CookWheel is turned to

begin the selection process, the control board sends

- Relay 14: Pre-heater

5.11

24 VDC to the activating terminals of the relay. e

N.O. switch closes to send L1 voltage to the preheat

element. When the RTD registers that the oven has

reached 80% of the preset temperature, the control

board stops sending 24 VDC to the K8 relay and the

switch opens to turn oﬀ the preheat element.

SD Card

e SD card, which is inserted into the control

board, stores the control software for the oven.

CAUTION: When inserting an SD card,

always ensure it is set to unlocked; otherwise the

oven will not properly save settings. DO NOT

remove the card when the oven is powered up.

Relay - K9 L2 Speedcook Heating Elements

e K9 relay is a 120 VAC single-pole, double-

throw, relay. is relay supplies L2 voltage to the

three Speedcook oven heating elements. On Gen 1

ovens, this relay also supplies L2 voltage to the upper

and lower cooling fans inline with the 5-amp fuse.

Before replacing the SD card, back up Favorites to a

USB drive (page 4.3)

After replacing the SD card,

1. Restore Favorites from the USB drive (page 4.3).

2. Set the Oven Conﬁguration to single or double

(page 4.4).

Relay - K10 Lower Door Lock (Gen 1 Oven)

e K10 relay works in conjunction with the lower

oven’s plunger light switch to activate the lower oven

lock motor. Terminal 2 on the selector switch

constantly supplies 120 VAC to the K10 relay’s

common. e control board activates the K10 relay’s

N.O. switch to the lower oven lock motor by using a

circuit inline with the plunger light switch.

Selector Switches

When the CookWheel or the lower oven selector

switch is turned to a setting other than oﬀ, the

switch between terminals 1 and 2 is closed. is

supplies L2 voltage to the lower cooling motor, the

activating terminal on the K13 lower heating

element relay, and the CookWheel to supply power

to the upper cooling motor. In other words,

whenever an oven is turned on, the electrical

compartment cooling fans also turn on. In Gen 1

ovens, the fans will turn oﬀ when the oven is turned

oﬀ. In Gen 2 ovens, the cooling fans will remain on

for an additional two minutes after the oven has

been turned oﬀ.

is means that the K10 relay will only activate the

lower oven lock motor when the oven door is closed

(plunger pressed).

Relay - K13 L2 Lower Heating Elements

(Double Wall Oven Only)

e K13 relay is a 120 VAC single-pole, double-

throw, relay. is relay supplies L2 voltage to the

four lower oven heating elements.

NOTE: e electrical cooling fans will also turn on

at any time regardless of the selector switch position

if the temperature within the upper electrical

compartment exceeds 140°F (60°C), or if the

temperature within the lower electrical compartment

exceeds 160°F (71°C).

RJ Cables

e RJ cables connect the control board to the

CookWheel and lower oven Mode and Temperature

switches.

In double wall ovens, the K13 N.O. closes and sup-

plies L2 voltage to the bake, convection, inner broil,

and outer broil elements. When a convection cycle is

selected, the convection fan is also powered and will

remain on until the convection cycle is no longer

selected.

RTD

e RTD uses resistance to register cook cavity

temperature. As heat increases in the oven, so does

the resistance registered in the RTD. is allows the

control board to accurately monitor the temperature

in the oven and activate/deactivate the elements as

needed. Refer to the ohms/temperature chart for

testing (page 6.5).

5.12 OVEN SYSTEMS

Solid State Relay - K1 L1 Speedcook

Thermostat, Cook Cavity

Heating Elements

To prevent temperature from running away during

normal oven operation, each oven is monitored by

a thermostat (270°F switch for Speedcook cavity

and 280°F for the lower oven cavity in double wall

ovens). In both the single and double wall oven, the

switch(es) are wired to the control board through

P7-18 and P8-6 (Gen 1) or pins J15-18 and J15-19

(Gen 2).

e K1 solid state relay is a 240 VAC, dual 40 amp

relay. is relay supplies L1 voltage to the Speedcook

oven’s heating elements. e control board sends

24 VDC to the K1 solid state relay to “open” and

“close” both sides of the solid state relay, which helps

ensure absolute temperature control.

Solid State Relay - K11 Bake and Convection

Elements (Double Wall Oven Only)

e K11 solid state relay is a 240 VAC, dual 40 amp

relay. is relay supplies L1 voltage to the lower

oven’s bake and convection elements (24 VDC

control voltage).

Thermostat, Cooling Fan Control

e cooling fan control thermostats are normally-

open snap switches that will close if the temperature

within the upper electrical compartment exceeds

140°F (60°C), or if the temperature within the lower

electrical compartment exceeds 160°F (71°C). ey

supply voltage from the terminal block to the upper

and lower cooling fans, allowing them to operate

if they are needed after the CookWheel or selector

switch has been turned to the oﬀ position. If either

thermostat closes, both cooling fans will be powered

on.

Solid State Relay - K12 Broil Elements: Inner

and Outer (Double Wall Oven Only)

e K12 solid state relay is a 240 VAC, dual 40

amp relay. is relay controls the L1 voltage to the

lower oven’s inner and outer broil elements. e

control board sends 24 VDC to the K12 SSR to

independently “open” and “close” each side of the

SSR, over 100 times per second, for absolute

temperature control.

USB Port

e USB port allows the oven operator to load

software updates from a USB drive. For instructions,

see page 4.3.

Speaker

e speaker provides audible feedback to the

operator whenever a key is pressed or a task (such

as a cook cycle) is completed, etc. See page 4.1 for

adjustments.

Connecting the USB Board (Gen 1 Oven)

e USB board connects to the control board via

a 10-pin molex cable (for USB board location, see

page A.7). Plug one end of the molex cable into the

control board’s P25 connector, as shown in Figure

5.4. Ensure that, when facing the oven, the cable’s

red stripe is on your right.

Temperature Switch (Lower Oven)

e temperature switch uses a six-wire (RJ) cable to

communicate the temperature selection to the

control board.

NOTE: e picture below shows the molex cable

not completely inserted, ensure you completely

insert the molex cable.

Transformer, Clock, 12 VAC

e 12 VAC transformer supplies voltage to the

Speedcook oven clock. For Gen 2 ovens, the 12 VAC

transformer is located on the relay board (terminals

RBJ18-1 and 2).

Plug the the other end of the molex cable into the

USB board as shown in Figure 5.5. Ensure that,

when facing the oven, the red stripe is on your left

and the two empty sockets are on your right.

CAUTION: e catalytic converter can be

cleaned with TurboChef oven cleaner and rinsed

thoroughly with distilled water. Let the catalytic

converter air dry before reinstalling. If TurboChef

oven cleaner is not available, DO NOT use a

substitute. Use distilled water only.

NOTE: e picture below shows the molex cable

not completely inserted, ensure you completely

insert the molex cable.

Exhaust Blower

e exhaust blower is located in the bottom rear of

the single wall oven. It’s purpose is to vent the hot

air from the electrical compartment.

Two Empty Sockets

Vent Catalyst

Red Stripe

In addition to the main catalytic converter, the

Speedcook oven contains an additional catalyst in

the vent tube path. is catalyst further assists in the

breakdown of grease and particulate matter before

the excess air enters the atmosphere.

Figure 5.5: USB Board, Connecting to Control Board

Wiring Harness

e wire harness distributes power to the oven’s

electrical components. See section 7 for schematics.

Exhaust System

is section contains information about the

following components:

- Catalytic converter

- Exhaust Blower

- Vent catalyst

Catalytic Converter

e catalyst functions by substantially lowering

the combustion temperature of grease entrained in

the air path to approximately the same temperature

of the airﬂow; thus the grease burns and breaks

down into CO₂and H₂O as it passes through the

catalytic converter. e catalyst will operate most

eﬃciently at temperatures above 475°F (246°C).

e catalyst material is very sensitive to certain

chemical compounds. Irreversible damage can occur

if the catalyst is exposed to cleaning chemicals

containing phosphates, NaOH, silicates, Na and

Potassium Salts. ese chemicals are found in most

commercial degreasers and cleaners; therefore, only

the self-clean feature should be used.

6.1

Oven Door Open (Gen 1)

Overview of Troubleshooting

When the door is closed, two cams are rotated by

the door’s actuators to close the left and right

interlock N.O. switches. ese switches are wired

in series between P7-5 and P8-5 on the control

board to monitor the door’s position. If this circuit

is broken during the preheat or cooking cycle, or if

the monitor switch, P7-15 and P8-4, fails, this error

screen is displayed.

is section contains information pertinent to

troubleshooting issues with the TurboChef

Residential Double Wall or Single Wall ovens.

It is divided into two main sections:

- Error Screens

- Component Testing and Troubleshooting

Within these sections, some procedures are relevant

only to speciﬁc oven models.

Possible causes:

- e door is open

e variables are:

- e door switch assemblies require adjustment

- Faulty left and/or right lock motor assembly

- e switch is not closing because the left and/

or right lock motor assembly has not been

installed correctly

- Double Wall Oven: If the procedure is speciﬁc

to a double-wall oven, it will be in regards to the

lower oven, as the top oven is functionally

identical to the single-wall oven.

- Single Wall Oven: No procedure will be speciﬁc

only to a single wall oven, as it is functionally

identical to the top oven of the double-wall.

- Gen 1: e procedure will apply only to ovens

with a serial number mask of TDO######.

Note that all single-wall ovens are Gen 2.

- Gen 2: e procedure will apply only to ovens

with a serial number mask of TDO2D######

or TSO2D######.

- Faulty wiring

- Faulty control board

- Failed monitor switch

Possible components to be replaced:

- Left lock motor assembly

- Right lock motor assembly

Troubleshooting:

1. Verify whether the door is fully closed.

- No designation: If there is no designation on a

procedure, then it applies to all oven types and

conﬁgurations.

2. Verify the hinges on the door have been fully

inserted (see page 5.2).

For more information on part descriptions and

functions, see Section 5: Oven Systems. For

information on removing parts, see the Appendix.

3. Test pins P8-4 and P7-15 for continuity through

6.2 TROUBLESHOOTING

With the door fully closed, loosen the door

Cooling Fan Failure (Gen 1)

switch’s adjustment screw(s).

A motion sensor on each of the two cooling fans sends

voltage pulses of 5 VDC to the control board. ese

pulses are created when a magnet on the

cooling fan oscillates around the sensor. If one of the

fans is not spinning for any reason, its magnet will not

oscillate and the fan’s motion sensor will not operate,

causing this error screen to be displayed.

With a screwdriver, adjust the switches at

the triangle adjustment slot.

When the door open message disappears,

move the slide an additional 1/32 in (.8

mm) and tighten the adjustment screw(s).

Open and close the door to ensure that the

open door message appears only when the

door is open.

Possible causes:

- Loose wire connection

- Faulty cooling motor

- Faulty motion sensor

- Faulty CookWheel mechanical switch

NOTE: If switches were adjusted or replaced, you

must perform a microwave leakage test (see page 5.4).

7. If adjusting the switches does not remove the

Door Open message, verify the switches are

operating correctly. If not, replace the faulty

switch(es). If they are, replace the control board.

Possible components to be replaced:

- Cooling motor assembly

See pages 6.7-6.9 for further troubleshooting.

Oven Door Open (Gen 2)

When the door is closed, the two cams in the switch

assemblies are rotated by the door actuators. ese

cams then actuate the door sensing switches. ese

switches are wired independently to the control

board; the left J15-7 and J15-8 and the right J15-9

and J15-10. If either switch is open, the error screen

is displayed.

Cooling Fan Failure (Gen 2)

e Gen 2 oven upper cooling fan is identical to the

one in the Gen 1 oven; however, the single wall oven

also includes a sail switch near the bottom exhaust fan

to check fan operation. If this switch fails to close, an

error will be displayed. All other causes are covered

in Gen 1 listing, above. See pages 6.7-6.9 for further

troubleshooting.

e monitor switch can also cause this error message;

check pins J15-6 and J15-5 for continuity. All other

causes are covered in the Gen 1 listing, above.

Temperature Control Failure

e control board monitors cook cavity temperature

with the use of one RTD in each oven. If the control

board loses communication with an RTD, this error

screen is displayed. See page 6.6 for the RTD testing

procedure.

Possible causes:

- Faulty wiring/loose connections

- Faulty upper or lower RTD

- Faulty control board.

Possible components to be replaced:

- RTD (upper or lower oven - both should

be tested)

- Control board

5. Turn the magnetrons oﬀ. Depending on the

Magnetron Failure

measurement, follow the below steps.

A current transformer located on the control board

monitors the current draw of the microwave system.

e oven uses two separate magnetron circuits, each

drawing approximately 8-9 amps. If the control board

senses 0 amps, this error screen is displayed.

If 15-19 amps are present, verify the magnetron

cooling fans are running whenever the magnetrons

are running. e thermostats can cause the

magnetrons to shut down and reset when cool.

Possible causes:

If 8.5-10 amps are present,

- Faulty K3 or K4 relay (Gen 1) or relay 2 or 3

(Gen 2; the entire relay board must be replaced)

- Faulty left or right high-voltage transformer

- Faulty left or right high-voltage capacitor

- Faulty left or right high-voltage diode

- Faulty left or right magnetron

- Faulty 20-amp fuse (Gen 2: located on relay

board as F1 fuse)

1. Check relay operation. For Gen 1, check the

control voltage from the control board at P8-13

+ P8-5, and at P8-14 + P8-5. For Gen 2,

visually check relays 2 and 3 for operation. If

they operate correctly, check the HV outputs to

each transformer at terminals RBJ-4 + RBJ-5.

2. Isolate the left and right magnetron circuits and

retest. For Gen 1 ovens, remove the brown lead

to the transformer. For Gen 2 ovens, remove

either RBJ-4 or RBJ-5.

- Faulty wiring

- Faulty control board

- Faulty left or right magnetron thermostat

If 0 amps are present,

Possible components to be replaced:

- K3 relay (Gen 1) or relay 2 or 3 (Gen 2; the

entire relay board must be replaced)

- K4 relay (Gen 1) or relay 2 or 3 (Gen 2; the

entire relay board must be replaced)

- High voltage transformer

1. Ensure power is reaching the oven from the wall.

2. Check the 20-amp fuse.

3. Check for incoming voltage at each transformer

when the magnetrons are energized. For Gen 1,

test voltage from the relays at the transformer.

For Gen 2, 208 or 240 VAC must be between

the blue wire at the CT coil (CT1-B) and either

terminal RBJ-5 (right) or RBJ-4 (left) on the

relay board.

- High voltage capacitor

- High-voltage diode

- Magnetron

- 20 amp fuse (Gen 2: located on relay

board as F1 fuse)

- Control board

- Left or right magnetron thermostat

Blower Failure

e control board sends voltage to the blower motor

speed controller (BMSC) to activate the blowers. If

both blowers successfully activate, a signal is sent back

to the control board to verify the system is

functioning normally. If that signal is not sent back to

the control board, this error screen is displayed.

Magnetron Failure Troubleshooting

1. Pull the oven 11” (280 mm) from the cabinet

and remove the top front cover.

2. Place the oven in Installer Setup mode (page 4.4).

3. Place a water load in the cook cavity.

Oven Over Temperature

To prevent temperature from running away during

normal oven operation, each oven cavity is monitored

by a thermostat (270°F [132°C] switch for Speedcook

cavity and 280°F [138°C] for the lower oven cavity in

double wall ovens). In both the single and double wall

oven, the switch(es) are wired to the control board

through P7-18 and P8-6 (Gen 1) or pins J15-18 and

J15-19 (Gen 2). If the ambient temperature near these

thermostats exceeds the temperatures given above, this

error screen is displayed. e thermostats are self reset-

ting; however, the oven is disabled until both switches

are closed.

2. Apply voltmeter probes to pins 1 and 5 on the

cooling fan motion sensor is faulty or a

motor assembly is not functioning and

needs to be tested.

Components that activate the cooling fans are:

- CookWheel (Speedcook oven)

- Mode knob (lower double wall oven)

- 140°F (60°C) snap switch (Speedcook oven)

- 160°F (71°C) snap switch (lower oven)

- Control board when the Speedcook cavity

temperature is above 350°F (177°C) and the

Cook-Wheel is in the oﬀ position.

6. If neither fan is operating, check the 5 amp fuse

located on the right magnetron cover in the top

oven electrical compartment. If the fuse has not

blown, Check the operation of the Cookwheel

and the K9 relay. If the fuse has blown, continue

7. Troubleshoot the following potential reasons as

to why the fuse was blown:

NOTE: If the CookWheel is set to “oﬀ,” the cooling

fans will stay on for an additional 2 minutes after

the cook cavity temperature recedes below 350°F

(177°C). If the CookWheel is set to any other mode,

the fans will remain on.

- Does the control board reset when the

CookWheel is in the oﬀ mode?

- Was/is there a supply power surge?

- Is the cooling fan faulty?

- Is any wiring faulty?

- Is the control board faulty?

NOTE: If the Speedcook cook cavity temperature

is above 350°F (177°C) or either snap switch has

closed, the cooling fans will remain on even if the

CookWheel is in the oﬀ mode.

8. Remove the 5-amp fuse, turn the Cookwheel to

oﬀ, and check the single side terminal of the

fuse block for 120 VAC.

the relay board at RBJ10 and RBJ11.

5. If the high limit switch is functioning

properly, apply one probe to any one of the

exposed female wire terminals and keep it there.

Apply the other probe to the three male

terminals on the high limit switch in sequence.

At least one of the three readings should register

240 VAC if the oven is heating (if this is the

case, go to Oven is Heating Up Very Slowly,

adjacent).

Testing for Control Voltage to the K1 SSR

DANGER: A high-voltage capacitor is located

near this relay. Contact with the high-voltage

capacitor could result in serious injury or death.

1. Turn the CookWheel to Bake to begin the

preheat cycle.

2. For Gen 1 ovens, apply the voltmeter

probes to P7-3 and P8-15, then to P7-3 and

P8-16 (on the control board). For Gen 2 ovens,

apply the voltmeter probes to RBJ22-7 and

RBJ22-1, RBJ22-7 and RBJ22-2 (on relay board).

e voltage reading for each should be 24 VDC.

If 24 VDC is present, the relay is receiving

voltage.

6. If none of the elements are receiving 240 VAC,

test the K9 relay, then the K1 and K8 relays

(Gen 1) or K1 and relay 14 on the relay board

(Gen 2) to verify both are receiving control

voltage from the control board.

Testing for Control Voltage to the K8 Relay (Gen 1)

verify the relay is receiving voltage from the blue

wires still attached to the relay in the upper-left

corner.

DANGER: A high-voltage capacitor is located

near this relay. Contact with the high-voltage

capacitor could result in serious injury or death.

4. If voltage is present, replace the relay and test

the oven. If no voltage is present, investigate for

broken wires.

1. Turn the CookWheel to Bake to begin the

preheat cycle.

both the K1 and K8 relays are stuck open.

Testing for a K1 SSR that is Stuck Open

If 24 VDC is present, the relay is receiving

voltage.

DANGER: A high-voltage capacitor is located

near this relay. Contact with the high-voltage

capacitor could result in serious injury or death.

If either/both of the relays fail to receive

voltage, replace the control board and test

the oven. If both relays are receiving 24

VAC, pull the oven out of the cabinet to

test the K9, K1, and K8 relays, as well

as the heating elements.

Before servicing:

a) Remove power from the oven.

b) Discharge the high-voltage capacitors.

c) Disconnect the primary voltage wiring of the

high-voltage transformers.

Testing Relay 14 (Pre-Heat) Operation (Gen 2)

1. After completing safety instructions above,

reconnect power to the oven and turn the

CookWheel to Bake.

1. Turn the CookWheel to Bake to begin the

preheat cycle.

2. Apply the amprobe to the wire on terminal

RBJ11 and conﬁrm a measurement of approxi-

mately 9 amps is present. If 0 amps is present,

ensure the pre-heat element is not faulty by

checking the L1 voltage at terminal RBJ-10 to

ground and RBJ-11 to ground (of the relay

board). If voltage is present, continue.

2. e solid state relay is unable to be checked with

an ohm test for continuity. Test for voltage

through the switch by energizing the relay and

leaving the brown wires connected, but pulled

back enough to get a meter probe on the

terminal.

NOTE: L1 voltage enters the relay board from the

high limit switch at terminal RBJ-10 and leaves

through RBJ-11.

CAUTION: DO NOT touch the meter leads

together; this will cause the relay to short.

3. Set the meter to AC volts. A reading of 0

indicates a closed switch, and a reading of 208/

240 indicates an open switch.

Testing for a K9 Relay that is Stuck Open

2. Turn the CookWheel to Bake to activate the K9

relay; it should make an audible click if

functional.

Heating System, Lower Oven

e lower oven heating elements require 208-240

VAC to operate.

NOTE: e K9 relay uses 120 VAC to activate the

coil.

3. Apply the probes of the multi-meter to the

common and N.O. terminals of the K9 relay

that are now exposed. ey should register

continuity with an ohms test. If they do not,

NOTE: e elements are voltage speciﬁc and cannot

operate properly without the correct voltage applied.

compartment. Brown, blue, and white wires will

be traveling together on the far left side of the oven

frame.

seven cooking settings, the control board sends

voltage to activate the relays, which supply power to

the heating elements. L1 voltage for the bake and

convection elements are supplied through the K11

SSR and the L1 voltage for the inner and outer broil

elements is supplied through the K12 SSR. e L2

voltage for all three elements is supplied from the

N.O. contact on the K13 relay.

4. Verify that no amperage is being drawn to the

elements. If any amperage is present, the K13

relay is functioning because it is the single

source of L2 voltage to all three elements.

erefore, testing should begin with L1 voltage

reaching the elements.

If the oven is not heating normally, use the below

troubleshooting option that best describes the

situation.

5. Check the high limit switch in the lower

electrical compartment to see if it tripped.

If so, press the red button to reset the switch.

is section contains information on the following

topics:

- Lower oven heating element speciﬁcations

- No heat/slow to heat

- Testing for voltage to activate the K11 SSR

- Testing for voltage to activate the K12 SSR

- Testing for a K11 SSR that is stuck open

- Testing for a K12 SSR that is stuck open

- Testing for a K13 relay that is stuck open

6. Use the amp-meter on the brown wire in the

upper electrical compartment again to verify

the elements are drawing current.

7. If the oven is still not heating, test for which leg

of power is not reaching the elements.

8. Turn the oven mode dial to oﬀ, then access the

K13 relay behind the right side lower electrical

compartment access panel.

Testing for Control Voltage to the K12 SSR

1. Turn the oven mode dial to Bake to begin

preheating. e oven should immediately make

an audible ‘click’ when the K13 relay closes.

1. Turn the oven mode dial to Bake to begin the

preheat cycle.

2. For Gen 1 ovens, apply the voltmeter probes to

P9-3 and P9-13, then to P9-3 and P9-14 (of the

control board). For Gen 2 ovens, apply

voltmeter probes to terminals RBJ17-5 and

RBJ17-3, then RBJ17-5 and RBJ17-4 (on the

relay board). e voltage reading for each should

be 24 VDC.

2. After 2-3 minutes, the oven should heat

noticeably. If no heat is present, pull the oven

11” (280 mm) from the cabinet to access the

front half of the upper electrical compartment

and the left and right lower electrical

compartment access panels.

3. Using an amp-meter, test the brown wire on the

left side of the upper electrical compartment.

Testing for a K11 SSR that is Stuck Open

Testing for a K13 Relay that is Stuck Open

1. Ensure the oven mode dial is in the oﬀ position.

1. Disconnect the two L2 blue wires from the K13

N.O. switch and the two L2 blue wires from the

K13 common. Turn the oven mode dial to Bake

to activate the K13 relay.

2. Pull the insulated wire terminals back, but not

oﬀ, to expose the terminal on all four brown

wires of the relay.

2. Apply the probes of the ohmmeter to the

common and N.O. terminals of the K13 relay

that are now exposed. ey should register

continuity. If they do not, verify the relay is

receiving control voltage from the blue wires

that are still attached to the relay in the upper

left corner.

3. Turn the oven mode dial to Bake to activate the

relay.

4. Apply the probes of the multi-meter across the

A1 and A2 terminals and B1 and B2 terminals

individually. A 208/240 reading will show an

open relay, 0 will show a closed relay.

3. If control voltage is present, replace the relay

and test the oven. If no voltage is present,

investigate for broken wires.

Testing for a K12 SSR that is Stuck Open

1. Ensure the oven mode dial is in the oﬀ position.

4. If the K13 relay is receiving control voltage and

is closing normally, L2 voltage is reaching the

elements. e K11 and K12 solid state relays

will probably not both short in the open state,

so test the control board for control voltage

reaching the K11 and K12 SSR.

2. Pull the insulated wire terminals back, but not

oﬀ, to expose the terminal on all four brown

wires of the relay.

3. Turn the oven mode dial to Broil to activate the

relay.

4. Apply the probes of the multi-meter across the

A1 and A2 terminals and B1 and B2 terminals

individually. A 208/240 reading will show an

open relay, 0 will show a closed relay.

A.6 APPENDIX - REPLACING OVEN COMPONENTS

Component and Assembly Location, DWO Gen 1 and Gen 2

DANGER: Before removing or replacing any oven component, ensure the oven is removed from any

power source (i.e., the breaker is turned oﬀ). Failure to do so can result in serious injury or death.

WARNING: Before removing or replacing any oven component, thoroughly read the safety instructions

found at the front of this manual and in Oven Systems (Section 5) and Troubleshooting (Section 6). Adhere to

all precautions and warnings outlined in these sections, as failure to do so could result in serious injury or death.

CAUTION: Before removing/installing any component, make sure it is disconnected from the wire

harness (where applicable).

Removing the Oven

In order to remove the oven from the wall, the two mounting screws (P/N: 104184), located on the inside of

the Speedcook oven’s outer trim, must be removed (additionally, some older DWO oven models have 2

cabinet screws in the lower oven’s outer trim). e oven may be safely pulled away from the wall approximately

11” (280 mm) to remove the front top cover, lower EC access panel, and the door switch covers. Any further

removal requires the oven to be fully removed from the wall and placed upon a cart capable of supporting

approximately 410 lbs (186 kg).
