Feedback of fresh food thermistor value. Thermistor is NTC, when temperature drops, resistance
value increases, causing return voltage reduction. This value is used to cycle fresh food fan
(when used), evaporator fan, compressor, and condensor fan. Feedback is filtered to respond to
8 degrees of change per minute.
Feedback of second fresh food thermistor value (when used). Thermistor is NTC, when
temperature drops, resistance value increased, causing return voltage reduction. This value is
used to cycle fresh food fan (when used), evaporator fan, compressor, and condensor fan.
Feedback is filtered to respond to 8 degrees of change per minute.
Feedback of freezer thermistor value. Thermistor is NTC, when temperature drops, resistance
value increases, causing return voltage reduction. This value is used to cycle evaporator fan,
compressor, and condensor fan, and will not cycle fresh food fan (when used). Feedback is
filtered to respond to 8 degrees of change per minute.
Feedback of evaporator thermistor value. Thermistor is NTC, when temperature drops, resistance
value increases, causing return voltage reduction. This thermistor value is used to cycle the
heater on during defrost when temperature is below defrost value and off when the temperature
is above defrost value. This value is also read during power-up to determine if refrigerator goes
into pulldown mode or cycle continuation. Feedback is unfiltered, responds immediately.
Provides 5 VDC for thermistors and personality pins on J1.
