Thermador C1 error code

The compressor or its inverter board isn’t running correctly — the core of a no-cooling fault, which we test.

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 C1 faults are resolved on the first visit with quality parts and a parts-and-labor warranty.
