The circuit board is bad that controls it. try unplugging and waiting and plug it back up and see if that resets, if not I would take it in for repairs

A few possibilities pop out at me: Could be a door switch or the thermal fuse monitoring the mag tube's temperature. Time for a service technician to look at it, or, if it were me, I'd just buy a new microwave.

I surmise there's a short in the Quick Defrost button on the keypad. Either the keypad has collapsed there, or some contamination has gotten in. Another possibility is a failing program memory bit in the controller chip, but a contaminated keypad seems most likely. What happens if you press and hold that button while trying to key in another instruction? Is there any change in behavior?

It sounds like the hinges are worn out or broken. Probably cheaper to buy a new one that to fix the old one.
