WIRING
Electrical Requirements
Built-in power leads are UL approved for connection
GROUNDING SPECIFICATIONS
to larger gauge household wiring. The insulation of
these leads is rated at temperatures much higher
than the temperature rating of household wiring.
The current carrying capacity of a conductor is
governed by the temperature rating of the insulation
around the wire rather than the wire gauge alone.
Ground Path Resistance 0.10 Ω Max.
Insulation Resistance 250K Ω Min.
POWER SUPPLY REQUIREMENTS
The cooktop must be connected to a supply circuit
of the proper voltage and frequency as specified
on the nomenclature tag. Wire size must conform
to the National Electrical Code or the prevailing
local code. The nomenclature tag is located on the
bottom of the burner box.
WARNING: Improper connection of aluminum house
wiring to these copper leads can result in a serious
problem. Use only connectors designed for joining
copper to aluminum and follow the manufacturer’s
recommended procedure closely.

The branch circuit load for 1 wall-mounted oven
or 1 counter-mounted cooktop is the rating on the
nomenclature tag of the appliance.
You must use a 2-wire, 3-conductor, 208/240 VAC,
60 Hertz electrical system. A white (neutral) wire
is not needed for this unit. The cooktop must be
installed in a circuit that does not exceed 125 VAC
nominal to ground.
The branch circuit load for a counter-mounted
cooktop and not more than 2 wall-mounted ovens―
all supplied from a single branch circuit and located
in the same room―shall be computed by adding the
nameplate ratings on the individual appliances and
treating this total as equivalent to 1 range.

COOKING
NOTE: A slight odor is normal when a new
cooktop is used for the first time. It is caused by
the heating of new parts and insulating materials
and will disappear in a short time.
elements beneath a smooth glass surface.
Cooktop temperatures increase with
the number of surface elements that
are on. With 3 or 4 elements turned on,
cooktop temperatures are high. Always
use caution when touching it.
It is safe to place hot cookware (from
the oven or surface) on the glass cooktop
when the surface is cool. Never place
cookware on the control area.
Never cook directly on the glass.
Always use cookware.
The indicator lights will come on
next to the Dual and Tri-Ring burners
when activated. Lights also activate for
the Control Lock feature when it is
turned on. The indicator lights will
go off when the surface element or
feature is turned off.
OFF CENTER
Even after the surface elements are
turned off, the glass cooktop retains
enough heat to continue cooking. To
avoid overcooking, remove pans from
the surface elements when the food is
cooked. Avoid placing utensils that could
become hot or plastics that could melt
on the surface element until it has cooled
completely.
Always center the pan on the surface
element you are using.
The appropriate HOT SURFACE indicator
light will glow when its corresponding
radiant element is turned on and will
remain on until the surface has cooled
to approximately 150°F.(66°C).
DRAGGING
■ Water stains (mineral deposits) are removable
using the cleaning cream or full strength white
vinegar.
NOTE:
■ Use of window cleaner may leave an
iridescent film on the cooktop. The cleaning
cream will remove this discoloration.
Hot surface indicator light will:
■ Come on when the surface element is
turned on.
■ Stay on even after the element is turned off.
■ Glow brightly until the element has cooled
below 150°F. (66°C).
Do not slide cookware across the
control or cooktop surface because
it can scratch the glass. The glass is
scratch-resistant, not scratchproof.
■ Don’t store heavy items above the cooktop.
If they drop onto the cooktop, they can cause
damage.
■ Do not use the surface as a cutting board.
Radiant Surface Elements
The controls for the radiant surface
elements allow for 11 different heat
settings: Low, 1–9 and High. The heating
element may not visibly glow at low heat
settings.
The surface heating element will cycle on
and off to maintain your selected control
setting.
Each radiant surface element has a
temperature limiter which protects the
glass cooktop from getting too hot.

Operation Overview
DIGITAL CONTROL SYSTEM
The digital control system consists of 3 circuit boards:
1. The touch board (permanently adhered to the ceramic glass panel) senses user input, including control
lockout, displays user settings, contains HOT lights and key touch beeper. It is the “Main” board for the
system.
2. The relay power supply module (RPSM), located inside the drop box, provides DC for touch board
communications and to relays controlling the heating elements.
3. The daughter relay module (DRM) with additional relays is located under the touch board. The touch
board communicates with the RPSM board via 12-volt serial bus. The RPSM communicates with the DRM
via individual 5-volt and 12-volt DC levels.
There are no electronic sensors. Traditional-style sensors are located in the radiant elements providing over-
temperature protection cycling and HOT lamp input to the RPSM board.
ELEMENT CONTROL
Each element is controlled by at least 2 relays. Both L1 and L2 are disconnected from the radiant elements
during standby (except the HOT lamp limiter switch). The setup relays remain constantly energized during
burner use. The cycle relays provide the duty cycling during non-HI settings. When non-Hi levels are
selected, the burners’ cycle relay will cycle 3 times per minute. When higher levels are selected, some cycling
of the element will occur due to the overtemperature limiter in the radiant element, which is in series with the
relays.
BURNER TOUCH KEYS
In standby, only the ON/OFF keys (and LOCK key) should respond. The +, –, and pan-size keys should not
respond until after the ON/OFF key has been touched first.
HOT LIGHT CHECK
The HOT lights are LEDs within the touch board. They are commanded "on" via serial bus responses from the
RPSM board to the touch board.
A HOT light glows from two sources:
1. Whenever a burner is activated, the HOT light is immediately on.
2. When the temperature of a ribbon heating element exceeds 150°F (66°C), the HOT light is on. At
temperatures over 150°F (66°C), the element's limiter switch closes, sending 240 VAC to the RPSM input at
J21 and initiating the serial bus response.
When the burner is cool to the touch and in standby, the HOT light should be off. When the burner is first
activated, HOT should glow immediately. If a burner has been on for approximately 1 minute (5 minutes for
model JP975), then returned to standby, the HOT light should remain on until cool.
Note: Due to the low wattage rating, the warming zone surface element (JP975) will not glow red even when
on highest heat setting. The warming zone surface element (JP975) does not utilize an overtemperature
limiter switch.
DEMO MODE
When 120 VAC is applied to the unit between the black and red leads, the touch board will operate normally,
but the relays and elements are prevented from operating.

DEAD UNIT: Turn off circuit breaker, wait 30 seconds, and turn circuit breaker on. Proceed to tests below.
DISPLAY CHECK: Turn burner on Level 8. All segments should light. Set 4 burners to 1, 2, 5, and 8. Check for
proper digit displays. When power is first applied, all the segments light in a sequence. Check for a consistent
pattern, none missing or doubled up.
VERSION DISPLAY: When the power is first applied, after the display test sequence, the 4-digit version
number of the touch board is momentarily shown in the display.
TOUCH KEYS IN GENERAL: Keys should respond to a grounded surface on the glass of 0.350-inch diameter,
which is the model for a finger. Keys should not respond to a grounded surface less than 0.130-inch
diameter. Water, etc., on the keys may cause them to not respond correctly because of unwanted ground
coupling. However, the OFF function will respond regardless of contamination. If the contamination is severe
enough to completely prevent touch key response, supervisory functions will turn off the burner. Removing
the contamination should restore proper key operation. After cleaning the keypad glass (ensure the keypad
is clean and dry), wait 30 - 60 seconds for keypad sensitivity to stabilize. A gap or moisture between the
touch board and glass will affect touch key performance. If this occurs, the glass assembly should be
replaced.

Element Resistance Troubleshooting
WARNING: The power must be disconnected from the cooktop.
The resistance of certain elements and the continuity of certain element circuit wiring can be tested without
removing the cooktop from its installation. This test will aid the service technician in determining if the RPSM
or the DRM should be replaced. This test assumes the touch board functions properly.

Element Hot Light Troubleshooting
Each element's hot light limiter switch and its wiring can be tested without removing the cooktop from its
installation. This test will aid the service technician in determining if the element should be replaced. This test
assumes the elements heat properly.
All circuits below element's glass top temperature of 150°F (66°C) should test open. If circuit tests 0
resistance, replace element.
All circuits above element's glass top temperature of 150°F (66°C) should test 0 resistance. If open, check
wiring and replace element, if necessary. Operate element, if necessary, then disconnect power before
testing cooktop.
