Thermador dF error code

The unit isn’t defrosting properly or the evaporator fan has stalled, so frost builds and cooling drops — we test the defrost heater, sensor and fan.

Because a code points to a likely area rather than an exact part, we run a full on-site diagnosis to confirm the real cause — testing the components above and the wiring and controls behind them. You get a clear, flat-rate quote before any work begins, and most dF faults are resolved on the first visit with quality parts and a parts-and-labor warranty.
