GE Oven Error Code F0

The F0 code on a GE oven indicates that the oven exceeded a safe temperature limit or that a transistor inside the control board has failed. Specifically, the code triggers if the oven surpasses 590°F with the door unlocked, or 990°F with the door locked during a self-clean cycle. It can also appear due to an internal electronic fault in the control board even without an actual temperature spike. Both conditions require diagnostic attention before the oven is used again.

In some cases, pressing the Cancel key or cutting power at the breaker and restoring it will clear the F0 code if the over-temperature condition has resolved on its own. However, if the code returns or cannot be canceled, that is a strong indicator of a welded relay or a failed transistor in the control board, both of which require physical repair or part replacement.

Repair costs depend on which component has failed. A replacement oven control board typically runs between $150 and $350 for the part alone, with additional labor costs if a technician is performing the repair. If only a relay is faulty and the board can be serviced at the component level, costs may be lower. Diagnostic fees from a service technician generally range from $75 to $150 and are sometimes applied toward the total repair cost.

No, you should not use the oven while F0 is active. A welded relay contact can cause the heating element to run continuously without control, which is a fire risk. Power the oven off at the circuit breaker until the cause of the fault has been identified and corrected.

Start by checking whether the oven actually overheated, particularly if the fault appeared during or after a self-clean cycle. Test the relay operation on the control board and look for welded contacts that prevent the relay from opening. If no relay fault is found, the control board itself likely has a failed transistor and will need to be replaced. A qualified technician can test these components and confirm which part is responsible.
