Display shows F14 and the unit may not maintain separate temperatures in dual-zone models; one zone may be disabled.

Safety first: Unplug the wine cooler before removing interior panels or working near moving actuators.

F14 is associated with the air flap or damper that controls airflow between temperature zones in Miele multi-zone wine coolers.

• 1. Identify affected zone:
  • Note which zone is not reaching set temperature or shows the error.
• 2. Access the air flap:
  • Remove shelves and interior panels between the zones or at the rear wall where the air duct is located.
  • Locate the flap actuator motor and damper assembly.
• 3. Check for obstructions:
  • Ensure no bottles or shelves are pressing against the duct or flap area.
  • Look for ice buildup around the damper and defrost if necessary.
• 4. Inspect actuator and linkage:
  • Check that the flap moves freely by hand (with power off).
  • Look for broken plastic arms or gears.
• 5. Electrical test:
  • Verify that the actuator receives voltage when the control attempts to move the flap (requires multimeter and care; recommended for experienced users).
• 6. Replace faulty actuator:
  • If the motor is seized or the position sensor is faulty, replace the air flap actuator with the correct Miele part.
• 7. If mechanical parts are fine but F14 persists: The control board output or feedback circuit may be defective; contact a technician.
