Product review (5 stars): worked well
My dryer's belt snapped, so I replaced it with the new one, and the new one snapped just few days later, so I knew the problem was not with the belt itself. I could see that the drum would start spinning as it supposed to, but then slows down until it stops, while motor is working and melting the belt. ,I researched online and found this kit. It came with new belt, idler assembly and rollers (with the plastic triangle washers for installing, and little metal stopper) The instructions were very clear. It was easy to install, except the triangle washers were real pain to remove/put back. Managed to do it by wrapping the shaft with some paper, and sliding the washers over the paper to their place.
Now the dryer works well again, we will see how long it lasts.
