GE Range Error Code F0

Open OFF key

GE codesGE range codes

Open OFF key — supervisor jumper, open wire or terminal within keypad harness, or bad solder on crystal mounted keypad board.

First step from the service manual

Check supervisor jumper (there are 2), check for open wire or terminal within keypad harness, inspect solder on crystal mounted keypad board.

What F0 means on a GE range

The F0 error code on a GE range indicates the control board has detected a stuck key on the keypad, a transistor failure on the control board, or an unintended relay activation. These three conditions share the same code because they can produce similar symptoms: a function appears to be running without being commanded, or the control cannot accept input or clear itself. Technicians should first attempt to cancel the code and cycle power. If the code returns immediately or cannot be cleared, the control board is the likely culprit, either due to an internal transistor failure or a relay stuck in the closed position.

For homeowners, F0 typically means the control board thinks a button is being held down when it isn't, or it has triggered a function on its own. This can happen when moisture or grease gets under a keypad button and causes it to register continuously, or when a component on the control board itself fails internally. In some cases, an oven burner or element may turn on without being selected, which is a serious condition. If you cannot cancel the code and the oven is behaving unexpectedly, shut off power to the range at the breaker until the appliance can be serviced.

Common causes of F0

  1. 01

    Stuck or shorted keypad button

    Part replacement

    Food debris, grease, or moisture beneath a keypad button can cause it to register as continuously pressed. The control board reads this as a persistent input and triggers the F0 code.

  2. 02

    Transistor failure on the control board

    Part replacement

    A transistor on the main control board can fail in a shorted state, causing the board to behave as though a command is being sent. This is an internal board failure that cannot be repaired at the component level in the field.

  3. 03

    Relay stuck in closed position on control board

    Part replacement

    A relay on the control board that is stuck closed can activate a burner or oven element without a user command. This condition is indicated in the F0 code definition and requires control board replacement.

Frequently asked questions about F0

What does F0 mean on a GE range?
F0 on a GE range means the control board has detected a stuck keypad button, an internal transistor failure, or a relay that has turned on unintended. The control board cannot distinguish between these three causes and uses one code for all of them. Pressing Cancel will clear it if the cause is temporary, but if the code returns, the control board needs to be replaced.
How do I fix the F0 error code on a GE range?
Start by pressing Cancel or Clear to dismiss the code, then restore power if you cycled the breaker. If the code comes back, inspect the keypad for any buttons that feel sticky or are physically depressed. Clean around the buttons carefully. If cleaning does not resolve it or the code reappears immediately, the control board needs to be replaced, as internal transistor or relay failures cannot be repaired.
Is it safe to use my GE range with an F0 error code showing?
No, using the range with an active F0 code that cannot be cancelled is not safe. Because F0 can indicate a relay stuck in the on position, a heating element or burner could be energized without your input. If the code will not clear after pressing Cancel, shut off the range at the circuit breaker and do not use it until the control board has been replaced.
Can I clear the F0 code on my GE range myself without replacing parts?
Sometimes. If the code is caused by a temporarily stuck keypad button, pressing Cancel or cycling power at the breaker for 30 seconds may clear it. If the code does not return after that, the issue may have been a one-time glitch or a button that is no longer stuck. If the code comes back, a part replacement is required and there is no software reset that will fix a hardware failure on the control board.
How much does it cost to fix an F0 error code on a GE range?
A replacement GE range control board typically costs between $150 and $400 for the part depending on the model. If you hire a technician, expect to add $100 to $200 in labor, bringing the total repair to $250 to $600. DIY replacement is feasible for most homeowners since the control board is accessible behind the back panel or under the console, and requires only basic hand tools. Confirm your model number before ordering a board, as GE uses many different control boards across its range lineup.
