Sound Information
Normal Operating Sounds
This new refrigerator may be replacing a differently
designed, less efficient or smaller refrigerator.
Today’s refrigerators have new features and are more
energy efficient. As a result, certain sounds may be
unfamiliar. These sounds are normal and will soon
become familiar. These sounds also indicate the
refrigerator is operating and performing as designed.
• Freezer and fresh food fan air rushes and whirs.
• Sealed system (evaporator and heat exchanger)
refrigerant flow gurgles, pops or sound like boiling
water.
• Defrost heater sizzles, hisses or pops.
• Condenser fan air rushes and whirs.
• Compressor has a high pitched hum or pulsating
sound.
• Ice cubes from ice maker drop into ice bucket.
• Ice maker water valve hookup buzzes when ice
maker fills with water. This occurs whether or not
refrigerator is connected to water supply. If
refrigerator is not connected to water supply, stop
sound by raising ice maker arm to off position.
• Foam insulation is very energy efficient and has
excellent insulating capabilities. However, foam
insulation is not as sound absorbent as previously
used fiberglass insulation.

System Diagnosis
Refrigerant Overcharge Symptoms
• Above normal freezer temperature.
• Compressor running continuously.
• Freezing in refrigerator due to Chef’s Pantry™
.• High suction and head pressure.
Restriction Symptoms
• Refrigeration cooling occurs on low pressure side of
partial restriction.
• Total restriction will stop circulation of refrigerant and
no cooling will occur.
• High wattage.
• Touch refrigeration lines. Most common place for
restriction is at drier filter or capillary tube inlet or
outlet.
• If partial restriction there will be temperature
difference at restriction point. Evaporator side will be
cooler. In most cases, frost and/or condensation will
be present. Longer time is required for system to
equalize.
• Kinked line will cause restriction. Visually check entire
system for kinks.
• Slight restriction will give same indications as
refrigerant shortage with lower than normal back
pressure, head pressure, wattage, and warmer
temperatures.
• Warm evaporator inlet and outlet temperature.
• Below ambient suction tube temperature. Check for
separated heat exchanger when suction temperature
is colder than ambient.
• Refrigerant will flood out causing suction line to frost
or sweat, if defrost system fails and cooling coil is not
defrosted. Correct problem instead of purging
refrigerant.
• Freezer colder than necessary (normal package
temperature is 0° to 2°F).
• Evaporator fan motor not running.
Refrigerant Shortage Symptoms
• Rise in refrigerator and freezer temperatures.
Warm beverages will be first indication of
possible refrigerant shortage. Frozen meats and
vegetables will not thaw immediately. Some freezing
may occur in refrigerator section due to additional run
time because of Chef’s Pantry™. Capillary line will not
have full column of liquid with refrigerant shortage. A
noticeable hissing sound in evaporator will be heard.
Hissing should not be mistaken for regular refrigerant
boiling sounds.
• If total restriction is on discharge side of compressor,
higher than normal head pressures and wattages will
occur. This is only true while low side is being pumped
out and if restriction was between compressor and
first half of condenser.
Diagnose restriction by completing the following:
1. Discharge system.
2. Replace drier-filter.
3. Evacuate and recharge system with specified
refrigerant charge.
• Long or continuous run time.
• Traces of oil caused by leak or cracked refrigerant
line.
If refrigerator performs normally, the following
conditions may exist:
• Lower than normal wattage.
• refrigerant loss
• Compressor will feel hot due to heat generated by
motor windings from continuous running. Compressor
will not be as hot as it would be with full charge and
long run times caused by reasons such as dirty
condenser.
• Condenser will feel room temperature.
• Capillary tube will feel warmer than normal.
• If high side leak, both gauges will show lower than
normal readings. As charge becomes less, readings
will lower. Suction pressure gauge will probably
indicate a vacuum.
• If low side leak, suction pressure gauge will show
lower than normal readings, probably in a vacuum.
Head pressure gauge will show higher than normal.
Readings will probably rise because of air drawn in
through leak is compressed by compressor and
accumulates in high side (condenser) of system.
• Partial frosting of evaporator.
• partially restricted drier
• moisture in system
If refrigerator performs as previously described,
capillary line or condenser may be restricted. Locate
and correct restriction point.
Restriction reduces refrigerant flow rate and heat
removal rate. Total restriction may be caused by
moisture, poorly soldered joint, or solid contaminants
in system. Moisture freezes at evaporator inlet end of
capillary tube. Solid contaminants collect in drier.
Wattage drops because compressor is not circulating
normal amount of refrigerant.
If restriction is on low side suction, pressure will be in
a vacuum and head pressure will be near normal. If
restriction is on high side, suction pressure will be in a
vacuum and head pressure will be higher than normal
during pump out period. In both cases, it will take
longer than 10 minutes for head pressure to equalize
with low side after compressor stops.

System Diagnosis
When ambient temperature is below cut-in of
temperature control, compressor will not operate.
Air in System Symptoms
Air in system can be caused by low side leak or
improper servicing. If low side leak occurs,
temperature control will not achieve temperatures
and compressor will run continuously. Compressor
will eventually pump low side into a vacuum, drawing
air and moisture into system. Air and R134a do not
mix. Air pressure will be added to normal head
pressure, resulting in higher than normal head
pressures.
Drain traps will freeze in ambient temperatures of
32°F.
Heat Load Symptoms
Increased heat load can result from addition of large
supply of foods, excessive door openings, poor door
sealing, interior light remaining on, etc.
Increased heat being absorbed by refrigerant in
evaporator will affect temperature and pressure of
gas returning to compressor. Refrigerator and freezer
temperatures, power consumption, discharge, and
suction pressures are all affected by heat load.
Pressures will be higher than normal under heavy
heat load.
Determine if air is present by reading head pressure
gauge with refrigerator off and evaporator and
condenser at same temperature. Verify temperature
on condenser outlet tube. Temperature should be
within 3° or 4°F of what "Pressure and Temperature
Relationship Chart" shows for a given idle head
pressure. If temperature of condenser outlet is
considerably lower than idle head pressure of gauge,
air is in system.
Diagnose air in system by completing the following:
1. Thoroughly check for leaks.
2. Correct leak source. Do not attempt to purge air
off. This could result in an undercharged system.
3. Discharge system.
4. Replace drier-filter.
5. Evacuate and recharge system with specified
refrigerant charge.
Low or High Ambient Temperature
Installation Symptoms
Lower ambient air temperature reduces condensing
temperature and temperature of liquid entering
evaporator. Increase in refrigeration due to operation
in lower ambient results in decrease in power
consumption and run time. At lower ambients there is
reduction in cabinet heat leak which is partially
responsible for lower power consumption and run
time.
An increase in refrigeration will not occur below
certain minimum ambient temperature. Temperature
varies with type and design of refrigerator.
Ambient temperatures lower than 55°F will affect
efficiency. The higher the ambient temperature, the
higher the head pressure must be to raise the high
side refrigerant temperature above condensing
medium. Head pressure will be higher as ambient
temperature raises. Refrigerators installed in ambient
temperatures lower than 55°F will not perform
effeciently because system pressures are generally
reduced and unbalanced. Lower head pressure forces
less liquid refrigerant through capillary line, resulting
in symptoms of refrigerant shortage. The lower the
ambient temperature, the more pronounced the
condition.

HFC134a Service Information
HFC134a is alternative refrigerant for CFC12.
HFC134a has an ozone depletion potential (ODP)
factor of 0.0 and a global warming potential (GWP)
factor of 0.27. HFC134a is not flammable and has
acceptable toxicity levels. HFC134a is not
interchangeable with CFC12. There are significant
differences between HFC134a and CFC12 which
must be considered when handling and processing
refrigeration system.
Caution
To minimize contamination, exercise extreme
care when servicing HFC134A sealed systems.
• No trace of other refrigerants is allowed in HFC134a
systems. Chlorinated molecules in other refrigerants
such as CFC12, etc. will lead to capillary tube
plugging.
• Ester oil is used in HFC134a systems. Do not use
mineral oil. HFC134a and mineral oils cannot be
mixed. If mineral oils were used in HFC134a systems,
lubricant would not return to compressor and would
cause early compressor failure. If significant amount
of oil has been lost from compressor, replace oil
rather than adding oil.
Health, Safety, and Handling
Health, safety and handling considerations for
HFC134A are virtually no different than those for
CFC12.

• CFC12 has much higher tolerance to system
processing materials, such as drawing compounds,
rust inhibitors, and cleaning compounds, than
HFC134a. Such materials are not soluble in HFC134a
systems. If materials were to be washed from system
surfaces by ester oils, they could accumulate and
eventually plug capillary tube.
Arrhythmias
Safety and handling
Spill management
Wear appropriate skin and eye
protection. Use with adequate
ventilation.
Remove or extinguish ignition or
combustion sources. Evacuate
or ventilate area.
• Care must be taken to minimize moisture from
entering HFC134a system. Do not leave compressor
or system open to atmosphere for more than 10
minutes. Excessive moisture in HFC134a system will
react with compressor oil and generate acid.
• Compressor must be replaced when performing low
side leak repair.
Fire and explosion hazards
May decompose if contact with
flames and heating elements.
Container may explode if heated
due to resulting pressure rise.
Combustion products are toxic.

Comparison of CFC12 and HFC134a
Properties
Important: Unbrazing drier filter from tubing will drive
moisture from desiccant and into system, causing
acids to form. Do not unbraze filter drier from tubing.
If CFC12 service drier was installed in HFC134A
system, drier could overload due to excessive
moisture.

HFC134a Service Information
Service Equipment
Drier Replacement
Prior to opening refrigeration system, recover
HFC134a refrigerant for safe disposal.
Listed below is equipment needed for proper
servicing of HFC134a systems. Verify equipment is
confirmed by manufacturer as being compatible with
HFC134a and ester oil system.
Every time sealed HFC134a system is repaired, drier
filter must be replaced with, part # B2150504.
Equipment must be exclusively used for HFC134a.
Exclusive use of equipment only applies to italic
items.
Cut drier out of system by completing the following
steps. Do not unbraze drier filter. Applying heat to
remove drier will allow moisture into system.
1. Score capillary tube close to drier and break.
2. Reform inlet tube to drier allowing enough space
for large tube cutter.
• Evacuation pump
Check with vacuum pump supplier to verify
equipment is compatible for HFC134a. Robinair,

HFC134a Service Information
Replacement Service Compressor
WARNING
HFC134a service compressors will be charged with
ester oil and pressurized with dry nitrogen. Before
replacement compressor is installed, pull out 1 rubber
plug. A pop from pressure release should be heard. If
a pop sound is not heard, do not use compressor.
Positive pressure in compressor is vital to keep
moisture out of ester oil. Do not leave compressor
open to atmosphere for more than 10 minutes.
To avoid death or severe personal injury, never
use oxygen, air or acetylene for pressure testing
or cleanout of refrigeration system. Use of
oxygen, air, or acetylene may result in violent
explosion. Oxygen may explode on contact with
oil and acetylene will spontaneously explode
when under pressure.
Evacuation and Charging
Compressor Testing Procedures
• Refer to “Temperature and Relationship Chart” for
operating watts, test points, and temperature
relationship test.
• Temperature testing is accomplished by using 3 lead
thermocouple temperature tester in specific locations.
Test point T-1 is outlet on evaporator coil and T-2 is
inlet. Test point T-3 is suction tube temperature
midway between where armaflex ends and suction
port of compressor (approximately 12 inches from
compressor).

• Turn control to colder to obtain required on time.
• Wattage reading must be recorded in conjunction with
temperature test to confirm proper operation.
• Suction and head pressures are listed on
“Temperature and Relationship Chart” Normally these
are not required for diagnosis but used for
confirmation on systems which have been opened.
Refrigerant Charge
Refrigerant charge in all capillary tube systems is
critical and exact amount is required for proper
performance. Factory charges are shown on serial
plate. Do not use refrigerant other than shown on
serial plate.
Leak Testing
Undetected leaks lead to repeated service calls and
eventually result in system contaminations,
restrictions, and burned out compressors.
After recharging, sealed system must be thoroughly
tested for leaks. If a very small leak is difficult to
isolate, coat area with soap suds and observe
location of bubbles.

WARNING
manifold gauge) and pinch off high side drier
process tube.
To avoid severe personal injury or death from
fire keep system free from contamination due
to presence of air. Follow instructions exactly.
10. Start compressor and draw remaining refrigerant
in charging hoses and manifold into compressor
through compressor process tube. To check high
side pinch-off drier process tube, close valve “D”
(high side gauge). If pinch-off is not leaking, high
side pressure will not rise. If high side pressure
gauge shows an increase, repeat high side pinch-
off and open valve “D”. Repeat until high side
pinch-off no longer leaks.
11. Pinch-off compressor process tube and remove
charging hose. Braze stub closed while
compressor is operating.
12. Unplug refrigerator from electrical outlet.
Remove charging hose and braze high side drier
process tube closed.
Before opening system evaporator coil must be at
ambient temperature to minimize moisture infiltration
into system.
1. After capturing refrigerant, replacing drier and
making any repairs, evacuate system from high
side through drier/process tube and low side
through compressor process tube simultaneously.
Evacuation should not be done through line
piercing valve but through I.D. opening of tubes.
2. With valves “C” and “F” closed to thermistor
vacuum gauge and charging cylinder, open all
other valves and start vacuum pump.
3. At approximately 29 inches of vacuum, open valve
“C” to thermistor vacuum gauge and take micron
reading.
4. Continue evacuating system until thermistor
vacuum gauge registers 600 microns.
5. At 600 microns close valve “A” to vacuum pump to
allow micron reading in system to balance. Micron
level will rise. If in 2 minutes, micron level
stabilizes at 1000 microns or below, system is
ready for charging.
• If micron rises above 1000 micron level and
stabilizes, open valve “A” to vacuum pump and
continue evacuating.
• If micron reading rises rapidly and does not
stabilize, a leak still exists in system. Close valve
“A” to vacuum pump and “C” to thermistor vacuum
gauge. Invert charging cylinder and open charging
cylinder valve “F” to add partial charge for leak
checking. With leak detector, check manifold
connections and system for leaks. After locating
leak, capture refrigerant charge, repair leak, and
begin at step 1.
6. Once system is ready to charge, close valve “A”
(vacuum pump), “C” (thermistor vacuum gauge),
and “E” (low side manifold gauge).
7. Check serial plate for correct charge and set scale
on dial-a-charge cylinder for corresponding
HFC134a pressure reading. Do not use captured or
recycled refrigerant in Amana® refrigerators. Use
of captured or recycled refrigerant voids any
warranty.
8. Open valve “F” to charging cylinder and let exact
amount of refrigerant out of cylinder. Close valve.
Low side gauge pressure should rise shortly after
opening charging cylinder valve as system
pressure equalizes through capillary tube. If
pressure does not equalize, a restriction typically
exists at capillary/drier braze joint.

Component Function and Testing
Capacitor
Run capacitor connects to relay terminal.
WARNING
To avoid electrical shock w hich can cause severe personal
injury or death, discharge capacitor through a resistor before
handling.
1. Disconnect pow er to refrigerator.
2. Remove capacitor and disconnect capacitor w ires.
3. Discharge capacitor by shorting across terminals w ith a resistor for
1 minute.
4. Check resistance across capacitor terminals w ith ohmeter set on
"X1K" scale.
• Needle should jump tow ards 0 ohms and quickly move back to
infinity.
• If needle does not move, the capacitor is open.
• If needle reads a constant value at or near 0 ohms, the capacitor is
shorted.
• If needle jumps tow ards 0 and then moves back to a constant high
resistance (not infinity), the capacitor has a high resistance leak.
Capillary tube
Capillary is sized in diameter and length to
feed proper amount of refrigerant to
evaporator.
Capillary is soldered to suction line to transfer
heat from capillary and add additional
superheat to gas refrigerant in compressor
suction line.
Capillary discharges into evaporator.
Compressor
When compressor electrical circuit is energized, the
start w inding current causes PTC relay to heat. After an
amount of starting time the start w inding circuit turns
off. PTC relay will sw itch off the start w inding circuit
even though compressor has not started (as w hen
attempting to restart after momentary pow er
interruption).
Check for resistance betw een:
Terminals "S" & "C"
Terminals "R"& "C"
Ground Test
Disconnect pow er to refrigerator .Remove compressor leads and use an
ohmmeter set on highest scale. Touch 1 lead to compressor body (clean
point of contact) and the other probe to each compressor terminal. If a
reading is obtained, compressor is grounded and must be replaced.
With "open" PTC relay, compressor w ill not start
because there is little or no current to start w indings.
Overload protector w ill open due to high locked rotor
run w inding current.
Operation Test
If motor w inding tests fail to show cause for failure:
1. Disconnect pow er to refrigerator. Wire a test cord to disconnect
sw itch.
2. Place time delayed fuse, w ith U.L. rating equal to amp rating of motor,
in test cord socket.
With "shorted" PTC relay or capacitor, compressor w ill
start and overload protector w ill quickly open due to
high current of combined run and start w indings.
3. Remove overload and relay.
4. Connect start, common, and run leads of test cord on appropriate
terminals of compressor.
With open or w eak capacitor, the compressor w ill start
and run as normal but w ill consume more energy.
5. Attach capacitor leads of test cord together. If capacitor is used,
attach capacitor leads to a good capacitor of same capacity.
6. Plug test cord into volt-w att meter to determine start and run w attage
as w ell as check for low voltage w hich can also be a source of
trouble.
7. With pow er to volt-meter, press start cord sw itch and release. If
compressor motor starts and draw s normal w attage compressor is
okay and trouble is in capacitor, relay, overload, freezer temperature
control, adaptive defrost control, or elsew here.

Component Function and Testing
Condenser
Condenser is a tube and w ire construction located in
compressor compartment. Condenser is on high
pressure discharge side of compressor.
• Leaks in condenser can usually be detected by using an electronic
leak detector or soap solution. Look for signs of compressor oil w hen
checking for leaks. A certain amount of compressor oil is circulated
w ith refrigerant.
Refrigerant flow s from compressor into a pre-
condenser serpentine below drain pan to evaporate
defrost w ater. From serpentine, refrigerant flow s into
pre-condenser loop (Yoder loop) foamed around
freezer door opening to help control external
• Leaks in post condenser loop are rare as loop is a 1 piece copper
tube.
• In cases of minute leaks it may be necessary to separate condenser
from rest of refrigeration system and pressurize condenser up to a
maximum of 235 PSI w ith a refrigerant and dry nitrogen combination.
condensation around freezer door and on flange.
Higher pressure refrigerant gas is routed to condenser
w here as gas temperature is reduced, gas condenses
into high pressure liquid state. Heat transfer takes place
because discharged gas is at higher temperature than
air that is passing over condenser.
WARNING
To avoid severe personal injury or death observe the follow ing:
• Protect against a sudden eruption if high pressures are
required for leak checking.
•
High pressure compressed cases should never be used in
refrigeration systems w ithout a reliable pressure regulator and
pressure relief valve in the lines.
Condenser is air cooled by fan motor. It is very
important that adequate air flow over condenser is
maintained. If efficiency of heat transfer from
condenser to surrounding air is impaired, condensing
temperature becomes higher. Higher temperature liquid
means less heat w ill be removed during boiling in
evaporation. This is indicated by higher that normal
head pressures, long run time, and high w attage.
Remove any lint, dust accumulation, etc. that w ould
restrict normal air movement throughout the condenser.
Drier
Drier is placed at P.C. loop outlet and passes liquified refrigerant to
capillary.
Desiccant
(20) 8 X 12 4AXH - 7 M.S. - Grams
Drier must be changed w henever sealed refrigeration system is opened.
Drier used in R12 sealed system is not interchangeable w ith drier used in
R134a sealed system. Replace drier w ith part #B2150504.
Evaporator
Leaks in evaporator can usually be detected by the use of electronic leak
detector or soap solution. Compressor oil is circulated w ith refrigerant so
look for oil w hen checking for leaks.
Inner volume of evaporator allow s liquified refrigerant
discharged from capillary to expand into refrigerant
gas.
For minute leaks separate condenser from rest of refrigeration system
and pressurize condenser up to a maximum of 140 PSI w ith a refrigerant
and dry nitrogen combination. Recheck for leaks.
Act of expansion cools evaporate tube and fin
temperature to approximately -20°F, transfering heat
from freezer section to refrigerant.
Passing through suction line to compressor, the
refrigerant picks up superheat (a relationship betw een
pressure and temperature that assures complete
vaporization of liquid refrigerant) as result of capillary
being soldered to suction line.
Refrigerant gas is pulled through suction line by
compressor to complete refrigerant cycle.

Electronic Functional Description
As the temperature decreases, resistance increases.
Adaptive Defrost Operation
As the temperature increases, resistance decreases.
An open thermistor or thermistor circuit will result in
failure of refrigerator to cool. Shorted thermistor will
result in refrigerator to run 100 percent of time except
for defrost.
• Defrost occurs after predetermined length of
compressor run hours. Compressor run time
between defrost changes or adapts, depending upon
recent history of defrost lengths (time it takes for
defrost terminator to open once defrost heater has
been turned on). Defrost terminator opens at 55°F
(13°C) and closes at 20°F (-7°C).
• Compressor run time between defrost (CRTD) will
be one of 3 values under normal operation: CRTD
(1), or CRTD (2) or CRTD (3) defined as 8, 12, and
16 hour lengths. If defrost length is low (DT-LO
defined as 21 minutes) indicating small frost load
CRTD for next defrost cycle is advanced to next
level. If defrost length is high (DI - HI defined as 24
minutes) indicating large frost load CRTD for next
defrost cycle is lowered to next level. Initial value at
power CRTD (0) is 4 hours.
• Freezer temperature setting and thermistor value
will determine if compressor/condenser fan and
evaporator fan switches are open or closed.
Compressor/condenser fan switch must be open for
6 minutes before switch can close again
(compressor dwell time).
• Refrigerator temperature setting and thermistor
value will determine if fresh food fan switch is to be
open or closed.
• Cutout and cutin temperature values must be
reached and maintained for 15 seconds before
output state will change (digital delay).
• Vacation mode CRTD equals 96 hours. Vacation
mode CRTD is interrupted with door openings.
Defrost interval will revert back to the previous
interval before Vacation mode.
• Six minute dwell time occurs after defrost terminator
opens before compressor and condenser fan motor
will operate. Ten minute dwell time occurs after
defrost terminator opens before evaporator fan
motor will operate.

Electronic Functional Description
Circuitry
Refer to “Technical Data Sheet”, part #12074201, for Wiring Schematic.
Freezer Compartment Refrigeration Cycle Circuitry
As freezer thermistor warms, resistance lessons, allowing low voltage signal to be sent to electronic control. In
turn, 2 low voltage signals are sent by electronic control. One to compressor relay coil (C1) and another to
evaporator fan relay coil (F1). With both relay coils energized and contacts closed, high voltage circuits to
compressor, condenser fan motor, and evaporator fan motor are complete.
As thermistor cools during refrigeration cycle, resistance through thermistor increases, blocking low voltage
signal to electronic control, interrupting the cycle.
Fresh Food Compartment Refrigeration Cycle Circuitry
As fresh food thermistor warms, resistance lessens, allowing low voltage signal to be sent to electronic control.
In turn, electronic control sends low voltage signal to 24 VDC fresh food fan.
When fresh food fan motor operates, freezer air is circulated into fresh food compartment. As fresh food
thermistor cools, resistance increases, blocking low voltage signal to electronic control. In turn, electronic
control interrupts the signal to fresh food fan motor.
Fresh Food and Freezer Compartment Refrigeration Cycle Circuitry
Many times cooling will be called for in both compartments as both freezer and fresh food thermistors warm.
Resulting is electronic control signaling for compressor, condenser fan motor, evaporator fan motor, and 24
VDC fresh food fan to operate. Once freezer thermistor has been cooled sufficiently to block the signal to
electronic control, the compressor, condenser fan motor, and evaporator fan motor will shut down. However,
fresh food fan motor will continue to function until fresh food thermistor cools and blocks the signal to electronic
control.
If fresh food thermistor is cooled prior to freezer thermistor, the electronic control will interrupt the signal to the
fresh food fan motor. The compressor, condenser fan motor, and evaporator fan motor will remain in operation
through freezer thermistor.
Adaptive Defrost Circuitry
After proper compressor run time (either 8, 12, or 16 hours), refrigeration cycle is interrupted and a low
voltage signal is sent form electronic control to defrost relay coil (D1 DEF). Powering of relay coil closes relay
contact (D1), completing the high voltage circuit to the defrost heater through the closed defrost terminator
(closes at 20°F (-7°C)). The isolator, part of high voltage PC board, recognizes the presence of line voltage to
the defrost heater. Isolator sends a low voltage signal to electronic control which keeps count of the number of
minutes defrost terminator remains closed (opens at 55°F (13°C)). Length of time defrost terminator remains
closed, determines whether next defrost cycle advances by 4 hours of compressor run, stays at same interval or
backs up by 4 hours of compressor run. If defrost terminator does not open before 30 minutes, defrost cycle will
automatically be terminated by electronic control and refrigeration cycle will resume after a 6 minute dwell time.
Important: When Showroom switch is off, isolator see's line voltage. In turn, isolator keeps electronic controller
from signaling compressor, condenser fan motor, and evaporator fan motor relay coils and keeps fresh food fan
motor off.

Ice Maker
Specifications
Mold heater: 185 watts, 264 ohms
Thermostat: Close 17 ± 3°F (-8 ± 1°C)
(bimetal)
Opens 32° ± 3°F (0°± 1°C)
Water fill:
140 cc, 7.5 sec.
Motor cycle: Stamped in circuit.
Plug in connectors.
One revolution of blades takes
3 minutes plug stall time on ice
(eject and water fill).
Testing Procedures
Verify ice maker has power, shut-off arm is down, and
freezer is cold enough to close bimetal thermostat.
• Test point L and N will verify 120 volts to ice maker
module.
• Test points T and H will verify bimetal thermostat is
open or closed.
Operation
Thermostat closes when temperature reaches
17° ± 3°F (-8.3° ± 1.5°C). Current flows through
thermostat to motor. See “Ice Maker Wiring
Diagram”. Motor is linked with drive gear. From
module, there are copper contacts that ride on copper
strips on backside of drive gear. As the drive gear
rotates, contacts will make or break a circuit (tract) to
the copper strips to operate ice maker.
• Verify test probes go into test points 1/2 inch
(1.25 cm).
1. Short T and H with a shunt (insulated 14 gauge wire
with ends stripped back 5/8 inch (1.6 cm)) to run
motor. If motor runs, replace bimetal thermostat. If
motor does not run, replace module.
All components can be tested without removing ice
maker or moving refrigerator away from installation.
Remove cover.
Test points are identified on module:
N = Neutral side of line
M = Motor connection
H = Heater Connection
T = Thermostat connection
L = L1 side of line
2. Leave jumper in for half of revolution. Touch
heater mold. If heater mold feels warm, heater is
working properly.

Water Fill Adjustment
Turning water level adjustment screw will move
contact in relationship with contact ring segment. This
causes contact to vary time water valve is energized.
Contact ring is tapered at end of fill time.
Switches will jam if turned counterclockwise and
gears will be destroyed if turned clockwise. Advance
ice maker into cycle by using a jumper to bridge H to
R. Ice maker will not run if motor is defective. Shut-off
arm must be in on position.
There are several slotted shafts on motor assembly
board. Do not insert screwdriver and attempt to turn
shafts. Slots permit assembly only.
There are nonrepairable and nonreplaceable
components in module. When diagnosing or repairing
ice maker, do not remove module unless replacing
module.
• Turning screw clockwise decreases fill time.
• Turning screw counterclockwise increases fill time.
• 1/2 turn equals 20 cc or 1.2 seconds.
• Full turn equals 40 cc or 2.4 seconds.

Ice Maker
Thermostat, mold heater, and wiring harness are
replaceable. Any other failure, including motor,
requires replacement of module assembly.
Replacement mold assembly comes with new mold
heater installed.
Caution
To avoid module damage do not rotate water
adjustment screw more than one full turn in
either direction.
Thermostat
1. Remove control box from mold by removing
screws.
If water valve adjustment screw falls out, put screw in
hole and align as shown below.

2. Pull front of black housing free of mold.
Thermostat is on mold side.
Thermostat
When small hole is centered in large hole, water fill
adjustment is 7.5 seconds (normal fill time).
Water Problems
Poor water quality can cause ice maker to fail or
produce unacceptable cubes. Mineral content or sand
can restrict screen in water fill valve or particle of
sand can keep valve from seating properly.
Retaining clips
3. Grasp 1 thermostat clip and pull out.
4. Press in new thermostat. Verify pins are properly
indexed. Electrical assembly does not need to be
removed.
If water valve does not close, the following could
occur:
• no ice production
If replacing module, transfer clips to new mold
support. Use new thermal bonding material.
• small or hollow ice cubes
• flooding of ice container
Install water filter, part #R0183114, to eliminate bad
taste, odor, and visible contaminates.
Wiring Harness
Remove wiring harness by pressing retaining tab
and pulling forward.
Mineral contact can cause lime build up in mold.
Wicking of water over mold and poor cube release
can occur. Silicone is applied at upper edges around
fill cup and stripper.
Temperature Problems
Freezer temperatures above normal 0° ± 2°F
(-18°±1°C) will slow down ice production. Increase ice
production by setting freezer to colder setting.
Thermostat cycling temperature (1 revolution ice
maker) is 17° ± 3°F (-8° ± 1°C). Ice will freeze when
these temperatures are achieved. Cycling time will be
slower if freezer temperature is not cold enough to
achieve mode temperatures easily.

Ice Maker
Caution
To avoid property damage, test for water
leaks after repair or replacement of water
valve. Do not overtighten connection to
household water supply.
Water Valve
Water valve has 1 solenoid. Valve has 80 mesh
screen water strainer. When tan encapsulated
solenoid is energized, the amount of water entering
ice maker mold is directly proportional to length of
time water valve switch is held closed by timing cam.
Inside valve is a flow washer which acts as a water
pressure regulator. Proper ice maker fill is 140 cc
± 10cc at 7.5 seconds of water fill at an inlet pressure
ranging from 20 to 120 PSI (1.4 to 8.2 bar).
Wiring Harness
A nonresettable thermal fuse micro device 170°F
(78°C) is spliced into red wire of ice maker wiring
harness. Fuse will protect freezer plastic liner from
melting if ice maker should overheat. Excessive heat
can cause no ice production. Replacing wiring
harness will only temporarily solve problem. Replace
ice maker thermostats.
