My father and I reviewed the video that was supplied on the page of the drive motor. The demo was great preparation for when it came time to work on our dryer. The best part was the "what if(s)" were answered. The blower wheel cracked and we bought it from this site as with the drive motor. It was nice to be prepared. Once we got the wheel in which was quick in delivery, we fixed the dryer within the hour we started. Great sight with great prices, shipping speed, and videos as well. Can't recommend enough.
