Ok, I'll begin by stating I cannot say 100 % that I have the correct model number. The tag bearing that info has worn off...I have cross referenced enough of known part numbers to guess that it is a medc400vw. The drum doesn't turn. When I got to where I should've had a broken belt in my hands, I didn't. The belt was still intact. However, the idler pulley was laying on the bottom plate of the dryer. It seems to be in working order, which brings me to my problem. I cannot for the life of me figure out how it goes back together, or if I should even try. There's a reason it's not engaged with the belt...my guess is a stretched belt. I need some guidance, my wife wants to know if this is the beginning of the end and we should buy another dryer or if it's worth the effort to repair.

The belts used on almost all dryers usally dont stretch but they wear out due to grooves wearing or cracks . There are generally 2 widths in use with the older dryers using a slightly wider belt . Newer dryers use a narrower belt and the length varies but usually there is about an inch difference in length. The skinny belts dont last as long as the wider ones.
