This part is the replacement high-limit thermostat, or simply the thermostat for your dryer. It is approximately 2 inches wide from tip to tip. The center, rectangular portion of the thermostat is approximately 1 inch in width and a little more than 1 inch in length. The thermostat is a safety device that regulates the temperature inside the dryer. If the thermostat is shorted out, your dryer may not be getting any heat, and you will need to replace it. You can test the high limit thermostat for continuity by removing it and connecting it to a multimeter. Be sure to disconnect your dryer from the power source before you begin this repair. This is an OEM part sourced directly from the manufacturer.

Sorry, we couldn't find any existing installation instruction that matched.
No heat; flow-sense error diagnosed but no blockage in exhaust.
The first thing I did was locate a copy of the Service Manual (not the User / Owner Manual). After looking at that and looking online I learned that there is no sensor for the Flow Sense feature itself. The Flow Sense doesn't detect a blockage. It detects excessive heat and the manufacturer has simply concluded that too much heat is most
... Read morelikely caused by a blocked duct and then it activates the Flow Sense safety feature: cutting off the heat source. Since I knew it was a heat problem I figured I'd get inside and check the two thermostats and the igniter. Igniter was fine, one thermostat was fine, the other one - the High Limit Thermostat - was giving inconsistent readings. I replaced it. Here's how: First I took the dryer apart. This is a little time consuming. There are a lot of parts that need to come out. I recommend that you put the screws in small baggies with a note as to where you took them out of so that you know where they go when you put it back together. You need to remove part of the back, the top and the front. I removed the electrical box because that is what is shown in the manual but I'm not convinced that I needed to. See if you can get the rest of the dryer apart without removing it but if you have to remove it it's not that big of a deal. It's a little tricky to detach the wire harnesses is all. And extra steps, of course. I did not remove the drum. Instead I just reached inside with the front off and pulled the wires off the thermostats to test them for resistance with a multimeter. It was kind of a pain and a little awkward but I did not want to mess with the drum tensioner. Once I figured out that the High Limit Thermostat was the likely culprit I removed it - which required a very short Phillips head screw driver and some patience since I could not actually see one of the screws. But all good. Just remember which wire goes on which terminal. Make a note for yourself: gray back / red front - something like that. Then I ordered the part and installed the new one and rebuilt the dryer in reverse from what I did.
Now, here's the thing: I actually did two things: aside from changing the thermostat I also thoroughly cleaned out the dryer. Somehow a lot of lint built up in there - no idea how since it all appeared to leave the dryer through the vent. but there must be some small gap somewhere. I cleaned everything including the flame detector. When I put it all back together it worked but I'm not 100% sure that the thermostat was bad. It's at least possible that all the lint and dirt was messing with the way the thermostats behaved. So what I would recommend, if you have this problem, is to clean it out first and then put it back together enough to run it and see of the heat comes on. It will take maybe 30-60 seconds for the heat to come on while the igniter lights. If not, go ahead and replace whichever thermostats or other parts you think are broken.

Dryer takes too long to dry cloths, the blower duct and vent are clean
For model number DLG4871W
Hi George, thank you for your question. Looking at your model information there are a few parts that you should take out and test to see which one is giving you the issue. The first parts to check in this case would be all of your thermostats and thermal fuses. You can test those parts with a multi meter and they should be reading 0 ohms to be working correctly. If those parts are fine, you should then go on to testing your heating element as well. You can also test that with a multi meter and it should be reading between 0 - 50 ohms. 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. I hope that helps. Good luck with your repair.

Starts but shuts off
For model number DLG5002W
Hi Lorenzo,
Thank you for your inquiry. The most common parts that will fix this issue are the sensor, the thermostat and the thermistor. To verify which part is causing the issue you will need to use a multimeter to check the continuity on them. I hope this helps. Thank you and have a great day!

How is the igniter replaced. Do you have to remove the front panel and how is it done
For model number DLGX5171V
Hello Robert thank you for writing .
Normally you would remove the top panel which should have 3 philips screws on the back. Once you lift the panel up the ignitor is exposed for replacement. Hope this helps. Contact us anytime.

High limit reset keeps getting tripped and i have to keep clicking the reset button. I do think the dryer is getting too hot, there is some plastic melted to the back of the drier. Any idea of what part/parts i should be replacing?
For model number dlg0452w
Hello and thank you for writing.
It certainly sounds like it could be a faulty temperature sensor PS3529161 and/or possibly a malfunctioning thermostat PS3529026you should check the part(s) for signs of damage or test with a multimeter, and replace the part(s) as needed. We hope this helps. Please contact us anytime if you require further assistance.
I am getting a d90 error code I have clean flow through my dryer and duct what else could be causing this?
For model number DLG4971W LG
Hello Harold, thank you for asking! D90 error indicates a blockage in the ventilation system. Before moving towards other parts, please make sure that you have checked the lint filter and make sure it is not blocked or damaged. We hope this helps. Thank you.

My dryer doesn’t heat until i reset the high limit switch, i then run it for a few minutes and it trips again for which i to reset it once again….What part is failing?
For model number DLGX5171W
Hello Martin, Thank you for contacting us. We have researched the model you have provided and have found
the parts you are looking for may be the Dryer Thermistor PartSelect Number PS3529026 and Thermostat PartSelect Number PS3530484. 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.
