WATER SUPPLY REQUIREMENTS
• Locate the boards so the bottom surface of
the boards are 84″ (213 cm) from the floor.
• During installation, raise the refrigerator up
so there is 1/4″ (6.4 mm) maximum between
the top of the refrigerator and the bottom of
the anti-tip boards. Do not crush the condenser cover when raising the rear leveling
legs.
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. Install copper tubing only in areas where temperatures will remain above freezing.

A kit is available with a 1/4″ (6.35 mm) saddletype shutoff valve, a union, and copper tubing.
Before purchasing the kit, make sure that a
saddle-type valve complies with local plumbing 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.

THE ELECTRONIC TEMPERATURE CONTROL PANEL
The electronic control monitors the water valve
for total elapsed time and gallons of water
used. The number displayed on the Water
Filter Indicator (WFI) is the percentage of filter
usage remaining.
The numeric display can be set for Fahrenheit
or Celsius and displays the actual temperatures. 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 concern over temperature fluctuations when the
doors are opened. Press the temperature adjustment 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
for 5 seconds.

• Over-Temperature Alarm
• Holiday Mode
OVERVIEW
The KitchenAid Built-In Refrigerator Constant
Flow Temperature Management System uses
two thermistors to monitor temperature changes
inside the refrigerator and freezer compartments. 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 compressor and the evaporator fan motor. Higher
fan speed is used before increasing the compressor speed to minimize power consumption. 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 temperatures 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).
3-1
TEMPERATURE CONTROL
Freezer Temperature Control —
Temperature Decreasing
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 compressor 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.
When the freezer temperature begins to decrease, the process will reverse. The compressor speed decreases, followed by the evaporator 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 compressor starts to run, or if it has already been
running, begins to increase in speed.
Refrigerator Temperature Control —
Temperature Decreasing
Freezer Temperature Control —
Temperature Increasing
As the refrigerator temperature approaches the
selected setting, the control compares the temperatures in both compartments to determine
which compartment will control the fan speed.
If the freezer is further from the selected temperature setting, it controls the fan speed, and
the air door begins to close, thus reducing the
airflow to the refrigerator.
When the freezer calls for cooling, the compressor 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 updated. Speed changes are made based on:
• The difference between the actual temperature 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 compressor speed of 4500 rpm will be reached at
9°F above the selected temperature setting.
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.
3-2
COMPRESSOR
COMPRESSOR PROTECTION
The main control board supplies a 5 vdc, peakto-peak square wave, at 54 to 150 Hz, to the
inverter board. A standard VOM will read approximately 2.5 vdc. The inverter board supplies 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.
To protect the compressor and maintain efficiency, minimum compressor off time is programmed into the control. When the compressor 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
NOTE: It is not necessary, nor is it recommended, to test the output of the inverter board.
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.
While the compressor is running, its speed is
continuously updated. Speed is determined
after analyzing two factors:
• The difference between the actual temperature 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.
Freezer Temperature

• 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 evaporator prior to starting the fan. Immediately after 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 compressor generally cycles on and off
according to the cut-in and cut-out temperatures 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.
3-3
POWER INTERRUPTION
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 recover refrigerator temperature.
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 interruption. 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 compressor 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.
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 compressor 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 compressor has run at 4000 rpm or greater for 1
hour, and 8 hours have elapsed since the last
defrost.
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.
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 allow a technician time to look for heater operation, and if necessary, bypass the bimetal.
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 temperature 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. Setting the freezer warmer, or the refrigerator
colder, will increase the door-open time.
3-4
Freezer Thermistor
MAX COOL MODE
If the control senses an open or a shorted thermistor, 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. Setting 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.
Max Cool changes the refrigerator temperature 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 displays 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 temperature 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 difference between actual freezer temperature
and -9°F (-23°C).
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 indefinite period, except during the defrost periods.
The “Call Service Alarm” will sound until the
failure has been corrected.
HOLIDAY MODE
The Holiday Mode may be used for the following occasions:
• On vacation.
• Religious observance (Sabbath Mode).
ELECTRONIC CONTROL
THERMAL SHUTOFF
The electronic control utilizes an on-board thermistor to shut the compressor off if the temperature rises above 160°F (71°C). When the
temperature drops to 130°F (55°C), the compressor 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.
When the Holiday Mode is selected, the corresponding green LED flashes for 2 seconds,
and then remains on, to indicate that the feature is activated.
3-5
In the Holiday Mode the following occurs:
• Temperature selections remain at the current 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 regardless of the door position.
• Keypad operation is disabled, with the exception of the Holiday Mode key, or the
Power On/Off key.
freezer temperature exceeds 15°F (–9°C) for
over 1-1/2 hours. The appropriate temperature
display flashes to show the user which compartment 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 OverTemperature 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 service. 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.
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 settings in either compartment.
DOOR OPEN ALARM
If either door is left open for more than 10 minutes, 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.
When the Holiday Mode is cancelled, the Holiday Mode LED turns off, and the control reverts to the settings in use prior to activation.
All inactive devices are restored, and the Water Filter Indicator is updated.
The Adaptive Defrost Control function is not
effected by use of the Holiday Mode.
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.
OVER-TEMPERATURE ALARM
The Over-Temperature Alarm sounds, and the
indicator light flashes when either the refrigerator temperature exceeds 48°F (9°C), or the
3-6
AIR CIRCULATION
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 management system will not function properly.
IMPORTANT: Because air circulates between
both sections, any odors formed in one section will transfer to the other. Keep both sections clean, and wrap or cover foods tightly to
prevent odors from occurring.
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 compartment 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 motorized air door. The refrigerator air then returns to
the freezer through the bottom air return (see
the illustration below).
