Our microwave oven turntable would not turn

My Repair & Advice
We bought this microwave second-hand for $15. The original owner apparently donated it to a thrift shop because the turntable stopped working. Trouble shooting was fairly easy.
By opening the access door under the microwave, I was able to easily remove the turntable drive motor. (I had to break the access plate loose from the stamped frame by prying lightly with a screwdriver, since it had not been removed previously). The motor came loose from the microwave by removing a sheet metal screw and turning the motor to disengage its flange from the frame.
By briefly cycling the microwave with the motor turned on, I could easily inspect that the drive shaft was turning. However, the fitting that engages the turntable was stripped and stayed stationary.
Since the fitting could not be ordered separately, I ordered and installed the motor assembly. Switching the plug from the old to the new motor, and reinstalling in the frame took about 10 minutes, including looking for a sheet metal screw to secure the access door. The microwave now works perfectly.
