How to Fix / Troubleshooting
Safety: Unplug the wine cooler before removing interior panels.
- Check air circulation: Ensure vents between zones are not blocked by bottles or shelves.
- Listen for fan: When the lower zone calls for cooling, listen for the lower zone evaporator fan. If silent, access and test the fan motor.
- Inspect lower thermistor: Verify the lower zone thermistor is properly mounted and test its resistance. Replace if faulty.
- Secondary board: If the fan and thermistor are good, the secondary control board for the lower zone may be defective and require replacement.
