F3 on a GE / Hotpoint
microwave means you have a shorted membrane keypad.
If and when an oven is coming on or doing anything by
itself, this is very dangerous and can result in a fire.
So until it is repaired,
please leave it unplugged or leave the door
open when it's not in use, and of course one should never leave a microwave unattended while cooking.
The easiest and quickest way to repair this yourself (it's easy) is to order a new control panel frame, which comes with a new keypad.
It's part # WB07X10959 and you can get it for $92.50 plus shipping here.
You can also find helpful exploded view diagrams at that link.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
Then you unplug the keypad (as per the photo below) and move the circuit board into your frame.
