After the sticker shock of how much a replacement over the range microwave my boyfriend suggested we try to fix the microwave before replacing it. We found the thermostat had melted. Appliance parts pros' website was easy to use. I loved the guarantee that this was the correct part and they were cheaper than the manufacturing company website! The part works perfectly! My microwave is as good as new for a fraction of the cost! Highly recommend their website! And I love that they have a chat option if you have any questions before you purchase.
