THEORY OF OPERATION
THE ELECTRONIC CONTROL
OVERVIEW
The KitchenAid Built-In French Door Bottom­Mount Refrigerator Constant Flow Temperature Management System uses two thermistors to monitor temperature changes inside the refrigerator and freezer compartments. Two electronic control boards are used in the re-
rigerator: a main electronic control board,
f and a low voltage (Phoenix) board. The main electronic control board 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.
main electronic control board seeks the
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.

TEMPERATURE CONTROL
The main electronic control board checks the resistance of the thermistors, and compares it to both the customer temperature settings and the last thermistor reading taken. This infor­mation cooling operation, and if a change is necessary in the damper setting, or the evaporator fan or compressor speed.
When ing 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 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 com­pressor 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:

When the freezer temperature begins to de-

p evaporator fan speed.
Refrigerator T 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 in-
rease in speed.

Refrigerator Temperature Control — Temperature Decreasing
As the refrigerator temperature approaches the selected setting, the control compares the temperatures in both compartments to deter­mine 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.
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.

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.
To protect the compressor and maintain ef­ficiency, minimum compressor off time is pro-
rammed into the main control board. When the
g compressor turns off, a minimum of 7 minutes must elapse before allowing a restart.
t the end of the 7-minute period, the condenser
A fan motor starts, and the main control board sends the compressor speed signal to the inverter. The compressor will not start for an additional minute, due to the inverter delay.
The inverter utilizes a current-limiting device and thermal protection that eliminates the need for a compressor-mounted thermal protector. The inverter will not allow a compressor restart for 8 minutes after the compressor turns off. This inverter delay will not occur after a power interruption, because inverter memory is lost (see “Power Interruption” on page 3-4).
EVAPORATOR FAN MOTOR
The evaporator fan motor is a 12 vdc, variable speed motor. The motor has four wires:
A blue wire that is not used.
• 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.
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 evapora-
prior to starting the fan. Immediately after
tor defrost drip time, the compressor starts at 4500 rpm, but the evaporator fan is delayed for 8 minutes. Also, the air door remains closed during the 8-minute delay.

AIR DOOR
The air door is driven by a reversible DC stepper motor. The motor operates on a 12 vdc, peak­to-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.
eparate windings are used to move the air door
S open or closed. The door can be in any position 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 recover refrigerator temperature.
ADAPTIVE DEFROST
The adaptive defrost control function of the main electronic control board allows the refrigerator 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 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.

The control monitors the temperature of each ingredient care center pan by means of a thermistor located in the top of each pan. When cooling is needed the Phoenix control sends a request to the main control board to operate the evaporator fan motor. The Phoenix control board does not have direct control of the evaporator fan motor. The Phoenix control also sends a 12 vdc, peak to peak square wave to the ingredient care center air door to open the door.
The ingredient care center air door will be in one of five possible positions based on the ingredient care center user setting. The air door will close at any setting when the proper temperature has been reached. Here are the four possible positions and temperatures for each setting.

AIR CIRCULATION
In order to ensure proper temperatures, you need to permit airflow between the refrigerator and freezer sections. As shown in the illustra-
cool air enters the freezer section through

It 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 help avoid the transfer of odors from food to ice.
