SOURCE: 8577274 for Whirlpool Dryer Thermal

Hi ibw3rd
To answer your question...No the dryer will not run if the Thermal/Thermistor/Fuse is faulty.
Here are a few more things to check also
Please take time to rate me
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 the dryer,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 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 not 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.
If the coil heats up then replace the thermostat/thermistor/thermal fuse as it is faulty.
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.
To test your thermostat/thermistor/thermal fuse remove the wires from the thermostat/thermistor/thermal fuse and check for continuity, if you DO NOT have continuity then replace the thermostat/thermistor/thermal fuse.
Check your blower wheel to make sure it is secure to the shaft and not plugged with lint,socks,etc.
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.
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.

What does the E1 error mean?

E1 means: Thermistor Failure. You will need to replace this.

Here's the thermistor for your model you can order:
Thermistor 8577274
You would need to take off the lower front access panel under your door, then take off the duct assembly#45, by removing the two #32 screws, and remove the #2 screw at the very bottom of the duct assembly with a bracket#11 attached to it, remove that one also. Unplug your dryer first! Then your thermistor is #42 on the blower housing, next to your thermal fuse#59.

I have a Whirlpool Cabrio dryer, model WED6400SW, that displays an F23 code. What type of problem does the F23 code signify?

Your heating circuit is out of range. Most of the time, it's the thermistor that has gone bad.

Sears has the replacement:

Thermistor 8577274

If that doesn't do it, then the next most common culprit is the main PCB board.

My He3 dryer has a message E1 and will not dry the clothes

E1 is usually a bad Thermistor. Here's the one for your model you can order: Manufacturer Part # 8577274

You would need to take off the lower front access panel under your door, then take off the duct assembly # 45, by removing the two # 32 screws, and remove the # 2 screw at the very bottom of the duct assembly with a bracket# 11 attached to it, remove that one also. Then your thermistor is # 42 on the blower housing, next to your thermal fuse # 59.


Hope helps.

Kenmore elite evenflow with auto temp control starts drying and after a couple of minutes gets an E1 error code. Does not appear to over heat and is not on long when it errors. Does it on all settings.

E1 code indicates a thermistor failure. You will need to replace the thermistor. Remove the lower panel to access the thermistor. It looks like the picture below...

Kenmore HE3 Gas Dryer F23 error

Hi there,

Well the F23 error code is an exhaust thermistor error. It indicates the thermistor is shorting out. This occurs after the thermistor heats up and that is why it happens after 2 minutes. Remember to unplug the power cord so there is no voltage present while servicing. 

All you need to do is to pull the dryer out from the wall and be able to get to the back. If you can do this then you can replace the thermistor.
you can check out the below link for more information -,wksdqrtgsdbddsdxgtqsskgwtqkq,vi/wbrfdqtbtxwkrtsktgt/1/1303472/5961857/image59719img-or.gif

The thermistor part number is 8577274.

Good Luck!!

HE3t kenmore dryer E1 error - have replaced the thermistor and checked the airflow out of the house and it still kicks the E1 error. The only time that it doesnt is when the dryer is on air dry

The E1 displayed indicates the thermistor is open and needs to be replaced.

The connections can be loose but the most likely cause of an E1 error is a bad thermistor.

If you're comfortable and confident in your do-it-yourself skills and have access to a volt/ohm meter you can check and replace this part yourself.

The thermistor is part number 8577274 and is available from the following

To access the thermistor see the image below. Remember to unplug the dryer from power first.
The thermistor will have a black and red/white wire on it.
You can check continuity across it with the meter and if the circuit is open then the thermistor needs to be replaced.,wkrsfrgsskrbttbxgtqsskgwtqkq,vi/wbsdwtgwgxwrgbbgsgs/1/1303472/5961857/image6767img-or.gif

My GEW9200LW0 electric dryer will stop after a few minutes and flash E1 code. Is it most likely a faulty thermistor? How do I know the correct part # to order?

HI, the thermistor is the culprit in this situation. the actual location of the affected part is inside the unit, on the blower housing(mounted on the backside). The part number is (3976615)

E-1:=(Failed Thermistor)

SIDE NOTE:-The manufacturer has replaced part number 3976615 with this item, part number 8577274. 8577274 may differ in appearance, but is a functional equivalent to prior parts including 3976615.
