Openings
The built-in refrigerator can be installed into a
recessed opening in the cabinets, or at the end
of cabinets using a side panel to enclose the
refrigerator side. The installation requires a
1/2″ (12.7 mm) clearance to remove the top
grille and for proper air flow.
Wall studs must be located on the rear wall 80″
to 90″ (203 - 229 cm) above the floor.
The solid soffit must be within 1″ (2.5 cm)
maximum above the refrigerator. If the solid
soffit is higher than 1″ (2.5 cm), or one is not
available, then the refrigerator must be braced
to prevent tipping during use. See “Anti-Tip
Boards” on page 2-3.
A grounded electrical outlet should be placed
in the top shaded area, 4″ (10.2 cm) from the
right side of the cabinets or end panel.
The water shutoff should be located in the base
cabinet on either side of the refrigerator. The
right side is recommended. The access hole
through the right cabinet must be within 1/2″
(12.7 mm) of the rear wall.
A 1/2″ (12.7 mm) hole for plumbing should be
within the bottom shaded area. The water line
can be through the floor or wall. If the recom-
mended water line location is used, no addi-
tional plumbing is necessary.

WATER SUPPLY REQUIREMENTS
IMPORTANT:
• If you turn the refrigerator on before the
water line is connected, turn the ice maker
off.
• All installations must meet local plumbing
code requirements.
• Use copper tubing and check for leaks. In-
stall copper tubing only in areas where tem-
peratures will remain above freezing.
A kit is available with a 1/4″ (6.35 mm) saddle-
type shutoff valve, a union, and copper tubing.
Before purchasing the kit, make sure that a
saddle-type valve complies with local plumb-
ing codes. Do not use a piercing-type or a 3/16″
(4.76 mm) saddle valve because they reduce
water flow and clog easily.
Connect the ice maker to a cold water line with
water pressure between 15 and 100 psi (103 -
690 kPa). If you have questions about water
pressure, contact the water utility company.
ANTI-TIP BOARDS
IMPORTANT:
• The solid soffit must be within 1″ (2.5 cm)
maximum above the refrigerator. If the solid

LOWERING THE LEVELING LEGS
All four leveling legs must contact the floor to
support and stabilize the full weight of the
refrigerator. Rollers are for moving the refrig-
erator, and not for permanent support.
Use a socket wrench to turn the leg levelers on
both sides of the refrigerator to the right (clock-
wise) until the refrigerator weight is supported
by the legs. The rollers should be off the floor.
To avoid cabinet damage, do not apply more
than 50 in/lbs (58 cm/kg) of torque to the
leveling legs.

THEORY OF OPERATION
OVERVIEW
The KitchenAid Built-In Refrigerator Constant
Flow Temperature Management System uses
two thermistors to monitor temperature changes
inside the refrigerator and freezer compart-
ments. The electronic control manages the
operation of the variable capacity compressor
(VCC), a variable speed evaporator fan motor,
and a variable position air door. The air door
allows independent temperature control of the
refrigerator and freezer compartments.
The electronic control seeks the most efficient
means possible to maintain temperatures as it
controls the operation and speed of the com-
pressor and the evaporator fan motor. Higher
fan speed is used before increasing the com-
pressor speed to minimize power consump-
tion. A nearly constant run time is sought at the
lowest possible fan and compressor speed.
Freezer temperatures can be set from 9°F to
–9°F (–13°C to –23°C). Refrigerator tempera-
tures can be set from 46°F to 32°F, (8°C to
0°C).
The Adaptive Defrost Control (ADC) portion of
the electronic control utilizes “pulsed defrost”
technology to perform the defrost function (see
page 3-4).

The numeric display can be set for Fahrenheit
or Celsius and displays the actual tempera-
tures. The display range for the refrigerator is
from 27°F to 70°F. The normal freezer display
range is from –9°F to 70°F. Temperatures
above or below these limits will be displayed at
the corresponding temperature limit. During
Max Cool, the freezer display will read –10°F,
and the refrigerator will read 32°F.
The display will show the temperature setting
any time the actual temperature is within ±6°F
of the customer setting. This will prevent con-
cern over temperature fluctuations when the
doors are opened. Press the temperature ad-
justment key to view the current temperature
setting, or to change the setting. When the
temperature adjustment key is used to change
the temperature setting, the display will brighten

Freezer Temperature Control —
Temperature Decreasing
When the freezer temperature begins to de-
crease, the process will reverse. The compres-
sor speed decreases, followed by the evapo-
rator fan speed.
Refrigerator Temperature Control —
Temperature Increasing
When the refrigerator calls for cooling while
the freezer is satisfied, the air door begins to
open, and the evaporator fan starts to run at
minimum speed. If the temperature continues
to rise, the air door will continue to open. If the
temperature continues to rise after the air door
is fully open, the evaporator fan speed will
gradually increase to a maximum of 3000 rpm.
If the temperature continues to rise, the com-
pressor starts to run, or if it has already been
running, begins to increase in speed.
Refrigerator Temperature Control —
Temperature Decreasing
As the refrigerator temperature approaches the
selected setting, the control compares the tem-
peratures in both compartments to determine
which compartment will control the fan speed.
If the freezer is further from the selected tem-
perature setting, it controls the fan speed, and
the air door begins to close, thus reducing the
airflow to the refrigerator.
If the freezer is satisfied, the air door remains
open, and the fan speed begins to decrease.
When the selected temperature setting is
reached, the air door closes.
TEMPERATURE CONTROL
The electronic control checks the resistance of
the thermistors, and compares it to both the
customer temperature settings and the last
thermistor reading taken. This information is
used to determine when to begin a cooling
operation, and if a change is necessary in the
damper setting, or the evaporator fan or com-
pressor speed.
When a warm refrigerator is first put into a
cooling mode, the air door partially opens, and
the compressor and evaporator fan motors
start to run at maximum rpm. The air door will
gradually move to its fully open position.
As the actual temperature in the refrigerator
nears the selected temperature setting, the
electronic control compares the temperatures
in both compartments. The compartment that
has the greatest need for cooling, will control
the speed of the evaporator fan motor.
Freezer Temperature Control —
Temperature Increasing
When the freezer calls for cooling, the com-
pressor begins to run at minimum rpm, (see the
chart on page 3-3), and the evaporator fan
begins to run at 2000 rpm. The compressor
and evaporator speeds are continuously up-
dated. Speed changes are made based on:
• The difference between the actual tempera-
ture and the selected temperature settings.
• The rate of temperature change.
If the temperature increases 4°F above the
selected temperature setting, the evaporator
fan speed begins to gradually increase. The
evaporator fan motor reaches the maximum
speed of 3000 rpm at 5°F above the selected
temperature setting, and the compressor speed
begins to gradually increase. A maximum com-
pressor speed of 4500 rpm will be reached at
9°F above the selected temperature setting.

COMPRESSOR
The main control board supplies a 5 vdc, peak-
to-peak square wave, at 54 to 150 Hz, to the
inverter board. A standard VOM will read ap-
proximately 2.5 vdc. The inverter board sup-
plies the variable capacity compressor with
three-phase 230 vac. Varying the frequency
to the inverter board, and not the voltage,
changes the speed of the compressor. The
compressor can run at speeds of 1620 to 4500
rpm.
NOTE: It is not necessary, nor is it recom-
mended, to test the output of the inverter board.
While the compressor is running, its speed is
continuously updated. Speed is determined
after analyzing two factors:
• The difference between the actual tempera-
ture and the selected temperature settings.
• The rate of temperature change.
Minimum compressor speed is based on the
freezer’s selected temperature setting, as
shown in the following chart.
The compressor generally cycles on and off
according to the cut-in and cut-out tempera-
tures of the freezer, however, the refrigerator
can turn on the compressor if the evaporator
fan is at maximum speed and the refrigerator
temperatures are not dropping.
COMPRESSOR PROTECTION
To protect the compressor and maintain effi-
ciency, minimum compressor off time is pro-
grammed into the control. When the compres-
sor turns off, a minimum of 7 minutes must
elapse before allowing a restart.
The inverter board utilizes a current limiting
device and thermal protection that eliminates
the need for a compressor mounted thermal
protector.
EVAPORATOR FAN MOTOR
The evaporator fan motor is a 12 vdc, variable
speed motor. The motor has four wires:
• A blue wire provides feedback to monitor the
speed of the motor.
• A red wire provides a constant 12 vdc.
• A yellow wire provides a variable voltage of
between 5 vdc and 17 vdc to control the
motor speed from 2000 to 3000 rpm.
• A white wire provides a common return.
EVAPORATOR FAN &
AIR DOOR DELAY
After defrost, an evaporator fan delay prevents
unnecessary movement of warm, moist air
through the refrigerator, by chilling the evapo-
rator prior to starting the fan. Immediately af-
ter defrost drip time, the compressor starts at
4500 rpm, but the evaporator fan is delayed
for 8 minutes. The air door remains closed for
8 minutes following defrost.
AIR DOOR
The air door is driven by a reversible DC
stepper motor. The motor operates on a 12
vdc, peak-to-peak square wave. Voltage is
delivered to the air door in a series of short
pulses. It is not possible to obtain a reliable
voltage reading with a VOM.
Separate windings are used to move the air
door open or closed. The door can be in any
one of 1800 positions from 0 to 90 degrees.
The air door is used to fine-tune the airflow to
the refrigerator.

The refrigerator temperature determines the
opening of the air door. When the refrigerator
requires cooling, if the evaporator fan motor is
already running for the freezer, the air door
partially opens, and then adjusts, if necessary.
While the refrigerator is cooling, the door will
be adjusting continuously to maintain or re-
cover refrigerator temperature.
ADAPTIVE DEFROST
The adaptive defrost control allows the unit to
enter a defrost mode only when it is needed.
When powered up for the first time, the control
initiates a defrost cycle after 8 hours of com-
pressor run time. By monitoring the duration of
defrost heating time and compressor run time,
the control will continuously adapt the time
between defrosts to optimize efficiency. Time
between defrost periods will vary between 8
and 100+ hours.
Defrost will occur immediately when the com-
pressor has run at 4000 rpm or greater for 1
hour, and 8 hours have elapsed since the last
defrost.
PULSED DEFROST
For the first 2 minutes of defrost, the heater is
on continuously. It will then cycle off for 1
minute, and back on for 2 minutes. The heater
will continue to cycle at this ratio until the
bimetal opens, or until 33 minutes has elapsed.
At this point, heat is discontinued, and a
4-minute “drip time” begins. This allows the
water to drain before the unit returns to a
cooling mode. Maximum defrost time, (pulsed
heat on/off time + drip time) is 37 minutes.
When entering a defrost cycle, if the bimetal is
open, the time to defrost is reset to 8 hours, and
the control will time through the entire 37 minute
defrost period. During diagnostics this will al-
low a technician time to look for heater opera-
tion, and if necessary, bypass the bimetal.
POWER INTERRUPTION
After a power interruption, the following events
will occur:
• The unit returns to the same operating mode
and settings in use prior to the power inter-
ruption. If the unit was off, it remains off.
• Initially, the compressor, evaporator fan, and
condenser fan motors will be off.
• The air door will close, and then adjust to the
proper opening. The evaporator fan starts
when the air door opens.
• The adaptive defrost control resets the com-
pressor run time counter to 0, and if the
freezer is above 20°F, the time to defrost is
set to 8 hours.
• If the freezer temperature is below 12°F, the
compressor starts after a delay of 7 minutes.
If the freezer temperature is above 12°F, the
compressor starts immediately.
FAILURE DEFAULTS
In the event of a thermistor, or keypad failure,
the control uses one of the following default
modes, which will continue until the failure is
corrected.
Refrigerator Thermistor
If the control senses an open or a shorted
thermistor, the air door and the evaporator fan
motor will begin to operate on a timed on and
off cycle, based on current selected tempera-
ture settings. The evaporator fan motor will run
when the air door is open.
At mid-settings of 37°F / 0°F, the air door will
open for 16 minutes, and close for 30 minutes.
Setting the freezer colder, or the refrigerator
warmer, will reduce the door-open time. Set-
ting the freezer warmer, or the refrigerator
colder, will increase the door-open time.
Downloaded from www.ManualsFile.com manuals search engine
3-5
Freezer Thermistor
If the control senses an open or a shorted ther-
mistor, the compressor and the evaporator fan
motor will begin to operate on a timed on and
off cycle. The cycle time is based on current
selected temperature settings.
At mid-settings of 37°F / 0°C, the compressor
and the evaporator fan motors will run for 35
minutes, and be off for 25 minutes. Setting the
freezer colder will increase the run time. Set-
ting the freezer warmer will decrease the run
time.
The compressor will run at minimum speed.
The evaporator fan will also run at minimum
speed, unless the refrigerator compartment
requests a higher speed.
Keypad
If the control detects that the keypad is not
working, it reverts to the default temperature
settings of 37°F in the refrigerator, and 0°F in
the freezer.
Evaporator Fan Motor
If the evaporator fan motor malfunctions, the
compressor will run at 4500 rpm for an indefi-
nite period, except during the defrost periods.
The “Call Service Alarm” will sound until the
failure has been corrected.
ELECTRONIC CONTROL
THERMAL SHUTOFF
The electronic control utilizes an on-board ther-
mistor to shut the compressor off if the tem-
perature rises above 160°F (71°C). When the
temperature drops to 130°F (55°C), the com-
pressor returns to normal operation. This cycle
continues indefinitely until the cause of the high
temperature has been corrected.
If this cycle is repeated four times within 24
hours, the “Call Service” indicator lights, and
the alarm sounds.
MAX COOL MODE
Max Cool changes the refrigerator tempera-
ture setting to 32°F (0°C) and the freezer to
–10°F (–23°C) for 24 hours. During Max Cool,
the freezer and refrigerator temperature dis-
plays show the new temperature settings, not
the actual temperatures.
In most cases the motors run 100% for more
than 1 hour. The control returns to the previous
user setting after 24 hours, or any time the
temperature settings are changed.
AUTOMATIC MAX ICE
Automatic Max Ice operates any time the ice
maker water valve is energized. The duration
of Automatic Max Ice is 1-1/2 hours. During
Automatic Max Ice the following occurs:
• The freezer display shows the user tempera-
ture settings and not the actual temperature.
• The freezer temperature setting changes to
–9°F (–23°C).
• The evaporator fan runs at 3000 rpm.
• The compressor runs the entire 1-1/2 hour
mode. Speed is determined by the differ-
ence between actual freezer temperature
and -9°F (-23°C).
HOLIDAY MODE
The Holiday Mode may be used for the follow-
ing occasions:
• On vacation.
• Religious observance (Sabbath Mode).
When the Holiday Mode is selected, the corre-
sponding green LED flashes for 2 seconds,
and then remains on, to indicate that the fea-
ture is activated.
Downloaded from www.ManualsFile.com manuals search engine

In the Holiday Mode the following occurs:
• Temperature selections remain at the cur-
rent setting, but are not displayed.
• The Water Filter Indicator is not displayed,
but monitoring continues.
• The audible signals are disabled.
• The ice maker is disabled.
• The interior lights are disabled.
• The temperature displays and all of the LEDs
will be off, except for the Holiday Mode LED.
The Holiday Mode LED will illuminate re-
gardless of the door position.
• Keypad operation is disabled, with the ex-
ception of the Holiday Mode key, or the
Power On/Off key.
The Holiday Mode will be cancelled if one of the
following occurs:
• Pressing the Power On/Off, or Holiday Mode
keypads.
• Failure of both thermistors.
• No feedback from the evaporator fan motor.
• Temperatures that are 15°F above user set-
tings in either compartment.
When the Holiday Mode is cancelled, the Holi-
day Mode LED turns off, and the control re-
verts to the settings in use prior to activation.
All inactive devices are restored, and the Wa-
ter Filter Indicator is updated.
The Adaptive Defrost Control function is not
effected by use of the Holiday Mode.
OVER-TEMPERATURE ALARM
The Over-Temperature Alarm sounds, and the
indicator light flashes when either the refrig-
erator temperature exceeds 48°F (9°C), or the
freezer temperature exceeds 15°F (–9°C) for
over 1-1/2 hours. The appropriate temperature
display flashes to show the user which com-
partment is effected. The alarm stops if the
temperature(s) returns to normal, but the red
Over-Temperature indicator and temperature
display will continue to flash. Pushing the Over-
Temperature Reset key turns off the Alarm and/
or indicator, and resets the Over-Temperature
Timer to zero.
CALL SERVICE ALARM
Call Service is a visual and audio signal that
alerts the user that the refrigerator needs ser-
vice. The Call Service Alarm will sound when:
• Both thermistors have failed.
• The evaporator fan motor loses its feedback
signal.
• An over-temperature condition occurs for 3
hours or more.
DOOR OPEN ALARM
If either door is left open for more than 10 min-
utes, the interior lights will be disabled, the
Door Open icon will flash, and the alarm will
sound. If the door is closed during the alarm
operation, the alarm will reset, but the icon will
continue to flash until the temperature in the
refrigerator drops below 45°F (7°C) and the
freezer is below 15°F (–9°C). Pressing the
Over-Temperature Alarm/Reset key resets the
Alarm and the flashing Icon.
SALES DEMONSTRATION MODE
This mode provides a sequential display of the
temperature displays and feature LEDs. To
enter the Demonstration Mode, press and hold
the Max Cool and Power On/Off keys for 2
seconds. If the refrigerator or freezer door is
open for 10 minutes, the interior lights will turn
off.

AIR CIRCULATION
In order to ensure the proper refrigerator and
freezer compartment temperatures, air must
be able to flow between the two sections.
Air enters the bottom of the freezer compart-
ment and moves up through the evaporator.
Some of the cooled air from the evaporator is
directed back into the freezer, and the rest
goes into the refrigerator through the motor-
ized air door. The refrigerator air then returns to
the freezer through the bottom air return (see
the illustration below).
It is important not to block any of the vents with
food items. If the vents are blocked, airflow will
be restricted, and the temperature manage-
ment system will not function properly.
IMPORTANT: Because air circulates between
both sections, any odors formed in one sec-
tion will transfer to the other. Keep both sec-
tions clean, and wrap or cover foods tightly to
prevent odors from occurring.

COMPONENT TESTING
Before testing any of the components, perform
the following checks:
• The most common cause for control failure is
corrosion on connectors. Therefore, discon-
necting and reconnecting wires will be nec-
essary throughout test procedures.
Refer to page 4-18 for the procedure for servic-
ing a thermistor.
1. Run the diagnostics tests (see page 6-1)
and test the thermistors in steps 01 and
02.
NOTE: For accurate temperature/resistance
readings, continue with the remaining steps to
check the resistance of the thermistor(s).
2. Unplug the refrigerator or disconnect the
power.
3. Disconnect the thermistor wire connector
from the main harness.
4. Set the ohmmeter to the R x 1K scale.
5. Insert the test probes into the two connec-
tor pins of the thermistor connector.
THERMISTOR
NOTE: If the resistance of the thermistor(s)
was normal, perform the following voltage test.
1. Set the voltmeter to read a maximum
voltage of 10 volts DC.
2. Connect power to the refrigerator and
allow it to enter the “cooling” mode.
3. With the thermistor disconnected and the
refrigerator in the cooling mode, touch the
voltmeter test probes to the thermistor
main harness connector pins. The meter
should indicate approximately 5 volts DC.
If the voltage was not present, check for a
thermistor output at the main control board
(see page 5-5).
6. Depending on the temperature, the meter
should indicate within the approximate
range, as shown in the chart below.
• Check all connections before replacing com-
ponents, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.

Refer to pages 4-4 and 4-9 for the procedures
for servicing the inverter and compressor.
1. Run the diagnostics tests (see page 6-1)
and check for the proper operation of the
compressor in step 05.
NOTE: If the compressor does not operate
perform the following steps.
2. Connect power to the refrigerator and
allow it to enter the “cooling” mode.
3. While the refrigerator is in the cooling
mode, the inverter and main control board
voltages should be as shown in the chart
below.
4. Set the voltmeter to read the voltages
shown in the chart.
• If the 3 to 6 volts DC is not present at
the inverter red/white and red wires,
check P7-3 and P7-8 on the main con-
trol board for 3 to 6 volts DC. If the volt-
age is not present, replace the main
control board.
Pins
Electrical Shock Hazard
Disconnect power before servicing.
Replace all panels before operating.
