Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the freezer before accessing the rear compartment or control board.
Step-by-step checks:
- 1. Verify setpoint: Ensure the control is set to a cold enough temperature to demand cooling.
- 2. Check wiring: Inspect the harness from the main board to the compressor for breaks or loose connectors.
- 3. Listen for relay: When cooling should start, listen for a click from the main board. No click may indicate a failed relay or control board.
- 4. Replace main board: If wiring and compressor are good but the relay does not energize, replace the main control board.
