Model # 110 70712990. Dryer continues to run through all the timer cycles. I set timer for 20 minuets, timer advances and dries clothes, timer advances to off, dryer turns off, timer continues to advance through off position, timer advances and the dryer turns back on, runs through next cycle, turns off, timer advances again, dryer turns back on. The dryer stops when the door is opened or the dryer is unplugged.
Any help
thanks

Well, it should not do that.

Sounds like a bad timer, here is the part.

Part number: AP3100523

Good luck,

Thanks for the reply.
How can I test the timer to be sure it’s bad before I pony-up the $90.00?

Unfortunately there is no good way to do that, you sorta arrive at the timer by a process of elimination, in this case there is not another likely candidate.

If your timer is doing this in all cycles it is highly likely the timer is the problem, but the only way to be certain is to replace it and see if that cures the problem.

[Jimmy-bow]

Okay I’ll just replace the timer. The part number on the timer is PN: 3976577 which matches the one called out at Sears Parts Direct. Com. But your attached PN is different. Should I care? And do you get compensated if I order form Appliance Parts Pros?

Hi Jim

The part number shown in the picture is an Appliance Parts Pro part number, but the part should be the same. You can confirm this by going to the Find Parts section of this Forum and checking the part by the number from SearsParts and the part shown in the picture will come up.

We are volunteers and do not get compensated in any way by the APP company. They put up the web site to help folks (and I imagine to also generate some business) and we (or at least I) volunteer to answer questions for the challenge of trying diagnose a problem wihtout actually seeing the machine in operation. Plus it also hones diagnostic skills for repairing appliances. It sorta allows us to have the fun of fixing the machine (diagnosing) without having to get all dirty and twisted by having to do the actual work.

So, we can also say go where the part is the least expensive, which in your case looks lik Sears, but check whether or not there is sales tax in your case and also the shipping charges to get a full comparison. One thing you will find from APP is that delivery is very, very fast.

Good luck, let us know if a new timer fixes things.

Wow that’s nice of you to help. I’ll order the timer and let you know if it resolves the problem.
Thanks again

The new timer didn’t fix the problem. The timer continues to advance until the dryer turns off and then back on again.

I am both somewhat amazed and completely apologetic. Unforturnately using a Forum like this for repair involves what economists term tradeoffs. If you have a service tech visit, you will get your machine repaired, but at a cost of $150.00 to $250.00 in your situation. If you get a recommendation from a Forum you will spend a lot less, but there is not a guarantee your machine will get repaired. We may not have the correct diagnosis, you may not put the part in correctly, or the replacement part may be defective.

In this case I don't think you put the part in incorrectly, and I doubt if the replacement part was defective. That leaves us with an incorrect diagnosis for which I apologize and I am sorry you spent the funds unnecessarily.

That being said, we still have your dryer to fix. I am thinking you may have two problems, a short in the wiring to the timer motor and a bad push to start switch. The way your dryer timer works is that there is a small motor in the timer that is powered by electricity. When you engage the timer the motor powers up and turns the timer gears which go through various sets of electrical contacts and operate your dryer according to plan. When the dryer gets to the off position, the circuit is broken and electricity no longer goes to the timer motor and the timer stops advancing.

Obviously in your case the timer motor in the timer is continuing to get electricity even after the dryer reaches the off position. This suggests that the problem is in the wiring to the timer motor, but that wiring comes through the timer, which is why the first thoughts are that the timer was bad. Well,unless the second timer is bad you somehow have power getting to the timer motor independent of the timer, and you are just going to have to trace that wiring to find out how that is happening.

Now the second problem is that after your timer advances to the next cycle the dryer comes on. This definitely should not happen, because even if the timer advances to a start position, the dryer will not come on unless the push to start switch is pushed, which is not happening. Now the way your push to start switch works is kinda interesting. When you engage the push to start switch, electrical current working through a coil inside the switch keeps it closed even after your release the start knob and it returns to its rest position. When current stops going to the start switch, the electricity through the coil stops and a spring makes the switch disengage. This is why your dryer stops when the timer gets to the off position.

Now obviously the push to start switch is remaining engaged, so that when the timer gets to the new cycle the dryer turns on. This suggests either a bad push to start switch, or problems in the wiring between the varous components and the push to start switch.

Therefore I suggest you replace the push to start switch, as it is an inexpensive item and replacing it will take it out of the equation. If that fixes the problem, great, if not you are going to have to trouble shoot your wiring starting from when it comes into the dryer from the outlet.

Well, I hope this helps, and I wanted to explain what is going on as much as possible so you would understand why the timer was suggested and the rationale for the next steps.

Good luck, let us know what you find out.

[Jimmy-bow]

Yeah what I disappointment… I thought I was going to be the hero last night, but I was still just a zero.
I’ll get the switch tonight, and write you back when I’m done crying.
