Thermador Range Error Code F113

F113 indicates that the upper oven (or single oven) temperature exceeded 950°F, triggering a runaway temperature safety fault. The control system detected dangerously high heat and shut the oven down to prevent damage or fire. The fault involves the temperature sensor, the Power Board, and associated wiring. The oven should not be operated again until the underlying cause is identified and corrected.

No, the oven should not be used while F113 is active. The error indicates the oven temperature exceeded 950°F in an uncontrolled manner, which is a fire hazard and can damage the oven cavity, internal components, and cookware. The oven's control system has shut down the heating circuit as a safety measure. Do not attempt to bypass this fault or continue cooking until repairs are completed.

Repair costs vary depending on which component has failed. A replacement oven temperature sensor typically costs in the range of $30 to $80 for the part. A Power Board replacement is more expensive, generally ranging from $150 to $400 or more for the part alone. Adding professional labor for diagnosis and installation will increase the total cost, often bringing a complete repair into the $200 to $600 range depending on the specific failure and your location.

Some steps are accessible to a knowledgeable DIYer, such as inspecting and reseating the P4 connector on the Power Board and testing the temperature sensor resistance with a multimeter. If the sensor reads roughly 1080 ohms at room temperature, it is likely functioning correctly and the Power Board may need replacement. Replacing the Power Board or tracing damaged wiring inside the range is more involved and may be better suited to a qualified technician.

A reset, such as cycling power at the breaker, may temporarily clear the fault code, but the underlying cause will remain. If the temperature sensor is shorted, the Power Board is faulty, or wiring is damaged, the runaway condition will recur and F113 will return. A reset should only be used as part of the diagnostic process, not as a repair.
