WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.
Component
Compressor
Description
When compressor electrical circuit is
energized, the start winding current
causes relay to heat. After an amount of
starting time, the start winding circuit
turns off. The relay will switch off the start
winding circuit even though compressor
has not started (for example, when
attempting to restart after momentary
power interruption).
With “open” relay, compressor will not
start because there is little or no current
to start windings. Overload protection will
open due to high locked rotor run winding
current.
With “shorted” relay or capacitor,
compressor will start and overload
protector will quickly open due to high
current of combined run and start
windings.
With open or weak capacitor,
compressor will start and run as normal
but will consume more energy.
Test Procedures
Resistance test
1. Disconnect power to unit.
2. Discharge capacitor by shorting across terminals with a resistor for 1 minute.
NOTE: (Some compressors do not have a run capacitor.)
3. Remove leads from compressor terminals.
4. Set ohmmeter to lowest scale.
5. Check for resistance between
Terminals “S” and “C”, start winding
Terminals “R” and “C”, run winding
If either compressor winding reads open (infinite or very high resistance) or
dead short (0 ohms), replace compressor.
Ground test
1. Disconnect power to refrigerator.
2. Discharge capacitor, if present, by shorting terminals through a resistor.
3. Remove compressor leads and use an ohmmeter set on highest scale.
4. Touch one lead to compressor body (clean point of contact) and other probe
to each compressor terminal.
• If reading is obtained, compressor is grounded and must be replaced.
Operation test
If voltage, capacitor, overload, and motor winding tests do not show cause for
failure, perform the following test:
1. Disconnect power to refrigerator.
2. Discharge capacitor by shorting capacitor terminals through a resistor.
3. Remove leads from compressor terminals.
4. Wire a test cord to power switch.
5. Place time delayed fuse with UL rating equal to amp rating of motor in test
cord socket. (Refer to Technical Data Sheet)
6. Remove overload and relay.
7. Connect start, common and run leads of test cord on appropriate terminals of
compressor.
8. Attach capacitor leads of test cord together. If capacitor is used, attach
capacitor lead to a known good capacitor of same capacity.

Test configuration
9. Plug test cord into wattmeter to determine start and run wattage and use a
multimeter to check for low voltage, which can also be a cause of a
compressor not starting.
10. With power to multimeter, press start cord switch and release.
• If compressor motor starts and draws normal wattage, compressor is okay
and trouble is in capacitor, relay/overload, freezer temperature control, or
elsewhere in system.
• If compressor does not start when direct wired, recover refrigerant at high
side. After refrigerant is recovered, repeat compressor direct wire test. If
compressor runs after recovery but would not run when direct wired
before recover, a restriction in sealed system is indicated.
• If compressor does not run when wired direct after recovery, replace faulty
compressor.

• Open—needle does not move. Replace capacitor.
• Shorted—needle moves to zero and stays. Replace capacitor.
• High resistance leak—needle jumps toward 0 and then moves back to
constant high resistance (not infinity).
Condenser
Condenser is a long folded tube
construction located in machine
compartment.
Leaks in condenser can usually be detected by using an electronic leak detector
or soap solution. Look for signs of compressor oil when checking for leaks. A
certain amount of compressor oil is circulated with refrigerant.

WARNING
From the condenser the refrigerant flows
into a post condenser loop which helps
control exterior condensation on flange,
center mullion, and around freezer door.
Refrigerant flows through the drier to the
capillary tube to the evaporator and back
to the compressor through suction line.

NOTE: All precautionary measures recommended by
refrigerant manufacturers and suppliers apply
and should be observed.
Attaching Capacitor for Compressor Test
Line Piercing Valves
5. Connect a known good capacitor into circuit as shown
above. For proper capacitor size and rating, see
technical data sheet for unit under test.
Line piercing valves can be used for diagnosis, but
are not suitable for evacuating or charging due to
holes pierced in tubing by valves.
NOTE: Ensure test cord cables and fuses meet
specifications for unit under test (see Technical
Sheet for unit under test).
NOTE: Do not leave line piercing valves on system.
Connection between valve and tubing is not
hermetically sealed. Leaks will occur.
6. Replace compressor protector cover securely.
Open Lines
7. Plug test cord into outlet, then press and release start
cord switch.
During any processing of refrigeration system, never
leave lines open to atmosphere. Open lines allow water
vapor to enter system, making proper evacuation more
difficult.
! CAUTION
To avoid risk of damage to compressor windings,
immediately disconnect (unplug) test cord from power
source if compressor does not start. Damage to
compressor windings occurs if windings remain
energized when compressor is not running.
Compressor Operational Test
(short term testing only)
If compressor voltage, capacitor, overload, and motor
winding tests are successful (do not indicate a fault),
perform the following test:
If compressor runs when direct wired, it is working
properly. Malfunction is elsewhere in system.
1.Disconnect power to unit.
2.Discharge capacitor by shorting capacitor
terminals through a resistor.
If compressor does not start when direct wired, recover
system at high side. After the system is recovered,
repeat compressor direct wire test.
NOTE: Not all units have run capacitor.
3.Remove leads from compressor terminals.
If compressor runs after system is recovered (but
would not operate when wired direct before recovery) a
restriction in sealed system is indicated.
4.Attach test cord to compressor windings.
• Common lead on test cord attaches to C terminal
on compressor.
If motor does not run when wired direct after recovery,
replace faulty compressor.
• Start lead on test cord attaches to S terminal on
compressor.
• Run lead on test cord attaches to M terminal on

WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a 10,000 ohm resistor before attempting
to service. Ensure all ground wires are connected before certifying unit as repaired and/or operational.
Testing Systems Containing No Refrigerant Charge
1. Connect cylinder of nitrogen, through gauge
manifold, to process tube of compressor and liquid
line strainer.
Dehydrating Sealed Refrigeration System
Moisture in a refrigerator sealed system exposed to
heat generated by the compressor and motor reacts
chemically with refrigerant and oil in the system and
forms corrosive hydrochloric and hydrofluoric acids.
These acids contribute to breakdown of motor winding
insulation and corrosion of compressor working parts,
causing compressor failure.
2. Open valves on nitrogen cylinder and gauge manifold.
Allow pressure to build within sealed system.
3. Check for leaks using soap suds.
If a leak is detected in a joint, do not to attempt to repair
by applying additional brazing material. Joint must be
disassembled, cleaned and rebrazed. Capture refrigerant
charge (if system is charged), unbraze joint, clean all
parts, then rebraze.
In addition, sludge, a residue of the chemical reaction,
coats all surfaces of sealed system, and will eventually
restrict refrigerant flow through capillary tube.
To dehydrate sealed system, evacuate system (see
paragraph Evacuation).
If leak is detected in tubing, replace tubing. If leak is
detected in either coil, replace faulty coil.

systems. Free oxygen will explode on contact with
oil. Acetylene will explode spontaneously when put
under pressure.
It is important to check sealed system for refrigerant
leaks. Undetected leaks can lead to repeated service
calls and eventually result in system contamination,
restrictions, and premature compressor failure.
Refrigerant leaks are best detected with halide or
electronic leak detectors.
Testing Systems Containing a Refrigerant Charge
1. Stop unit operation (turn refrigerator off).
2. Holding leak detector exploring tube as close to
system tubing as possible, check all piping, joints,
and fittings.
NOTE: Use soap suds on areas leak detector cannot
reach or reliably test.

Service Procedures
!
WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a 10,000 ohm resistor before attempting
to service. Ensure all ground wires are connected before certifying unit as repaired and/or operational.
3. Visually check system for kinks in refrigeration line
which is causing restriction. Correct kink and repeat
step 2.
Restrictions
Symptoms
Restrictions in sealed system most often occur at
capillary tube or filter drier, but can exist anywhere on
liquid side of system.
4. Turn unit off and time how long it takes high and low
pressure gauges to equalize:
Restrictions reduce refrigerant flow rate and heat
removal rate. Wattage drops because compressor is
not circulating normal amount of refrigerants.
• If pressure equalization takes longer than 10
minutes, a restriction exists in the capillary tube or
drier filter. Go to step 5.
Common causes of total restrictions are moisture,
poorly soldered joints, or solid contaminants. Moisture
freezes at evaporator inlet end of capillary tube. Solid
contaminants collect in filter drier.
• If pressure equalization takes less than 10 minutes,
system is not restricted. Check for other possible
causes of malfunction.
5. Recover refrigerant in sealed system.
If restriction is on low side, suction pressure will be in a
vacuum and head pressure will be near normal.
NOTE: Before opening any refrigeration system,
capture refrigerant in system for safe disposal.
If restriction is on high side, suction pressure will be in
a vacuum and head pressure will be higher than
normal during pump out cycle.
6. Remove power from unit.
! CAUTION
Refrigeration occurs on low pressure side of partial
restriction. There will be a temperature difference at
the point of restriction. Frost and/or condensation will
be present in most case at the point of restriction.
Also, system requires longer to equalize.
To avoid risk of personal injury or property damage,
take necessary precautions against high
temperatures required for brazing.
Slight or partial restriction can give the same
symptoms as refrigerant shortage including lower than
normal back pressure, head pressure, wattage, and
warmer temperatures.
7. Remove and replace restricted device.
8. Evacuate sealed system.
9. Charge system to specification.
Total restriction on the discharge side of compressor,
when restriction is between compressor and first half
of condenser, results in higher than normal head
pressure and wattage while low side is being pumped
out.
NOTE: Do not use captured or recycled refrigerant in
units. Captured or recycled refrigerant voids any
compressor manufacturer's warranty.
NOTE: Charge system with exact amount of refrigerant.
Refer to unit nameplate for correct refrigerant
charge. Inaccurately charged system will cause
future problems.
Testing for Restrictions
To determine if a restriction exists:
1. Attach gauge and manifold between suction and
discharge sides of sealed system.
2. Turn unit on and allow pressure on each side to
stabilize. Inspect condenser side of system. Tubing
on condenser should be warm and temperature
should be equal throughout (no sudden drops at any
point along tubing).
• If temperature of condenser tubing is consistent
throughout, go to step 4.
• If temperature of condenser tubing drops suddenly
at any point, tubing is restricted at point of
temperature drop (if restriction is severe, frost may
form at point of restriction and extend down in
direction of refrigerant flow in system). Go to step 5.

5. After compound gauge (low side) drops to
approximately 29 inches gauge, open valve “C” to
vacuum thermocouple gauge and take micron
reading.
Moisture in sealed system chemically reacts with
refrigerant and oil to form corrosive hydrofluoric and
hydrochloric acids. These acids attack motor windings
and parts, causing premature breakdown.
NOTE: A high vacuum pump can only produce a good
vacuum if oil in pump is not contaminated.
Before opening system, evaporator coil must be at
ambient temperature to minimize moisture infiltration
into system.
6. Continue evacuating system until vacuum gauge
registers 600 microns.
Evacuation
To evacuate sealed refrigeration system:
7. At 600 microns, close valve “A” to vacuum pump and
allow micron reading in system to balance. Micron
level will rise.
1. Connect vacuum pump, vacuum tight manifold set
with high vacuum hoses, thermocouple vacuum
gauge and charging cylinder as shown in illustration.
• If in 2 minutes, micron level stabilizes at 1000
microns or below, system is ready to be charged.
Evacuation should be done through I.D. opening of
tubes not through line piercing valve.
• If micron level rises above 1000 microns and
stabilizes, open valve “A” and continue evacuating.
2. Connect low side line to compressor process tube.
• If micron reading rises rapidly and does not
stabilize, a leak still exists in system.
3. Connect high side line to drier/process tube.
4. Evacuate both simultaneously. With valve “C” and “F”
closed, open all other valves and start vacuum pump.
16022675
High Side Gauge
Close valve “A” to vacuum pump and valve “C” to
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, repair leak, and begin at
step 1.

to service. Ensure all ground wires are connected before certifying unit as repaired and/or operational.
Charging
NOTE: Do not use captured or recycled refrigerant in
units. Captured or recycled refrigerant voids any

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.
NOTE: Do not use refrigerant amount or type other than
shown on serial plate.
NOTE: Charge system with exact amount of refrigerant.
Refer to unit serial plate for correct refrigerant
charge. Inaccurately charged system will cause
future problems.
To charge system:
1. Close valves “A” to vacuum pump and “C” to vacuum
gauge and “E” to low side manifold gauge.
2. Set scale on dial-a-charge cylinder for corresponding
HFC134a pressure reading.
3. Open valve “F” to charging cylinder and let exact
amount of refrigerant flow from cylinder into system.
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.
4. If pressure equalizes, open valve “E” to low side
manifold gauge and pinch off high side drier process
tube.
5. Start compressor and draw remaining refrigerant
from charging hoses and manifold into compressor
through compressor process tube.
6. To check high side pinch-off drier process tube. Close
valve “D” to high side gauge. If high side pressure
rises, repeat high side pinch-off and open valve “D”.
Repeat until high side pinch-off does not leak.
7. Pinch-off compressor process tube and remove
charging hose. Braze stub closed while compressor is
operating.
8. Disconnect power. Remove charging hose and braze
high side drier process tube closed.
9. Recheck for refrigerant leaks.

HFC134a Service Information
! CAUTION
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.
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.
• Ester oils used in HFC134a systems are so
hydroscopic that by the time an inadequate system
performance is detected, oil will be saturated with
moisture.
• 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.
• Care must be taken to minimize moisture 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.
• Drier filter must always be replaced with service drier
filter, part #B2150504.

procedures require power to be connected. Discharge capacitor through a 10,000 ohm resistor before attempting
to service. Ensure all ground wires are connected before certifying unit as repaired and/or operational.
Replacement Service Compressor
Brazing
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.
! CAUTION
To avoid risk of personal injury or property damage,
take necessary precautions against high
temperatures required for brazing.
Satisfactory results require cleanliness, experience,
and use of proper materials and equipment.
Compressor Testing Procedures
Connections to be brazed must be properly sized, free
of rough edges, and clean.
! WARNING
Generally accepted brazing materials are:
• Copper to copper joints: SIL-FOS (alloy of 15
percent silver, 80 percent copper, and 5 percent
phosphorous). Use without flux. Recommended
brazing temperature is approximately 1400°F. Do not
use for copper to steel connection.
• Copper to steel joints: SILVER SOLDER (alloy of 30
percent silver, 38 percent copper, 32 percent zinc).
Use with fluoride based flux. Recommended brazing
temperature is approximately 1200°F.
• Steel to steel joints: SILVER SOLDER (see copper
to steel joints).
• Brass to copper joints: SILVER SOLDER (see
copper to steel joints).
• Brass to steel joints: SILVER SOLDER (see copper
to steel joints).
To avoid death or severe personal injury, never use
oxygen, air or acetylene for pressure testing or
clean out 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.
Refer to Technical Data Sheet “Temperature
Relationship Chart” for operating watts, test points,
and temperature relationship test for unit being tested.
• 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).
• Thermocouple tips should be attached securely to
specified locations.
• Do not test during initial pull down. Allow one off cycle
or balanced temperature condition to occur before
proceeding with testing.
• Refrigerator must operate minimum of 20 minutes
after thermocouples are installed.
• 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.

• Suction tube temperature below ambient. Always
check for separated heat exchanger when suction
temperature is colder than ambient.
Various conditons could indicate an overcharge. For
example, if the cooling coil is not defrosted at regular
intervals, due to a failure of the defrost system, the
refrigerant will "flood out" and cause the suction line to
frost or sweat. The cause of this problem should be
corrected rather than to purge refrigerant from the
sytem. The freezer section operating colder than
necessary (-2 to -1 F. is considered normal temperature)
or continuous running of the compressor may give the
indication of an overcharge.

WATTAGE
VARIATION
FROM
NORMAL
• Rise of food temperature in both compartments. (See
Note 1 below.)
• Long or continuous run time.
• Look for obvious traces of oil that would occur due to a
leak or cracked refrigerant line.
• Lower than normal wattage.
• Compressor will be hot to touch because of the heat
generated by the motor windings from long continuous
running. It will not be as hot as it would be with a full
charge and long run times for some other reason such
as a dirty condenser.
• Depending on the amount of the shortage, the
condenser will not be hot, but closer to room
temperature. The capillary tube will be warmer than
normal from a slight shortage.
• If the leak is on the high side of the system, both
gauges will show lower than normal readings and will
show progressively lower readings as this charge
becomes less. The suction pressure guage will
probably indicate a vacuum.
• If the leak is on the low side of the system the suction
pressure guage will be lower than normal - probably in
a vacuum - and the head pressure gauge will be
higher than normal. It will probably continue to
become higher because air drawn in through the leak
is compressed by the compressor and accumulates in
the high side (condenser) of the system.
16022675
System Diagnosis
• Only partial frosting of evaporator instead of even
frosting of entire coil.
NOTE 1: Usually the first thing that is noticed by the
user is a rise in temperatureof there food.
Although temperatures will rise in both the
freezer section and the fresh food compartment,
the frozen meats and vegetables will not thaw
immediately. The customer doesn't associate
the problem with the freezer section and will first
notice that milk and other food beverages are
not cold enough.
Under some circumstances, a slight shortage of
refrigerant,might cause food in the fresh food
compartment to freeze due to the additional running
time. With a refrigerant leak, however, it always gets
worse and as the refrigerant charge decreases the
temperature will continue to rise.
shortage, discharge the system, replace the drier-filter,
evacuate and recharge with the specified refrigerant
charge. If the unit performs normally three possibilities
exist: 1) refrigerant loss, 2) partially restricted drierfilter, and 3) moisture in system.
If the unit performs as it previously did you may have a
restricted capillary line or condenser or kinked line.
Find the point of restriction and correct it.
A restriction reduces the flow rate of the refrigerant and
consequently reduces the rate of heat removal.
Complete restriction may be caused by moisture, solid
contaminants in the system, or a poorly soldered joint.
Moisture freezes at the evaporator inlet end of the
capillary tube or solid contaminants collect in the drierfilter. The wattage drops because the compressor is not
circulating the usual amount of refrigerant.
Symptoms of a Restriction
As far as pressure readings are concerned, if the
restriction, such as a kinked line or a joint soldered shut
is anywhere on the low side, the suction pressure would
probably be in a vacuum while the head pressure will be
near normal. If the restriction is on the high side, the
suction pressure, again, will probably be in a vacuum
while the head pressure will be higher than normal
during the pump out period described earlier. In either
case, it will take longer than the normal ten minutes or
so for the head pressure to equalize with the low side
after the compressor stops.
Always remember refrigeration (cooling) occurs on the
low pressure side of a partial restriction (obviously a
total restriction will completely stop the circulation of
refrigerant and no cooling will take place).
Symptoms of Air in System
With a shortage of refrigerant the capillary line will not
have a full column of liquid. As a result, there is a
noticeable hissing sound in the evaporator. This should
not be mistaken for the regular refrigerant boiling
sounds that would be considered normal.
Physically feel the refrigeration lines when a restriction
is suspected. The most common place for a restriction
is at the drier-filter or at the capillary tube inlet or outlet.
If the restriction is not total there will be a temperature
difference at the point of restriction, the area on the
evaporator side will be cooler. In many cases frost and/
or condensation will be present. A longer time is
required for the system to equalize.
Any kinked line will cause a restriction so the entire
system should be visually checked.
A slight restriction will give the same indications as a
refrigerant shortage with lower than normal back
pressure, head pressure, and wattage, warmer product
temperatures.
NOTE 2: If a total restriction is on the discharge side of
the compressor, higher than normal head
pressures and wattages would result. This is
true only while the low side is being pumped out
and if the restriction was between the
compressor and the first half of the condenser.

This can result from a low side leak or improper
servicing. If a leak should occur on the low side, the
temperature control would not be satisfied; thus,
continuous running of the compressor would result. The
compressor would eventually pump the low side into a
vacuum drawing air and moisture into the system. Air
and R134A do not mix so the air pressure would be
added to the normal head pressure, resulting in higher
than normal head pressures.
One way to determine if air is in the system is to read
the head pressure gauge with the product off and
evaporator and condenser at the same temperature and
then take the temperature on the condenser outlet tube.
This temperature should be within 3° or 4° F. of what the
Pressure-Temperature Relation chart shows for the
given idle head pressure. If the temperature of the
condenser outlet is considerably lower than the idle
head pressure of the gauge this would indicate there is
air in the system.
Thorough leak checking is necessary. Correct the
source of the leak. Do not attempt to purge off the air
because this could result in the system being
undercharged. It is best to discharge, replace drier,
evacuate and recharge with the specified refrigerant
charge.

System Diagnosis
Symptoms of Low or High Ambient
Temperature Installation
Lower ambient air temperature reduces the condensing
temperature and therefore reduces the temperature of
the liquid entering the evaporator. The increase in
refrigeration effect due to operation in a lower ambient
results in a decrease in power consumption and run
time. At lower ambients there is a reduction in cabinet
heat leak which is partially responsibile for lower power
consumption and run time.
An increase in refrigeration effect cannot be expected
below a certain minimum ambient temperature. This
temperature varies with the type and design of the
product.
Generally speaking, ambient temperatures cannot be
lower than 55° F. without affecting operating efficiency.
Conversely, the higher the ambient temperature the
higher the head pressure must be to raise the high side
refrigerant temperature above that of the condensing
medium. Therefore, head pressure will be higher as the
ambient temperature raises. Refrigerators installed in
ambient temperatures lower than 55° F. will not perform
as well because the pressures within the system are
generally reduced and unbalanced. This means that the
lower head pressure forces less liquid refrigerant
through the capillary line. The result is the symptoms of
a refrigerant shortage. The lower the ambient
temperature the more pronounced this condition
becomes.
When a point where the ambient temperature is below
the cut-in of the Temperature Control is reached, the
compressor won't run.
Heat Load
A greater heat load can result from the addition of more
than normal supply of foods, such as after doing the
weekly shopping. Other items contributing to an
additional heat load would be excessive door openings,
poor door sealing, interior light remaining on, etc.
An increase in heat being absorbed by the refrigerant in
the evaporator will affect the temperature and pressure
of the gas returning to the compressor. Compartment
temperatures, power consumption, discharge, and
suction pressures are all affected by heat load.
Pressures will be higher than normal under heavy heat
load.

Operation
When the thermostat senses temperature of 17 ±3°F
(-8 ±1°C), the thermostat closes. Current now has a
path through the thermostat to the motor (wiring
diagram
P. 41). The motor turns the drive gear. Electrical
contacts protruding from the module brush against
copper strips on the backside of the drive gear
(illustration P. 41). As the drive gear turns, the rotating
copper strips make and/or break connections between
the electrical contacts, controlling icemaker
operations.
Design of the ice maker allows testing of all
components without removing the ice maker or having
to access the water valve.
Remove the cover and you will see test points

Adjustment
Area
Water Fill Adjustment
Turning the water level adjustment screw moves the
contact point in relationship with the contact ring
segment upon which it rides. Because the contact ring
is tapered, movement of the contact point causes
variation in the length of time that the water valve is
energized.
When small hole is centered in larger hole, water
fill time is 7.5 seconds (normal).
Water Problems
Water quality can cause ice makers to fail, to flood, or
produce unacceptable cubes. If mineral content or
sand is a problem, the screen in the fill valve can clog
and restrict water flow. A particle of sand can prevent
the valve from seating properly.
Symptoms of clogging include small crescents (or no
ice). Symptoms of a dirty valve include flooding of the
ice container when the water valve does not close.
Mineral contact can also lime up the mold, causing
• Turning screw clockwise decreases fill time; turning
screw counterclockwise increases fill time.
• One half turn equals 20 cc or 1.2 seconds. A full turn
equals 40 cc or 2.4 seconds.
! CAUTION
Maximum adjustment is one full turn in either direction.
Additional rotation can damage the module.
If water valve adjustment screw falls out, put it back
in and turn it until the holes align as shown below.

Thermal Fuse
Silicone is applied at the upper edges, around fill cup
and stripper.
A one-time thermal fuse, incorporated into the ice
maker wiring harness, protects the plastic liner from
melting if the ice maker overheats. The thermal fuse is
spliced into the red wire of the ice maker harness. It is
a nonresettable fuse, and it is designed to blow at
170°F (78° C).
Temperature Problems
Temperatures in freezer section that average more than
0 ± 2°F (18 ± 1°C) slow the formation of ice. Therefore,
complaints of inadequate ice production can sometimes
be corrected by setting the freezer thermostat to a
colder temperature. Thermostat cycling temperature in
the one-revolution ice maker is 17° ±3°F (-8° ±1°C).
Obviously, the ice will be well frozen when those
temperatures are achieved. But cycling time is slow if
freezer temperature is not cold enough to achieve
those temperatures easily.
Presence of this fuse in the circuit means that a "No
Ice" complaint could be caused by excessive heat.
Where overheating is the problem, replacement of the
wiring harness is a temporary solution. The ice maker
should also be replaced.
Bimetal Thermostat
Follow "Test Procedures" (P. 37) to test operation of the
bimetal thermostat.
NOTE: Replacement thermostats are no longer
available for ice makers. If your thermostat is
faulty, order a new ice maker.

Installation
Your new refrigerator was packed carefully for
shipment. Remove and discard shelf packing and tape.
Location
• Allow for a free flow of air through the front base
grille.
• Install the refrigerator where the room temperature
will not go below 55° F. With temperatures below
55° F, the refrigerator will not run frequently enough
to maintain proper temperature in the freezer.
• Allow a minimum 1⁄2" clearance on the sides, top and
back for ease of installation. If refrigerator is placed
with the door hinge side against a wall, you may
want to allow additional space so the door can be
opened wider.
Front Base Grille
The front base grille was packaged inside the
refrigerator for shipment and should be installed after
the refrigerator has been leveled.
To Install:
• Use a Phillips screwdriver to remove the two Phillips
head screws at the base of the refrigerator.
• Align the base grille to the screw holes. (The cut out
side on the base grille installs around the lower
hinge of the door.)
• Secure the base grille into place by reinstalling the
Phillips screws back into their original screw holes.
• Use caution when installing the unit on vinyl or
hardwood floors so as not to mark or otherwise
damage the flooring. A piece of plywood, a rug or
other material should be used to protect the floor
while positioning the unit.
Leveling
To enhance its appearance and to maintain
performance, your refrigerator should be leveled after it
has been rolled into its final location.
• Adjust the leveling/lock screws beneath each front
corner at the base of the cabinet. Turn these
leveling/lock screws clockwise to raise a cabinet
corner and counterclockwise to lower a cabinet
corner.
Energy Saving Tips
• Locate the refrigerator away from heat producing
appliances such as the range or dishwasher, heat
vents and direct sunlight.
• Level the refrigerator and do not block ventilation
around the front base grille.
• Let hot dishes cool slightly before putting into the
refrigerator or freezer.
• Cover liquids.
• Keep the freezer full to near capacity so less cold air
will escape during door openings. When the freezer
is less than 2⁄3 full, place milk cartons half full of
water in the freezer.
To lower
cabinet
To raise
cabinet
• Wipe moisture from the outside of containers before
placing them into the refrigerator.
• Avoid opening the doors too often.
• If the floor is not level and it is necessary to raise the
rear of the cabinet, we suggest rolling the rear
wheels onto a piece of plywood or other shim
material.

No Defrosting
Your refrigerator is designed to defrost automatically.
Note
Note
• Your refrigerator will run continuously for several
hours when you first start it. This is normal.
• Let the refrigerator run at least four hours before
adding food.
Adjusting the Temperature
Controls
• 24 hours after adding food, you may decide that one
or both compartments should be colder or warmer. If
so, adjust the control(s) as indicated in the following
table.
• Except when starting the refrigerator, do not change
either control more than one number at a time.
• Allow 24 hours for temperatures to stabilize before
resetting.
• Changing either control will have some effect on the
temperature of the other compartment.

Ice Service
Ice Cube Trays
Select models are equipped with ice cube trays. To
release the ice cubes from a tray, hold the tray upside
down over a container and twist both ends.
Automatic Ice Maker (optional)
Note
• Energy rating guides that are posted on the
refrigerator at the time of purchase do not include
optional ice maker energy usage.
Select models are automatic ice maker ready. The
number of the appropriate ice maker kit needed for
installation into these models appears on the data
plate. The kit contains installation instructions and
water connection instructions.
Connect the ice maker to the water supply as
instructed in the separate instructions furnished with
the ice maker. Proper water flow and a level
refrigerator is essential for optimal ice maker
performance.
After your refrigerator has been connected to the water
supply, move the sensor arm into the down position.
The ice maker will fill with water when the freezer
reaches the proper temperature.
Some ice makers are equipped with an adjustable
sensor arm that allows you to adjust the amount of ice
in your ice storage tray for times when less ice is
needed.

Arm
To adjust the amount of ice produced: (select
models) Rotate the wire lever arm to provide the
desired level of ice production. The 100% setting
provides maximum ice production.
• It may be 8 to 12 hours before the ice maker
furnishes any usable ice cubes. The first one or two
batches will probably contain undersized and
irregular cubes because of air in the supply line.
• The initial batch may also contain impurities from the
new water supply piping. Therefore, all cubes from
the first two or three batches should be discarded.
• When the ice cubes are ejected it is normal for
several cubes to be joined together at the ends. They
can easily be broken apart. The ice maker will
continue to make ice until the supply of ice cubes
raises the sensor arm, shutting the ice maker off.
• Certain sounds may accompany the various cycles of
the ice maker. The motor may have a slight hum, the
cubes will rattle as they fall into an empty storage pan
and the water valve may click or “buzz” occasionally.
• If the ice is not used frequently, the ice cubes will
become cloudy, shrink, stick together and taste stale.
Empty the ice storage bin periodically and wash it in
lukewarm water. Be sure to dry the bin before
replacing it.
• To remove the ice bin, pull it forward, away from the
ice maker. To avoid the ice maker dumping ice while
the bin is removed, turn the ice maker off by lifting
the sensor arm.
• To replace the ice bin, reverse the above procedure.
Turn the ice maker on by lowering the sensor arm.
• Beverage and foods should not be placed in the ice
storage bin for quick chilling. These items can block
the sensor arm, causing the ice maker to malfunction.
• Turn off (arm up) the ice maker when the water
supply is to be shut off for several hours.
WARNING
To avoid personal injury or property damage:
• Do not place fingers or hands on the automatic ice
making mechanism while the refrigerator is
plugged in. This will help protect you from possible
injury. It will also prevent interference with moving
parts of the ejector mechanism and the heating
element that releases the cubes.
• Under certain rare circumstances, ice cubes may
be discolored, usually appearing with a greenbluish hue. The cause of this unusual discoloration
can be a combination of factors such as certain
characteristics of local waters, household plumbing
and the accumulation of copper salts in an inactive
water supply line which feeds the ice maker.
Continued consumption of such discolored ice
cubes may be injurious to health. If such
discoloration is observed, discard the ice cubes
and contact your dealer to purchase and install a
water line filter.
• Water damage due to improper water connection
may cause mold/mildew growth.

Food Storage Tips
Fresh Food Storage
Frozen Food Storage
• The fresh food compartment of a refrigerator should
be kept between 34° F and 40° F with an optimum
temperature of 37° F. To check the temperature, place
an appliance thermometer in a glass of water and
place in the center of the refrigerator. Check after
24 hours. If the temperature is above 40° F adjust the
control as explained on page 5.
• The freezer compartment of a refrigerator should be
kept at approximately 0° F. To check the temperature,
place an appliance thermometer between the frozen
packages and check after 24 hours. If the
temperature is above 0° F, adjust the control as
explained on page 5.
• Avoid overcrowding the refrigerator shelves. This
reduces the circulation of air around the food and
results in uneven cooling.
Fruits and Vegetables
• Storage in the crisper drawers traps humidity to help
preserve the fruit and vegetable quality for longer
time periods (see page 6).
• Sort fruits and vegetables before storage and use
bruised or soft items first. Discard those showing
signs of decay.
• Always wrap odorous foods such as onions and
cabbage so the odor does not transfer to other
foods.
• While vegetables need a certain amount of humidity
to remain fresh, too much moisture can shorten
storage times (especially leafy items). Drain
vegetables well before storing.
Meat and Cheese
• Raw meat and poultry should be wrapped securely
so leakage and contamination of other foods or
surfaces does not occur.
• Occasionally mold will develop on the surface of
hard cheeses (Swiss, Cheddar, Parmesan). Cut off at
least an inch around and below the moldy area. Keep
your knife or instrument out of the mold itself.
Do not try to save individual cheese slices, soft cheese,
cottage cheese, cream, sour cream or yogurt when
mold appears.
Dairy Food
• Most dairy foods such as milk, yogurt, sour cream
and cottage cheese have freshness dates on their
cartons for appropriate length of storage. Store these
foods in the original carton and refrigerate
immediately after purchasing and after each use.
9
• A freezer operates more efficiently when it is at least
2
⁄3 full.
Packaging Foods for Freezing
• To minimize dehydration and quality deterioration use
aluminum foil, freezer wrap, freezer bags or airtight
containers. Force as much air out of the packages as
possible and be sure they are tightly sealed. Trapped
air can cause the food to dry out, change color and
develop an off-flavor (freezer burn).
• Overwrap fresh meats and poultry with suitable
freezer wrap prior to freezing.
• Do not refreeze meat that has completely
thawed.
Loading the Freezer
• Avoid adding too much warm food to the freezer at
one time. This overloads the freezer, slows the rate of
freezing and can raise the temperature of frozen
foods.
• Leave a space between the packages so cold air can
circulate freely, allowing food to freeze as quickly as
possible.
• Avoid storing hard-to-freeze foods such as ice cream
and orange juice on the freezer door shelves. These
foods are best stored in the freezer interior where the
temperature varies less with door openings.

Troubleshooting
Normal Operating Sounds
Improvements in refrigeration design may produce sounds in your new refrigerator that are different or were not
present in an older model. These improvements were made to create a refrigerator that is better at preserving food,
is more energy efficient, and is quieter overall. Because new units run quieter, sounds may be detected that were
present in older units, but were masked by higher sound levels. Many of these sounds are normal. Please note that
the surfaces adjacent to a refrigerator, such as hard walls, floors and cabinetry may make these sounds seem even
louder. The following are some of the normal sounds that may be noticed in a new refrigerator.
DEFROST TIMER: Frost-free
refrigerators have a defrost timer
that will generate a clicking
sound when it cycles the unit
into and out of defrost cycle.
ICE MAKER: (if equipped) The ice maker
will occasionally generate a rattling sound
when the ice cubes are ready to drop down
into the ice bin. Also, the motor that ejects
the ice from its tray prior to dropping the
ice may also be detectable. These are
normal sounds necessary for making ice.
DEFROST HEATER: During
the automatic defrost cycle, a
sizzling sound may be heard
as water droplets come into
contact with the defrost
heater. This is a normal
sound heard during defrost.
FREEZER COMPARTMENT
CONTRACTION AND EXPANSION: A popping sound may
occur in the freezer when the
unit starts up due to contraction
or expansion of the materials in
the freezer area.
REFRIGERANT FLOW: The flow of the
refrigerant in your refrigerator may cause a
gurgling or rattling sound when the unit is
running or just after the unit cycles off. The
refrigerant is still flowing in the tubing.
AIRFLOW SOUNDS: Both the freezer
evaporator fan and the condenser fan at the
bottom of the cabinet will create airflow
sounds. The evaporator fan is circulating the
cold air throughout the refrigerator and freezer
compartments. The condenser fan is removing
the heat generated when the unit is cooled.
COMPRESSOR: In order for a new
refrigerator to run more efficiently,
the refrigeration system may run
longer to keep food at the desired
temperatures for freshness. That
new, high efficiency compressor may
run longer and generate sounds such
as a higher pitched hum or pulsation.
WATER VALVE (if equipped): A buzzing
sound may be detected in the back of
the unit when the ice dispenser calls for
the water valve to open to fill the ice
maker tray. Following the ejection of the
ice, there may be some water dripping
sounds when the trays are being filled.
CABINET LEVELING: An unlevel
cabinet may cause rattling or vibrating
noises. This can be fixed by adjusting
the wheels or levelers properly.
