My LG Double gas oven model # LDG3036BD upper oven is not heating. I get error code F9.

Check to be sure your racks are all slid in to the back. Are you getting a error code?

Was able to get the lock to go in on the door and then turned off the power which reset the system.

I had the same problem today. After I cleaned my self cleaning oven the cycle went back to normal but the oven door would not open even though the screen was clear and didn't read locked. I held the stop button for 3 second, I don't remember what the message said on the screen but I held the stop button in again for 3 seconds and the screen said locked then I did it again and the screen said door and the oven opened. I don't know, maybe it was just sheer luck it's worth a try. I'm happy.

This is a lock switch error code. Check wiring to door lock switch (the wire harness may be connected wrong). Check for stuck lock switch. If the switch cannot be re adjusted, it must be replaced.

Hi

Thanks for using FixYa. F9 error in your oven/range indicates an issue with the door locks assembly and/or the door latch. To start with check the door lock circuit, you can also try to jump start it to see if it's working. If it's not working then the Electronic Range control has gone bad and should be replaced, if it is working then the door lock circuit should be replaced. Please do rate the solution if the issue is resolved or post a comment for further assistance.

Thanks
