I fixed it myself. I could not find a video for my Sears Kenmore model so disassemble was on my own. however the videos did show me how to thread the belt. also this was an opportunity to clean out the duct work of any lint build up. I would like to add the dryer is 15 years old with moderate to heavy use, and this is the first servicing. with new belt it runs like new. ran 9 loads through first day.
