Thermador Hi error code

The cabinet is warmer than its setpoint — causes range from a door left ajar to a sealed-system or fan fault, which we diagnose.

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