Title: kenmore dryer
Post by: goldprospector on February 26, 2013, 01:00:55 PM
If I hold in the start switch with my finger the dryer will run and heat and when I take my finger off the start switch the dryer will stop. And if I push it back in the dryer will run as long as I have my finger on the start switch. I installed a new start switch but it does the same thing. If somebody can help me thank you

Sounds like the motor is bad and needs to be replaced.
What is the model number of the dryer?

That model dryer uses motor part # 279787 (http://click.linksynergy.com/fs-bin/click?id=omv7WULuxaw&subid=0&offerid=225193.1&type=10&tmpid=2111&RD_PARM0=http%253A%252F%252Fwww.appliancepartspros.com%252Fwhirlpool-drive-motor-279787-ap3094233.html&RD_PARM1=http&RD_PARM2=%253A%252F%252Fwww.appliancepartspros&RD_PARM3=.com%252Fwhirlpool-drive-motor-279787-ap3094233.html)

Most likely the switch on the motor is at fault. You could check the switch to see if it's just stuck from lint build up, but most likely the motor needs to be replaced.

You can not get just the switch on the motor as they only come with new motors.

Here is a video that you may find helpful too.

That dryer also has a broken belt switch that is wired into the motor so if the belt is broken the dryer motor will come on start windings only.

You sure about that JW? I can't find the wiring diagram on that model, but I thought models with belt switches would not run at all if the belt was broken.

I can see JW's theory, but will await an explanation to help verify. :D

I thought the belt switch was inline with the thermal overload on the motor.

OOps I missed that one, nope this one does not use a belt switch. The switch might be stuck and can be freed using a little zoomspout oil.

So the cent switch swings open as your hold the start button for a few seconds and holds the run winding keeping the motor running? :D

Two sets of contacts in the motor switch. One set of contacts is for the start winding. One set of contacts is for the heating element.
As the motor starts running the contacts for the start winding opens and the contacts for the heating element closes.

Yeah, the centrifugal switch allows the motor to complete its own circuit so that when you let loose of the start switch the motor will keep running.Since its not doing that it only runs if you hold the start button down.
