Unplugged unit from wall. Removed top trim piece of wall-mounted microwave oven. Removed Phillips head screw to detach control panel. Unplugged connections to microswitches for door latches and turntable motor. Swapped out new parts and reassembled microwave. Plugged unit back in and it worked like new! Probably saved over $1K by not having to buy a new over the stove, wall-mount microwave oven!
