How to Troubleshoot & Replace Whirlpool AP4008534 / 12001541 Dryer Drum Support Roller

After googling the issue, it sounded like the drum rollers were probably bad. Just in case, I ordered the roller axles too, as well as the drum belt and pulley bearing to replace while I was in there. The step by step videos that Appliancepartspros.com has make it almost impossible to screw up. I'm glad I ordered the roller axles, because one of them was worn to the point that metal dust was all over the bottom corner of the dryer. 

After reviewing your website for possible causes, and disassemble procedures, I disassembled the dryer unit. I found a lot of dirt but, also found a bad guide wheel that support the drum, the bearing in on the motor unit were leaking oil, and the blower wheel D shaft was worn out of shape causing the wheel to hit the housing. Also the original belt had air checking cracks which made sense to replace it. I decided to replace the thermostat per your website recommendation for solving over- heating. The felt seal on the front of the drum was damaged so I included a replacement in my order and installed a new seal. After receiving all of the necessary parts I performed the reassembly of the unit. After installing all of the parts I did a trial run and the belt jumped off the motor axle. After some fun reinstalling the belt properly I test ran the unit. Whoa it sounds like new. Oh but then a slight rattle noise started, I suspect because I did not replace the new drum roller axle that I purchased for the new drum roller. The noise seems to have decreased after multiple cycles, but I plan on disassembling the unit and installing the part. Over all the dryer is working like new, including the over heating issue seems to be solved too. Thank you for the great source of parts and installation videos. In the past I have also repaired my neptune washing machine multiple times using parts from AppliancePartsPro.com 

Replaced 2 drum rollers , door switch that was broken , new motor and belt. New motor hook up different than original requiring crimping on new terminals to several wires but able to follow documentation explaining procedure ! New Maytag gas dryer approx. 700.00. New parts with shipping 163.00 to repair this one ! 

I ordered the seal from Appliance Parts Pros. I also ordered the dryer drum belt and drum support rollers to do a basic overhaul on my dryer at the same time. I followed the videos online. The videos were generally right on. The only things I wished they pointed out was the difficulty in keeping the felt seal on the outside of the drum as you put the drum back into place. Since I replaced the front and back seals, this was double difficult. However, I got my wife to help and wound up getting the job done. This is a great website and I am a customer for life after this project as well as my first project last year in fixing my washer which first introduced me to this site. 

Ordered and replace all moveable parts to stop squeaking. Dryer performing like new!!! 

It all started looking for a lint filter for the dryer. The filter was ripped across the top and no longer useful for its intended function. I Googled "MDE6000AZW Lint Filter" and one of the first few hits was Appliance Parts Pros. I clicked through and saw that there were other parts available for my machine. That got me thinking maybe the squeaky bits and pieces are replaceable too. I started to watch Matt's videos on replacing the guts of my dryer and figured $500+ CDN for a new dryer or $145 CDN for all new guts. I'm not cheap or frugal, but this thing works like a dream. A new one is sure to breakdown well inside 14 years onward. So, I ordered two drum rollers, two roller axles, drum bearings, a new belt and of course, a lint filter. I figured from Matt's videos that it was likely one of the roller wheels, but since I was going to be opening it up, I might as well replace all the moving parts anyway. Shipping to Niagara Falls, NY was super fast. Everything was a piece of cake to remove and replace. It took about 2 hours with the bride's help, but we cleaned every bit and piece we took off and gave the inside a good going-over too. I could have done it alone, but it was nice to have a spare hand just to hold things as required. Thanks Appliance Parts Pros. All the best! Jay Turner @JayTurner901 

Watched the video for the repair.found the tools.had no trouble to complete what had to be done.thanks for video. 

Replaced drum support rollers and bearing wear pads. 

Using APPs videos and common sense. 

Replaced (2) drum support rollers, (2) dryer drum roller axles, drum belt, and belt tension pulley. I think only the (2) drum support rollers were the troublemakers. One of the drum support rollers barely would spin without a lot of force. While I had the dryer apart, it made sense to just replace all the potential causes. BTW...I did encounter a UPS carrier issue, unrelated to this store but the customer service agent at AppliancePartsPros.com took care of the situation and had new parts delivered in no time at all. ...Thank you!
