'75 DE806 not shutting off after cool down

[bradfordwhite]

Thanks for that Glenn.

I actually had a 806 dryer I picked up when I was collecting in 2002 with that panel and timer. But was so overwhelmed with all the appliances I never got to check out the timer. I had no idea it was entirely electronic.

Now, how to fix the dryer at hand? Why won't it shut off and are timer parts still available for these dryers?

The stair step above still would say that the cool down sensor should be the issue. When it’s cold there is no continuity on the new part.

Ben, where is the electronic control capacitor? I’ll test that next.

 

[swestoyz]

The capacitor is mounted on the electronic control assembly itself, vs. the 08-12 series being part of the harness connector. It would be difficult to test with it in circuit. Any chance you could take a few pictures of the control? I'd like to see the condition of the terminal connections.

Is the dryer dinging at all when attempting to dry a full load on either Regular or Perm Press, and not shutting off? Or has it stopped dinging completely? If you start the dryer can you manually shut the dryer off by moving the slider on the back of the switch towards the solenoid (use an insulated tool for this test)?

The replacement cool down stat is acting normal if open when cold.

It runs the full cycle and dings, clothes are dry, but then it still goes into the endless cool down and never shuts off. Here are some pics of the control.

Looking A-OK

Before mucking with the wiring, test the shut off slider on the back of the control switch.

Is the shut off slider the little clip the paper clip attaches to? If so, it moves, but it’s a little crunchy.

 

[swestoyz]

Yep, it's the brown/dark colored wafer that the paper clip is attached to.

It shouldn't be crunchy. Did it shut the dryer off, or take several cycles (move slider to off, dryer doesn't turn off, press the control knob to on, repeat)?

As I mentioned earlier, these switches are starting to become the Achilles heel of the electronic control HOH dryers.

You need a selector switch

I just cleaned it out with some contact cleaner. It’s sliding nicely now. Let’s see what happens.

 

[marks]

Same situation. It dings, shuts the heat off and then runs indefinitely. The slider slides properly now though.

 

[swestoyz]

Even though the slider may be moving freely, doesn't mean it is actually shutting the machine off by opening the contacts within the switch.

If you manually move it to off while running, does the dryer turn off? At this point I'd say you need to start searching for a replacement 302528 switch.

Has anyone ever done an autopsy on a failed switch? Or have a photo of what the inside looks like?
I'd be interested to see how it is that they fail... and whether they might be rebuildable.

 

[marks]

Sliding the slider manually turns off the heat but not the motor. The only thing that turns it off is opening the door.

 

[swestoyz]

Time for a new switch.

 

[marks]

Yes I guess so... I’ll switch these out for the time being. The washer needs damper pads. At least these machines are most of the way there and they look good!

 

[swestoyz]

Absolutely agree they are worth it for the long haul. I’ll check my stash of parts tomorrow and if there are than one switch in the totes I’ll shoot you a PM.

Since the electronic dry control wasn’t working properly on my Maytag DG606, I ended up converting it to a DG306 timer dryer. Haven’t had any issues since I converted it to a timer dryer in 2019 and has been trouble free since then.

 

[marks]

Ben, if you do have the switch, let me know. I’ll send you back the old one just like the swap we did on the last one.

 

[swestoyz]

Hey Mark, my original stash is now down to one switch and I'd like to hold on to it for a future project. If I run across anymore I'll let you know.
