KitchenAid Oven Error Code F104

F104 indicates that Coil 1/2 has exceeded its safe operating temperature and the oven has shut down to prevent damage. The control system monitors coil temperatures continuously through dedicated sensors, and this code triggers when the thermal threshold is crossed. The initial diagnostic step involves switching off all loads except the IPC power relay and checking the cooling fan and door lock operation. The oven should not be operated again until the root cause is identified and corrected.

No, you should not attempt to use the oven while F104 is active. The error indicates a coil overheating condition, and continued operation could damage internal components or create a fire hazard. The oven's control system has shut down loads specifically to protect the appliance, and that protection should not be bypassed until the fault is fully resolved.

Repair costs vary depending on the failed component. Cooling fan motor replacements typically range from around $100 to $250 including parts and labor. A temperature sensor replacement is generally less expensive, often in the $75 to $175 range. Control board or IPC relay replacements are more involved and can range from $200 to $450 or higher depending on parts availability and labor rates. Getting a diagnostic estimate from a certified technician before authorizing repairs is strongly recommended.

Some basic checks, such as inspecting the cooling fan for obstructions or cleaning blocked vents, can be performed by a knowledgeable DIYer. However, diagnosing and replacing components like the IPC power relay, control board, temperature sensor, or coil assembly typically requires electrical testing tools and familiarity with oven disassembly. If you are not comfortable working with high-voltage appliance components, a qualified technician should handle the repair.

A power reset may temporarily clear the F104 code, but the error will return if the underlying cause has not been corrected. If the cooling fan is failing, the airflow is blocked, or a sensor is defective, the coil will overheat again under normal operation and retrigger the fault. A reset should only be used as part of a diagnostic process, not as a substitute for an actual repair.
