How to replace Dryer Drum Support Roller. After reading through the diagnostic help and watching all the related repair videos I decided to replace everything in the rear drum support system along with the belt and idler pulley. I figured that the most time consuming part of the repair was disassembly and reassembly. Might as well do it all at once, Replaced drum support rollers, axles, idler pulley and the belt. Each of those parts took about 5 or 10 minutes. Entire job took 1:45. And that includes time to vacuum out 12 years of lint, and stopping to review the videos as needed. As someone else mentioned the drum support roller and axle nearest the heating element were far more worn than the other side. Actually found ground up rubber from roller wear. And the belt was extremely worn in spots- I suspect the drum was actually hanging up from time to time. Easy repair for the most part, the disassembly and reassembly were actually the hardest part, I have 2 tips- get a pair of snap ring pliers. Saves a lot of vocabulary words! And a small magnetic LED work light to be able to see inside the machine was very useful. Dryer now is running smoothly and quietly. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
