GE Range Error Code F4 E3

F4 E3 indicates an over-temperature condition during the self-clean cycle, also called temperature runaway. The oven's temperature climbed beyond the safe upper limit and the control board could not regulate it back down. The range shuts down as a safety measure when this fault is detected. The most common culprits are a stuck bake relay on the control board or a faulty oven temperature sensor.

Resetting the range by cutting power at the breaker may temporarily clear the code, but it will not fix the underlying problem. If the bake relay is stuck, the temperature sensor is faulty, or the control board has failed, the fault will return the next time the self-clean cycle is used. A proper repair requires diagnosing and replacing the defective component.

Repair costs vary depending on which component has failed. A replacement oven temperature sensor typically runs in the range of $20 to $60 for the part alone. A control board replacement is more expensive, generally ranging from $150 to $350 or more for the part, with additional labor costs if a technician is hired. Getting a diagnostic visit from a repair technician can help confirm the faulty part before committing to a repair.

You should not resume using the self-clean cycle until the fault has been diagnosed and repaired. A temperature runaway condition means the oven cannot reliably regulate heat, which poses a fire and damage risk. Regular baking at lower temperatures may be possible in some cases, but the underlying cause should be identified by a technician before further use.

Start by entering diagnostics mode and pressing the BAKE key to cycle the bake relay on and off. If the relay does not respond, the control board is the likely cause. If the relay operates correctly, test the oven temperature sensor with a multimeter to verify it is sending accurate resistance readings. Depending on the failed component, the repair will involve replacing the control board, the temperature sensor, or the bake element.
