I HAVE A HE3 DRYER HAD TO REPLACE THE THERMAL FUSE AND THE THERMISTOR, DRYER STARTED FINE DRYED ONE LOAD AND BACK TO NOT STARTING THE CLOTHES SEEMED HOT WHAT WOULD CAUSE THESE TWO FUSES TO GO. THE AIR WAY IS CLEAR.

Question edited for spelling 'Lent' to 'Lint'.

The auto dry feature uses a humidistat to sense the amount of moisture in the air as it is exiting the dryer.

The thermistor / thermostat is a heat sensing device and that is the one to change first. If inaccurate it cuts the heat off to soon resulting in a warm heat drying cycle instead of HOT.

There are two other devices, a thermal fuse which will cut power when the dryer over heats and it doesn't sound like yours is. Finally there is a Thermal Cut Out, and when it overheats so badly the fuse breaks and has to be renewed.

The other thing to check is the the vent outside is clear of lint and that the flap or grille vents are opening fully when the dryer is running..

Good videos, and the second video shows testing components.

Thermal fuse may be blown.

Hi sandygann
Here are a few things to check:
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or inside of the dryer venting system,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the heating element/thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if you do not read continuity you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor/thermal fuse one at a time by removing the two wires and taping them together with electrical tape.
Try to run the dryer, if it runs and heats up then replace the thermal fuse/thermistor/thermostat.
If you have an ohm meter then you can test the thermostat/thermistor/thermal fuse,then you do not have to tape the wires together as described above.
But do not trust the ohm meter all the time, because sometimes it will give a false positive that the fuse is ok when in reality it is faulty.
DO THE FOLLOWING TEST:
To test your thermostat/thermistor/thermal fuse remove the wires from the thermostat/thermistor/thermal fuse and check the fuse/thermostat,thermistor for continuity, if you DO NOT have continuity then replace the thermostat/thermistor/thermal fuse.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST AS THIS COULD CAUSE A FIRE BECAUSE YOU HAVE REMOVED THE SAFETY.
This test of the thermal fuses,thermistor,thermostat, will show if the thermal fuse,thermostat,thermister is really faulty or not.
Check your blower wheel to make sure it is secure to the shaft and not plugged with lint,socks,etc. If you have to replace your blower wheel it will remove clockwise as looking at the blower wheel. You will have to hold the belt end of the motor with a vise grip pliers or maybe the shaft of the motor has a notch cut on it for a wrench to fit.
If the thermal fuse overheats the dryer will not operate. It's located on the blower housing. It cannot be reset.
You can test it with an Ohm meter or continuity checker, remove both wires from the thermal fuse and put the test probes to each of the ends of the thermal fuse, if no continuity then replace the thermal fuse.
If you do not have a volt/ohm meter then:
DO THE FOLLOWING: Remove the wires and tape them together and try to start the dryer.If the dryer starts then replace the fuse.
A vent clogged with lint can cause it to overheat.
Right after replacing a dryer element, always run the dryer on air fluff/no heat, and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

This problem is commonly caused by a blown thermal fuse located on the blower housing behind the bottom panel. Remove the bottom panel then the lint duct and check continuity of the thermal fuse. You can also bypass the thermal fuse for troubleshooting purposes. Check for blocked lint filter and restricted vent system if the thermal fuse is indeed blown then replace it including the thermistor.

Kenmore Elite and Whirlpool Duet Dryers Not Starting

you need chek :
if your apliance is gas dryer:
1-thermal fuse.
2-sensor flame.
3-ignitor.
4-gas valve.

if is electric dryer:
1-thermal fuse.
2-heater element.

Hi, how are ya?

The E1 is a thermistor problem. It's a little black fuse that's next to the thermal fuse on the duct housing.

It's pretty easy to fix. You need to take the bottom pannel off and then the black blower housing.

Good luck :)

Q - My gas dryer will not heat, what could stop my dryer from heating?
A - Things that could stop a gas dryer from heating:
- glow bar igniter, thermal fuse ( not all models ), coils on the gas valve, gas valve, thermostats,motor heat switch, timer, selector switch, sensor.
A page for checking gas dryers is here.

repl/ thermal fuse if no heat if heating for a little while clean exhaust, and repl/ coils

Thermal fuse on the blower housing is open. Take back off and the thermal fuse is near the blower outlet. It is white and about 2 inches long. Part number is 3392519
