Matthew L Elizabeth , CO October 04, 2020 Appliance: Kenmore Dryer 79681072310 Kenmore Dryer 79681072310: Drum support rollers bad, plus fix common parts. How to replace Dryer Idler Pulley Assembly. Watched the videos provided by Appliance Parts Pros which were very easy to follow. Pulled the dryer apart and got to work. Since I had to pretty much pull the whole dryer apart I replaced multiple parts that go out. Obviously more cost-effective to fix my dryer than to buy a new one. Thanks, Appliance Parts Pros.
