The thermostat is a part for your dryer, and it is roughly 1 inch long by roughly 1.5 inches wide. The purpose of the thermostat is to measure the temperature of the air inside your dryer drum. As the air is being measured, it will turn the heat on or off in order to maintain a stable temperature within the drum. The most common reason you would need to replace your thermostat is if your dryer is not receiving enough heat, or any heat at all.The tools you will need to complete this repair include a Phillips screwdriver, and a flat-head screwdriver.

Dryer will run, but not heat, stays on cooling cycle. Can you suggest the correct part?
For model number DLEX5101V
Hi Michelle,
Thank you for your question. I could suggest you check your heating element, your thermostats, and thermal fuses. Make sure those parts are still working. You can test them with a multi meter. Check and make sure your vents and filter are free of lint. If all of those parts are fine, it may actually be your control board that is the issue. I hope that helps. Good luck with your repair.

Dryer drum tumble/turns but doesn't heat up at all after basement got flooded. The only parts that i haven't replaced yet are the motor and the blower thermostat. I've replaced the main board, heating element with all fuse, thermistor. I tested the blower thermostat and there is continuity. I vacuumed it to remove lint. Are there anything else that would stop it from heating? Is it possible for the blower thermostat to show continuity but still bad?
For model number DLE4970W
Hello Rockko, thank you for your question. Chances are the motor itself needs to be replaced. If the thermostat is showing continuity it has not failed. I hope this helps!

I am looking to test the thermostats with an ohm meter. Can you tell me their resistance in relationship to their temperature? Ps3529026, ps3530484, ps3530486, ps8747887
For model number DLG2526W
Hello Chip,
Thank you for your question. At 70 degrees the resistance should be 9.3K ohms, 90 degrees would be 7.7K ohms. at 100 degrees would be 6.2K ohms, and 120 degrees would be 4.3K ohms. If the thermistor reads outside of range then it needs replaced.
I hope this helps!

Dryer will not heat up. Drum turns. Is it more likely to be thermostat or igniter?
For model number DLGX8388NM
Hi Jerry, Thank you for the question. I suggest replacing the igniter.The thermostat would need to be replaced if the dryer was over heating or not getting hot enough. Hope this helps!

Our dryer won't stop tumbling after the cycle is over. It stops when you open the door, then starts back up when you close it. Sounds like a bad cool-down sensor. Which thermostat/thermistor would be bad on this model? I found 3 on the parts list.
For model number 79691373210
Hi Scott,
Thank you for your question. If the dryer is not shutting off, then you will need to check the door switch, the electronic control board and the thermostats. I hope this helps. Thank you and have a great day!

I have two blower thermostats on n my lg dryer
For model number DLG305lw
Hello Debra, thank you for your question. Your dryer has two thermostats. The High limit thermostat, part number PS3530484 and the Blower Thermostat, part number PS8747887. We hope this helps.
My LG dryer will not start at all. When I press start just hear a click and nothing else. Just replaced thermal fuse, no progress at all. Should I change the thermostat as well?
For model number DLEX568OW
Hello Vanisa, Thank you for your inquiry. If your dryer will not start and instead makes a clicking noise, it is most likely due to a fault with the door switch, start switch, or thermal fuse. Since you have already replaced the thermal fuse, we would recommend the door switch next. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, we have videos available to assist you. We hope this helps and if you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!
Which part(s) sense the exhaust duct flow and trigger Flow Sense bars and D90 failure? Just had duct work cleaned from dryer to outside and still get failures. Now suspect sensing fails.
For model number DLEX4070W
Hello James, We also suggest cleaning out the Duct in the dryer lint filter area and the dryer cabinet. Make sure the Hose to vent the dryer as no dips. If everything is clear, we suggest testing the Thermistor and the thermostats with a multimeter. If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!

Dryer not heating
I followed video instruction in disassembling and set screws from each section into diferent small bowls in the order they were removed. Hardest part was some of the screws were really hard to get loose without stripping them and my control panel did not match video but I figured it out. Replacing the parts were easy and putting it back together. While it was apart I cleaned everything including fan blower wheel. Thanks for the right parts and your online video. With your help and a prayer this 62 year old woman fixed the problem and dryer runs like new.
I'm not for reading instructions. So I just dove right in and took the dryer apart to get down to the motor. I gave the dryer a thorough cleaning and replaced the 3 parts I ordered from the online recommendation. Wish I would have ordered 2 sensors and the 2 thermostats that are near the burner. Just so replace beings I was in there. Replacing the parts was easy, found them just by looking for matches to the new parts. Reassembled the dryer, dont think I put a single screw back where I got it lol. And still haven't put the top lid back on due to difficulty. Not sure if I even needed any parts, found a nest in my outside vent completely plugging it. But after a good cleaning and replacing the parts the dryer dries the best it has since we've owned it. The dryer came with our house which we bought 3 years ago and it was 2 years old when we purchased the house, so it is now 5 years old.

Faulty part, no good.
The thermostat that was mailed to us was faulty. When replaced there was still no heat to the dryer and when the Tech checked it there was no activity on the conductor/tester so we ended up not using it at all and not worth returning as the part only cost $12.50 and then we again would have to pay for shipping so it wasn’t cost effective to return. We ended up bypassing the wires because as the thermostat shares another thermostat on the same line/connectors.
