Possible Causes
Failed air damper between zones stuck open, Partition insulation damaged, Single evaporator fan not distributing air correctly, Control board not actuating damper
How to Fix / Troubleshooting
Safety: Unplug the appliance before removing internal panels.
- Check actual temperatures: Use thermometers in both zones to confirm they are equal.
- Inspect partition: Remove shelves and panels to access the partition between zones. Look for gaps or missing insulation.
- Check damper operation: If equipped, observe the Grundig zone air damper while changing setpoints. It should move to adjust airflow. If stuck, clean or replace it.
- Verify fan operation: Ensure the evaporator fan runs properly to allow correct distribution.
- Replace faulty damper or PCB: If the damper does not receive power or respond, the actuator or main PCB may need replacement.
