LG double oven shows f9 code in both ovens

An F9 error code on a General Electric (GE) oven indicates that the oven's electronic control system has detected a problem with the automatic door lock. The automatic door lock mechanism prevents the oven door from being opened when the oven is set for "Clean" mode. The malfunction may be a jammed door lock mechanism, a pinched or broken wire, a faulty lock switch or a fault in the control board itself

F9 is a problem with the oven door lock circuit. If the door is locked, it's probably a bad switch that tells the oven it's locked. If the door isn't locked, it's probably a problem with the lock mechanism.

A common problem on many built-in GE ovens (you don't say if yours is built-in or free standing...) is air circulation in the control panel. The fan that keeps the panel cool either stops working or gets clogged with dirt/dust and can't move any air. This causes the panel to overheat and can cause all kinds of odd problems and error codes. If you have a built-in, check to make sure the fan is working and the mesh screen behind it is clean.

See service manual or contact manufacturer.

F9 code is a door latch error code. Either the latch motor or latch didn't get reset. Check the wiring to the latch motor and make sure everything is connected. Also try flipping the breaker and leaving it off for five or ten minutes, see if it might reset itself. If that doesn't work, you can have a latch motor gone bad, a harness issue, or possibly an electronic board that has shorted during the cleaning or operation programs.

had F19 error code on lower oven, F9 on upper. Pulled stove out and turned the regulator switch ON. Worked instantly. I thought I had the regulator on because the stovetop worked. The stovetop regulator is separate from the main regulator!!

Failure to clean code
I have two Monogram ovens but they are not adjacent to each other top and bottom but are separate in different areas of the counter. I did the self clean for both ovens for the first time and one oven had the F9 error code about 1 hour and 45 min into the clean and the other did not sound a code.

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

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.

oven door will not close tight - what is wrong

The F9 error message usually means that the oven temperature is above 600 degrees F. Check that the fan is operating. Make sure that it is not blocked. Make sure the vent areas are not blocked. There could also be a welded relay contact or high resistance in the oven sensor leads or connections.
