OVERVIEW

The electronic control for 2001 KitchenAid Side-by-Side refrigerators combines several functions

previously used in separate components: Adaptive Defrost Control (ADC), Independent Temperature Control (ITC) and Water Filter Indicator Control (WFI). Two new technologies, pulsed defrost and evaporator fan delay, are incorporated into this control.

The numeric display can be set for Fahrenheit or Celsius and will display customer temperature settings. Available features will include: Max Cool and Over Temperature Alarm.

THEORY OF OPERATION

The control runs a 13 second self-diagnostic routine prior to starting a cooling cycle every time it is plugged into a wall outlet. The compressor will start approximately 10 seconds into the self-diagnostic routine.

Refrigerator Temperature Control

A motorized air baffle is used to regulate air flow from the freezer into the refrigerator compartment. The air baffle operation is controlled by input from the refrigerator thermistor. The refrigerator control allows the customer to select a temperature range of 33°F (1°C) to 41°F (9°C). When the refrigerator thermistor senses a temperature above the customer setting, the baffle opens and the evaporator fan motor begins to run. The compressor may or may not be running at this time based on the temperature in the freezer. The baffle closes when the refrigerator temperature setting is reached.

Freezer Temperature Control

Input from the freezer thermistor is used by the control to determine compressor run time. The freezer thermistor allows the customer to select a temperature setting of -5°F (-21°C) to +5°F (-15°C). When the freezer thermistor senses a temperature above the customer setting, the control immediately energizes the compressor. The evaporator fan motor is energized after a 40-second delay. This delay allows the evaporator to begin to cool before air is circulated. If the evaporator fan is already running to cool the refrigerator section, it will continue without delay. The compressor turns off when the proper freezer temperature is reached, but the evaporator fan continues to run for 2 minutes. To protect the compressor, the control will not allow the compressor to restart for a minimum of 6 minutes.

Failure Defaults

To provide a measure of customer satisfaction in the event of a thermistor or keypad failure, the control will use one of the following default modes. The default mode continues until the failure is corrected.

•Refrigerator Thermistor: If the refrigerator thermistor fails, the control will cycle the baffle open for 10 minutes, closed for 10 minutes. The evaporator fan will run when the baffle is open.

•Freezer Thermistor: If the freezer thermistor fails, the compressor and evaporator fan will cycle on and off together in 15-minute intervals.

•Keypad Failure Mode: If the control detects that the keypad is not working, it will default to temperature regulation of 0°F (-18°C) for the freezer and 37°F (3°C) in the refrigerator.
