MDE3500AZW Maytag Dryer - Instructions

This should have been a simple repair, but turned out to be time consuming and moderately difficult. I hope these instructions will help anyone who encounters the problems described here.

After a period of the dryer not being used, the idler pulley wheel froze on the shaft of the idler pulley arm, so I needed to replace both parts. After mounting the new wheel and two washers on the new arm and securing with a retaining ring, I went to install this assembly by going in through the small access panel at the rear of the dryer. I slid the belt off the old idler pulley wheel and unhooked the spring from the idler pulley arm; the arm was mounted on a sleeve fastened to the motor bracket by one screw. All that should have been necessary was to back out that screw and replace the old idler pulley assembly with the new one.

That is where the trouble started. Backing out the screw with a socket driver, I found it would go a few turns, then start to bind. I tried turning it in and out to get the threads to engage, but it kept binding. Eventually I gave the screw a hard turn, and then it would turn freely but not move in or out.

Looking on the internet for advice, I found a video that asserts for another model Maytag dryer using the same type of mounting for the idler arm, that there is a design flaw. You can find the video by searching for “Maytag dryer idler pulley defect”. According to the video, the sheet metal screw used to mount the idler pulley arm can gradually loosen due to the pressure and vibration, and begins to “waggle” which eventually damages the threads. I believe this is what happened to my dryer. The video suggests replacing the sheet metal screw with a machine screw and nut for a more durable union.

So now I understood how the screw could be stripped just sitting in the dryer, but that didn’t help me get the screw out. Working through the rear access panel, I tried pulling on the screw head with several types of pliers, pushing the point from behind with a piece of wood while turning the head with a socket driver; eventually I was able to use a pry bar under the screw head and sleeve to apply pressure while turning the head, and with that method the screw backed out. With the screw removed, it could be seen that the threads in the middle part of the thread length were almost completely worn away.

The screw sleeve got somewhat deformed in this process so I ordered a new one, along with an exact replacement sheet metal screw, hoping the threads in the hole were still intact. With the old idler pulley arm now removed, I could transfer the old idler bracket spacer to the new idler pulley arm. When the ordered parts arrived and I tried to mount the idler pulley arm, the new screw would go in only a couple of turns before binding. Rather than risk winding up in the same situation by forcing the screw, I decided to use a machine screw and nut instead.

The original sheet metal screw was a #10. A machine screw the same size would not fit through the hole, and I could not fit my drill into the dryer cabinet in a position to enlarge the hole, so I used a #8 machine screw with a nut and lock washer. First I put some grease on the contact areas of the screw sleeve and idler bracket spacer, then inserted the machine screw through the hole and put the lock washer and nut on the other side of the mounting. The space around the nut is very limited, and most of my tools were too large to hold the nut while the screw was tightened. It was too small for a socket or adjustable wrench, and the clearance from the exhaust duct was too small for the handles of most tools. Eventually, I found a needle nose pliers with short handles that did the job. A thin open end wrench might also work. Then I reconnected the spring and belt to the idler pulley assembly, and closed the access panel. So far the dryer works, but if the #8 screw turns out to be not strong enough, I could get an extension for my drill and enlarge the hole to fit a #10 machine screw and nut.

Looking back on the job, the most difficult part of this repair was removing the damaged screw. This and several other steps might have been a lot easier if I had removed the motor bracket (where the idler pulley arm is mounted) from the dryer and worked outside the cabinet. Part Select has an excellent video “Replacing the Drive Motor” that shows how to do this. It would be a lot of disassembly work, but for someone with good assembly skills could be easier in the long run.

Hopefully most folks out there who replace the idler pulley arm on a dryer will find an easier situation than I did. But for any who have to deal with a stripped mounting screw, I hope this summary will help you resolve it.

I looked at this website and found the symptoms, noisy, and no heat or not enough heat. I ordered the recommended parts. They were the drum support roller kit, idler pulley wheel and bearing, high limit thermostat, and lastly the front glide kit. I had anticipated having to use all of these parts. Upon following the instructions in the videos (couldn't ask for better instructions) I disassembled the dryer to see how bad everything was before replacing the parts. The left drum support roller spun easily, but had a little roughness and slight noise, the right one spun easily but not like I thought a new one would have spun, the idler pulley was stiff and very noisy. The thermostats all seemed to be in good shape (had continuity). I cleaned the bearings and shafts of all of the rollers with alcohol, paper towels and cotton swabs. The bearings and shafts all looked like new, so I lubed them with a slight amount of high temperature grease and reassembled the rollers. They moved smoothly and quietly. The fan was quite full of lint, even cleaning the filter after every load does not stop all of the lint. It has been in use probably over 10 years. After everything was back together, it runs like a well oiled sewing machine and has been drying well. I did return the parts unopened. This would not have been so successful without the videos. Thanks to all of you.

Replaced damaged parts and recommended parts normally causing the problem. Dryer is working again like new. I expended $112 rather than $600 for a new equipment. Good deal!

I had replaced belt, but the noise continued. Ordered new rollers and washer. Removed the front panel by tipping the dryer back against the wall and removing two screws at the bottom of the panel. Tipping the dryer makes it easy to remove the front panel. Removed the front drum support by removing four (4) screws. I was then able to just move the drum enough to have access to the rollers. Didn't even have to remove the belt. Replaced the rollers. Needed special pliers to remove and replace the retaining rings. Put the drum back into position and mounted the front drum support. Tightened four screws and then put the front panel back on. Plugged it in and tested it. Problem solved. Took about 35 minutes. Thanks

To replace the light bulb, I removed the screw and the cover, unscrewed the old bulb, replaced with the new bulb and replaced the cover, securing it with the small screw. It worked appropriately with normal use for a few days and then I noticed the light was not coming on when I opened the door.

I removed the cover and pulled out the bulb to find that the filaments inside are dangling and burned through. I need them replaced, please.

Just took the old one out and put the new one in! Fit perfectly! Very happy with your service and part came super quick!

I was able to quickly make this repair with the help of some instructions that I found on this site on how to remove the front panel of my dryer. 4 screws on the front around the door (and removal of the door) and then it was simply a matter of rolling the top portion out to pop it out of some clips and then the front panel opened toward me and I was able to lift it off of the metal fingers that secure it on the bottom. Removing the old baffle was a matter of removing two screws with a nutdriver and installation of the new baffle was a breeze. All in all I was done start to finish in under 10 minutes.

Piece of cake. Use the available manual to ascertain dismantling procedure. Only thing that might be tough for average DIY'er is the internal snap rings. Snap ring pliers are mandatory for quick easy repair.
Total time was probably about 15 minutes and this was the first time I had taken it apart. Quiet as a mouse now!
Very helpful site.

Took off front. Removed door. Removed drum support. Removed drum and belt. Made sure motor was correct size and fit. Removed blower wheel. Disconnected wire plug from motor and slid motor out of blower wheel. Replaced everything in reverse order. Figuring out belt tensioning position was a trip, but finally got it. Vacuumed out all the lint. Amazingly it worked!

Replaced both rollers,shafts, bearings and snap rings.

I looked up my problem online and everything I saw said to change the roller wheels that hold the barrel of the dryer. After doing that (twice, once on each side) I was still having a horrible squeaking sound so bad that we were waiting to do laundry until we were leaving for a while. Finally I determined that the problem was actually the idler wheel. All I had to do was remove the bolt holding the idler arm on (it's the arm that has a spring connected to it that moves to allow the belt on or off) and put the new arm with the new wheel on. The dryer is now whisper quiet and works perfectly.

The dryer started making a screeching/squealing noise…when it became unbearable, I decided to research the problem and found this website - it was tremendously helpful.

Based on what I found, I decided to order two drum rollers and two shafts – hoping that would solve the problem. My husband and I disassembled the dryer and replaced those parts. We also vacuumed the unit and wiped down the 10 years of gunk. Honestly I am surprised we have not had a fire given the amount of dust/lint inside the unit. I also took the opportunity to give the vent a good cleaning as well.

We put the unit back together, turned it on and listened to the quiet hum of our renewed dryer. Until about 15 minutes later and then the screeching/squealing started again. Kicking myself for not ordering the idler arm and shaft as well as the idler pulley wheel and bearing the first time – I went online and placed another order.

We took the unit apart a second time. We did inspect the pulley the previous time, but it appeared in good working order. Not seized like some of the other posts mentioned. Upon further inspection, it did seem to make a squealing noise when we wiggled it – duh!

The unit was put back together, quietly doing it’s job and we feel confident that we will get a few more years out of it. The videos were extremely helpful as were the posts from other do-it-yourselfers. We saved a lot of money with this fix.

Good luck!

BTW - The Lint Filter was not a problem - I just thought after 10 years, we could use a new one. I laughed when I saw the repair video on it!

Initially I thought let me call so and so but then I thought, "wait, let me google the model and make and I looked up what I thought might be the part. So for $15.00 I fixed my dryer. I was very proud of myself and my husband was happy I saved him money!

i removed the 2 screws holding the door hindges on. then i removed the 2 adjasent screws to remove the front door panel. i rotated the drum to aceses the screws holding the baffle and installed the baffle .

Per instructions I printed off online: took off door, then the front panel. Pulled out the old switch/button, connected the new switch/button, made sure the new button was working; put the panel back on then the door and DONE!
