Upper zone cools but lower zone is warm (on dual-zone models)

Safety first: Unplug the wine cooler before removing internal panels.

Steps:

• Check for airflow: With the unit running (before unplugging), feel for airflow at the lower vents. Weak or no airflow suggests a fan or blockage issue.
• Inspect lower fan: Remove lower shelves and the rear panel to access the lower evaporator and fan. Check for ice, debris, or a seized motor.
• Sensor check: Verify the lower zone sensor is properly mounted and connected.

Repair: Replace a failed lower evaporator fan motor or damaged sensor. If the lower evaporator remains warm while the upper is cold and the compressor runs, a sealed system issue specific to the lower circuit may exist and requires professional service.
