F9 is a Door Latch/Lock problem.
It is looking at the switches and is not getting the correct feed back.

Found a couple things to try:

1. Press and hold the door latch handle in the unlocked position and press Cancel for a few seconds.

2. Push the door interlock switch. Hold for 20 to 30 seconds. Should hear the door latch go to the unlock position. Release the switch. Turn oven to 350 for one minute and see if the error will clear.

Am not sure either of the above will work but worth a try.

Check for loose wires going to and at the door latch switches.
Check the switches with a meter.
