Lower zone cools properly but upper zone is warm.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Upper zone evaporator fan failure, Blocked upper air vents, Faulty upper zone temperature sensor, Diverter damper stuck closed (on some models)

Safety: Unplug the cooler before working inside.

Check vents: Make sure bottles are not blocking the upper zone air outlets.
Listen for fan: With the unit running, listen for airflow in the upper zone. If none, suspect the fan.
Access upper fan: Remove upper shelves and interior rear panel to reach the fan assembly.
Inspect and test: Check for ice, debris, and test the fan motor with a multimeter. Replace if open.
Check sensor: Verify the upper zone sensor is properly mounted and not damaged; replace if readings are incorrect.
