Refrigerator compartment warm while freezer is cold, no error code displayed

Safety first: Unplug the refrigerator before removing interior panels.

Steps:

• 1. Check loading: Ensure tall containers or packages are not blocking the cold air outlets in the refrigerator compartment.
• 2. Listen for fan operation: With the door switch held closed (for testing only), listen for the evaporator fan running. If silent, see fan motor faults.
• 3. Locate air damper: On many V-ZUG models, the damper is in the rear or side wall of the refrigerator, where cold air enters from the freezer.
• 4. Inspect for ice blockage: Remove the damper cover and check for ice or debris preventing movement. Defrost any ice with gentle warm air.
• 5. Test damper movement: Manually move the damper flap (if accessible). If it is jammed or the motor does not respond to temperature changes, the damper assembly may be faulty.
• 6. Replace damper assembly: Install the correct V-ZUG air damper/mixing flap assembly, reconnect wiring, and reassemble covers.

Warning: Do not force plastic parts in cold conditions; they can crack easily.
