DDC6400SBLAD Dryer - Instructions

my two twin boys Mike and Curtis age 14 did the repare they toke of the front of the dryer then the top put the belt around the drum then put the top and front back on then went to the back and removed the panel and put the belt on the pulley then set the tension wheel then put the back cover back on
the repair was easy I watched to make sure they did it right and did not have to tell them how I am very proud of them they do great work
finding the part was easy and it was here the next day after I ordered it and it was only sent 3 to 5 work days. You guys have a great web site and fast shipping thanks for the good work!

I opened the vent system (screwdrivers to loosen screws) and used the shopvac hose and my hands to clean out what I could. I also snaked the shopvac hose down into the dryer and removed clogged lint. Then I just replaced the lint filter.

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 lower rear inspection plate to see what the problem was.
next i removed the screws in the front top panel.
next i lift the top back,the rear hinges held it in place.
next i removed the bolts that held the front panel in place,but before i removed the panel i removed the wires that were connected to the front elements and disconnected then,
next i removed the front panel,then i place the new dryer belt over the dryer drum,but first you have to rise the drum up a little to get the belt under it.
next i put all the front panels back in place,make sure you reconnect the wires that you removed earlier.
next i moved to the back panel, there i position the belt over the dryer drum,then i place the belt over the motor drive pulley, then i pull down the tension bar roller to the left and place the belt over it.Then i replace the rear panel in place.plug in the power core and turn it on. finished. After over 35 years this is the first time i had to replace the belt,matter of fact this is the first time i had to replace anything on this dryer, washers will that is a different story. but the dryer runs great maybe for another 30 +years LOL.

Easy as 1-2-3. I took off the top hinge screws in order to lift up the top of the dryer.

I then took off the front dryer piece with the door intact. The lint filter was in the front door section.

I released the wiring clips to the front of the dryer and lowered the front of the dryer down gently. there is enough slack with the wiring if you disconnect the wirre clips.

I removed the old broken belt. ThenI gently lifted thr dryer drum enough to slid in the new belt with the ridges down. Look for the old belt line (worn area on the drum) and slip the belt up on the drum to that point.

Then I replaced the wiring with clips and put the front of the dryer back together.

Going around to the lower back of the dryer, I unscrewed the back plate where the exhaust comes out. It was 8 screws with a socket.

Once the back was off, I pulled the dryer pully to the right and fed the reamider of the belt through both pulleys ensuring that the ridged side was on the correct side of the pulley. The pylleys match the ridges on the belt. I rleased the tension on the movavle pulley and it was done.

All I had to do was button the back up and do a "dry run" I quick have the drum a half roation from inside the drum with the door open. Then it was all gravy. I was done and saved myself a good deal of money. Look on the net for pics to make thing easier for you. There are people out ther who will NOT charge you for this info.

Removed the rear access panel (8 - 10 bolts), checked the pullys. Opened the dryer door, removed 4 allen screws at top and lifted the top of the dryer (like a hood on a car). Removed a screw (phillips) on each side (inside) pulled open the front and worked the belt around the drum. Placed belt onto pullys, plugged in checked for proper rotation of drum then unplugged and installed screws and bolts. - Fairly easy, saved a bunch from a service call. I also found 15+ years of lint inside the dryer. Vacumed and cleaned the inside -it even dries faster! Sorry Honey - No new dryer this year - Now can I go hunting?

snapped in new latch

It was super easy, done in 5 less than 5 min. Thanks Parts Select. Parts Select made it easy to find the replacement part by posting pictures. Thanks

door handle just snaps right in and the lintfilter is a no brainer. thank you very much partselect keep up the good work

I checked the power (OK) and removed the four screws that held the timer/controls (upper panels) cover. This revealed a schematic for the dryer that enabled me to determine the door swich was probably the culprit. I pried out the old switch and, sure enough, it was always open (checked with multi-meter). I found the replacement switch easily using the dryer model number and "door switch" search string. Ordered Sunday night, the part came on Tuesday and took 2 minutes to install (no tools needed).

Removed lower front cover of dryer, located coils, removed old coils by disconnecting the wires and removing the hold down bracket screws. Pulled the old coils out replaced them with the new coils by aligning the index pins on the coils with the holes in the bracket then reattached the bracket and plugged the wires into the new coils. Then closed the cover on the front of the dryer. Dryer now ignites and stays on to heat up and dry clothes.

Replaced both Coils. Purchased M Series coils much less expensive buying coils together instead of seperately. Problem solved.

I changed the two coils for the gas valve and the dryer is now working fine thanks

Shut off gas removed gas valve. Removed the coil retainer and installed the new coils. Reinstalled valve and checked. Found dryer worked fine.
