Santiago C Silver Spring , MD February 11, 2021 The drum doesn't rotate. It was very, well somehow easy. The dryer's idler arm was worn-out. Which makes the belt go out of the track. So I replaced it and at the same time, I changed some other related parts to make sure works longer. Thanks, everything fits very well. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
