KitchenAid Range Error Code F6 E2

F6 E2 indicates an over-temperature runaway condition detected during the self-clean cycle. The oven's control system determined that the cavity temperature exceeded safe limits and could not be regulated, triggering a protective shutdown. The fault most commonly points to a stuck relay on the control board, a defective oven temperature sensor, or a wiring issue in the temperature sensing circuit.

Disconnecting power to the range will clear the active display of the fault code, but the underlying fault condition will remain. If the stuck relay, sensor failure, or wiring issue is not corrected, the fault will return the next time the oven heats up, and the same thermal runaway risk will be present. A proper repair is required, not just a reset.

Repair costs vary depending on the failed component. A replacement oven temperature sensor typically falls in the range of $20 to $60 for the part alone. A new electronic range control board is significantly more expensive, generally ranging from $150 to $400 or more depending on the model. Adding a technician's labor for diagnosis and installation will increase the total cost, usually bringing the full repair into the range of $200 to $600 depending on the root cause.

You should not attempt to run the self-clean cycle again until the underlying cause has been diagnosed and repaired, as a thermal runaway condition presents a fire hazard. Limited use of surface burners may be possible, but operating the oven in bake or broil mode is not recommended until the relay and sensor circuits have been inspected and confirmed to be functioning correctly.

Diagnosis starts by entering diagnostics mode to verify the stored fault, then using test mode to cycle the bake, broil, and convection relays individually while checking for 120V at connector P6 pins 1 through 5. If a relay is stuck on, the control board typically needs replacement. If relay operation is normal, the oven temperature sensor and its wiring should be tested next. A qualified technician should perform these checks given the high-voltage and high-temperature components involved.
