LDG21CS 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.

Disassembled per instructions. Additional time used to clean inside unit.. Its much easier to install belt on motor pulley and tension pulley ( Roller) from rear access panel. Also ensures proper belt alignment on all items.

I looked for dryer repair videos on my computer. I found several and they all showed me that what was most likely broken was the tumbler belt. I didn't even know dryers had a belt. My dryer still turned on,and still produced heat. It just wouldn't rotate. One of the videos even used the exact Maytag dryer in their video that I had. After watching it a few times, I knew I could make this repair. I am pretty good at fixing things if I can first see it done. I had never taken a dryer apart before though. I pulled the dryer away from the wall and unplugged it. I unscrewed the small access panel on the back of the dryer. This let me see the two belt pulleys back there. Then I went to the front and removed the two screws(my particular model) that held the front panel on and removed it. I then unscrewed the four screws holding on the front face plate in front of the tumbler. Next, I pulled the tumbler out, it is not screwed in. There was the broken belt. It took two days with regular shipping for the belt to come in. I put the tumbler back in, resting it on its two supports, placed the belt on, flat side down, and routed the belt through the pulleys in the back of the dryer exactly as it had been shown in the videos. I turned the tumbler clockwise two full rotations by hand to make sure the belt was seated correctly on the pulleys, and it was. I then screwed the face plate back on in front of the tumbler, put the front panel back on and screwed it in. I then reattached the back access panel. I plugged the dryer back in and turned it on. It worked. Though it may take a bit longer, this type of repair is about as easy as replacing a broken belt on a vacuum cleaner even for someone who has never done a dryer repair before. Watch a Repair Clinic video and if you enjoy fixing things, replacing a belt on a clothes dryer will be your next successful repair. It really is pretty easy.

Replaced both rollers,shafts, bearings and snap rings.

My Maytag gas dryer model MDG7600AWW is about 12 years old. Everything else works fine except it takes 4-5 drying cycles instead of 1 to completely dry my clothes properly. The flat igniter was simply cracked but not broken so it only worked some times. My gas dryer igniter and the 2 ignition coils work hand in hand so I replaced all 3 parts. The ignition coils provide a solid and consistent power supply to the igniter for proper burner tube function. Disconnect power cord from wall outlet. Shut off gas supply by turning the wall gas valve off. Remove 2 small philips screws to detach front panel door from dryer frame. Remove 2 additional philips screws on left front side panel inner door frame. Gently pull front dryer panel off beginning at top and put it aside. Igniter and the 2 ignition coils are plainly visible and easily accessible at bottom right corner of dryer. Igniter is attached to the burner tube and facing into the heater housing assembly. The 2 ignition coils are attached just above the gas valve on the rear of the burner tube. The ignition coils are simply attached to the rear of the heater tube with one bracket using 2 small philips screws. First, disconnect igniter plug wire harness. Next, I recommend using a small open end applicable size wrench (5/16 perhaps) to remove attaching igniter screw. A small 1/4 ratchet with applicable socket size may also be used. Handle the igniter only from the white ceramic part when installing. You don't have to completely remove the igniter screw from the burner tube. The igniter has a white ceramic horse shoe shape slot in which the attaching screw goes through for tightening to the burner tube. Just unscrew generously for removal and replacement of the igniter. Do NOT over tighten igniter screw as the white ceramic plate may break from over torqing. Reconnect igniter wire plug harness. The igniter part I used was PartSelect Number PS373025. Next, remove the ignition coil bracket by unscrewing the 2 small philips screws from rear of the heater tube frame. Remove only 1 ignition coil at a time by removing the wire plug harness and simply lifting upward. One coil will have 2 prongs while the other has 3 prongs so you can't go wrong when reconnecting the wire plug harnesses. I used the PartSelect 'M' Series New Style Coil Kit (2 coils included)which was PartSelect Number PS334310. Replace the front dryer panel back. Attach the front door to the panel and dryer frame using the 2 philips screws. Attach the 2 left side inner door front panel philips screws to dryer frame. Turn on the wall gas valve. Reconnect power cord to wall outlet.

Upon receipt of part, just loosened 1 fastener, slid igniter forward and out....unclipped wire connection and replaced... Could not have been easier. Be careful not to overtighten fastener when replacing. Description and pictures made for very easy selection.

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 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

I removed the front panel (two screws at bottom, then lifted bottom toward me until the top holders slid out). Then I unscrewed the front assembly that holds the dryer drum (four screws), first propping the drum from below so it would stay in place. I removed the blower housing (seven screws) and could see that the blower wheel was loose on the spindle. The 'D' shaped fitting had rounded out. A pair of snap ring pliers made removing the retaining ring and the wheel clamp a cinch and saved a good deal of teeth gnashing. I slid on the new blower wheel and then did everything in reverse. One caution: be sure the drum is pushed firmly up and back when reattaching the front assembly. (It can be done successfully with two hands). I had to re-do this part of the reassembly because the bottom of the drum was rubbing against the blower assembly. Once that was corrected, the dryer ran noiselessly. Thank goodness for PartSelect's diagrams. They're invaluable.

Removed front panel and tumbler, replaced roller axle,
wheel, and front glides. Anybody can do this.

Turn off circuit breaker or unplug. Remove two screws 4 inches from bottom front panel of cabinet with stubby phillips head. Pull panel towards you about 30 degrees; then wiggle it down, to free two steel spring clips holding it to cabinet. Pull off red and yellow wire from door switch. Now set front panel aside. Blower assembly is facing you at lower left. Open the housing by removing six small screws from cover and one attached to dryer base. Remove spring clip from end of shaft. (A circlip pliers helps to prevent it from springing off somewhere.). Squeeze spring retainer surrounding blower wheel shaft with regular pliers, and wiggle the blower off. Replace in reverse order. Be sure insulation around blower wheel housing seats properly into front panel. This keeps the hot air flowing up past the lint trap.
Easy job, about half hour. Mine took longer, because I had removed the belt and drum, thinking the noise came from bad drum support rollers. It was just the plastic blower wheel shaft seat, which had worn itself round. Cost $20 (including shipping) and my 29-year old Maytag is as good as new--at least for now.

I had my oldest son who was home from college help me. We removed the front face of the dryer and put the unit on it's back. We removed the door switch and the blower unit. I didn't get a good look at how the belt was routed when we removed the drum but was able to figure it out when we put it back together. Not only was the belt frayed and dry rotted, the blower squirrel cage was free-wheeling on the shaft. I found a tab of metal I was able to insert in the flat of the shaft between the cage bushing and the shaft and I put the squeeze ring and snap ring back in place. We also discovered the source of much of the rattling noise we had grown accustomed to was actually change pieces trapped under the drum ribs. We removed them and put the ribs back in place and we installed the new belt and figured out how the belt routed around the shaft and tensioning pulley. We cleaned all the trapped lint out of the dryer and reassembled the unit. It now works like new. Thanks!

My wife had to help me due to a recent back surgery that I had.

1. Disconnet power. Then if you have room, slide dryer away from wall far enough to tilt it slightly back. We had to do this to remove the two lower front panle philips head scres due to my screwdriver length. If you have a stubby, then you don't need to do this. Remove by pulling out on bottom until the two clips at top disengage from dryer top panel.
2. We removed the four 1/4" head sheet metal screws that hold the front tub support panel (with lint screen). Be carefull of wiring. One moisture sensor wire has to be removed from front cover on lower right side near bottom of tub opening. The remaing wires on left side are long enough to leave them attached and "swing" front panel to your left and in my case, lay it back uprite against the washer front.
3. We slid the tub forward enough to lay old belt down so I could see how it was routed around drive. I wanted to verify paperwork that came with new belt. We then set entire tub out of dryer. You might want to take it to another room if you laundry room is cramped.
4. We removed the nut from back of each support roller shaft, I believe it was 3/8 hex. Then reveresed this procedure to install the new roller and shaft. It was easier to assembly rollers before installing as a unit.
5. I removed the old belt and confirmed its length to new belt. I then installed the new belt over drive sheave and tensioner.
6. We then installed the tub and worked belt around it while keeping it on the drive sheave and tensioner pulley. Had to kind of stick my head into tub to start belt unto it.
7. We checked tub front and rear felt seals and I would recomment\d changing these if your dryer is older than 10 years, we did not have then so kept old ones.
8. We replaced the front tub support and installed the four sheet metal screws.
9. We replaced the front cover and installed the two lower philips head screws.
10. Re-connected power and tested operation.
