Product review (5 stars): Great belt from the OEM at a great price.
Belt on my dryer broke and this one fit perfectly.  Belt came with directions, but I got better ones by looking on you tube.  Directions with belt say to do it all from the front of the dryer, but I found it much easier to remove an access panel on the back and loop it over the pulleys from there.  And since my dryer was broke, it was great I could get this in a few days using Amazon Prime.
