How to Identify: Freezer doesn’t regulate temperature properly; multimeter test shows thermistor resistance doesn’t change with temperature.

Part: Thermistor

Start relay or start device failure

How to Identify: Compressor does not start or runs intermittently; relay smells burnt or fails continuity test.

Part: Start relay/start device on compressor

Faulty thermostat/control board

How to Identify: Irregular compressor/fan cycles; incorrect temperature demands; control board diagnostics fail.

Part: Thermostat/Control board

Door gasket air leak

How to Identify: Warm air enters; visible gaps or failed dollar test; freezer warms despite running components.

Part: Door gasket/seal
