I diagnosed the problem via YouTube, the rotating motor was bad. The repair seemed simple and part easy to find on the ApplianePartsPros.com website. Removed the old motor and found a replaceent on your site, and ordered it. The part showed up in 2 days. The repair was simple to replace the bad motor with a new motor. It was 2 screwes and 2 wiring harnesses, very simple. The repair was successful. It took all of 5 minutes to do the entire repair and put the microwave back together. Very pleased with how quickly the new motor arrived.
