Possible Causes
Door not fully closed, Excessive frost restricting airflow, Defective freezer fan, Refrigerant leak or compressor issue
How to Fix / Troubleshooting
Safety: Unplug the unit if you need to remove panels or defrost manually.
- 1. Confirm door closure: Check that the freezer door or drawer closes and latches properly. Remove items blocking closure.
- 2. Inspect for frost buildup: If the freezer is heavily frosted, perform a full manual defrost (unplug, doors open, towels on floor) and then restart.
- 3. Check fan operation: Listen for the freezer fan. If not running, refer to the evaporator fan motor fault entry.
- 4. Monitor temperatures: After defrost and corrections, allow 24 hours. If H2 returns and food remains soft, a sealed system or compressor fault is likely.
Professional service is recommended for suspected refrigerant or compressor problems.
