Introduction

2001 Energy SxS models are being introduced in
response to the requirement for more energy­efficient refrigerators by mid year 2001, along with
having feature and oper ation enhancements . The
primary differences in this refrigeration system are
the adaptive defrost system (see Pub. # 31-9062),
control board, software, and control systems that
operate independently in fresh food and freezer
sections. The new high-efficiency control system
has the ability to cycle components and adjust fan
speeds as required to maintain temperature­setting ranges in freezer and fresh food sections.
Feedback systems are digital inputs and relay
outputs. Sensors (thermistors) are used to
measure temperature with communications to a
main PC board, which controls the unit
components. The refrigerator has versions that
have control knobs or touchpads (Profile models)
to provide inputs to a microprocessor. The freezer/
fresh food controls are temperature setpoint type
and have settings of 0-9 with 9 being the coldest
temperature possible. The new NO CLEAN
condenser is serviceable from the rear and is
designed to prevent the customer from having to
clean the condenser in normal usage conditions.

The freezer has adjustable shelves, slide-out
Spillproof shelf, QuickSpace shelf, and deep door
shelves, based on model. The fresh food section
has a baking soda holder , fruit and vegetab le
drawer, drawer dividers, adjustable humidity
drawer, and convertible meat drawer.

This new high-efficiency refrigerator is a
combination of the most efficient refrigeration
system and the most desirable customer features
available.

Sealed system operation and compressor are
functionally the same as previous models, with
some minor changes.

The 20', 22', and 25' side-by-side models are the
models affected. These models are available with
through-the-door chilled water and ice dispenser ,
and built-in water filter feature. On models
requiring icemaker, the newest electronic
icemaker (see Pub. # 31-9063) has been or can
be installed.

Installation

ATTENTION INSTALLER:

FOR A QUALITY INSTALLATION,
FOLLOW THESE INSTRUCTIONS.

• REMOVE AND DISCARD
SKIDBOARDS and bolts used to
hold skidboards.

• Use PADDED HAND TRUCK
to protect refrigerator finish.

• LEAVE TAPE ON DOORS until
refrigerator is in its final location.

• ADJUST FRONT ROLLERS
so that refrigerator is solid and
doors close easily.

• MAKE SURE DOORS ARE EVEN
AT TOP. Check gasket seal.

• SET BOTH CONTROLS TO “5”.

• SET ICEMAKER TO OFF until
water line is connected.

• IMPORTANT: IMMEDIATELY REMOVE ALL CLEAR PROTECTIVE TAPE FROM TRIM.

• TO REMOVE TAPE RESIDUE AND HANDPRINTS, USE APPLIANCE POLISH.

• REMOVE ALL TAPE AND OTHER PACKAGING MATERIAL FROM INSIDE REFRIGERATOR. DO NOTREMOVE SERIAL PLATE.

IMPORTANT: PLEASE READ CAREFULLY

FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED.

The power cord of this appliance is equipped with a three-prong (grounding) plug that mates with a standard three-prong (grounding) wall receptacle to minimize the
risk of electric shock hazard from this appliance. The customer should have the wall receptacle and circuit checked by a qualified electrician to make sure the receptacle
is properly grounded.

Where a standard two-prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to have it replaced with a properly grounded
three-prong wall receptacle.

DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE THIRD (GROUND) PRONG FROM THE POWER CORD.
USAGE

SITUATIONS WHERE THE APPLIANCE’S POWER CORD WILL BE DISCONNECTED INFREQUENTLY

Because of potential safety hazards under certain conditions, we strongly recommend against the use of an adapter plug. However, if you still elect to use an adapter,
where local codes permit, a TEMPORARY CONNECTION may be made to a properly grounded two-prong wall receptacle by the use of a UL listed adapter which is
available at most hardware stores. The larger slot of the adapter must be aligned to provide proper polarity in the connection of the power cord.

CAUTION: Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal, and not insulated,
and the wall receptacle is grounded through the house wiring. The customer should have the circuit checked by a qualified electrician to make sure the receptacle is
properly grounded. When disconnecting the power cord from the adapter, always hold the adapter with one hand. If this is not done, the adapter ground terminal is very
likely to break with repeated use. Should this happen, DO NOT USE the appliance until a proper ground has again been established.

USAGE

SITUATIONS WHERE THE APPLIANCE’S POWER CORD WILL BE DISCONNECTED FREQUENTLY

Do not use an adapter plug in these situations because frequent disconnecting of the power cord places undue strain on the adapter and leads to eventual failure of the
adapter ground terminal. The customer should have the two-prong wall receptacle replaced with a three-prong (grounding) receptacle by a qualified electrician before
using the appliance.

Normal Operating Characteristics That Are
Different from Previous Models

• Length of time the compressor has run since

the last defrost cycle.

Icemaker auger rotates clockwise.

•

• 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 (F ahrenheit) of
temperature change per minute as determined
by resistance of sensor.

Abnormal Operating Characteristics
(Incorrect Operation)

• Evaporator fan on, compressor off, and

damper shut (except liner protection mode).

• 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.

• 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

(See Pub. #31-9062 for more information on

Adaptive Defrost.)

Cooling Operation (Adaptive Defrost)

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 255
seconds (multiplication factor) for each second
that each door is open. If both doors are open, it
reduces it by twice the amount. The m ultiplication
factor reduces compressor run time. If the doors
are not opened, the compressor will run up to 60
hours between 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.

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.

into a continuous cool mode (pre-chill). During pre­chill, the freezer temperature may be driven below
the set point. However, the fresh food temperature
will be regulated by the damper. Pre-chill will last
for 2 hours. These models do not have a defrost
holdoff.

Defrost Heater Operation (Adaptive
Defrost)

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. The thermistor will
terminate defrost heater operation in less than 45
minutes. Typical defrost time is 20-30 minutes.
Maximum defrost cycle is 45 minutes with heater
on, 5 minutes in dwell.

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 and close the
damper.

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, nor mal 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 door-open count.

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

Dwell Period (Adaptive Defrost)

After defrost heater operation has been terminated
by the main control board, a 5-minute 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.

Post Dwell (Adaptive Defr ost)

The post dwell period is designed to cool the
evaporator before circulating air within the
refrigerator. This prevents any residual heat on the
ev aporator from being distrib uted in the freezer.
During this period, the compressor is on and the
condenser fan is on, but the evaporator fan is off,
and the damper is closed. Post dwell lasts 10
minutes on these models.

Dispensing Functions

The water, crushed ice, and cubed ice functions
are controlled by the main control board. To select
a function, press the appropriate pad on the
dispenser. The LED will light to identify the
selection.

To dispense the selected item, depress the
dispenser cradle located in the dispenser recess.
The solenoid and linkage assembly will open the
ice chute door to dispense the ice. If cubed ice is
selected, the crushed ice bypass solenoid will
allow cubed ice to bypass the ice crusher. The ice
chute door must remain open for 5 second after
dispensing ceases. After this 5 second delay, the
solenoid and linkage assembly will shut the ice
chute door.

The dispenser light will come on automatically
when the dispenser cradle is depressed and will
fade out 5 seconds after it is released.

Dispenser Light

The LIGHT pad turns the dispenser light on and
off. When the light is turned off, it will fade out. The
dispenser light will come on automatically when
the dispenser cradle is depressed and will fade
out 5 seconds after it is released. The LIGHT pad
will not turn off the light during dispense.

– 9 –

Dispenser Lock

When the dispenser system is locked, no
dispenser command will be accepted. This
includes the dispenser cradle and will prevent
accidental dispensing that may be caused by
children or pets. If a pad is pressed with the
system locked, it will be acknowledged with 3
pulses of the LOCK LED accompanied by an
audible tone.

To lock or unlock communication between the
dispenser and main control board, press the
LOCK pad and hold it for 3 seconds. The LOCK
LED will flash while the LOCK pad is pressed.
When the communication is locked, the LOCK
LED will be illuminated.

The status of other functions selected prior to the
initiation of the lock feature will be displayed. If the
lock is engaged while a mode is active, the LED
will remain on until that mode times out.

If the lock is engaged when the filter timer expires,
the LED will come on but cannot be reset until the
lock is turned off.

The lock feature will be restored in the event of a
power disruption.

Filters

Some models are equipped with a water filter
located in the upper right-hand corner of the fresh
food compartment. The filter is designed to be
used for up to 8 hours of open valve time or 1 year
of calendar time.

When 90% of filter time (dependant on model) has
elapsed (open valve time or calendar time,
whichever comes first), the main control board will
illuminate the filter reminder LED (amber). When
100% of the filter time has elapsed, the main
control board will illuminate the filter reminder LED
(red).

The hinge brackets are not adjustable on the
cabinet. The fresh food door can be adjusted up
and down by using the hinge adjustment pin
(located on the fresh food lower door hinge).

The fresh food and freezer lower door hinges are
equipped with replaceable cam risers. The cam
risers assist in door closure. If the fresh food door
is adjusted too high, cam riser will not be engaged,
and the fresh food door will not close properly.

IMPORTANT: The refrigerator rollers must be
adjusted correctly for proper door closure. When
the rollers are adjusted correctly, the door should
close easily when open approximately 45 degrees
(halfway)

Airflow (Cabinet Interior)

The freezer compartment is designed so that
when the evaporator fan is operating, air is drawn
into the bottom of the air tunnel and through the
evaporator. The cold air is then pushed out into
the top of the freezer .

“Jelly Roll” Condenser

The fresh food compartment receives chilled air
via an electronic damper positioned at the top, rear
of the refrigerator between the freezer
compartment and the fresh f ood compartment.
The damper is controlled by the main control
board and when open, allows chilled air from the
freezer air tunnel to move into the fresh food
compartment.

Air returns from the fresh food compartment to the
freezer compartment via a vent located to the left
of the FRESH PRODUCE drawer.

The new NO CLEAN condenser is accessed from
the rear and is designed to be tolerant of up to 2
inches of lint. The idea is that 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 and
pulled out by the condenser fan. 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 in
from front left and rear left and exits out front right
side of refrigerator .
