Starts by itself. beeps constantly when on. locks up in pan mode

You have a shorting 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.

On many Kitchenaid models, the keypad is not available as a separate part and you have to order the plastic control panel frame / subassembly (depending on model number) which comes with a new keypad.

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.



Some connectors on the relays may have a lock:
