Kenmore Range Error Code F4 E2

F4 E2 on a Kenmore range means the oven experienced a temperature runaway condition during a cook cycle. The oven temperature climbed beyond its safe operating limit and could not be controlled properly. The range shuts itself off when this happens to prevent damage or a fire hazard. The most common cause is a bake relay with welded contacts that keeps the heating element powered continuously.

Disconnecting power to the range may temporarily clear the F4 E2 code, but the underlying fault will almost certainly return once the oven is used again. If the bake relay contacts are welded or the temperature sensor is defective, those conditions have not changed after a reset. A reset alone is not a repair and should not be treated as a solution.

Repair costs depend on which component has failed. A replacement oven temperature sensor typically runs in the range of $20 to $60 for the part. A new oven control board is more expensive, generally ranging from $100 to $300 or more depending on the model. If you hire a technician, expect to add $75 to $150 or more in labor costs on top of parts, though some repair shops charge a flat diagnostic fee.

No, it is not safe to continue using the oven when this code is active. F4 E2 indicates the oven lost temperature control during cooking, which means the oven could overheat again if another bake cycle is attempted. The range should remain out of service until the faulty component, whether a relay, sensor, or control board, has been identified and replaced.

Start by entering the range's diagnostic mode and pressing the BAKE key to test whether the bake relay cycles on and off correctly. If the relay does not respond properly, the control board or its relay will need to be replaced. If the relay cycles correctly, check the oven temperature sensor's resistance to determine whether it is reading accurately. Resolving the fault requires replacing whichever component, the control board, the relay, or the sensor, is found to be outside its correct operating parameters.
