Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the freezer before accessing the fan area.
Steps:
- Access fan: Remove drawers and the rear interior panel. The evaporator fan is mounted near the top or center of the evaporator housing.
- Check for ice obstruction: Look for ice around the fan shroud and blades. If present, defrost the unit fully by turning it off and leaving the door open until all ice melts.
- Spin test: Gently spin the fan blades by hand. They should rotate freely without grinding or stiffness.
- Wiring check: Inspect the fan connector and wiring for damage or loose plugs.
Remedy: If the fan is seized or does not run when powered (after defrosting and reassembly), replace the evaporator fan motor assembly with a Liebherr-compatible part. Ensure the fan blades are correctly oriented and the shroud is properly fitted to direct airflow.
