How to Fix / Troubleshooting
Safety first: Unplug the freezer. Water from melting frost can create slip hazards and electrical risks.
Immediate temporary fix:
- Remove food to a backup freezer or cooler.
- Leave the freezer door open and allow it to fully defrost for 12–24 hours, placing towels to catch water.
- After defrosting, restart the freezer and monitor performance.
Permanent repair steps:
- Access the evaporator and inspect the defrost heater and thermostat as described in E4/E5.
- Replace any failed defrost components.
- If all components test good, the main control board may not be sending power to the heater and should be replaced.
