Chuck C Yakima , WA January 09, 2021 Appliance: Maytag Electric Dryer LDE7800ACL Maytag Dryer Lde7800acl: Noise from drum rollers and failing drum belt. How to replace Drum Support Roller. I installed new drum roller axles, new drum rollers, a new idler pulley wheel, and finally a new drum belt. I had checked out how to make the repairs on YouTube so took less than one hour to do everything. The drum roller axle on the right side was the only thing that took a bit to break loose. Even with that, it took less than an hour. The first problem with this dryer in 27 years old. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
