Product review (5 stars): Received a Complete Kit, But Only Installed the Belt
My dryer drum abruptly stopped spinning while attempting to dry a load 5-7-17. I felt the heat, so I knew none of the parts involving thermostat, switch, ignitor, or coil were the problem. I also heard the motor spinning, so I chanced it on ordering the tensioner with a belt, minimally, before opening the dryer up.

Well, when the kit arrived (5-9-17),  I unplugged the dryer and removed the front cover with door assembly. I immediately saw the belt had snapped and in fact frayed leaving belt dust & burnt rubber sprayed about. So I went a step further and removed the drum to thoroughly clean it out using a vacuum followed by a damp rag. In some spots I used WD40 to clean. I use WD40 when cleaning various items in the automotive & repair industry, especially for stubborn spots. It's non-abrasive & not too harsh chemically.

After comparing the tensioners, I decided to reuse the old one due to the fact it was beefier & the replacement had a few differences. Also because this tensioner uses no bearings, only metal bushings on a metal shaft. Then I compared the drum rollers, but saw no noticeable wear nor was the rubber hard or dried out, so I decided to keep the old ones in place.  I reinstalled the drum, placed the belt and reinstalled the old tensioner. I spun the drum by hand to make sure all was aligned and moving freely, replaced the front cover assembly and gave it a try. So very thrilled, all is working as it should. This is seriously the cheapest component to have to replace & best case scenario all around. I'd definitely recommend these parts, but can only verify the quality of the belt. Again, tensioner, I wouldn't use.... and I posted photos of comparisons along the job I did.

The gas dryer I have is Whirlpool LG7681XSW3

I bought this from the seller "Cheddy" but fulfilled by Amazon.com, which I feel is important to list this info. I've come across sellers with variances in their items, including knockoffs, even if listed as same brand. I'll post an update with a durability review.

***UPDATE*** 8-16-17
it's now been about 3 months since I had to do the repair, and all is still well. I call this a win.  If the previous belt durability was any sign of how long this one will last, I should be fine for at least another 10 years.  I'm just so glad there are companies still making these parts!!
