DDC6400PBL Whirlpool Dryer - Instructions

unknown
25 year old GE dryer started making strange scraping noises when running. This even when there were  no items in the appliance. Turning off the gas, and unplugging the power I disassembled the unit to find the nylon drum bushings worn down. Especially the felt like material under them that I think dissipates friction heat. A quick order to GD for the parts, 2 days later I had the part installed, and noise was gone.

Gas valve coils need replacing I followed parts select.com video on YouTube and had no problem. It went exactly as the video followed parts select.com video on YouTube and had no problem. It went exactly as the videos showed!

I opened the top,by removing the two screws inside the door
on the top. then removed the frount by removing the two 5/16 sheet metal screws inside facing the frount. then pulled the drum out and replaced the berring. Cleaned out the lent from the motor and duckings. Then reasembled.

1. Unplugged from wall, turned off gas and opened top cover. 2. Removed two wire clips for door switch and unscrewed front cover (2 screws inside). 3. Removed front cover and moved to side. 4. Unplugged connectors from coils. 5. Unscrewed coil screws. 6. Replaced coils and tightened screws. 7. Replaced front cover, tightened screws and reinstalled wire clips. 8. Closed top cover, turned on gas and plugged in power. 9. Dryer fired right up and made heat.

Backwards to start- here's the correct way.Disconnect power and vent hose-tip onto front-remove bottom plate allowing access to bottom of dryer and the belt pulleys-remove the small plate in center and under that is a C-clip holding the drum shaft in place-remove the clip and washer-sit dryer upright - open the door and remove the 4 screws under the upper lip which hold the top of the dryer in place-lift up top and secure or have someone hold it up.-inside the top front on both sides are 2 screws per side and there are 2 screws at the bottom under the kick area, remove all 6 of these screws and the front of the dryer will come off-watch the wires-with the front off you can pull the drum forward to allow installing the new belt. - hold the new belt in place with a couple of pieces of tape-reverse the procedure to put drum back together and then thread the new belt onto the drive pulley and under the idler tension pulley.- reinstall back plate, vent hose, power and you're ready to go have a beer.

This 10 year old dryer stopped heating. I knew a Maytag would have much more life left in it than that (even my Mom's lowly GE lasted more than 40 years!) so I was sure it could be fixed. Without doing any testing, I had just guessed that the glow bar was bad and replaced it. But that wasn't the problem - the old glow bar still had continuity as tested with my ohmmeter. So I dug in deeper and looked over the schematic posted on PartSelect's website. The glow bar would light up and then go out, but the gas valve never opened. After probing the two solenoid coils for voltage, I decided the primary solenoid was bad. This was confirmed when I took the connector off and checked with an ohmmeter (never do this with the wires connected!) and found no connection at all between the two terminals.
Ordering the new part from PartSelect was fast and easy and my part arrived in two days. The solenoid coil on this dryer can be removed from the gas valve without taking any gas lines apart - I don't know if they're all like that, but it's a great feature. The only hard thing is that there is no access door to inspect the flame like older gas dryers. You have to take the front panel off to watch it working, but that just involves the four screws around the door opening.
If your pre-Whirlpool Maytag dryer is giving you trouble, take heart! These are great machines that last long, are easy to fix, and parts are easier than ever to get with PartSelect!

First I unpluged the dryer,thenI removed the front of the dryer,spun it out of the way but did not detach the door wires.I then took the two skrews out of the braket that held the old coils,unpluged both coils, I replaced both as I did not have the means to find which one was bad.Besides, I did not want to visit the insides of the dryer for another five years. This was a snap and the parts were perfect and arrived timely.

and the problem wsa solve

bought the new coil valves changed out new for old, presto dryer works now

I looked on the internet for instructions to take the dryer apart,took the parts out one at a time ,and replaced them.It was easy and it made the dryer quiet again.I could see the obvious wear on the parts.I was happy to save the money a new dryer would cost.

When you open the door to the dryer there are 4 screws you need to remove (2 on each side) in order to remove the front panel. Once I removed the front panel I then turned the dryer on to see what was happening inside. The heating element was turning orange with a glow but the gas wasn't igniting. After looking on-line I figured my next option would be to replace both gas valve coils (one is 2 terminal & the other is 3 terminal). Once you have the new parts & are ready to install them unplug the dryer. All you need to do is first, unplug the 2 plastic sockets that feed the electricity to the coils (they have wires attached to them) unscrew the bracket that holds the 2 coils in place, pull the old coils out & put the new coils in, replug the electric plugs, re-attach the bracket that holds the coils into place, plug in the dryer & turn it on. Test it without the panel on so that you can see that the gas ignites. My husband was very happy when I told him I repaired the dryer - beats paying another repair man.

Removed Two screws took out the coils put in the new ones
I ordered one day and got them the next day. Thank you partSelect For the quick service.

took off bottom access panel replaced both electronic coils web site helped diagnose problem

Pulled the top of dryer off. Separated the door from the drum seal or gasket, slipped the belt through, put the drive belt on the motor and then put it all back together.

open the front of the dryer, open the back access panel, remove the old belt fragment, pull front cover away from bushing surface at the front of drum, drape new belt around the face of drum, match location visible as the track of old belt, reroute belt at the motor and install tensioner in the proper way, reattach front cover, install back panel, done.
