What Does Error Code F3 Mean on a Miele Refrigerator?
Freezer compartment air sensor fault.
F3 fires when the freezer compartment's air-temperature NTC thermistor reports a value outside the control's plausible range — typically an open or short circuit reading, or a resistance the board can't reconcile with normal operation. The control loses trusted feedback for the freezer and switches to a fixed fallback compressor cycle. It's distinguished from the fridge-side sensor codes (F1/F2) by which compartment reports the fault, and from evaporator or defrost sensor faults handled under separate codes.
