For about 2 days my dryer had a squealing noise then yesterday it stopped working. I took the dryer apart (front, back, and top) and cleaned all the lint/dust out. When I put it back together it started up and dried a load of clothes. It was louder than usual, but it worked. I tried to dry another load but it only worked when I opened the door and manually turned the tumbler. Now it's also stopping before the timer runs out. Please help.
