Larry C Lusby , MD March 24, 2015 The rotating ring on the micro wave had a broken wheel We got on the internet and looked at Appliance Pros.com. We put in the part no for our unit and they matched it right up. It was not a difficult repair and replace because all you had to do was to take the unit out from inside the microwave unit and put the new one in. What was remarkable was the speed of delivery, it happened fast and correctly. 24 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
