Display shows F2 and the wine cooler may run continuously or shut down cooling; temperature readings are inaccurate.

Safety first: Disconnect the appliance from mains power before accessing internal components. Sharp metal edges may be present around the evaporator area.

F2 typically points to a problem with the evaporator temperature sensor that monitors coil temperature for defrost and compressor control.

• 1. Access the evaporator area:
  • Remove wine shelves and interior panels at the back of the compartment to expose the evaporator cover.
  • Carefully remove the evaporator cover (often held by screws and clips). Do not force it; hidden clips can break.
• 2. Locate the evaporator sensor:
  • Find the small sensor clipped or strapped to the evaporator tubing or embedded in the evaporator fins.
  • Check that it is firmly attached and not hanging loose.
• 3. Inspect wiring:
  • Follow the sensor wires to the cabinet pass-through and down to the control board.
  • Look for chafed insulation, ice damage, or broken wires.
• 4. Test the sensor:
  • With power off, disconnect the sensor from the board.
  • Measure resistance at room temperature and compare to typical NTC values. An open or shorted reading indicates failure.
• 5. Replace the evaporator sensor if defective:
  • Order the correct Miele evaporator NTC sensor for your model.
  • Install it in the same position and secure it tightly to the evaporator for accurate readings.
• 6. Clear ice buildup: If the sensor was encased in ice, allow the evaporator to fully defrost (leave unplugged with doors open and towels in place) before reassembly.
• 7. If the sensor and wiring test good: The main control board may be faulty and should be evaluated or replaced by a professional.
