Miele Refrigerator Error Code F3
Freezer compartment air sensor fault
The air-temperature sensor in the freezer compartment is returning an implausible value. The control can't verify the freezer is holding temperature, so it runs a fallback program. Food safety is the practical risk — the display can no longer be trusted to reflect real freezer temperature.
