Bosch Range Error Code F10

F10 on a Bosch range indicates a runaway temperature condition. The control board has detected that the oven temperature sensor is reporting abnormally high resistance values, which typically means the oven is overheating. This often happens when a heating element fails to shut off due to a stuck relay on the control board, but a faulty sensor can also trigger the code without genuine overheating.

Resetting the range by cutting power may temporarily clear the F10 code, but if the underlying cause is a stuck relay on the control board or a defective temperature sensor, the error will return and the oven may continue to overheat. A reset should only be used as part of the diagnostic process, not as a fix.

Repair costs depend on which component has failed. Replacing an oven temperature sensor is typically the lower-cost option, with parts generally ranging from $20 to $80 and labor adding more if a technician is involved. Replacing the control module is more expensive, with parts alone often ranging from $150 to $400 or more depending on the model, plus labor costs.

No, you should not continue using the oven when F10 is active. A runaway temperature condition can indicate that the heating element is not shutting off, which is a fire hazard. Disconnect power to the range immediately and do not restore power until the root cause has been diagnosed and repaired.

Start by inspecting the oven temperature sensor probe and its wiring harness for damage or corrosion, and replace them if any issues are found. If the oven is confirmed to be overheating, disconnect power immediately. When power is restored, if the oven continues to overheat, the control module needs to be replaced, as it likely contains a relay that is stuck in the closed position.
