What Does Error F20 Mean?

The Miele refrigerator error F20 signifies a cooling failure, typically resulting from compressor issues or a faulty temperature sensor. This error is often accompanied by a high temperature alarm, inconsistent cooling, and unusual humming sounds. If the internal temperature rises above expected levels, it can jeopardize food safety, requiring prompt attention to restore proper function.

Common Symptoms:

  • Alarm tone or visual alarm with F20 displayed
  • Refrigerator or freezer temperature too warm
  • Possible failure to maintain set temperature

Possible Causes

  • Cooling system malfunction leading to high internal temperature (medium)
  • Door seal or door closure problem allowing warm air ingress (medium)
  • Evaporator fan or airflow failure affecting cooling distribution (medium)

  1. Ensure doors and drawers are fully closed and not obstructed
  2. Check that door gaskets are clean and sealing correctly
  3. Listen for compressor and fan operation
  4. Allow the unit several hours to recover if recently opened frequently or heavily loaded

Technician Only Diagnose and repair cooling system components

  1. Measure compartment temperatures and confirm high temperature fault persists
  2. Inspect evaporator fan, condenser, and airflow pathways
  3. Test compressor operation and refrigerant pressures
  4. Check for sealed system faults or refrigerant leaks
  5. Replace faulty components as identified

Parts needed: Evaporator fan motor, Door gasket/seal, Temperature sensors, Compressor or refrigerant components if necessary
