Thermador Oven Temperature Sensor Fault Symptoms

A failing temperature sensor shows up as inconsistent baking or a temperature fault, since the control reads the RTD probe as open or out of range. The most common cause is the RTD probe reading open, shorted, or out of range.

Checking for an obvious cause you can see, like a visibly broken element, or confirming the breaker, is safe to try — confirming a sensor or control board fault requires testing with a meter.

If it’s still reaching temperature and cooking normally, short-term yes — but don’t wait too long, since heating faults tend to worsen.

Not always — it could be a sensor, heating element, or igniter, which is exactly what the diagnostic visit determines.

It varies by which component is involved, confirmed in writing after the on-site diagnostic.

Once diagnosed, most are same-visit repairs.
