When a problem occurs with a GE oven, the electronic control panel displays an error code. If the oven keeps flashing a locked door "F9" code, this indicates the door lock circuit needs to be fixed. In some instances, GE oven owners can easily fix it themselves, while in other cases, it's best to contact GE for help.
Reset
When an error code appears on the GE oven display, resetting the appliance can resolve the problem. Disconnect power to the oven for 30 seconds before plugging the oven back in. If the oven is built into an electrical system, shut off the circuit breaker and then wait 30 seconds to reset it. Once power is restored, make a new oven selection to see if the error code returns on the display.

Door Switch
The F9 error usually means the door switch circuit system is faulty. This can be addressed by checking the door switch itself. If the door switch is dirty or caught in one position, use a damp cloth to wipe the switch clean and then wiggle the switch slightly to make sure the switch moves back and forth. Then close the oven door so that the door closes firmly and latches into position.
Circuitry
If resetting the GE oven or cleaning the switch does not resolve the error code, the wiring may need to be replaced. Owners with some skill can unplug the oven and take off the upper back panel by removing the screws on each side and then carefully lifting the panel up and off the range. Examine the wiring to see if any of the wires are damaged or disconnected. Contact GE for assistance when replacing the wiring.
Door Latch Mechanism
Check the latch rod to see whether it raises and lowers correctly. The door latch mechanism is located near the rear of the range on a geared motor connected to a cam. This motor operates the door latch on a rod. If the rod is stuck in position or damaged or broken, contact GE for service.
Tips
If you do not feel comfortable removing the back panel and investigating the wiring or door, do not attempt to disassemble the range. Contact GE for assistance if resetting or cleaning the door switch does not return the door to proper performance. Tell GE that the door switch mechanism or wiring is likely to blame.
