Wine cooler cools but temperature is uneven; top is warmer than bottom or vice versa.

Safety: Unplug the unit before removing interior panels or fans.

• Check fan operation: With the door closed and unit running, listen for the internal fan. If silent, inspect and replace the Grundig evaporator fan motor if necessary.
• Inspect vents: Ensure that air outlets and inlets on the rear or sides inside the cabinet are not blocked by bottles or shelves.
• Clean ducts: Remove the rear interior panel and clear any dust or ice from air channels.
• Check dual-zone partition: On dual-zone models, inspect the partition and seals between zones. Replace any damaged zone partition gasket to prevent air mixing.
