Changing Turntable motor

Repair went smoother than expected, but a couple of comments should be made. The screws are easy to see and to remove from the bottom plate of the Microwave. The inside of the plate, where the light and filter are can be really greasy and icky. The motor was easy to replace. Putting the screws back in can be relatively tough - especially the ones in the back. I lost one. Might be good to be better prepared to make sure that they don't drop behind the counter.
