How to Troubleshoot & Replace Whirlpool AP6008773 / WP37001042 Dryer Drum Support Roller

It was a big job because the plastic fan shaft was stripped and it just spun around the metal motor shaft nut. I finally had to tear off in several pieces the plastic surrounding the shaft locking nut so I could grip the metal shaft with vise grips. Then it was easily removed. Once inside the dryer I replaced the 2 rollers, the idler pulley, and the belt and cleaned all the lint collected inside. My dryer is an Amana model ALE643RBW. One big problem in re-assembly was the top cover does not attach and release like the video shows. I found that all 3 sections of the front cover have to be released and dropped downward so that the top cover can be unscrewed. Start at the bottom section and then work upwards. Re-assembly starts by attaching the top section first and work downwards. The front/top section with the clips attached just slides slightly upward to join the top flat cover. The video just shows using a putty knife to release the locking clips and the top then lifts up. That does not work with this model dryer. Thanks for the parts which shipped promptly and the video help for other parts. My wife is now very happy with the quiet sound of her new dryer. The parts cost $124, (not counting my hours of labor), but a new dryer now costs about $600+, 

New element and rollers. I put on a new belt while I was at it. 

Replacement of part. Also replaced drum rollers and glides while apart. The Appliance Parts Pros video was very helpful. 

It was easy just watch the video how to replace the drum rollers and belt. Also a had to clean all the lint build up, the unit is 16 year old. 

Replaced drum rollers, glides and brackets, and belt. Right parts quick! 

Replaced motor. Watched several online videos on how to replace the motor. 

I replaced the heating element, the high limit fuse, the hi-limit thermostat, and 2 drum support rollers. 

Initially thought belt broke. After watching several of your how-to videos I removed the top and front panels only to find the belt intact. Once I removed the drum I discovered the belt tension idler pulley was at fault. I decided to replace the belt, drum rollers and belt tension assembly while I had it disassembled. Thanks to the informative videos you have posted on your website, my repair was easier than expected and took less time than I had imagined. Once again my 17 yr old Maytag is humming along. Thank you. 

The dryer was about 18 years old, and all the parts were "just plumb worn out." All the parts I ordered were genuine factory parts identical to parts in the dryer. Since I have been inside this dryer before, this repair only took about an hour. Good as new for a few Benjamins, a lot less than $1200 for a new dryer. 

New belt and rollers.
