The F3 means you have a shorting membrane keypad.

If and when an oven exhibits this code or is coming on or doing anything by itself, this is very dangerous and can result in a fire.

None of us on this site recommend trying to repair this type of problem on a microwave because it can kill you.  Toss it and get a new one, PLEASE.
