Motor Burned Out On Turntable
My 8 year old daughter cleaned the inside of the microwave with enough water to rival a tsunami. Resulted in a clean microwave with a fried out motor that no longer revolved. Part came quickly. Took cover and bottom off to get to the part. One screw held it on and a plug. Removed those, put on new part and she was good to go. No trip to home depot today.

One of the switches in a component that door activates when shut.
I replaced the whole component with all three switches in it even though only one switch was bad . Taking out one switch out of the holder unit would probably have damaged the unit that was holding the switches. Easy install and it works great again .

would not start.
diagnosed defective 'door-shut switch' in the switch holder assembly. rather than replace switch, replaced entire locker holder assembly which made for a very simple and easy repair...not to mention very inexpensive.
