I'm definitely NOT a person who typically does DIY appliance repairs, but I decided to give it a shot this time. My dryer drum stopped spinning, so I assumed it was a broken belt. I pulled the dryer apart to discover that the idler pulley wheel had broken off the pulley assembly, so ordered a replacement and easily replaced it, making sure to follow all of the steps outlined in the very helpful video on the product page here at appliancepartspros.com. It was easier than I imagined, and not very hard at all. Saved me a ton of money!
