About the Thermistor

The thermistor monitors the freezer temperature and sends the temperature reading to the control board. The control board regulates power to the compressor and evaporator fan based on the thermistor readings. If the thermistor is defective, the compressor and evaporator fan may not run when necessary. As a result, the freezer may not freeze properly. To determine if the thermistor is defective, test it with a multimeter. The thermistor resistance should change in conjunction with the freezer temperature. If the thermistor resistance does not change, or the thermistor does not have continuity, replace the thermistor.
