How to Troubleshoot & Replace Whirlpool AP5983729 / 661570V Dryer Drive Belt

Disassembled dryer (following video on website), impacted belt, pulleys and rollers. Found belt frayed and tension pulley didn't spin well. Replaced these and drum rollers because rollers were inexpensive and I already had it apart. Reassembled and works like new. While apart I took the time to vacuum the line that had gathered and also in vent/fan housing. 

Ordered belt which came in 2 days. Wife on iPad using your utube directions and husband wielding tools. Dryer up and running in 4 hours- this includes taking apart and reassembling. Thanks Applianceparts pro for part & instructions 

Replace it and also the belt???? 

First i watched helpful youtube videos by appliancepartspros and others. I learned of several probable causes and solutions, and dryer disassembly tips. I began disassembly, and discovered a broken dryer drum belt. It was a sears kenmore dryer, and the i was able to look up the belt by part number and dryer model number on the internet. I checked a few different suppliers, and found appliancepartspros.com to have the best price and most accurate cross referencing for the part i needed. I ordered the new belt online and it arrived very quickly in 2 days. I installed the belt, re-assembled the dryer, turned the dryer selector to an "on" position, and pressed the "start" button. It works! 

Replaced entire Idler Pulley assembly and also replaced belt while I was at it. 

I replaced the broken belt with a new one. The repair itself took about an hour. Cleaning out all the lint that accumulated in and around the dryer and installing a new vent hose (something to consider if your dryer is old enough to need a new belt) added another 30 minutes. 

I looked up the possibilities on Google, and watched the FYI video from appliance parts pros. I ordered the parts on Sunday and everything was delivered on Tuesday with standard shipping. I did The repair myself thanks to your video and my dryer is as good as new. Thanks for making this repair an easy fix!!!! 

Disassembled dryer, pulled out the tub, removed the triangle shaped fastener, pulled off pulley and back washer, put new washer, pulley and new retainer. Slide new belt over the tub, installed tub on to the back rollers, reach under the tub an put belt on pulley, then pulled tension pulley back against spring tension, slid belt over pully. I then turned tub by hand to make sure it turn. Reassembled remaining parts plugged it in, turned it on and problem solved, no more squealing!! Replacement parts worked great, perfect fit! Thanks Allan 

Ordered drum supported, belt and idler pulley. Received the next day, lightning fast,door to door. It took an hour to install. Cleaned all the vents before installation. Runs great. Bought in 2007. Whirlpool Duet works well. 

My Dryer had no heat but seamed to work perfectly otherwise. I pulled off the front panel and found a huge amount of partially burnt and what looked like super-heated lint everywhere. I vacuumed out all the lint and used a lint brush to loosen and clean the entire dryer insides. I used the helper videos and found the High heat fuse was burnt. I inspected all the seals and electrical parts. I ordered the needed part and installed them and the dryer works perfect. Thank you for all the help/info to do the job right.
