Product review (5 stars): Also Works On 20yr Old Whirlpool Dryers
This kit (4392065) is listed on the Whirlpool website as compatible will 2007 and newer dryers. My Whirlpool LGR4634EQ0 Dryer is almost 20yrs old, bought it new in '97. I did some research and found this kit contained the following parts, Belt = 341241, Wheels = 349241T, Idler Pulley = 691366. The wheels and idler pulley were the same as my 20yr old LGR4634EQ0, but the belt was not the same P/N (old belt = 3394651, 92-1/4 inches). Researching further on other parts repair sites I found the belt in this kit, 341241, was compatible with several other belts, including my old belt (3394651). The new belt is maybe a 1/2" shorter but fits just fine. Dryer is running great now after installing this repair kit, 20 bucks and done!

So if you've got an older dryer, pre-2007, and this kit doesn't show as compatible here on Amazon, don't be afraid to do a little research. I had even asked the seller if this kit would work for my model and was told no. My guess is any pre-2007 dryer will show as incompatible since Whirlpool lists this kit for 2007 and newer. But if you dig a little deeper, cross-checking with other repair sites, you just might be pleasantly surprised to see this kit is compatible with older models too.

P.S. There were a few other listings here on Amazon for this kit (4392065) that were a couple bucks cheaper, but some of the reviews had called into question the quality of the Idler Pulley. I can confirm that the Idler Pulley in the kit from this seller, Free_Shipping_LLC, is identical to my old pulley -- made from heavy duty metal.
