Maytag DE808 Dryer Won't STOP Drying!

[NancyorEd]

Hello again!

I finally got Ed, my better half, working on the dryer that wont' stop drying again! (See posts # 470726, 470729, 470738, 470734, 470756 & 470780)

Following all of your helpful advice, Ed first checked the unit for proper grounding.

He also checked to make sure that the ground wire on the dampness sensor was correctly grounded.
Both of these grounds were tested using a 100 watt light bulb.

Then, Ed checked the wiring to make sure it was all hooked up correctly.

He also tested the bell with a jumper, and it seems to work just fine.

Ed then purchased the following two items:
1. A new edgeboard connector (included new Capacitor), PN 3-4980 same as 304980.
2. A supposedly good, used control board, PN 3-4478.
We used your 90 second test on Damp Dry, but it still doesn't work.

So far, Ed has accomplished nothing. The good news is it will be easier to Christmas shop this year, since we seem to be spending a lot of our Christmas money on the dryer!

First, does anybody know what the purpose of this neon lamp that is on the control board is? Ed has tested the bulbs on both cards (the original and the used card we bought), but so far, they don't light up.

Secondly, are there any resistors on this control board that are notorious for failing? Specifically, the 2.2K resistor underneath the capacitor?

Third, are there any connections on the panel switches that Ed should check?

Ed has been trying awfully hard to make my life easier, and I am hoping somebody out there might have run into this problem.

I appreciate any help you can send our way,
Nancy

Is the dryer still properly grounded

if the ground wire has become disconnected the Electronic Dry Control will no longer work. PAT COFFEY

Light Bulb

Light bulb may be a bleed-off for the large black capacitor. Maybe for safety purposes? It might light very briefly or not bright enough to see if it bleeds off over a longer time. These are guesses. Check your moisture sensor. You can take it out and clean it. I've gently pried the strips up and cleaned the dirt out underneath and pushed them back down. I know, sounds dubious, but I've done it. May not be you problem. Wiggle all your connectors with some needle nose to make sure you've got good contact. Your cool down thermostat may be stuck closed. It would show low resistance. Just some ideas. My service manual isn't with me.

Thanks for your suggestion. Our dryer has a separate ground wire connecting to the cabinet on the upper left hand side, where there is a factory-equipped ground screw. Ed has tested with a 100 watt test lamp, and found all areas of the cabinet checking out to be grounded properly.

Another thing that maybe causing the problem is dryer fabric

The sensors in the baffles of your dryer drum maybe coated with softner sheet residue and that too will render the EDC inoperative. The better brands like Bounce are supposed to be formulated not to cause this problem but if you are using a cheap brand...who can say. Maytag's sensors were noted for being suceptable to this.

Nancy,

Check to make sure the paperclip linkage between the soleniod and switch is still in place. Here's a pic of my HDE-808 pointing to the linkage via the yellow diagonal line. If it's not in place (they break after several decades of use and a gazillion cycles), the dryer will continue to run. However, if you select "Damp Dry" with an empty drum, you should at least hear the solenoid "pop" and attempt to shut off the dryer.

DE808

The first thing I try is to disconnect the wire at the control area that goes down to the sensor strip, if the dryer stops on damp dry you know that the sensor or wire is shorted some where. If this doesn't work try to get a copy of the service manual and go through the other check out procedures. These can be a little frustrating to fix but it is fixable. MT always suffered more with electrical problems on thier washers, dryers and dishwashers than the other big companies because they didn't make these parts themselves. Whereas the mechanical parts of the machines that they did build always faired much better.

Years ago, I bought a DE608 that was supposed to work fine. It worked too fine, it wouldn't shut off!
I replaced the board pictured with a new one, and it worked after that.
