Kenmore Dryer Won't Stay On

Kenmore Elite Dryer, model 101 63942101.
Tried to run the dryer through the usual cycle. But it will now only run when I hold down the start button. If I release the button the dryer stops.
Any ideas on what the issue might be? Thank you.

Have you checked for 240 VAC at the receptacle ?

There is a switch that closes once the motor starts spinning. That switch would normally be open and when you push the start button you short it out until the centrifugal switch on the motor takes over.

I don't have the wiring diagram for that unit but I don't think it uses any relays for the motor.

After checking for 240 VAC and confirming it..... I would check the wiring on the motor. Unplug the dryer before checking the wiring. You are looking for a loose contact or plug.

The dryer will blow hot air as long as I am holding the start button down.
I popped open the control panel and this is what I'm looking at. The start button is the furthest on the right. I am a complete know-nothing about these things. Do the pictures reveal anything?

Ok...if it blows hot air then you do have 240 volts present.

There will be a schematic.... most likely on the rear access panel. Can you shoot me a pic of it. It needs to be as large as possible. You may have to email it to me as the board will only allow pictures of a certain size.

Nohing amiss in your pictures. Still pretty sure the problem is the centrifugal switch on the motor or in the plug there.

PJ, I'm running a cycle right now since I had some wet clothes in the dryer. I placed a small weight against the start button for the time being and it's working fine. No danger in doing this, is there?
I'll see if the schematic is available and will email you a copy. Thank you.

I sent my email address to you in a PM.

The idea is that if there is a problem with the motor..... like something jamming the drum or something stuck in the fan and it stops turning.....the power is automatically disconnected.

Received the PM. Thank you.
Just completed a cycle and clothes dried normally. The weight against the start button is a temp, but efficient fix.
Am I being hopelessly optimistic in thinking that the start switch, the one on the far right with the two black wires coming out of it in the picture above, went bad and only needs to be replaced?

The start switch is a normally open momentary switch. That means just sitting there and doing nothing it will be open. When you push the button it will short.... which it does....then it will return open when you let it go. There is a set of contacts in the motor that take over that switch once the motor gets up to speed.

It's like having two identical switches connected together. The top switch you push to activate and the motor one that the motor keeps pushed in once it starts turning.

Real common problem with your dryer, Either the control board or the run relay. Look at the board toward the bottom and see if you see a burnt resistor on it. (use to be very common but not so now) the other thing is the run relay, in your picture the one with pink and blue wires. I have found this is most common to go bad.

pugsl, thanks for that info. So it is possibly the relay next to the start button relay? Interesting. I may try replacing that first and hope it solves the problem. $50 at Sears. Wow.
Just did a search and found it for $9, (plus $5 shipping) on Amazon: Whirlpool 3405281 Relay for Dryer - Amazon.com

That would be the relay. Some of Sears parts prices are outdated.

To update, ordered a replacement run relay from Seneca River Trading. $9 plus $5 shipping. Replaced the old one and, sure enough, that was the problem and the fix.
Many thanks, gents!
