So, I've been looking around for info on this problem I've been having and I'm hoping you folks might be able to help. I have a Whirlpool Estate dryer, model TEDS840PQ0. It's coming up on being 5 years old. About 6 months ago, it started acting weird. It would shut off part way through a cycle (I would usually put the timer on somewhere in the middle on the autosense setting as opposed to straight timed drying) and the timer would just stop moving. At first it would fire right back up if I spun the timer and turned it back on, but it kept happening more frequently. I did some experimenting, and after a while I determined that the dryer would not start at all if the timer was in any of the areas on the timed drying setting, but would usually run fine if I put it on a higher dry setting of the autosense. Most times it would shut off at least once if not a couple times while I was trying to run a load through, but would always fire back up. About a month ago, it stopped working almost entirely. It will start about 25% of the time on the no heat section of the timer, but shuts off almost immediately. It won't turn on at all on either the autosense or timed drying sections of the timer. I have confirmed that the fuse is fine. Do you guys think that the problem is the timer, or is there other stuff that I should check? It's a decently expensive part so I'd hate to replace it in vain. I've pulled a service manual for this thing and have torn it pretty well apart to check things, but I don't have a great starting point for further troubleshooting. Any thoughts or assistance would be much appreciated. Thanks!

Thank you very much for the info and insight. I'll take a look at it and test those wires either tonight or tomorrow night. I do still have it all torn apart, so it shouldn't take long to find out. Thanks again and I'll let you know the results!

First it looks like I did not give you the correct link to the wiring diagram so here it is

[COLOR="Blue"]With the timer in the off position, it read a 1. With the timer kicked on in any of the cycles, it read 0. So, I would assume this is a definite that the timer is fine and not the issue, correct? [/COLOR]
From your description I would say you are correct.

Perhaps this would be the best as your problem seems to be difficult to trouble shoot.

The problem you described where it will only start at certain areas on the timer does point to the timer but it checks out OK.

There is one proviso on this. If you set the timer and then it runs for a while then shuts off and will not start so you start playing with the timer and it starts running. It could be that in this scenario it has nothing to do with the timer.

It could be that the motor is overheating and it's internal thermal protect trips, it then has to cool down before the protect resets. This is when the unit will not start and when it resets and starts it is just a coincidence where the dial is.
