I opened the dryer & discovered the broken pulley. I ordered a new pulley assembly, belt, & spring. My old belt was not damaged but I ordered a new one since I had the dryer opened for repair. The difficult part of the repair was reattaching the belt around the idler pulley & to the motor. You have to be able to attach the belt by feel only because you have very little space to see the belt & pully. I used the video provided on your parts lists to make sure I was attaching the belt properly. After the repair it was just a matter of figuring how to reassemble the dryer. The dryer works fine now.
