Does this indicate the timer? Dryer works fine just we have to manually open the door to stop it.

Same malfunction on timed dry as well as automatic?  If so, then the next step would be to open the control panel and test the continuity of the timer motor; also test whether or not it's getting 120vac while the dryer is running in timed dry mode.

Since the dryer runs just fine, and it's a dial, that probably means water/lint built up until the point that the dial got clogged. I'm unsure as to how the dial itself works although I'd guess it uses some kind of clockwork mechanism like a coo-coo clock to operate on and when it gets to a certain point it'll hit a switch, trapping the dial into one spot and tripping the control system to stop running the washer.

You can probably open it up and vaccume it out. Worst case scenario, you blow $30 on a new dial or better yet, get a fancy schmancy extension cord, plug one end into the wall and the other end into an electric timer and then plug the washer into an electric timer if you don't want to touch the internals. I don't see any harm in just leaving it broke so long as it turns off somehow before things catch on fire or melt.

:laffinatchoo:  That's gotta be one of the goofiest explanations about how dryer timers work that I've ever heard!  Good one!

:P

I DON'T KNOW HOW THEY WORK!!!! :(

Once I take something apart it sticks with me.

That, and I have momentary dyslexia :P.

I wanted to say thank you for both of your replies. I will check both suggestions and be posting back tommorrow!

Ok...took off the back of the timer portion of the dryer.   Geez, I didn't think there was so much to a dryer :shock:

I do have a little electrical experience, so i started poking around.   It does appear to me at first glance that the timer motor is bad.  I am getting 120vac probing the two red circle points in the attached picture.    The picture is blurry but the red points both feed the timer motor at the green point.

While I was poking around, it also appears that the start button is stuck to constantly closed.  It appears in the schematic that it should be momentary.  I have disconnected power and tested the button just by itself and it appears to be stuck.  Maybe two seperate problems?

Thanks for everyones help!

What's the answer to this question?

 

Your photo was too blurry to be useful so I deleted it.  You're welcome to post a better quality image. 

The timer motor wires are easy to identify:  they're the only two wires coming out of the timer motor! 

[cypsteel]

Yes...I have been testing on timed dry to eliminate moisture sensors and tempature sensors.

[cypsteel]

So should I buy the timer and a start button?

[Samurai Appliance Repair Man]

Check the power resistor.  If it's good, replace the timer.

I know this is an old thread, but I am having a similar issue with a dryer I bought used. 70 series Kenmore. Dial doesnt move in auto cycles. Does stop running if I manually move the knob. The Timed dryer DOES work and cut off appropriately. I've read that it's a temp or moisture sensor or something like that, just need to know what I'm looking for so I can replace it. Besides the auto cycle not stopping, the dryer runs perfect. Thanks for your help.

Goat314 need the model numbrer off the dryer, open the door and get it.  Is the dryer heating? If not it will advance in timed but not automatic.  If it is heating it will not advance in auto if the air flow from the dryer is blocked....If it is heating try it with the vent off to see if it is a blocked house vent problem first..

Model # 96573120

Dryer heats perfectly, just doesn't advance the knob in auto cycles.

Knob does not advance with the vent off.

[Pegi]

The dryer advances in auto thru the heat curcuit and the resister beside/on the timer, check the resister to see if it is defective...

[Samurai Appliance Repair Man]

Good advice on the power resistor. Could look like this or this.

[goat314]

Thanks very much, funny enough, it was as simple as 1 of the wire clips coming loose from the resistor. Works perfectly now.

Welcome....;)
