How to Fix / Troubleshooting

Safety first: Unplug the freezer before accessing rear components or control housing.

Steps:

  • Check temperature setting: Ensure the control is not set to OFF or the warmest setting.
  • Test thermostat/control: On mechanical models, bypass the thermostat temporarily by connecting its two wires together (for testing only). If the compressor starts, replace the thermostat. On digital models, suspect the main control board.
  • Inspect start relay: Access the compressor and test/replace the start relay and overload if defective.
  • Check wiring: Look for loose or burned connectors between the control and compressor.

Warning: Do not leave the thermostat bypassed; it is only for brief testing.
