Kenmore won't stop, won't heat

[vic]

The other night, my dryer never stopped running (on timed dry) and didn't heat up. Its a first for both problems...any guesses what could be the cause?

I've seen people suggest Thermal Fuse and Thermal Cut-Off as initial starter spots, followed up with the Heating Element. Any of these that could cause both problems?

Model 110.64722400

I would guess that if both problems started at the same time that they are related.

The first thing I check on any electric dryer that runs, but does not heat is the voltage to the dryer.

A electric dryer needs 240 volts to run the heater, but only 120 volts to run the motor.

If you have a voltmeter check the voltage at the back of the dryer where the power cord connects to the back of the dryer to make sure you have 240 Volts at the dryer.

If the voltage to your dryer is ok next I would check the thermo fuses on the side of the heating element and the element itself.

I do have a voltage meter, but I'm not savvy with it...how do I go about measuring the volts at the back of the dryer? The outlet? Where the cord enters the dryer itself?

[AJ]

I would check it were the cord enters the dryer. There will be three screws on a block that the cord attaches to.

Between the two out side screws you should have 240 volts, between the middle and ether of the two out side screws you should have 120 volts.

Your timer has failed if you have no heat and continuous motor.
The timer not advancing in timed dry is your clue.

What if the one leg of the 240 volt is missing and it's the same leg that provides 120 volts to the timer?

Voltage is good...checked and had 240 on outer screws, 120 on inside. Thanks for the help. Now going to check the fuses.

Re: Timer going bad...should I have heat on auto dry? (I don't, btw).

If your voltage is ok then jumptrout51 is probly correct then, you have a bad timer.

I looked up your model number and it uses timer part # 8299784.

Any way to check the timer with a voltmeter before ordering it?

[whirlpooltech]

You could check to see if you have voltage to the timer motor. If you have 120 volts on the two timer motor wires and the timer does not advance then the timer is bad.

[JWWebster]

Disconnect the power. Remove the fat red wire from the heating element connecting to the timer and clamp a lead of a meter there on the timer. Turn the timer to several different positions and check for continuity to any of the other legs on the timer. If you cannot get a reading from that leg to any other leg on the timer at any setting them the contacts inside the timer are fried. Click on pic to enlarge:

Then the dryer would not start.

Your heating problem could be due to the defective timer.
It could also be due to a bad heat element,limit thermostat or thermal fuse or bad wire.
