I have a kenmore he4 no. 110.85871400. i have no heat replaced thermal fuse high limit thermostat anf thermal cutoff switch. still ni heat. elements are good. cleaned all lint. do i need to get a thermistor allso

If your Kenmore electric dryer has stopped drying, there could be several reasons why:

1. Check the Power Supply: First, make sure the dryer is plugged in and that the circuit breaker hasn't tripped. If you have an electric dryer, make sure the outlet is functioning properly.
2. Check the Thermal Fuse: A blown thermal fuse can cause the dryer to stop heating. The thermal fuse is usually located on the blower housing or at the dryer's heat source. Use a multimeter to check for continuity. If there is no continuity, replace the thermal fuse.
3. Check the Heating Element: A defective heating element can also cause the dryer to stop heating. The heating element is usually located behind the dryer drum. Use a multimeter to check for continuity. If there is no continuity, replace the heating element.
4. Check the High-Limit Thermostat: A faulty high-limit thermostat can cause the dryer to stop heating. The high-limit thermostat is usually located on the heating element housing. Use a multimeter to check for continuity. If there is no continuity, replace the high-limit thermostat.

If the dryer will not turn off, the problem could be a faulty timer or a stuck relay. You may need to have a technician diagnose and repair the issue.

Do all again

Hello
Check high limit thermostat continuity. If ok ,Check for voltage at thermostat side of the heater element.If voltage present timer ok.Most likely centifugal switch at motor.Motor has to be running for element to work.

It's all fixable!

There is a high limit switch (looks like a button with two wires hooked to it) on the bottom of the vent frame. When the vent fills up with lent at the bottom it gets hot. For safety, this limit switch will turn heat off. Remove the vent frame and clean it out and check the continuity of the switch. Also, make sure both heater elements are working properly.

The heating circuit is basically composed of the heating element, thermal cut-off, high-limit thermostat, cycling thermostat, and the motor centrifugal switch. The problem is very likely in the thermal cut-off and the high-limit thermostat located on the blower housing. The thermal cut-off blows when the high-limit thermostat fails and cuts power to the heating element. Both the thermal cut-off and the high-limit thermostat need to be replaced if the former is blown open. Click on the link below for the detailed instructions in troubleshooting this kind of problem.

Both the high limit thermostat #3977767 and the operating thermostat #3387134 are normally closed switches and should have continuity. These thermostats are usually replaced as a set because when one fails its often caused damage to the other. The part # for the kit is 279816 and comes with both and is cheaper than if bought separate

Either your element is out our your thermal cutoff.  Check your element for continuity if it is open, replace the element.  If not check the thermal cutoff which is on top of the element.  If the thermal cutoff is open you will also need to replace the operating thermostat and Hi limit thermostat.  The high limit is on the element below the thermal cutoff, and the opperating thermostat is on the exhaust duct.

have you checked the heat selector switch on the control panal

I eventually changed the thermal cutoff switch and the high limit thermostat as suggested in one of your replies to another consumer and now the dryer is working fine. Thanks.

the thermal cut off wires do not matter how you put them on.. The high limit is wired in series with the heating element.one red thick wire to element the wh/red top side of the high limit stat out of the high limit sat(other side) then goes to the other side of the heating element
