GE Range Error Code F1x

The F1x code on a GE range means the oven cavity temperature has exceeded 665°F while the door is in the unlocked position, triggering a thermal protection fault. The control board detected a runaway heating condition and shut down oven operation as a safety measure. The most likely causes are welded relay contacts on the control board or high resistance in the temperature sensor wiring connectors.

Resetting the range by cutting power at the breaker or unplugging it may temporarily clear the F1x code, but it will return if the underlying cause is not corrected. If welded relay contacts are causing continuous element heating, the fault will recur as soon as the oven heats up again. A reset is useful for confirming whether the fault is intermittent, but it is not a repair.

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 new electronic control board is the more expensive repair, with parts generally ranging from $100 to $300 or more depending on the model. Adding professional labor can bring total repair costs to anywhere from $150 to $450 or higher, so getting a diagnostic estimate before committing to repairs is advisable.

No, you should not use the oven while this error is active. The F1x code indicates the oven may be heating beyond its intended safe temperature range, which poses a risk of damage to the appliance and a potential fire hazard. Disconnect power to the range until the fault has been properly diagnosed and repaired.

Start by inspecting the relay contacts on the oven control board for signs of welding or carbon scoring, as a stuck relay is a primary cause of this fault. Next, check the resistance in the oven temperature sensor connectors, particularly at the rear connector closest to the sensor probe, looking for corrosion or loose pins. Depending on findings, the repair may involve replacing the control board, cleaning or replacing wiring connectors, or replacing the temperature sensor itself.
