This thermal fuse acts as a high-limit thermostat, and shuts off the heating element when the dryer overheats by cutting off power to the dryer. If the thermal fuse has blown, the dryer will not start. These fuses cannot be reset, so if yours has blown, you will need to replace it. A common reason for the thermal fuse to blow on a dryer is if the exhaust vent on your dryer is restricted or blocked. Hot air will be confined in the dryer and the fuse will trip and stop the electricity from flowing to the gas valve or heating element.

Heater wouldn't get hot - suspected thermal fuse

Added air diverter on exhaust hose and blew out heat limiter fuse.
Entered dryer from rear exhaust port. Removed 2 screws and 2 clip on wires. A little awkward of process but superior method over disassembly of drum and main parts.

The dryer worked fine except the dryer did not heat up
I unplugged the dryer and disconnected the vent. I pulled the dryer away from the wall so I had room to work on it. Pulled the top cover off (slides back). Took the door off Took the front adjustable feet on the bottom off Unscrewed all of the face screws on the front of the dryer Took the two screws off of t
... Read morehe back of the control panel holding the control panel to the metal frame. Gently pulled on the control panel to reveal 4 screws under the control panel to be able to take the front cover off. Pulled the front cover off (the dryer door front cover). Pulled the dryer vent cover off (two screws). I could now see the heating element with sensor/fuse (right side). Did a continuity test (beep) on all visable sensors/fuses on the heating element. No beep on the thermal fuse (used website diagram to locate parts to test and replacement part numbers). Got the part after about a week, tested the parted (it beeped), replaced with new part and put dryer back together, plugged in and the dryer heated. Problem solved.

No Heat to my Dryer
1. Had to find out what was causing the problem by eliminating each part one by one using a multimeter. I got a video link from parts select on how to do this.

Dryer would run with no heat
I actually went to mr fix it on u tube. Great instruction on how to take dryer apart. First I unplugged the dryer. I found I could reach the heating system by removing the lint tube in the back of the dryer. I put my I phone with the light on inside the back of the dryer and tested the connections to see if all were working. The thermal f

I then used a vacuum to clear any lint from the back of the dryer and inside the dryer. This took me about an hour and a half. I did it this way because I did not want to disassemble the entire dryer to get to the components. I received the fuse in 3 days and tested it. It was fine. I then put it in the dryer screwed it in place, connected the wires. Replaced the lint tube. This took about 10 minutes. Dryer is running great.

On my LG electric dryer my cooling light stays on. The dryer runs but will not heat up? What could the problem be?
For model number DLE2250W
Hi Miriam, Thank you for the question. I suggest testing the Thermistor,PartSelect Number: PS3529026. When testing you will test for resistance. At 70 degrees the resistance should be 9.3K ohms, 90 degrees would be 7.7K ohms. at 100 degrees it should be 6.2K ohms, 120 degrees 4.3K ohms. If the thermistor reads outside of range then it needs replaced. Hope this helps!

Our dryer was not drying or heating up at all! We changed the high limit thermostat and it heated up for two minutes, then it quit heating again. Can you help?
For model number DLE5955W
Hello Nicole,
Thanks for your question. There are a few parts you will want to test with a multimeter for electrical continuity. Replace any that do not show continuity. Test the thermistor, thermal fuse, temperature sensor, and the heater.
I hope this helps.
My dryer quit heating but will run i tested all thermostats and heating element all tested good except the thermal cut off fuse could this be the problem
Hello Cliff, yes this could be issue regarding your dryer not heating. 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.

Dryer does not even turn on. No lights on screen light up. Drum light does not come on ether. Ordered circuitboard from you folks after research. Did not fix problem. No activity on push button screen. If thermal fuse is blow will dryer lights light but will not start ? No one ever mentions this.Thanks !
For model number DLE1001W
Hi Larry,
Thank you for your question. If the dryer will not start, there are some parts that you will need to check to see which one is causing the issue. You will need to check the door switch, the drive motor, the thermal fuse and the belt. I hope this helps. Thank you and have a great day!

The dryer does start but does not heat up , there was a fair amount of lint and other debris in the vent hose but has since been cleaned out..l read the dryer will not start if the fuse is blown , is that correct ?
Hello Tony, Thank you for your inquiry. That is correct. Lint buildup can cause the dryer to overheat and blow the thermal fuse. You should also check the high limit thermostat as well. Hope this helps!

It takes about two hrs. To dry a normal load of clothes. Checked vent lines and filter all are clear. Actually been like this for several years. Looking for any ideas you might have. Thanks!
For model number DLE8377WM
Hi Robert, Thank you for the question. There are a few parts you can check. There is the sensor, PartSelect Number PS3529161.The sensor controls the temperature in your dryer and will turn off once your clothes have reached the desired dryness level. If you notice that your dryer is not giving off enough heat to dry the clothes or is taking too long to dry, this may indicate that a repair to the senor is required. You can also check the Thermistor, PartSelect Number PS3529026.This dryer thermistor temperature sensor helps monitor and regulate the temperature inside a dryer. Hope this helps!

If the thermal fuse is no good will it show an open on a continuity test?
For model number DLEX5101V
Hi Peter. Your meter should read 0 ohms of resistance if the fuse is good. If the display/needle does not move that means it is a bad fuse. Thank you for your question and good luck with your repair!

Will a blown thermal fuse keep power from going to start switches and display panel?
For model number Dle2516w
Hello Mike, thank you for your question. Yes, this part can cause the unit to not start, but it shouldn't cause the control panel to go out and lose power. You can test the fuse with a multi meter to see if it has failed. When tested the part should read zero or close to zero when tested. I hope this helps!
