Product review (5 stars): Affordable Part + Online Tutorial = Fixed Dryer
Thanks to this part and an amazingly helpful video on YouTube by canyonman1963, we were able to repair our dryer for a fraction of the cost it would have taken to replace it or hire a repairman.  Don't let repairing your own dryer intimidate you.  They're actually fairly simple to take apart, fix, and put back together.  It's been about a month or so since we fixed it using this belt and it's working as good as ever.
