GE Oven Error Code F4

F4 on a GE oven means the Electronic Range Control has detected an open or shorted condition in the oven temperature sensor circuit. It can also trigger if the door lock switch loses continuity while the oven is above 624°F, which most commonly occurs during a self-clean cycle. The oven stops normal operation when this code appears to prevent unsafe temperature conditions.

No, you should not continue using the oven while F4 is active. The code indicates the control board cannot accurately read the oven temperature, which means it cannot regulate heat properly. Operating the oven in this condition creates a risk of overheating and potential damage to the appliance or surrounding cabinetry.

Repair cost depends on the root cause. If the fix involves only reforming connector terminals or reflowing solder joints, your cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing the oven temperature sensor generally costs $20 to $60 for the part, plus labor. If the ERC board itself requires replacement, parts alone can range from $150 to $350 or more, making professional diagnosis worthwhile before committing to that repair.

In some cases, yes. The most common cause is degraded contact pressure in the J4 connector block on the ERC, which can be corrected by removing the terminals and reforming them to restore a solid connection. You should also inspect the solder joints on the back of the ERC board for cracking. However, if the sensor itself measures outside of approximately 1100 ohms at room temperature, the sensor will need to be replaced.

A reset, such as cutting power at the breaker for a few minutes, may temporarily clear the code, but it will return if the underlying fault is not repaired. F4 can be intermittent, particularly when the root cause is a loose connector terminal or a solder joint that only loses contact under certain thermal conditions. Clearing the code without diagnosing the cause is not a lasting fix.
