See the attachment for a wiring diagram. It is for a JGS8750C but should be close if not the same as yours.
Sounds like the control board is toast either the broil element control relay’s contacts are welded together or the electronics is keeping the relay energized.
The F2 error is usually an over temperature error which would make sense as the broil element is always on.
