I did an initial search online. I have a KitchenAid microwave. All of my searches came up with Whirlpool, so It created some confusion. I stumbled on AppliancePartsPros. I called and I spoke to Michael. He explains that basically, Whirlpool bought everyone up. He confirmed that I had the same part on my screen as what he showed. I went ahead and placed my order with him over the phone, and I had a couple of other basic questions. I expected to have my part maybe in the middle of the next week. I called on a Thursday. I was shocked to see that my part was expected the next day. Indeed, it came fairly early in the day, and it took me maybe 30 minutes to install the new motor. The longest part of that was getting the screws to line up properly on the cover I had to take off. My microwave is working now. Thank you Michael!
