IMPORTANT SAFETY NOTICE -'For Technicians Only' This service data sheet is intended for use by persons having electrical, electronic, and mechanical experience and knowledge at a level generally considered acceptable in the appliance repair trade. Any attempt to repair a major appliance may result in personal injury and property damage. The manufacturer or seller cannot be responsible, nor assume any liability for injury or damage of any kind arising from the use of this data sheet.

Self Diagnosis: Press Energy Saver and Lighting buttons simultaneously for 8-12 seconds, (No sound when both buttons are pressed at the same time) until the display quits blinking and beeps, then release the buttons and read Fault Codes. This will also cancel the Fault Mode created by self-diagnosis at power up.

Forced Mode: Press Energy Saver and Power Cool buttons simultaneously for 8-12 seconds, (No sound when both buttons are pressed at the same time) until the display beeps and goes blank.

Table Caption: This table lists various electrical components of an appliance, detailing their resistance, wattage, and voltage ratings. It includes heating elements for defrosting and other functions, a damper, sensors, and fans, with specified operating voltages for each.

Sensors

Defrost The sensor voltage tells the Main PCB to turn off the Defrost Heater at 50 o F in Freezer, 63 o F in Refrigerator Section

Compartment Temp The sensor controls fan/compressor on/off to maintain temperature.

Ice Production Ice maker harvests when the I/M sensor reads 1.5 o F for 5 minutes (Flex Tray Only). If the door is opened during that 5 minutes, harvest is delayed.

Ambient Sensor

Fan Speeds - Below 60 degrees, condenser fan is off.

Heat Release Ice Makers

Heat Release Ice production Explanation

38 minutes after the water fill is complete, the control board will check the temperature of the eject Thermistor, located on the Ice Maker Head. If the Thermistor reads a temperature lower than 18.5°F for more than 5 seconds, the ice production process is completed. The Ice Maker will harvest if the ice bucket is not sensed as full. If a Fault Mode is detected with the Ice Maker operation, the Ice Maker stops working for 3 hours. This means the Ice Maker will check the operation every 3 hours until it works properly.

Heat Release I/M Test Mode

Press and hold the Ice Test Switch for at least 1.5 seconds. The harvest function will start. If the Ice Maker Thermistor is below 0°F, the Ice Maker heater turns on for about 2 minutes. If the temperature exceeds 0°F, the Ice maker heater turns on for 30 seconds, then turns off and the Ice maker harvest motor turns on. The motor will rotate in a clockwise direction for about 3 minutes, the water supply valve is turned on then off and the test mode is completed. If this operation is not carried out within 6 minutes, it will go into a fault mode.

FREEZER TEMPERATURE CONTROLLED BY THE ICE MAKER

Interior Temperature of the freezer will be set to -14°F until the ice bucket is full. When the ice bucket is full, the freezer will maintain original set temperature. Also, whenever the ice bucket is not full, the freezer will again set to -14°F.

Selecting "Ice Off' will allow the freezer to be controlled by the set temperature.

If water is not hooked up, the freezer will always be at -14 unless 'Ice Off' is selected.
