Thermador Codes and What They Mean
Thermador ranges and ovens use GE-style F-codes on the electronic control. The table lists the codes we see most often and what each one points to.
| Code | What It Means | What We Do |
|---|---|---|
F1 | Control board or stuck touch key fault | Reset power; if it returns, test the touch panel and replace the electronic control |
F2 | Oven over-temperature condition | Check the oven temperature sensor and relay board for a stuck-closed relay |
F3 | Open oven temperature sensor circuit | Test the sensor resistance and wiring and replace an open sensor |
F4 | Shorted oven temperature sensor | Replace the shorted sensor and inspect the harness for damage |
F7 | Stuck function key on the control panel | Free or replace the membrane touch panel |
Typical Thermador Faults
- Oven displaying an F-code
- Star burner not igniting
- Column refrigerator not cooling

- Uneven oven baking
How to Avoid Thermador Repairs
Many Thermador problems are preventable. Protect the ranges, cooktops, and column refrigeration by keeping their airflow unobstructed, respond to early warning signs before they spread, and choose Genuine OEM Parts for any fix. These habits do more for reliability than anything else.
