Thermador Range Error Code F22

F22 on a Thermador range means the upper oven cancel key has been detected in a shorted low condition, or that the touch panel push buttons are not working correctly. The fault points to the interface between the control display PCB and the touch panel assembly. It can result from wiring connection problems, a failed touch panel, or a faulty PCB.

An F22 fault means push button inputs, including the cancel key, may not respond reliably. This makes it unsafe to operate the oven because you may not be able to cancel a cooking cycle or adjust settings when needed. The range should not be used until the fault is diagnosed and resolved.

Power cycling the range by shutting off the circuit breaker for a few minutes may temporarily clear the F22 code, but if the underlying fault in the touch panel or PCB connection persists, the error will return. A reset is useful for confirming whether the fault is intermittent, but it does not fix the root cause. A proper diagnostic inspection of the connections and components is needed for a lasting repair.

A knowledgeable DIYer can start by checking and reseating the connectors between the control display PCB and the touch panel, which sometimes resolves the fault without parts. However, if the touch panel membrane or the PCB itself has failed, those components need to be replaced, and working inside a range near electrical components carries risk. Calling a qualified appliance technician is advisable if the connection check does not clear the code.

Repair costs depend on which component has failed. If only the wiring connections need reseating, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing a touch panel or control display PCB on a Thermador range can add $150 to $500 or more in parts, plus labor. Replacing both components at once will increase the total cost further.
