MGD6400TB0 Maytag Dryer - Instructions

I tried to follow directions followed by others on this site after diagnosing the problem via suggestions provided by users. I have a Whirlpool Duet dryer from 2002. We've had problems since moving about 3 years ago. I removed the front panel (lower) by unscrewing the two bottom screws (1/4" sheet metal screws). Then I took out the lint screen and the metal tube/contraption immediately beneath to get access to the area where thermistor is located. See the drawing/chart to help you locate this. It's really easier than it seems. Make sure you have the chart/drawing for your model - it makes difference! The thermistor came out pretty easily with a nutdriver that has a swivel offset shaft. Ask your hardware store tool dept. about that one. Put everything back in reverse order of course and test either with/without the front panel re-attached. In my case it fixed at least part of the problem. I was able to get clothes almost dry with most settings but I have yet to install the moisture sensor to see if that helps in addition to the internal-bias thermistor. I am the kind of person that does one thing at a time so at least I now know the thermistor was bad. Good luck and hang in there with your own repair. It's a lot cheaper even if it takes you longer to do than a pro.

Initially we thought the problem was the igniter, so we ordered an igniter kit. Installed it but was unsuccessful. We then went on the websight and read further, about 50% of dryers with no heat but working had a problem with the thermal fuse.So we ordered the thermal fuse installed it, which was very easy, and success. Once the problem was diagnosed properly it was fast and easy. Recommend looking at the statistics for specific problem.

After replacing all the other fuses and sensors I finally replaced the Radiant Flame Sensor and it is working perfectly.

After replacing the other parts and the heat still not coming on I read somewhere that the Radiant Flame Sensor is a normal closed circuit and when I checked with a meter it was open. I would have saved a lot of time and money if I had read that earlier.

I removed the front panel of the dryer by removing the 2 screw that secure it at the bottom and pulling upward to disconnect the cover at the top. I then removed the two screws that hold the metal cover that secures the 2 elements in place. I disconnected the wire plugs from the 2 elements, removed the 2 elements and replaced them with the new parts making sure to place them in the same positions as before. I then replaced the housing cover and tightened the screws. Then I replaced the front cover of the dryer.

Very bad design to keep door shut but very simple to fix. Just screw bad strike out and screw new one end. Whirlpool should have gave extra when you buy this type dryer.

Opened front panel .Tested both coils on gas valve.
Found no continuity on one of the coils. Replaced coil,
dryer works like new.

1. Shut off gas and disconnected dryer.
2. Opened cabinet. Easy sheet metal screws and fairly obvious how everything goes together. NB: You'll need a block (or a helper to hold things while you run to look for one) to hold the drum while removing the front.
3. The motor is connected with a single harness, so wiring is a snap.
4. Removing the blower wheel from the back was hard. I braced the motor shaft and turned with all the leverage I could muster, but it was stuck. Plan B: Recip saw to cut the shaft. Motor comes out one side and the fan comes out the other.
5. The fan, of course, was unusable because there was still a piece of motor shaft stuck in the thread. This is why I had to spring for a new wheel.
6. Put everything back together and receive wife's adoring praise...

Like another reviewer's repair story, I decided to take the door apart. It was too difficult, at least for me, to get the faulty catch out without damaging either the the door or my hands. This is why I give it an "easy" rather than "very easy" rating and put the total repair time at a half hour or better. I also decided I wanted a second person to help - not with getting the door apart or putting it back together, but because a second pair arms was very helpful in rehanging the door well. We removed the door (four screws), marking which side of the hinge needed to be flush with the actual dryer when rehanging. Then we took the door apart, which comprises another sixteen screws (four on each edge). We used an electric drill but I'm sure it could be done manually. We used needle nosed pliers to get the faulty latch out of that side of the door, then replaced it with the "back up" from the other side. Then we put the door back together and carefully rehung it. Done. We did decide that, in future, all kids (we have three boys) slamming the door would be severely beaten. Pushing the door until it's against the dryer, then PUSHING (as opposed to slamming) the latch ONTO the catch pin on the dryer is obviously what was intended. However, I've learned not to count on my boys being particularly conscientious, so I'd ordered four replacement latches to keep on hand. This machine was delivered in April 2009 and I replaced the latch in April 2011. Based on this and our laundering habits, I'm sure the others will be used long before the dryer calls it quits.

Removed the broken catch with a pair of needle nose pliars and replaced it the same way. Took about 10 minutes. Saved a Service Call

Took out two front Panel screws and removed the panel. Removed Gas solenoid coil holding bracket by removing two phillips head screws. Disconnected the coil leads. and removed the coils. Connected the new coils to the leads and set in place. Replaced the holding bracket and the two screws. Replaced the front cover and the two front cover screws. Piece of Cake!

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.

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.

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!!!

Unplug dryer from receptial. Poped top off, useing thin bladed screw driver to push tintion springs, while pulling up on lid. removed two no 10 sheet metal screws, useing 1/4 nut driver, this removes loading door by pulling uo 1/4 inch. Removed twi NO 10 sheet metal screws useing 1/4 nut driver, removed front carrage system. Removed belt then tub.

Used two by four to hold tub up so belt could be put on, rolled tub to alline belt. Not bad for 70 Years young. Curtiss

Unscrewed the bottom panelof the dryer and located the thermistor through the schematic for my machine. Removed the old one and put the new one in the same way. No more E1 problems and all cycles now complete themselves.
