Quick rundown: My wife and I went on vacation and when we came back yesterday, our Kenmore Elite (model# 110.73932102) Dryer was having problems. When we hit the start button, it would only run when we were holding the button down. When we let go it would not keep running...

So after a few hours of research on the web, it seems this is a common problem with dryers with the "Evenheat" feature.

So I opened up the dryer and found the board was burned up in certain places. A resistor looked like it had too much current through it and the two capacitors were blown. Has anyone taken pictures of their bad boards?

Here is a picture of mine (with the bad parts highlighted)


Has anyone ever tried to fix the evenheat board? I want to try and fix it tomorrow at work (see if I can get replacement parts and rework it).

I saw in this thread that Jake has old boards that don't work. Do the bad boards look like mine here?

Yup , the boards i have changed look burned like that.

I always stock that new board on my truck stock, as Techs we have to change the whole board, You can try to just repair the board, could work, i have never tryed, i always change the whole board.

Thanks for the quick reply!!

Do you know what causes the boards to burn up like this? Or is it just after a year or two the board dies? We bought our washer/dryer in June of 2003.

Are there any other tests I can run on my dryer? I saw on the famous "evenheat" page: http://www.applianceaid.com/evenheat.html that you can do a Factory Test--but I do not have a wrinkle guard knob on my model. Do you know of any tests for my model?

Nope, i sure don't know what causes these boards to burn out, i don't know of any other tests you can run.

Sorry, i can't be much help with that, i just replace the boards when they go out.

I've seen many of these fail, but only one with that kind of damage. You could try repairing the components, but what made them fail? Something external? Out of interest, you didn't hold the start button down to keep it running, did you? The motor relay is designed to carry the current to run the motor, the board isn't. I once came across one where the customer duct taped the start button to keep it going!

There should be a "tech sheet" in the console where the board is, detailing the test procedure for your model.

Oh man :shock: My wife did that! I took the tape off (it ran for about 15 minutes) so I could examine it more closely.

But it was doing the same behavior before and after she taped the button. Do you have any insight into why the board failed in the first place? Why the dryer stops right after you let go of the start button?

Where inside the console is the tech sheet? I took apart the very top (Where the dials and start button are) and I didn't see any sheet.

Thanks for the info!

Hi,

**Where inside the console is the tech sheet? I took apart the very top (Where the dials and start button are) and I didn't see any sheet.**

Thats usually where it is....unless someone has taken it out

Normally rolled up inside the consol.

I once trained a lad who had previously worked as an electronics tech, he did some investigation on a failed EH board and came to the conclusion that the diodes (some kind of bridge rectifier) weren't up to the job. The "original" EH boards fed an AC relay, Whirlpool came up with a kit to replace them with a revised board and DC relay.

My recollection of how this works is that the board energizes the relay which then feeds the motor. Holding the button in will run the motor until either the PTS (push to start) button gives up or other components on the board give up. Neither is designed to take the motor operating current for a sustained period of time.

For the tech sheet, look at the back of the console section, where there is a notch in the top of the machine - its usually folded up in there.

Just wanted to let everyone know that the dryer is now fixed! I ordered a new part from repairclinic.com and got it very quickly. Popped the new board in and the dryer is working fine.

Thanks for all the help from the people on the board. I wish I could have gotten Sears to pay for it. But after 3 hours of making phone calls I was fed up dealing with their B.S. and decided it wasn't worth my time and paid the $100 to get the new part....:?

**Popped the new board in and the dryer is working fine**

Glad to hear that

jeff.
