Ordered a new dryer roller assembly from APP. I received it the next day, and I watched the video that LITERALLY took me step by step! Video was to replace the belt, but the roller was one step before the belt, so I just skipped the belt part and replaced the roller assembly.
Initially, it seemed like a lot to disassemble but when you follow the steps, it was super easy and took me less than 30 minutes. I didn't just order the wheel, but the whole assembly, because I needed the bolt that comes with it.
