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.
