Possible Causes
Faulty main control board, Defective thermostat not sending call for cooling, Open wiring in power circuit to compressor, Safety thermal fuse open (if equipped)
How to Fix / Troubleshooting
Safety first: Unplug the freezer before removing any covers or testing wiring.
- Check temperature setting: Ensure the unit is not set to OFF or a demo mode. Adjust to a colder setting.
- Test outlet: Plug another appliance into the same outlet to confirm power.
- Inspect control board: Look for burnt components or loose connectors on the main PCB.
- Thermostat bypass test (mechanical models, advanced DIY): With power disconnected, temporarily join the thermostat wires to simulate a call for cooling. If the compressor starts when power is restored, the thermostat is faulty and should be replaced.
- Replace faulty control: If the thermostat is good but the board does not energize the compressor, replace the main control board.
