How to Troubleshoot & Replace Lg AP4440975 / 6931EL3003D Dryer Hi-Limit Thermal Fuse

Replaced thermostat and heating element on dryer. Less than $200 repair, cheaper to fix than $1200 new one. 

I decided to replace the Heater Assembly and Thermistor since I didn't want to disassemble and re-assemble the dryer several times trying to figure out exactly which part was an issue. For $172 I replaced all the parts that deal with heat. Was most likely the Heater Assembly. It was full of dryer lint/dust. Amazing to me how much lint and dust gets inside the cavity of the dryer and how in the world it's never caught fire is a miracle. I took the time to clean every part that was removed especially the lint filter area. It had a LOT of lint trapped down below the actual lint filter. Vacuumed out the entire dryer cabinet. Runs like new again. Be sure to search YouTube thoroughly for videos on how to do this repair. 

Replaced both exhaust vent thermostats. Repair video was extremely helpful. Just placed my laptop on the neighboring washing machine and used the pause button between each step. Took less than an hour to switch out th e parts. Probably saved 150 $ in service costs. Maybe more since there isn't an LG service center in my city!! 

Watched appliancepartspros how to videos and was able to fix the problem, ordered parts one day and they were delivered the next.

Took the dryer apart to test the heating element, thermostat and fuse. After determining the thermostat was faulty, I ordered the thermostat and installed it. The problem was fixed. 

I went on this site searuched for the se issue as mine. Saw the videos on how to install Parts video and Bam. Done deal. 

The hi-limit did the trick. Thanks for giving your probability info. I suspected that that would be the culprit but it was nice to have the second opinion. A lot of the time spent was dealing with blowing out the lint. 

Researched possible causes, diagnosed the problem with a mutlimeter (thermal fuse was bad, thermostat, and heating coil were fine), ordered a replacement thermal fuse, installed and everything was good.
