GE Range Error Code F4 E2

F4 E2 means the oven detected a temperature runaway condition during cook mode, where the cavity temperature rose beyond safe limits without being regulated. The control board triggers this fault as a safety measure to stop the oven from overheating. It most commonly points to a bake relay stuck in the closed position, a faulty temperature sensor, or a control board issue.

Resetting the range by cutting power at the breaker may temporarily clear the fault code, but it will return if the underlying cause is not repaired. If the bake relay is welded shut or the temperature sensor is faulty, the runaway condition will happen again as soon as the oven heats up. A reset is only useful as a first step to confirm whether the fault is intermittent.

Repair costs depend on which component has failed. A replacement oven temperature sensor typically runs between $20 and $60 for the part. A new control board or relay board can range from $100 to $300 or more depending on the model. Adding professional labor, total repair costs commonly fall between $150 and $450.

No, you should not use the oven while this fault is active. F4 E2 indicates a temperature runaway condition, which means the oven may not be able to stop heating on its own. Continued use could result in overheating, damage to the appliance, or a fire hazard. Leave the oven off and diagnose the fault before operating it again.

Start by entering diagnostics mode and pressing the BAKE key to cycle the bake relay on and off, confirming whether the relay responds to control commands. If the relay does not cycle, the relay or control board needs replacement. Also test the oven temperature sensor resistance to rule out a faulty probe sending incorrect readings to the board.
