Short answer: Thermador shares the BSH control platform, so ovens and dishwashers report E and F codes for sensor, heating, and drainage faults. Star burners and induction cooktops fail at igniters and coils. The code narrows it; we confirm with meters.
Ovens and Ranges
Thermador ovens report fault codes tied to the temperature sensor, heating circuit, and door-lock system. A cavity that will not heat is usually an element or relay; one that runs off-temperature is a drifted sensor. Pro-range star burners fail at the igniter, much like other sealed burners.
Cooktops
Thermador induction and gas cooktops drop a zone or burner from a coil, control, or igniter fault. Freedom induction tops are diagnosed at the control and coil level. We test rather than swap boards on a guess.
Refrigeration
Thermador built-in refrigeration, which shares much with the BSH group, fails at fans, defrost parts, and controls when it warms. Airflow and defrost come before the sealed system in our diagnosis.
Error & Symptom Reference
| Area | Common Fault | Fix |
|---|---|---|
| Oven no heat | Element or relay | Test circuit, replace part |
| Oven off-temp | Temperature sensor | Test/replace sensor |
| Burner no light | Igniter | Clean/replace igniter |
| Induction zone out | Coil or control | Test and replace |
| Refrigerator warm | Fan/defrost | Restore airflow, service defrost |
A Note on Parts and Safety
Testing beats guessing here, because a Thermador fault often traces back to more than one possible cause. Our technician isolates the circuit on the Thermador unit, tests the suspect parts, and replaces only what has actually failed. Before the visit, note when the symptom started and what the unit was doing, which shortens the diagnosis. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.
