Kenmore 70 series - No heat, won't shut off
 
Dryer's timer dial DOES MOVE on timed cycle...but will not shut off (it will shut off if I manually move the dial to "off"). I have not even tried it in "Automatic", as we never use this mode. This issue seems to have happened at roughly the same time that the heat in the dryer quit working (a couple days ago).
I was going to order a new timer...but thought I would run it by some folks more knowledgeable than me before I do.
Here is a link to the parts page (links in blue on the left side), if that helps:http://www.********************************.com/partsdirect/getModel!retrieve.pd?modelNumber=11060722990

Can you clairify a few points.

You say the timer moves but to shut off the machine you have to manually move timer to off. What happens if you do not move it, does it go to off and stop, but not shut off the machine? Does it go past off?

When the heat failed what did you do to fix that?

I think the timer is likely the problem and replacing it might solve your problem, but if you want more info let us know the answers to the above, and also operate the machine on auto just to see what happens and let us know those results also.

I'll do it and post back. Thanks.

Ok...after a little further investigation:
The timer dial does move toward off, as I said initially, but seems to stop moving just ahead of the off position. It will only shut off when I manually move it forward to off...or open the door.
In the auto mode, the dial does not move and it does not shut off until I manually move it to the off position or open the door. I put a damp towel in tonite and it ran till the towel was dry...but dial never moved and it did not shut off.
I still have not addressed the heat issue. Still no heat.

Ok, well it sounds like the timer so if you want to try and fix this I suggest you go ahead and replace it and see if that fixes the timer movement problem . You should check continuity on the thermal fuses and thermostats to see if that is the source of the heat problem, and also ohm out and check the heating element. If you find the problem in them, replace the faulty part at the same time as the heater. If they all check out, see if the new timer will fix both problems.

Do Let us know what happens.

Heating element was bad...so ordered a timer and heating element. Installed the timer tonite. No change: advances toward the "off" when in timer mode, but stops advancing just ahead of it...and just keeps on running. Any ideas?
Heating element will be here in couple days.

sidfink43 08-21-2009 06:06 AM

Let's see what happens when you put in the new heating element. Try it after that and see how the machine performs. Replacing the element will reduce the number of things contributing to the problem.

Let us know what you have then. Thanks

Replaced the heat element...and now everything works fine. So...put the old timer back in and dryer continued to work perfectly well. The outfit I bought the new timer from was willing to take it back. I'm not sure why the problem of not shutting down...while on the timer rather than auto ...was remedied by replacing bad heat element. Thanks very much for the help you have offered, sidfink43. When you have time...can you give a brief explanation of what might have been going on?

sidfink43 08-30-2009 06:37 AM

Well, glad the new heating element fixed it, and that you were able to return the timer.

Here's what I think was going on.

In auto mode the timer will not advance when the heating element is on. This is how it attempts to set the drying time to match the time needed to dry the clothes.

The thermostat cycles the heating element on and off, and off and turns it off when it reaches a certain temperature, at which time the timer will then advance until the heating element comes back on. Since the element was not heating (the machine did not know this, it thought it was heating), the dryer never reached a temperature for the thermostat to cycle off the heating element, so the thermostat never turned the element off so the timer never advanced.

In timed mode the timer moves independent of the hearing cycle. It sounds like the timer reached the cool down section and then stopped because of the problem with the heating element.

Thanks for updating us. Good luck going forward with your machine.

Same problem
 
I have the same problem! Can you tell me what the part number for the heat element. Also was it easy to replace! Is there a link to instruction on how this was done.
THe model # for my dryer :11076712694 which is also the Kenmore 70 series.
Thanks for any help that can be offered.
