Overload Protector Failure

How to Identify: Compressor does not start; intermittent cycling; relay may show signs of overheating or arcing.

Part: Overload protector (compressor safety device)

Faulty Compressor

How to Identify: No sound from compressor even with proper power and relay, multimeter tests show open windings or internal failure.

Part: Compressor unit

Thermostat/Temperature Control Issues

How to Identify: Incorrect temperature settings or failed thermostat causing compressor not to engage when temperature not meeting threshold.

Part: Temperature control/thermostat
