Product Design Defrost Controls
Electromechanical
After every 8 hours of compressor run time, a defrost
timer activates the radiant electric defrost heater that is
suspended from the evaporator. After 33 minutes of
defrost time, the timer restores power to the
compressor.
A defrost terminator (thermostat) is wired in series with
the defrost heater and evaporator fan motor. The
terminator opens the defrost circuit when the
temperature of the evaporator reaches a preset high
temperature. When the defrost thermostat opens, it
remains open until the end of the defrost cycle. When
the cooling cycle starts, the terminator senses a preset
low temperature in the evaporator chamber and closes.
The defrost heater is suspended across the bottom of
the evaporator coil so it warms the defrost drain as it
defrosts the evaporator. Defrost water is caught in the
trough under the evaporator coil and flows through a
drain hole and drain tubing, into the drain pan under the
cabinet. Heated air circulated by condenser fan over
drain pan evaporates water.
Electronic
See “Electronic Controls”.
Other Features
Deli DrawerTM
The Deli DrawerTM is a drawer that is mounted in an
extra-cold sleeve within the fresh-food compartment. A
control on the inner wall of the fresh-food compartment
allows freezer air to circulate inside the sleeve, keeping
temperature in the drawer up to 5°F colder than the
fresh-food compartment.
NOTE: Vinyl boot directs freezer air from inlet port to
deli drawer sleeve. Boot must be in place and in
good condition if deli drawer is to work properly.
Beverage Chiller
A control on the left, inner wall of the fresh food
compartment allows freezer air to circulate into
beverage chiller, keeping temperature inside the chiller
up to 4°F colder than the fresh food compartment.
NOTE: Fresh food compartment temperature can be
affected by cold air in beverage chiller and deli
drawer. Refrigerator temperature control may
need adjustment after temperature of deli
drawer or beverage chiller is set.
Refrigeration System
A compressor forces hot refrigerant vapor into a fan
cooled condenser made of aluminum tubing and wire.
Air circulated across the condenser cools and
condenses hot vapor into high-pressure liquid (See
Refrigerant Flow Diagram).
From the condenser, liquid refrigerant passes through a
molecular-sieve drier and into a capillary tube. The small
inside diameter of the capillary offers resistance to
refrigerant flow. The resistance increases pressure on
liquid in the capillary and causes relatively lower
pressure inside the evaporator. The difference in
pressure improves evaporation.
Also inside the capillary, temperature of the liquid
refrigerant is reduced because the capillary is routed
through a heat exchanger. In the heat exchanger, hot
refrigerant in the capillary is cooled by refrigerant vapor
of relatively low temperature that flows through the
suction line. The length of the capillary and heat
exchanger are carefully designed for each system.
The evaporator coil is made of aluminum tubing and
sheet metal. The capillary enters the evaporator at top
rear. Refrigerant in the form of liquid and gas flows
through the coil and into the suction line.
The evaporator coil is inside the back wall of the freezer
compartment. There an evaporator fan circulates air
from the freezer and fresh-food compartments, through
the evaporator coil and out, again, into the freezer and
fresh-food compartments.
The large surface area of the evaporator coil facilitates
heat absorption from both fresh-food and freezer
compartments. Temperature of the evaporator at the
end of the cooling cycle varies from -13° to -26°F.
Temperature Controls
Electromechanical
Freezer compartment temperature is regulated by
means of an air-sensing thermostat located at top rear
of the fresh-food compartment. The thermostat senses
freezer compartment temperature by means of a control
capillary that is routed from the thermostat, through a
well, and into the freezer compartment. The thermostat
control should be set to maintain freezer temperature
between 0° and +2°F.
Fresh-food compartment temperature is also
thermostatically controlled. In this case, an air-sensing
thermostat regulates a damper which controls the
amount of cold air that flows into the refrigerator from
the freezer. Fresh-food compartment temperature
should be kept between 38° and 40°F.
Electronic
See “Electronic Controls”.

Component Testing
!WARNING
To avoid risk of electrical shock, severe personal injury or death; disconnect power to unit before servicing,
unless testing requires power. Discharge capacitor through a 10,000 ohm resistor before handling.
RS1300004 Rev. 1 6
Component Description Test Procedure
Capacitor
Run capacitor connects to relay terminal 3
and L side of line.
Auger motor capacitor is in series with auger
motor. Auger motor capacitor does not have
identified terminals and can be wired without
regard to polarity.
1. Disconnect power to refrigerator.
2. Remove capacitor cover and disconnect capacitor wires.
3. Discharge capacitor by shorting across terminals with a resistor for 1
minute.
4. Check resistance across capacitor terminals with ohmmeter set on
“X1K” scale.
• Good — needle swings to 0 ohms and slowly moves back to infinity.
• 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).
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.
Restricted or clogged capillary tube must be replaced with tube of same
inner diameter and length.
Follow all procedures for evacuation and charging of sealed system and for
safe handling of refrigerant.
Timer, defrost
Timer motor operates only when freezer
temperature control is closed. After specified
amount of actual compressor run time, cam in
timer throws the contacts from terminal 4
(compressor circuit) to terminal 2 (defrost
terminator and defrost heater).
After 33 minutes of defrost time, timer cam
restores power to terminal 4 (compressor).
1. To check timer-motor winding, look for continuity between terminals 1
and 3 of timer.
2. Depending on position of cam, timer terminal 1 is common to terminal
2, (defrost mode) or terminal 4 (compressor mode). There must be no
continuity between terminals 2 and 4.
3. With continuity between terminals 1 and 4, rotate timer knob clockwise
until audible click is heard. When click is heard, reading between
terminals 1 and 4 should be infinite and there should be continuity
between terminals 1 and 2.
4. Rotate timer knob until second click is heard. This should restore circuit
between terminals 1 and 4.
Valve, water Controls water flow to icemaker and cavity. Check resistance across coil windings.
Damper Control
Damper control balances cold-air delivery
between refrigerator and freezer
compartments.
In non-electronic units, integral capillary
activates damper control to close or open
door, regulating airflow from freezer
compartment into fresh-food compartment.
In electronic units, temperature control and
thermistor together determine if damper-
control heater switch is open or closed.
Damper controls on non-electronic units have
no electrical connections.
Subject capillary to appropriate temperature (see tech sheet for model being
serviced). Damper door should close to within ¼” (6 mm) of completely shut.
Non-electronic units: If altitude adjustment is required, turn altitude
adjustment screw 1/8 turn clockwise for each 1,000 feet (305 meters)
increase in altitude above sea-level.

Component Testing
!WARNING
To avoid risk of electrical shock, severe personal injury or death; disconnect power to unit before servicing,
unless testing requires power. Discharge capacitor through a 10,000 ohm resistor before handling.

Control, freezer
temperature
(Non-electronic
units)
F
reezer temperature control is a capillary tub
e
operating a single-pole, single-throw switch. Check control calibration with thermocouple capillary correctly located in air- supply well. Perform check by recording cut-in and cut-out temperatures wit
h
control in middle setting (tech sheet for model being serviced has correct
cut-in/cut-out temperatures).
Check operation of control contacts by disconnecting electrical leads to
control. Then turn control knob to coldest setting and check for continuity
across terminals.
Altitude Adjustment:
In most cases altitude adjustment can be avoided by turning temperature
control to a colder setting. When altitude adjustment is required, turn
adjustment screw 1/7-turn clockwise for each 1,000 feet (305 M) above sea
level, up to 10,000 feet (3050 M).
Condenser Condenser is tube-and-wire construction and
is located in compressor compartment, on
high-pressure side of compressor. Condenser
transfers heat from refrigerant to atmosphere.
Hot, high-pressure gas is routed to condenser
where, as gas becomes relatively cooler, it
condenses into high-pressure liquid. Heat
transfer takes place because refrigerant gas
i
s warmer than air blown across condenser b
y
the condenser fan.
Proper airflow over condenser is important. If
efficiency of heat transfer from condenser to
atmosphere is impaired, temperature of liquid
refrigerant grows higher. Hotter liquid
refrigerant, when it boils in the evaporator,
absorbs less heat than relatively cooler
refrigerant.
Higher than normal head pressures, long run
times, and high energy use together indicate
a dirty condenser. Normal airflow across a
condenser prevents such problems. Remove
lint, dust and other debris from condenser
whenever you service a refrigerator.
From the condenser, refrigerant flows into a
post-condenser loop. Then it moves through
drier and evaporator and back to the
compressor through the suction line. The loop
controls condensation on flange, center
mullion, and around freezer door.
Leaks in condenser can usually be detected by using an electronic leak
detector or soap solution.
B
ecause a small amount of compressor oil always circulates with refrigeran
t,
the presence of oil on condenser also indicates a leak.
Leaks in post-condenser loop are rare because loop is a one-piece copper
tube.
For minute leaks:
1. Separate condenser from rest of refrigeration system and pressurize
condenser up to a maximum of 16 bars (235 PSI) with a refrigerant and
dry-nitrogen mixture.
2. Recheck for leaks and/or watch for pressure drop.
WARNING
!
To avoid risk of severe personal injury or death, observe the following
statements:
1. If high pressures are required for leak checking, protect against
sudden eruptions.
2. Do not use high pressure gases in refrigeration systems without a
reliable pressure regulator and pressure relief valve in the lines.

Component Testing
!WARNING
To avoid risk of electrical shock, severe personal injury or death; disconnect power to unit before servicing,
unless testing requires power. Discharge capacitor through a 10,000 ohm resistor before handling.
RS1300004 Rev. 1 8
Drier Drier is located in machine compartment at
outlet of post-condenser loop. It removes
moisture from liquid refrigerant while passing
refrigerant to capillary.
Drier must be replaced when system is opened for any reason. Before
opening system, recover refrigerant for safe disposal.
Do not debraze drier. Applying heat to remove drier drives moisture out of
drier into system. Cut drier out of system using the following procedure:
1. Score capillary tube close to drier and break.
2. Reform tubes so you have space in which to use a large tubing cutter
on the drier.
3. Cut circumference of drier 1-1/4” (3 cm) below point at which
condenser inlet tube joins drier. Remove drier, leaving only its top
brazed to tubing.
WARNING
!
To avoid risk of severe personal injury or death; cut drier at correct
location. Cutting drier in wrong place allows desiccant beads to
scatter, creating a fall hazard. Clean up beads if spilled.
4. Apply heat-trap paste on post-condenser tubes above drier to protect
grommets from high heat.
5. Debraze remaining part of drier and remove it from system.
6. Discard drier in safe place. Do not leave drier with customer.
7. If unit is in warranty, old drier accompanies warranty claim.
Evaporator Inner volume of evaporator allows liquid
refrigerant to expand into refrigerant gas.
Expansion cools evaporator,
transferring heat from freezer to refrigerant.
Passing through heat exchanger on its way to
compressor, refrigerant gas picks up
superheat from liquid refrigerant. Exchange
assures complete vaporization of liquid
refrigerant inside evaporator.
Compressor pulls refrigerant gas through
suction line to complete cycle.
Use electronic leak detector or solution of soap and water to check for leaks
from evaporator. Presence of oil on evaporator also indicates a leak
because some compressor oil always circulates with refrigerant.
For minute leaks:
1. Separate evaporator from rest of system and pressurize condenser up
to a maximum of 10 bars (140 PSI) with a refrigerant and dry nitrogen
combination.
2. Recheck for leaks and/or watch for pressure drop.
Heater, cavity Applied to back of ice and water cavity to
prevent condensation on face of cavity. Some models have spare heater foamed in place at factory. See tech sheet for model being serviced.
Check resistance across heater (for resistance values see tech sheet for
model being serviced).
Heater, evaporator

Check resistance across heater.
To check defrost system:
1. Thermocouple defrost thermostat and plug refrigerator into wattmeter.
2. Force unit into defrost mode (see “Electronic Testing”). Wattmeter
should read according to tech sheet.
3. When thermostat reaches specified temperature (see tech sheet), it
should interrupt power to heater.
Motor, auger
Located behind ice bucket. Drives helix auger
and cube crusher.
PSC (Permanent Split Capacitor) motor
requiring a run capacitor.
Controlled by ice-actuator switch in series
with freezer-door auger-interlock switch and
cube/crushed ice switch.
Internal overload trips after about 90 seconds
of continuous run. Resets in about 3 minutes.
Disconnect power, check windings with ohmmeter and verify ground.
Crushed/Cube Dispensing Models:
With unit at room temperature, check resistance between wire leads
(see tech sheet for your model).
Cube Dispensing Models:
With unit at room temperature, check resistance between wire leads
(see tech sheet for your model).

condenser coil and compressor body.
Condenser-fan motor wired parallel with
compressor.
Check resistance across winding (for resistance value see tech sheet for
model being serviced).
Motor, evaporator
fan Evaporator motor moves air across evaporator coil and throughout refrigerator.
Evaporator fan is wired in series with
temperature control, defrost terminator, and
defrost heater.
1. Disconnect power to unit.
2. Disconnect fan motor leads.
3. Check resistance from earth connection solder. Trace to motor frame
must not exceed .05 ohms.
4. Check for voltage at connector to motor with terminator and
temperature control closed.
Overload Overload is a temperature and current
sensing device.
Overload opens when high current or high
compressor temperature is sensed.
If overload opens, reset can require up to two
hours, depending on ambient temperature,
ventilation, and heat of compressor.
Relay (See PTC Relay)
1. Disconnect power to the refrigerator.
2. Remove relay cover and pull relay off compressor. Pull overload
protector off compressor common terminal.
3. With ohmmeter, check resistance between male terminal and female
receptacle of compressor common terminal. At room temperature,
overload protector should have less than 1 ohm resistance. An open
overload protector will have infinite resistance.
Relay, PTC
When voltage is connected and relay is cool,
current passes through relay to start winding.
After a short time, current heats resistor in
relay. Resistance rises, blocking current flow
through relay. Start winding remains in circuit
through run capacitor.
Relay plugs directly onto compressor START
and RUN terminals. Relay terminals 2 and 3
are connected within relay. Run capacitor is
connected to relay terminal 3. L2 side of 120
VAC power is connected to relay terminal 2.
With power off, check resistance across terminals 2 and 3:
