Dacor Range Error Code F10

F10 on a Dacor range signals either a shorted element relay on the power board or a problem with the oven temperature sensor circuit, including an intermittent sensor fault or loose sensor wiring. The control system uses this code to indicate it has detected an abnormal condition in the heating or temperature sensing system. Identifying which of the two causes is present requires inspecting the sensor wiring and testing the sensor before concluding the power board needs replacement.

It is not recommended to continue using the range with an active F10 error. A shorted element relay can cause a heating element to run without control, creating an overheating hazard. Even if the cause is a sensor issue, the oven cannot accurately regulate its temperature in this state, which poses both a safety and food safety risk.

Repair costs vary depending on the cause. Replacing a temperature sensor is typically the less expensive fix, with parts generally ranging from $20 to $80 and modest labor costs if a technician is involved. Replacing the power board is a more significant expense, with board parts commonly ranging from $150 to $400 or more depending on the specific model, plus labor. Getting a diagnosis first helps avoid paying for parts that are not needed.

Some F10 causes are DIY-friendly, particularly tightening or reseating loose sensor wiring connections. If the wiring is secure and the sensor tests faulty, replacing the temperature sensor is also a manageable repair for someone comfortable working with appliances. However, if the shorted relay on the power board is the cause, replacing the power board involves working near high-voltage components and is best handled by a qualified technician.

Disconnecting the range from power for a few minutes may temporarily clear the F10 code, but if the underlying fault is still present, the code will return once the oven is operated again. A reset does not repair a shorted relay or a defective sensor. Clearing the code without addressing the root cause is not a lasting solution.
