Display shows F15 and one temperature zone shows dashes or cannot display a valid temperature.

Safety first: Disconnect power before removing interior panels or accessing wiring.

F15 indicates a temperature sensor fault in one of the wine cooler’s zones.

• 1. Determine which zone is affected:
  • Check which zone shows dashes or abnormal readings.
• 2. Locate the zone sensor:
  • Find the small sensor cover on the wall of the affected zone.
  • Remove the cover to access the NTC sensor.
• 3. Inspect and test:
  • Check the sensor and wiring for damage or moisture.
  • Disconnect and measure resistance at room temperature; open or shorted readings indicate failure.
• 4. Replace the sensor:
  • Order the correct Miele zone temperature sensor for your model and zone.
  • Install in the same location and route wiring as original.
• 5. Check connectors at control board:
  • Reseat the zone sensor connector on the main PCB.
• 6. If F15 remains with a new sensor: The control board’s sensor channel may be defective and should be replaced by a professional.
