This dryer thermistor temperature sensor helps monitor and regulate the temperature inside a dryer. This part includes the wire harness. If your dryer overheats, does not produce enough heat, or takes too long to dry, then the thermistor might be defective or damaged. This can cause a fault code and could begin either prolonging or shortening drying time. As a safety precaution, make sure to unplug the dryer from the power source before beginning this installation, and wear gloves to protect your hands. Refer to the installation instructions provided by the manufacturer for further guidance.

Hello, my previous question was not answered. I guess i should have noted that I’m an electrician and test components every day. I do not need a video showing how to test for continuity. I need to know if all three thermal fuses are normally closed? My thermistor is reading 13.6k ohms at room temperature and the thermostat is closed (0.0 ohms). The high temp thermostat cut out fuse is blown and I know I need to replace it, I’m only trying to determine if the thermostat or the thermistor are bad as well causing the poor heat supply prior to the blown fuse. Should the thermostat have any resistance at room temperature or is it merely and on/off switch? And what should the thermisters resistance be at room temperature? Thank you for your help!
For model number DLE0442W
Hi Denette, Thank you for contacting us back. The high limit thermostat on this unit would open at 257 degrees and close at 221, So at room temperature it should be closed.For the Thermistor 10K ohms at room temperature at 70 degrees the resistance should be 9.3K ohms, 90 degrees would be 7.7K ohms, 100 degrees should be be 6.2K ohms, 120 degrees 4.3K ohms. The Second thermostat fuse should read closed or 5 ohms or less at room temperature. Hope this helps!

Will this make your dryer not power on?
For model number DLE2301R
Hello Billie,
Thanks for your question. If your dryer is not powering up, you may want to test the motor, along with the thermal fuse and the belt. Test the electrical components with a multimeter to check for continuity, and replace any part that does not show continuity.
I hope this helps.
What should the resistance be at 70 degrees on the thermistor? Should the high temp cut out (thermostat) be open at room temperature (part # f130)? I’m trying to determine what component is bad? I have had poor heat for awhile and now no heat at all. I pulled it all apart and had a lot of lint on the heating element and the rear thermal cut out (f140) is closed while the f130 part number is open. Is it blown?
For model number DLE0442W
Hello, Thank you for your inquiry. I have included a link to a video on how to test the thermal fuse and thermostat with a multimeter. Hope this helps!

We have an LG gas dryer, i had a technician come and look at it today because it won't heat up. He told me that it was the control panel and they no longer manufacture it so the dryer was unfixable. Could it possibly be something else? It still tumbles and gets slightly warm.
For model number DLG7188RM
Hi Noreen, thank you for your question. When you are experiencing an issue like this there are a few parts that you will have to test to determine what is causing your issue. For all of these parts you can test them with a multi meter. First you will have to test your thermostats and thermal fuses to make sure they are all functioning correctly. After that you will want to test parts in this order, your m series coils, igniter itself, or your radiant flame sensor. You may also want to check your regulator just to make sure that part is functioning properly as well. I hope that helps. Good luck with your repair.

I have a stackable natural gas LG dryer that is not drying the clothes. The lint filter and flexible exhaust hose is clean as well as the exhaust pipe to the roof. An authorized technician replaced the igniter and it is still not drying the clothes. Yes, the gas valve is turned on and there are no blown electrical breakers. What is the real problem?
For model number DLG2526W
Hello Dennis,
Thanks for your question. There are a few different parts you will want to have tested with a multimeter to ensure they have continuity. Replace any that do not have continuity. Test the thermistor, thermostats, the flame sensor, and the temperature sensor.
I hope this helps.
Hello i just change my dryer from lp propane to natural gas and it was working fine before the change. Now it turns on and off and does this over and over. I can see the igniter glow and the gas fire up but shuts off in seconds and cycle over and over. I did test lots of the sensors for continuity and everything i check was good. I also back out the nut on the gas regulator like it said in the instructions when i change the lp propane to natural gas orifice. What else can i do or am i missing to check? It's also free of lint.
For model number DLG2302R
Hello Alberto, thank you for inquiring. For this symptom you will want to replace either the Sensor part PS3529161, the Thermistor part PS3529026, or the Blower Thermostat part PS8747887. We hope this helps.

My dryer turns on won’t fire up gas i do see orange glow from igniter however no ignition or gas smell either every ten to twenty seconds it would glow orange by burner tube but not light everything works no codes otherwise i pulled it apart to check for lint etc and reset button however button didn’t click or do anything so that wasn’t it but the front face by lint trap was over half full of lint i did notice other than that not sure what it could be possibly gas balance or thermal fuse but continuity was weird my multimeter was reading real high then going towards zero and past zero to negative on the thermal fuse and the reset button thingy i really don’t know if i’m using the multimeter right it’s weird also when i turn the dial to continuity or resistance it beeps at me right away without touching anything i think it’s broke too help please thanks

Hi Guy. thank you for your question. When you are experiencing an issue like this there are a few parts that you will have to test to determine what is causing your issue.

You may also want to check your regulator just to make sure that part is functioning properly as well. Something else you should also check would be your filter and ducts. Make sure there is absolutely no blockage that would restrict air flow in your appliance. We have a video here that will show you how to use a multimeter: https://www.youtube.com/watch?v=bWC44fHn0As. I hope that helps. Good luck with your repair.

My cotton/normal and permanent press cycles are not working properly, the clothes have to be turned on again to get dried. I thought it was the element going out. But now I wonder if it is the thermistors. How would we test them to make sure?
For model number DLEX3370W
Hi Janette,
Thank you for your question. Using a multimeter on the Rx1 setting, touch the probes to the terminals. If you receive a reading of anything other than zero, you need a replacement temperature sensor/thermistor. If you have any questions, please let us know. We look forward to hearing from you!
