DG412 Maytag Dryer - Instructions

I removed the two screws holding the access panel, and removed the access panel. Then removed the lower air duct. I then checked the burner, The solenoid was not opeing the valve for the gas. I order the coils, in two day I had the coils and installed them. The dryer is working great.

My 11 year old grandson and I did the repair together. He had a blast and I did too. First we removed a bunch of screws that got us no closer to getting the machine apart than when we started. Then I remembered from the last time I had the machine apart that there are two screws just below the door, angled as not to be visable unless you know where to look. Once we removed those the from came off. We removed the wires for the door light and heat sensor, remembering the order of the wires for later reinstallation. Then we undid the bolts holding down the top. Once the top was removed we took off the belt and removed the drum. We used the retainer pliers to remove the retainer ring from the first roller. We removed the roller and also the shaft as this roller was the noise maker and the shaft was not in reusable condition. We installed a new shaft, roller washer, roller, another roller washer and then the retainer ring. We repeated the same process on the other roller, although we did not replace the shaft as it was in good condition. It turned out I did not need to order the shaft washers as the rollers came with washers. Oh well, its not a good job unless you have parts left over when you are done. Once we replaced the rollers we commenced reinstallation. But first we had to google for diagram of the proper belt installation, which we found and that got the drum and belt installed properly. Thankd god for the internet. Once we had the drum installed we put the machine back together in the opposite order we took it apart. An operational test showed we did the job right, no more squeaking. The only injury was my grandson cut his thumb right after I gave him the speech about watching where your hand is going to end up when that bolt breaks free. It broke loose and into the metal bracket went his thumb. Oh well it was a good lesson and it was not a bad cut. All in all a good repair.

After replaceing several parts including the thermostats the last part I replaced the coils were the defective part. I originally metered out the themostats and they appeared to be okay but since this was my first time I thought I might have been mistaken. It turns out the last part I thought it could be was the part that was defective. I will say that it is very simple to replace any of the parts involved. The hardest part was trying to open the dryer itself. But after having to do it 3 times, I'm now a pro. I also replaced the drum belt and since I had it open I also replaced the belf idler with a newer modified idler rolller.

Putting the belt back on is easy, but it helps to view the video or a picture to understand how the belt goes around it.

First I unplugged the machine; an essential to avoiding getting shocked during this repair. This is a must and should not be overlooked it could cost you your life.

Removed two screws from lower area of front panel, pulled bottom of front panel toward yourself so as to swing out and up, continue to swing panel up to your self until it comes free from top clips.

Once free set gently on floor and remove door switch wires, noting which wire goes to which contact is not essential but could be more convenient when putting it all back together.

Remove door switch wire from clasp at top inside from panel, set front panel aside in safe place.

Now look under the two top front corners on the inside and you will see a screw in each corner; these screws must be removed in order to raise top panel.

This is kind of tedious because sometimes these screws are long and difficult to turn and space is limited and tight in getting rachet or nut driver on the head of these screws.

Be patient , because they will come out with a little work. To make this process a little easier you might do the following step first but you cannot do this little trick when putting it back together.

Once these screws are out raise top panel and lean back against wall; be careful because the two enamel surfaces are slick and if leaned too far back the top will want to slide out at the bottom from being on a lean.

Remove four screws from tumbler front, lift slightly so as to come off side clips then pull straight out. Remove door wire from clasp and drop wire gently back inside so as to let it fall to the bottom of the machine and away from the tumbler, which is to be removed next.

Once this is done the tumbler will go down in the front due to pressure from belt. The belt could have been removed from pulley right from the start to relieve this tension but I just do it this way.

Once tumbler sags or leans down in the front gently work the belt off of the back of the tumbler; there will still be a little pressure on the belt and gentle force may be required in sliding it toward the back and then off; once belt is off gently lift tumbler up and out and put in a safe place.

Once this is done you will be able to easily see everything in the bottom of the dryer; motor, gas valves, thermal switches, vent pipe and pulley, pulley bracket and belt which by this time has fallen to the bottom of dryer; gently remove belt from pulley and set aside in safe place.

Make sure it is out of reach of children or it will be played with or used as a hangmans noose; it is long an flexible and children just seem to love playing with it.

At this point you can either continue to work from the front of the machine or the back; I f you choose to work from the back then lower the top panel so as to allow it to just sit back down on the sides of the machine, pull the machine away from the wall and work from the back; because I am experienced at this I continue to work from the front.

If you choose to work from the back then while standing in the back of the machine look to lower right corner and you will see an access panel with four screws in it; remove these screws and the panel will come free giving you a clear view of the belt pulley.

From either back or front view you will see a spring attached to pulley bracket which can easily be removed when pulley bracket is in relaxed position; remove this spring and put in a safe place if you have plans of reusing it. I installed a new spring on this repair.

Once this spring has been removed then look directly beneath bracket at what is easily seen to be its pivot point and you will see a mounting screw. Remove this screw with a nut driver and the bracket will then come completely free; slide through access hole and come out with it.

Once it is out the white spacer is easily seen on bracket; look at the bracket side of the spacer and you will see a mounting screw; remove this screw and spacer will come off.

When installing new space

Switch can be removed from outside of dryer and your video described the repair as having to work from inside dryer. But since wires were still attached to old switch, it could be popped out and wires switched. Since there were three wires on new switch to allow it to turn on and off a circuit, it was useful to check the resistance of the switch compressed or released to be certain I was attaching the two wires to the right two poles of the new switch. But that all required only a couple of minutes. Thank you.

Unscrewed 4 screws,pulled off front of machine.Unscrewed 2 screws holding coils on,unplugged coils,installed new coils,plugged in coils,reinstalled 2 screws for hold down brace.Reinstalled front cover,plugged dryer into outlet(remember to unplugged dryer before working on it).started up,instant heat,works great.thanks Partselect for helping me out!!!

We used previous installation instructions, which were quite good – we embellished the directions where we ran into some things that weren’t mentioned.

1. Remove the back access plate to release the belt from the pulley.
2. Remove the two screws at the bottom front of the dryer, rotate the front to release it at the top. Remove the wires from the door status switch.
3. Remove the 4 nuts holding the drum support frame and pull straight out.
4. Putting one hand inside the drum and supporting it, gently pull the drum toward you until it clears the rollers. Reach in along both sides of the outside top of the drum and slide the belt off the back of the drum. With a hand inside supporting the weight of the drum tip the drum slightly forward and out the front. Set it out of the way.
5. Remove the two bolts holding the thermostat cover (silver odd shaped metal plate at the front of the dryer).
6. Remove the dryer blower cover plate by removing the 6 bolts holding it to the blower housing with a short ¼” nut driver. Remember to remove the bolt holding the plate to the bottom of the dryer.
7. Release the door status wire from the clips on the left side of the dryer and set the blower housing plate to the right, out of your way without removing the wires.
8. Remove the blower wheel by removing the snap-ring at the front of the shaft and then removing the collar- compression clip.
9. Pull out the blower wheel (this was a bear as it was very tight on the shaft – the shaft-collar of the blower wheel has grooves in it. We used very small screw drivers to carefully pry the segment of the collar between the grooves away from the shaft and used a penetrating oil and with a very slight rocking force muscled the blower wheel off then removed the rear snap-ring from the motor shaft.
10. Release the 5 wires attached to the motor.
11. Remove the ground wire on the back of the motor by backing the screw out.
12. Release the front and back motor clips (Use a large straight-blade screw-driver to press down and out on the end of the clips.
13. Lift out the motor.
14. Remove the rear pulley from the motor using an Allen wrench and transfer it to the new motor (We used heavy duty thread locked on the Allen set screw. – When we removed the pulley it was necessary to heat the Allen set-screw area with a propane torch to soften the thread-locker cement. IF YOU NEED TO DO THIS MAKE SURE YOU LEAVE PLENTY OF TIME FOR THE PULLEY TO COOL BEFORE YOU HANDLE IT!
15. Set the new motor in the support frame, ensuring the lips of the vibration isolation rings are pointed down to slip over the frame and are not facing up towards the clips ( makes clip installation much easier).
16. Hook up the wires, following the color coding on the motor controller you are attaching to.
17. Hook up the ground wire on the back of the motor.
18. Reinstall the rear snap-ring, blower wheel (went on a lot easier than it came off), front snap-ring, collar-compression clip, blower housing front cover (Including the bolt to the dryer bottom) ,
19. Re-route the door switch wire up the left side and secure with clips.
20. Reinstall the thermostat cover,
21. Reinstall the drum and belt (use scotch tape to temporarily secure belt) , the drum front support frame (ensure the felt seals for the drum and the blower cover are properly aligned and seated correctly),
22. Reinstall the belt through the back access panel over the pulley and idler wheel (make sure the belt smooth side is against the drum, the grooved side against the pulley and the belt is inside the belt guide on the idler wheel and remove the scotch tape from the belt). Make sure no tools are in the dryer cabinet.
23. Rotate the drum clockwise a few revolutions to align the belt and reinstall the rear panel.
24. Hook up the door status wire before you set the front cover and install the 2 screws,

We previously replaced the front drum felt seal and the tumbler glides, the belt and both drum rollers.

I received my ordered in less than a week. It was great. The day I got them I remove the old burners and replaced them with the new ones. It took me about 3 minutes total. I was then able to cook my Christmas dinner with out any problems.

First I unplugged the dryer. Then I removed the two phillips head sheet metal screws near the bottom of the front panel at either side, swung the panel out from the bottom until it unhinged at the top for removal. I disconnected the wire to the door switch and placed the front panel out of the way. Next I unbolted the top from the side panels by removing the single bolt at the front top of each side panel. This allows the Top panel of the dryer to be raised enough to remove the drum. I slipped the drive belt off the back of the drum, lifted the top a few inches and removed the drum. Next I removed the face plate of the blower channel to get at the squirrel cage blower and disconnect it from the motor by removing the outer snap ring from the motor shaft and then used pliers to remove the spring clip from the hub of the blower cage allowing it to slide off the shaft. There was a second snap ring to remove behind the hub. With the blower off the 3 screws holding the blower channel to the motor mount were accessable and able to be removed along with a couple of scews holding the air channel to the dryer base allowing the whole assembly to be moved out of the way to get at the motor. Two more screws at the motor base were removed to free the motor. Three color coded wires were unclipped from the motor and it was out after removing the drive belt from the pulley. Getting the pulley off the old motor after 29 years of service proved to be the most difficult part of the repair. Had to heat the pulley with a propane torch until the glue holding the allen head set screw decomposed enough to allow me to break the set screw loose. Releasing the spring clips holding motor to frame was easy using a large screwdriver to push down in the end recess of the clip while prying against the frame. Reassembly took less than an hour. The color coded dots on the electrical connector block were identical to the original motor making the electrical reconnection a snap (These dots were clearly seen in the photos of motor on the PartSelect website so I knew I had the right motor). The drive belt reinstallation was a little tricky as you have to spool the belt correctly around the pulley then put the drum back in 3/4 of the way and start the belt on the back of the drum and work it forward about 5 inches to its running position. Rest was easy, no parts left over and it works like new again.

The ignitor is easy to determine if it is defective. When you start the dryer and the ignitor does not glow , it is bad.
The replacement involves unpluging the dryer, opening the control access door ,the removal of one screw, unplug the bad ignitor, plug in the new ignitor, reinstall the one retaining screw, plug the dryer back in, check for proper opperation of the ignitor, and close the close the control access door.
Very easy

Frist I removed the front cover panel via removing 2 screws. Second I disconnected the door switch wires. Third I removed the 4 screws that hold the drum onto the rollers and guides that allows access to the blower wheel assembly cover. Fourth I remover the blower wheel assembly cover to gain access to the blower wheel. Fifth using the retaining removal tool removed the retaining ring from the shaft then removed the blower wheel using plyers. Then reassembled all of the parts and enjoy a quiet dryer again.

Thank you parts select!!!

Piece of cake. Used flat screwdriver to pry out female part on cabinet side, same with the male part on door. Every new replacement part was tight and operated like new. Thanks Part Select, you'll be forever on my list of online parts buying.

Getting to any of the parts in the Maytag dryer is easy. Tip the dryer back and slide a 4 x 4 block under the front edge. You remove the whole front panel after you remove two screws at the bottom corners of the front panel. You need to tip the dryer back to get a screwdriver on the screws. Swing the front panel up to release the top of the door panel from the top. Watch the short wires to the door switch. Unhook the door switch wires and move the front panel out of the way. The timer on the top is accessed by re-moving two screws along the top edge. There are four screws. Remove them all and tip the top of the front panel forward. You then see that two screws hold the panel and the other two screws just hold the trim.

The dryer started normal. The drum motor run when the start button was operated. The fluff cycle operated normal to indicate the timer motor was OK. On the dry cycles, the igniter heated up. The gas came on. The dryer run for some period of time and then the flame went off. The thought was that the low temp cycle thermostat sensed the dryer was hot and thus switched over to time the cycle to its end. However, the low temp cycle thermostat tested good with a meter when the sensor was removed from the dryer and heated with a light bulb. Burnt contacts in the sensor were a possible problem. I also though the radiant sensor may be bad and not recycling after it got hot. After time, the igniter would cycle on but the gas flame would not come on. I thought the radiant heater might not be tripping the secondary coil on the gas valve. The gas valve coils tested good. I was checking them cold after the dryer had cooled down. I ordered a number of parts.

I got lucky and did a test on the coils while the dryer was still hot. One of the coils in the dual booster holding coil was going open when hot. When cold it had enough continuity to let the gas valve cycle on once. After the coil got warm it went open and shut the gas valve off. When the coil did cool off, it again had continuity. I was about ready to trash the dryer when I finely found the problem. I am happy I persisted and worked the problem through to a solution. I purchased several extra sensors but saved money in the long-run. I rate this problem at the high end of complexity for the do-it your self home owner to solve. The problem was an easy fix once the real problem was found. Only 4 screws and 3 push on wire connectors (two were on the front panel for the door switch).

Checked four thermocouples all showed continuity with my multimeter so they were all good. I'd read that the coils commonly went out and that these were the symptoms. Hey, it's very simple in there. Not much else could be wrong. I had a Maytag repairman come out. At first he said the problem was a blocked vent. I knew he was wrong. Then he said one of the thermocouples went out. It was $80 for him to come out. It turned out that his second diagnosis was wrong too. To repair the dryer by Maytag would have cost me $240. I gave him $80 and bought the coils for $37. They are EXTREMELY easy to replace: two screws held a bracket that held two coils. With the bracket off, I took off the old coils and slid on the new ones.

First I removed the front panel on the dryer. While the dyer was running, I noticed the igniter did not turn its normal amber color and ignite the gas supply. I then disconnected the wire to the igniter and removed the screw holding the igniter in place. Next I replaced the igniter, tightened the screw and reconnected the wire. Finally, I replaced the front panel. This is a relatively simple repair.
