I first took the top panel off to get access to the control panel screw. I then removed the control panel, took pictures of all the wiring and then disconnected it all. I then removed the holder locker, salvaging the middle door switch. I then installed the door switches on the new holder locker, added a new disconnect terminal to one of the wire pairs (it had gotten grease in it somehow and looked to have shorted at one point). Installed the new holder, connected the wires up and then wired up the panel and reinstalled. Plugged in the microwave, hoping that it would not catch on fire and then proceeded to testing.
