I looked on Youtube and found some videos that indicated what the problem might be, the most common was a worn out turntable motor. I took a gamble that the motor was my problem, took the machine apart and saw that it was a fairly easy repair, and ordered the part from AppliancePartsPros.com. The part came within a couple of days, I installed it, and voila! My turntable now works. Great service, prompt delivery. Thank you.
