Display shows F7 and the wine cooler may not respond correctly to door opening; interior light or fan behavior is abnormal.

Safety first: Disconnect power before removing trims or panels around the door frame.

F7 indicates the control is not receiving a valid signal from the door contact system.

• 1. Check door operation:
  • Open and close the door while watching the interior light and display. If they do not change state, suspect the door switch.
• 2. Locate the door contact:
  • Miele wine coolers often use a magnetic reed switch in the cabinet frame and a magnet in the door.
  • Identify the switch location (usually along the top or side frame) and the corresponding magnet in the door gasket area.
• 3. Inspect alignment:
  • Ensure the door closes fully and the magnet aligns with the switch area.
  • Adjust door hinges if the door is sagging or not sealing properly.
• 4. Test the switch:
  • With power off, remove the trim to access the reed switch.
  • Disconnect the switch and test continuity with a magnet applied and removed. It should open and close reliably.
• 5. Replace faulty components:
  • If the reed switch does not change state, replace it with the correct Miele door contact switch.
  • If the magnet is missing or cracked, replace the door magnet insert.
• 6. Wiring and board:
  • Check wiring from the switch to the control board for breaks.
  • If wiring and switch are good but F7 persists, the main control board input may be defective and should be replaced by a technician.
