F3 – Oven error code

Thermador Oven error code

F3 is an error code the Oven uses to flag a condition the owner manual groups with controls, heating, water, or airflow. The same characters can mean different branches on different revisions, so the rating plate matters as much as the display.

If the code appears with clicking from the valve or fan area, note timing and frequency—mechanical and electrical causes read differently on site.

FAQ

Process, pricing, and what to expect during your visit.

Intermittent faults often involve sensors, fans, or control logic that fails only at temperature. Log when the code appears (preheat, broil, convection) and call if repeats affect meals.

Charts vary by series and software. The characters on the glass are a starting point—model and serial map them to the correct branch in the manual.
