CABINET CONSTRUCTION

Cabinet

The outer case is made of prepainted steel with
a textured finish. The fresh food and freezer
liners are made of plastic with a smooth finish.
Individual compartments provide separation and
enhanced individual control between the
compartments. The plastic liner provides a
thermal break between the interior of the
refrigerator and freezer compartments and
reduces the transfer of heat from the room into
the fresh food and freezer compartments. The
liner is not removable or replaceable.

Base Grille

The base grille is attached to the cabinet with
two steel spring retainers that clip into elongated
openings in the base channel. To remove the
grille, pull it straight forward.

Doors

The doors are of one-piece construction with
foam insulation. One-piece construction
provides superior thermal performance and
reduces air infiltration. During manufacturing,
the doors are filled with hot foam insulation.
This may cause slight distortion or ripples in the
inner door liner. This is a normal condition and
is the result of the insulating process. This
process requires doors to be equipped with vent
holes that allow air to escape when the door is
filled with foam. A small amount of foam may be
visible around the vent holes.

The inner door panels and outer door panels
cannot be separated and must be replaced as
an assembly.

Door Gaskets

The fresh food and freezer doors have magnetic
gaskets that create a positive seal to the front of
the steel cabinet. The magnetic door gaskets
are secured to the fresh food and freezer doors
by a barbed edge that locks into a retainer
channel.

1. Starting at any corner, pull the old gasket out
of the retainer channel.

2. Soak the new gasket in warm water to make
it pliable.

3. Push the barbed edge of the gasket into the
retainer channel.

Rollers

Rollers at the base of the cabinet enable the
customer to easily move the refrigerator.
Cabinet leveling is done by adjusting the front
rollers. To adjust the front rollers, use a 3/8-in.
socket or a large flat head screwdriver to turn
the roller adjustment screws located behind the
base grille. The rear rollers are not adjustable.

To remove a front roller assembly from the base
of the cabinet:

1. Tilt the cabinet back and place a
3-in. block under the side of the unit.

2. Remove 3 hex head 1/4-in. screws from the
roller assembly.

3. Loosen the adjustment screw until it
disengages from the assembly and remove
the assembly from the cabinet.

4. Remove the E-ring to remove the
adjustment screw from the base channel.

Note: When reinstalling the roller assembly,
position the nut with the flared thread toward the
rear of the unit.

AIRFLOW

Freezer Compartment

Cold air from the evaporator is forced up against
the top of the freezer and the back of the
evaporator cover. It is then discharged through
slots along the air tower at the rear of the
freezer compartment.

Air is circulated by the evaporator fan
throughout the freezer compartment, where it
picks up heat and moisture. The evaporator fan
then draws the warmer, moisture-laden air
through return louvers in the bottom of the
evaporator cover. The air is then drawn through
the evaporator where heat is removed and
moisture is deposited as frost.

Fresh Food Compartment

Some of the cold air that is being forced against
the top of the freezer and back of the evaporator
cover is diverted through the lower portion of the
freezer air tower and is pushed though the
mullion hole into the fresh food compartment air
channel. The air then exits the air channel in the
front of the fresh food compartment, creating a
curtain of cold air along the front of the shelves.
The fresh food air channel also has a rear
discharge to maintain deli drawer temperatures.

Air circulates throughout the fresh food
compartment, picking up heat and moisture.
The air is then returned to the evaporator
through the return air ducts located at the top
right and left of the fresh food compartment.

Note: These refrigerators do NOT use damper
assemblies to regulate the flow of air to the
fresh food compartment. Airflow is regulated by
a three-speed evaporator fan and a sized air
duct system that provide predictable, consistent
air exchange rates for each level of fan speed.

Condenser Fan

The condenser fan utilizes a DC motor that
operates on a single speed and is mounted in
the machine compartment with the No-Clean
condenser. The fan and fan shroud are
mounted on one end of the condenser, the other
end of the condenser is blocked. When the fan
is operating, air is pulled from the center of the
condenser, drawing air in through the coils. The
air is then exhausted over the compressor and
out the right side of the refrigerator.

Inlet air is available through the left front and left
rear of the machine compartment. A rubber
divider strip underneath the refrigerator divides
the inlet and outlet sides of the machine
compartment.

The rear access cover must be tightly fitted to
prevent air from being exhausted directly out of
the rear of the machine compartment, bypassing
the compressor.

The condenser fan is mounted with screws to a
fan shroud and mounting bracket that is
attached to the condenser. To remove the fan:

DEFROST SYSTEM

Adaptive Defrost

Adaptive Defrost can be described as a defrost
system that adapts to a refrigerator’s
surrounding environment and household usage.

Unlike conventional defrost systems that use
electromechanical timers with a fixed defrost
cycle time, Adaptive Defrost utilizes an
intelligent, electronic control to determine when
the defrost cycle is necessary. In order to
accomplish the correct defrost cycle time, the
main control board monitors the following
refrigerator operations:

• Length of time the refrigerator doors were
open since the last defrost cycle

• Length of time the compressor has run
since the last defrost cycle

• Amount of time the defrost heaters were on
in the last defrost cycle

Adaptive Defrost is divided into 5 separate
cycles. Those operations are:

• Cooling Operation

• Pre-Chill Operation

• Defrost Heater Operation

• Dwell Period

• Post Dwell

Adaptive Defrost (Cooling Operation)

During the cooling operation, the main control
board monitors door opening (fresh food and
freezer doors) and compressor run times. The
board counts the time the doors are open. It
reduces the length between defrosts by 210
seconds (multiplication factor) for each second
that each door is open (if both doors are open,
it reduces it by twice the amount). The
multiplication factor reduces compressor run
time. If the doors are not opened, the
compressor will run up to 60 hours between
When the main control board determines that
defrost is necessary, it will force the
refrigerator into a continuous cool mode (pre-

defrosts. If the doors are opened frequently
and/or for long periods of time, the compressor
run time between defrosts will be reduced to as
little as 8 hours.

chill). During pre-chill, the freezer temperature
may be driven below the set point. However,
the fresh food temperature will be regulated by
the evaporator fan running at low speed. Pre­chill will last for 2 hours. These models do not
have a defrost holdoff.

Adaptive Defrost (Defrost Heater
Operation)

After 2 hours of pre-chill operation, the main
control board turns off the compressor,
condenser fan, and evaporator fan.

During defrost operation, the main control board
monitors the evaporator temperature using
evaporator thermistor inputs. Typically, the
evaporator thermistor will sense a temperature
of 65°F within 25 minutes. When the thermistor
senses 65°F, the main control board will
terminate defrost heater operation. Maximum
defrost cycle (heater on) time is 45 minutes
(main control board time out).

The defrost system is protected by a defrost
termination thermostat (switch). The thermostat
opens when the evaporator temperature raises
to 140°F and closes when the evaporator
temperature lowers to 110°F.

– 29 –

Adaptive Defrost (Dwell Period)

After defrost heater operation has been
terminated by the main control board, a 5­minute dwell period occurs. During this period,
the compressor, condenser fan, and the
evaporator fan remain off. The remaining frost
melting from the evaporator will continue to drip
and drain so that prior to the cooling operation,
the evaporator will be totally clear of any
moisture. After the 5-minute dwell period, the
unit goes into post dwell.

Adaptive Defrost (Post Dwell)

The post dwell period is designed to cool the
evaporator before circulating air within the
refrigerator. This prevents any residual heat on
the evaporator from being distributed in the
freezer. During this period, the compressor is on
and the condenser fan is on, but the evaporator
fan is off. Post dwell will last 15 minutes or until
the evaporator temperature reaches 30°F on
these models.

Normal Operating Characteristics That
Are Different from Previous Models

• Evaporator fan running without compressor
or condenser fan.

• Post Dwell (Adaptive Defrost), compressor,
and condenser fan on with evaporator fan off
after defrost cycle.

• Liner Protection Mode, fan comes on when
the doors are open for 3 minutes.

• Evaporator fan and compressor can run
continuously for 2 hours (Adaptive Defrost).

• Different sound levels can be heard when
the fan changes speed.

• Response time for drastic temperature
change is 2 to 10 minutes. The main control
board will only respond to 8 degrees
(Fahrenheit) of temperature change per
minute as determined by resistance of
sensor.

Abnormal Operating Characteristics
(Incorrect Operation)

• Rapid fan speed changes, fan takes at least
1 minute to change speeds.

• Compressor running without the condenser
fan. The compressor and condenser fan
should always run at the same time.

Liner Protection Mode

The liner protection mode will activate if either of
the doors have been open for 3 minutes. This
mode will start the evaporator fan on high
speed.

This mode is controlled by 2 timers. Timer 1
monitors door-open time. A 3-minute door-open
count begins when the door is opened. If 3
minutes elapse before the door is closed, the
liner protection mode will become active. Once
the door is closed, timer 1 resets and liner
protection mode goes into standby. In standby,
normal fan and damper operations resume and
timer 2 begins a 3-minute door-closed count. If
3 minutes elapse without a door opening, liner
protection mode will completely deactivate. If a
door is opened within the timer 2 door-closed
count, the remaining time in the door-closed
count will be deducted from the timer 1 door­open count.

– 30 –

Defrost Heater

The defrost heater is a single-tube, radiant
heater. It is held in place by 2 tabs on the
evaporator (1 on each side) and by 2 ceramic
and wire supports.

The ceramic and wire supports prevent the
heater from sagging and touching the metal
drain pan if the glass is broken.

Evaporator Thermistor

The evaporator thermistor is mounted on the
upper right side of the evaporator. The defrost
cycle will terminate when the main control board
detects 65°F from the evaporator thermistor.
The main control board must sense 65°F in less
than 45 minutes, or the defrost cycle will time
out. Normal defrost time is 25 minutes or less,
not including the 5-minute dwell or post dwell
periods.

Defrost Overtemperature Thermostat

The defrost overtemperature thermostat
(bimetal switch) is mounted on the evaporator
and provides overtemperature protection during
defrost. This thermostat will open at 140°F and
will close at 110°F.

Note: The main control board will not know if
the heater does not come on due to a broken
heater, open defrost overtemperature
thermostat, or an open wiring harness. The
defrost heater is controlled by maximum time on
the main control board or temperature at the
evaporator thermistor.

CONTROL SYSTEM

Control Console

The control console, located at the top front of
the fresh food compartment, contains an
encoder (knob version) or a touch panel.

Remove the control console by removing 4 (1/4­in.) hex head screws. Use care when
disconnecting the wire connectors from the
encoder or touch panel.

Temperature Encoder

The temperature encoder (knob version)
receives switched DC voltage from the main
control board. There are two possible failure
modes - both are open circuits.

An open circuit from the supply side results in
the refrigerator defaulting to midpoint. The
supply side consists of pins 1 and 2.

An open circuit from the return side results in
inconsistent run mode. The return side consists
of pins 3 and 6.

Failure of the fresh-food-only side results in the
fresh food defaulting to midpoint.

Failure of the freezer side results in the freezer
defaulting to midpoint.

Temperature Touch Panel

The temperature touch panel receives switched
DC voltage from the main control board.

Failure of input results in default to most recent
setting. Input consists of pins 2 to 3.

Failure of output results in erratic control.
Output consists of pin 1.

REFRIGERATION SYSTEM

The major components of the refrigeration
system are a reciprocating-type compressor,
condenser, condenser loop, dryer, and a spine­fin evaporator. These components, except for
the condenser loop, are all replaceable
separately.

Compressor

The compressor is a reciprocating type. Refer
to the mini-manual for the BTU/hour rating and
the compressor capacity test specification.
A 1/4-in. O.D. copper process tube is provided
for access to the low-pressure side of the
refrigeration system.

The channel that the compressor is mounted in
must be disengaged from the cabinet to remove
the compressor.

Note:

Capillary tube must be clipped to
compressor suction line near the dryer. If
capillary tube is not clipped to suction line, a
knocking noise may occur during compressor
operation.

Refer to the compressor replacement
instructions included with the replacement
compressor.

No-Clean Condenser

The Condenser is a
condenser made of 3/16-in. O.D. steel tubing.
The outlet of the condenser is connected to a
copper jumper tube that is connected to the inlet
of the condenser loop. The No-Clean
condenser is accessed from the rear of the
cabinet and is designed to be more tolerant of
lint buildup than previous condensers. The
consumer, in normal operating conditions, will
never have to clean the condenser. If
necessary, only an ordinary appliance brush is
used. Air is drawn in from the outside diameter
of the condenser. A condenser fan baffle is
located at the rear to direct airflow through the
condenser. Functionally, the condenser does
the same job as previous models. Air is drawn
into the condenser from the front left and rear
left of the cabinet. Air exits only from the right
side of the cabinet.

No-Clean,

“jelly roll” style

Condenser Loop

The condenser loop, made of 5/32-in. O.D.
copper tubing, is foamed in place behind the
breaker frame and across the mullion. It is not
accessible for replacement. The tubing is
routed from the rear of the machine
compartment forward to the mullion, across the
mullion, across the right side of the freezer
compartment, across the top of the freezer
compartment, down the right side of the freezer,
and back to the rear of the machine
compartment. The outlet of the condenser loop
is connected to the dryer inlet.

Dryer

The dryer is positioned vertically in the center of
the machine compartment. A 1/4-in. O.D.
copper process tube, connected to the inlet of
the dryer, provides access to the high-pressure
side of the refrigeration system. The capillary is
connected to the outlet of the dryer.
Replacement of filter dryer requires additional
refrigerant when installed (0.5 oz).

Note:

The dryer is wrapped in mastic as a
sound reducer and foam tape for shipping
purposes. When replacing the dryer, the mastic
must be reinstalled to reduce sound. It is not
necessary to reinstall the foam tape.

Evaporator

The spine-fin evaporator, made of aluminum
tubing and formed into hairpin spirals, is located
below the evaporator fan housing at the back of
the freezer compartment. The replacement
evaporator is furnished without a heat
exchange.
