Thanks for your timely response.
Unfortunately, I don't have a temp guage on site at this point and the dryer is still apart.
This dryer is part of a stacked set at least 12 years old.
I agree, since there is only one heating element thats not the problem.
The venting has been the same through out its use, so I don't think it's the venting, plus I have a full size exhaust.
I have a local parts house and I'll try testing and replacing the high limit switch.
I appreciate the help.
Any comments on what brand of a stackable combo you/ve seen less repairs for?
as far as stackables go this is a good one. I believe the thermostat should take care of your problem. at least its the cheapest part to try first .it is around $30.00 if this doesnt work come back on and we will check other things . please press accept so they will pay me for my time. if you need more help after as long as you dont close the question you can come back at no additional charge and I will be glad to help further, thanks Bryan
just a follow up comment.
I replaced the thermostat and the dryer is back to normal,
Thanks again for the help.
