The microwave was mounted inside a cabinet so I had to take the front surrounding cover off and the mounting brackets.Once I unplugged the power and took the microwave out, the installation of the new motor was easy. I turned the microwave upside down and had to snip some metal pieces on the bottom of the microwave to get the plate off to see the old motor. i slipped the connections off, took out two screws and replaced the motor. The plate went back on easily and the whole job took about 30 minutes.
