Dryer won't stop!

[NancyorEd]

Hello everyone,
Now that my classic Maytag is up and running like it is new,
(See Thread Number 29612 - Maytag A806)
it is time to make the matching Dryer also work at peak performance. Don't get me wrong, it dries stupendously.
The problem is, it doesn't know when to stop! It no longer dings to let me know a load is done. If I am not paying attention, it would continue to run ALL day and ALL night!
My intrepid husband thought the problem might be the thingie pictured below. We even found a used one on eBay, but it didn't help.
I am counting on your collective wisdom once again! Can anyone help?

That't the control board, it COULD be the problem.
I know I'll get chastized severly for this, but make sure your dryer is properly grounded. I ALWAYS run a seperate ground wire, from a cabinet screw, to a cold water pipe.
Make sure the paper clip looking thing that connects the solenoid to the switch is connected.
Set the control to DAMP DRY, with nothing in the dryer, and turn it on. It should shut down within about 90 seconds. See if the solenoid energizes.

Which version?

Is this a "Halo of Heat" dryer (Models DE806 or DG806) and has the lint filter in the back of the drum or is it a later "Big Load" style dryer (Models DE808 or DG808) with the lint filter just inside the door opening?

If it's the 806 dryer, make sure it's properly grounded. If it isn't, it might run without shutting off. Also, on the HoH dryers, the bell clapper actually has to be intact to shut the thing off. IF it got bent or damaged, it won't chime and it will keep running.

I know less about the later 808 dryers.

What are we working with?

There should be a rather large capacitor attached to outside of the electronic control unit box. Most were electrolytic capacitors until recent years when they got smart and used film capacitors, which will last pretty much forever. The electrolytic caps are known to go bad after 20 years or so. Whether it's the problem or not, I would replace it because it WILL soon fail due to age. Replace it with a film capacitor of the same microfarad value. You can go higher on the voltage rating (never lower!!).

It should shut down within about 90 seconds.

HOH's should shut down between 7-17 seconds. Perhaps you're thinking of SOH's. They take considerably longer.

 

[goatfarmer]

I probably am. I know if it runs after a minute or so there's a problem.
The control board pictured looks newer than HOH.

Our dryer has the lint trap in the front, and is Model #DE808. I open the door, look down and pull the lint trap out of the front curved rim.

I will share your ideas with Ed as soon as he gets home, and let you know!

Thanks for your early posts!
