Another ADC Dryer problem

[Ronald]

Walked in mat this morning and see a dryer running (adc25) so I go to take a look here is what I find.

Dryer is turning display shows no time left,there is no heat so i try turning off power to dryer and turn it back on and dryer starts turning again. I tryed this 5 times and get the same thing.

any ideas?
Ps: hope this is clear this time

Another thing I did put a quarter and the heat did come on

Sounds like the motor contactor contacts are sticking closed. It should be located in the rear of the dryer. According to the parts manual the part # 132431 which is no longer available. The new cross ref # is 882386 which is 126 bucks list. Although I haven't seen one of these dryers in many years I would assume you could use a 132475 contactor which may require you to drill 2 holes to mount it. Price of contactor about 15 to 20 bucks.

Let us know what you find out.

Mark is definitely on track, as usual. The fact that a quarter fired up the heat indicates that the normal timing mechanism is working fine. The dryer is running because the motor control switch (the contacter) is frozen in a running position. This happens when the contacter points corrode and burn out over time. I had one a few weeks ago in an ADC285. I didn't even notice until a customer pointed it out to me. So many dryers were running that I thought this one was just another working dryer.

Replace the contacter and it will be fine. Marks suggestion is to dump the high dollar contacter and use a generic contacter instead. Its worth the extra effort to save the bucks.

The only thing i see on the back is the main wire box and the flapper box would you be talking about in the control box??

Yes, it should be in the control box.
