You have remove the fuser unit. The inner cover needs to be removed for this so you can disconnect the fuser unit.

If the thermistor needs cleaning more than likely its failed any way.

Inlet thermistor open f24


A thermistor changes in resistance with changes in temperatures. As the air is drawn out the dryer into the blower and discharged out the machine, the resistance changes made by heat differential is monitored by the control. If the control cannot get a reading from the thermistor it does not know what the temp is inside the dryer so it declares an error and shuts down. You must not only replace the thermistor you gotta clean up the innards to do the job right. Their are videos on yourtube which show how to replace a thermistor in a dryer.

I have model # GEW9250PW duet front loader dryer and keep getting a code E1


This is a failed thermistior error code.

The machine control electronics monitors the

exhaust temperature using the thermistor, and

cycles the heater relay on and off to maintain

the desired temperature.

Begin with an empty dryer and a clean lint

screen.

1. Plug in dryer or reconnect power.

2. Set the following configuration:

? Door - must be firmly closed

? Press Control On

? Press End Of Cycle Signal (Louder)

? Press Start

3. If after 60 seconds, E1 or E2 flashes in the

display and the dryer shuts off, the thermistor

or wire harness is either shorted or open.

? Unplug dryer or disconnect power.

? Check wire connections at the machine

control electronics and thermistor. See

Accessing & Removing the Electronic

Assemblies, page 7, and figure 8 for

thermistor location.

? If wire connections are good, remove the

two wires from the thermistor and replace
the thermistor.
the part number is 8577274 you can remove the lower panel in the front to change the part.
thanks and please rate me thank you....ken

Error code E01 on my electronic dryer


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.

The dryer will not operate if the exhaust temperature drops below 18 degrees F. or exceeds 250 degrees F.

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 available from the following: www.searspartsdirect.com

Enter your model # in the appropriate box to get a full parts break-down and diagrams.

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.



When the thermistor circuit is open (>50K ohms), the error code E1 flashes in the display.

When the thermistor circuit is shorted (

Normal thermistor resistance values:
60 degrees F. - 15.3K ohms.
70 degrees F. - 11.9K ohms.
80 degrees F. - 9.2K ohms.

The thermistor -may- check ok when cool and freak out when warm!

Kenmore elite, model 110 60952990,stopped working after I tried to dry a pair of sneekers. It doesn't do anything when the power butten is pushed. Thank you.


The thermal fuse (part number 3390719) is blown causing the motor not to run. This thermal fuse is located on the blower housing beside the thermistor (part number 8577274) and it is wired in series with the motor thereby cutting power to the motor when it fails. The failure of the thermal fuse is due the failed thermistor; these requires both the thermal fuse and the thermistor to be replace.

Access to the thermal fuse and the thermistor for replacement or testing requires the removal of the lower front access panel which is secured to the front panel by two retaining clips positioned about three inches away from the sides. Pry the clips to release it and remove the lower front access panel. The thermal fuse and the thermistor can now be accessed.

Using a volt-ohmmeter, check the continuity of the thermal fuse which is to the left of the thermistor. Replace the thermal fuse if it reads open together with the thermistor.

Remove the mounting screws and mount the new parts in place. Disconnect the wires from the old failed parts and connect it to the corresponding component. Reinstall the lower front access panel back into position.

It starts working for a minute and it stop working


It is an indication of a shorted thermistor. Disconnect power to the dryer and check the resistance of the thermistor.

The thermistor (part #8577274) is located on the blower housing with red/white stripe and black wires and can be accessed by removing the lower front access panel. Remove the two hex-head screws attaching the bottom of the lower front access panel to the cabinet and pull the bottom out then down and move the panel away from the cabinet.

Disconnect one wire from the thermistor and use an ohmmeter, set to X1, to measure the resistance. Touch the ohmmeter test leads to the thermistor terminals and measure the resistance. The resistance reading at room temperature of a good thermistor is between 8.5 and 13.5 ohms; otherwise, replace the thermistor.

Remove the two screws mounting the thermistor to the blower housing then mount and secure the new thermistor in place. Connect the thermistor wires then slide the lower front access panel up back into position to the cabinet and secure its bottom with the two securing screws.

In case the measured thermistor resistance falls within the allowed range, measure the resistance between the disconnected thermistor wire and the other one. Replace the dryer control electronics (part #8546219).

Remove the screws attaching the top panel to the rear of the dryer then slide the panel rearward and lift it off.

Facing the front of the dryer, the dryer control board is located on the left mounted behind the bracket. Remove the three screws holding the bracket in place then rotate assembly up and set it on the side panel.

Disconnect the wiring harnesses from the control board one at a time then connect it to the new control board.

Remove the control board mounting screw near the transformer then press the side ends one at a time to release the mounting tabs and lift the end away from the bracket.

Secure the new control board to the bracket and reassemble the rest in reverse of the steps given above.

DLG5932 gas dryer blows its overheat fuse, after reset by technician it heated fine. On the first load of laundry it heated for a while, and then blew out the overheat fuse again. Dryer was totally cleaned...


The dryer is overheating but is not the fault of the vent. Have the technician check the operating thermistor on the exhaust behind the blower wheel. This thermistor acts as the thermostat for this dryer and if it is off will either not allow the dryer to heat or will overheat the dryer like in your case and cause the thermal fuse to blow out or trip. He should measure ohms and according to temperature and should have access to what it should measure. If the thermistor measures bad, replace thermistor. If this measures good the control board is reading the thermistor wrong and the board will need to be replaced.
Thank you
