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.

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 the 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.

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 fuse was not working. I removed the two wires , red on top and white on the bottom. Then used a small Phillips screwdriver to remove the two mounting screws and removed the fuse. 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.

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.

igniter would not light

Initially replaced igniter. Didn't think it was bad though. Read other suggestions on another website. None were the correct diagnosis for my situation. And when I figured it out they did not offer correct part. The dryer thermistor temp sensor (probe sensor) is what I replaced. Found it on Parts Select. I did replace other parts also. But that's the one that ultimately was the issue.
Was not hard at all if one is even a little handy.

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. To access this part, you will need to remove the front bulk head. To remove this, you will need to remove the screws securing the top. Uninstall the screws that support the control panel and lift. Remove screws holding the support bracket in place so you can detach this piece. Detach the wire harness and remove the wire, then set the bracket aside. You will now open the dryer door and release it by taking out the bottom two screws. Disconnect the wire harness and moisture sensor wire harness, remove screws from front bulk head, and remove screws that secure the duct housing. You should be able to completely remove the bulk head. You will find the sensor underneath the lint filter grill, which will also need to be removed.

Customer Repair Stories

HST code given by dryer

Called LG on the phone and they gave the button presses for diagnostics, which then gave the HST code, saying the Humidity sensor was bad.
The part was described as the Humidity sensor module. Actually it's just the wire leads for the sensor which must be electronic and only accessible by disassembling the dryer. There were descriptions about cleaning the wires, perhaps because some people use dryer sheets which cause a buildup on the wires and prevent them from doing their job. I use wool balls and have no buildup on my wires and replacing them did not fix the sensor, because the module accessible inside the dryer is not the moisture sensor, but only the wire leads.

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.
