Dryer would not heat, drying cycle never stopped

Our dryer suddenly stopped heating up, and subsequently would not dry any clothes! The timer would run down to 0, but the dryer would continue to tumble until we manually stopped it. After finding the partselect.com site and checking the 'Parts that Fix' page for our dryer model, I followed the excellent video walkthrough, removed and tested the Thermal Fuse which, sure enough, was bad. I ordered a new fuse and it was delivered two days later (standard shipping). Placing the new Thermal Fuse was simple and I had the dryer running again very quickly, and while it would now stop at the end of the cycle, it was not fully heating up and drying still. I ordered the Cycling Thermostat (next most likely cause, according to the site) and again two days later had it in hand, replaced, and the dryer works perfectly! In the end, our problem was both a bad Thermal Fuse and faulty Cycling Thermostat. The PartSelect site was a perfect tool to not only find the part, but recommend which was most likely to solve the problem, show diagrams of the part locations, and give an excellent video walkthrough of replacing the parts. I highly recommend this site!
