Unplug your microwave. Took the screws off of the bottom of the unit with it still on the cabinet. The whole bottom panel swung down to expose the turntable motor. I took the power cable loose (just pull it off). It was one screw to take the motor out. Word to the wise: DON'T try to take the plastic coupler off before the motor. Their is a tab that holds it in while the motor is in place. If you pry it up you will break it, trust me. ;) Turn the motor out of its housing and it come right out. You can use a volt meter to test if you unit is providing voltage. Mine was and I could not turn the motor so I figured it was just a bad motor. Put in the new motor the same way it came out. Tested it - SUCCESS! Put it all back together, batta boom, mamas got a working turntable.
