I looked up the model of my dryer in the information plate on the appliance. I did a web search and found Appliancepartspros.com which had the belt that turns the drum in stock. They had a video I watched which showed in detail the exact procedure to take dryer apart. I took dryer apart which was very simple, belt was broken, also I checked the idler pully shown in the video and it wouldn't spin freely. I ordered the belt and pully. I needed the part quick but the website stated that even without expedited shipping the average time to receive an order was 1.7 days. I was skeptical but I just used the standard shipping. I was surprised that in the afternoon of the 2nd day my order arrived! Part were exact replacement. I watched the video on the install. Took me less than 30 minutes and all works great! The parts were not costly and the job was simple. I will use this site again anytime I have a problem with an appliance! Thanks a bunch
