rotating glass tray was grinding and not turning.

I first took the filters of the exhaust and then removed the screws on the bottom of the combination microware hood fan. Once the 6 retention phillips head screws were removed from the bottom of the microwave, and the hinged bottom "door" lowered the motor was exposed. I removed the motor by removing the two phillips screws and unplugged the motor. The hardest part was finding a replacement on the net because most shops did not give enough details or pictures to know if a part was exchangable or a replacement. Partselect.com listed the parts, motor voltage, and had pictures so that I was comfortable with ordering. The part arrived the day it was scheduled to and I simple reversed the process and within 5 minutes I had the microwave motor in and back together. It is nice to do business with a place that also gives you a returns policy upfront.
