DG408 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.

Unplug Dryer. Remove two screws from front panel of dryer on lower left and right. Dryer front will swing out and up to release the hinges at the top of front panel. Set panel aside to the left and remove wires from switch at inner top left of panel (if necessary). There are 3 thermostats in this dryer. Two are set together at lower left and one is on lower right and sits back a little. This Cycling Thermostat is one of the two (on the lower left) and in my dryer, was the one on the right of these two. Check to make sure the numbers (and wire colors) on the replacement match with the thermostat being replaced, because it could be different from mine (Maytag couldn't tell me the difference). Remove the 3 wires from the thermostat with needle nose pliers and then use a 1/4" deep socket to unscrew the thermostat. Replace in reverse order.

first i removed the screws holding back cover. Then I remeved nut from tumbler roller shaft. Then I slid shaft from roller .I removed roller then replaced with new one. Installed new shaft then replaced back cover. recieved parts from parts direct very promptly & they were the right parts the first time thanks very much

Just unscrew the front of the dryer the Igniter kit is on the right side of dryer unscrew one bolt then replace with new Igniter kit very easy fix make sure to unplug dryer first that way you don't get a shock by touching exposed wires before putting front panel back on clean out any lint that may be in or around bottom of dryer.

Door switch was very easy to replace as it simply snaps in for the outside and you just clip on the two control wires that already have clips on them.

All you need for a Maytag is a snub nose Philips screw driver. The screws on the front panel are at the bottom angled down, so a regular length Phillip's won't work. Just unscrew the 2 screws, then lift the panel up and out. Careful not to pull out too far, there are 2 wires attached to the switch. The replacement switch is NOT an exact copy of the old one. My Maytag is over 30 years old and it only had 2 prongs on the switch. The new one has 3. Don't let that throw you. It is the same size. Just attach, 1 wire to the bronze connector & the other to the silver. Push the switch into the door opening, re-attach the door. Total time 20 minutes. Saved well over $100 in a service call. Anyone with an IQ above freezing can do it.

Replaced the flame sensor and the igniter. Probably didn’t need the igniter but put in anyway. Saved old igniter for a later time just in case it burns out.

1. Popped out old latch from dryer with a screw driver and pressed in new latch with fingers. Did not need to replace the part that is in the door. Very simple repair.
2. Lint filter was worn out and needed replacing.

Took the front off , removed front drum support, drilled out existing rivets, & replaced slides,riveted them in place,and re-assembled.

The directions provided to modify the gas valve were very clear. Getting to the gas valve I was on my own. Taking the top and the face off the dryer, once I figured out that there was no reaching the gas valve from any of the access ports on the back, was the only way to access to the gas valve. If you have worked on any other dryers, this modification was definitely doable.

I removed the cover from the control panel, took out the schematic, removed the rear cover by the motor, followed the schematic, powered the heater by taking the blue hot leg wire off the right side of the switch and touching it to the black lead for the heater on the left side, and I could hear the heater power on. Since bypassing the motor start switch powered the heater, I ordered the part. When it came, I installed it in about 5 minutes and the dryer worked perfectly.

Undid two screws in lower front of dryer and popped off front. Removed screws holding lint screen duct and brackets supporting tumbler and removed duct and tumbler quite easily. Pulled, cleaned and oiled rear rollers, replaced front glides, and thoroughly cleaned exhaust duct of lint. Put new belt into position on the roller before sliding tumbler back in, then pulled belt over tumbler as it went in. Be careful to follow belt path directions correctly.
Key to this repair was obtaining the parts so easily from Parts Select.com. Ordered at 2pm and had them 2pm the following day. Unbelievable! These machines are relatively simple to keep running when the parts are available so easily. Thanks for great service.

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!

I didn't think it would fit as it looked bigger then the old one, I called the service department and they were very helpful. They made note of the fact that I had called with questions in case I had to call again, but it worked, and no one laughed at me. It was very nice of them. Thank you for all the help
