Possible Causes
Failed circulation fan motor between zones, Obstruction by bottles or shelves, Broken fan wiring
How to Fix / Troubleshooting
Safety first: Unplug the unit before removing interior panels or touching the fan.
Steps:
- 1. Identify circulation fan: On some Liebherr multi-zone models, a fan between compartments equalizes temperature. It is often behind a grille between zones.
- 2. Check for blockage: Remove any bottles or racks that may obstruct the airflow grille. Ensure vents are not covered.
- 3. Access the fan: Remove the grille or panel to expose the fan. Inspect for broken blades or foreign objects.
- 4. Spin and test: Spin the fan by hand; if stiff, the motor is likely bad. Check wiring and connector for damage.
- 5. Replace fan: Install a new Liebherr circulation fan motor assembly and reassemble the grille.
- 6. Test operation: Restore power and confirm that the fan runs when both zones are cooling.
