8157 - Instructions

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 descr ... Read more iptions 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.

Followed the instruction on video.was great after three parts now is OK .we have heat.still cheaper than having it service.

Repair was easy, but the part does not come with directions. It is pretty self explanatory if you are used to taking things apart and fixing them. Otherwise there are YouTube videos you can pull up. Dryer runs like it is new again though and it was way cheaper than buying a new dryer.

Viewed YouTube video form parts select to take dryer apart. Very easy to do if you just follow instructions in the video. Nothing too hard to do. Of note the 4 pack roller assembly is a whole unit, so you’ll have to replace the stem unit the old rollers use and not just replace the roller wheels like in the video. That is a different part ... Read more number from LG. The front 2 are pretty straight forward to unbolt and replace. The back 2, especially one on the left is tighter clearance even with a wrench. If you’re able to pull whole dryer out and take back off, it’s an easier to get the one on the back left.
Also replaced belt just because i had it open, I replaced thermistor previously after getting a Te5 code about a year ago so that helped in taking it apart.
Would recommended doing it all since you’ll have it open.
Once replaced, everything ran again.

Removed the top, the control panel and the door. The heater assembly came out thru the front, without having to remove the drum. Easy replacement

watched the video on line then did the repair, very easy to replace

There’s all sorts of videos on it I watched. It was actually very simple

Unscrew the screw, remove old part, place in new part, replace screw and you are done.

Simple replacement

An appliance repairman determined the problem which was that it needed new pulleys and thankfully PartSelect carried them. He installed them in an hour and my dryer runs fine now.
