Product review (5 stars): Very cost-effective replacement and upgrade to original equipment with friction pad instead of idler roller
My Whirlpool dryer which was otherwise working fine would screech for a few minutes after a cold start. I researched and learned one of the components of this kit would most likely fix the problem. Following videos I found online disassembly of the dryer was actually quite easy (I am no stranger to appliance repairs). While I did not isolate the screech when I took it all apart I was happy to learn that the original idler arm (belt tensioner) was not a roller but instead was this semicircular friction surface. I replaced the other included rollers and the clips (I found the new design of the triangular clips to be annoying to work with). I replaced the belt and routed it correctly around the idler roller and reassembled the dryer. Since then there has been no screeching from cold start, so I am very happy with the results and the price I paid for the kit.
