90441 (ABWESEC) LG Dryer - Instructions

One of the roller assembly froze up & had a flat spot on it. There for causing the drum not to rotate. Pulled it out replaced the roller & up & running.

Pull out the worn out dryer filter and replaced it with a new filter that I purchased through Partselect.com.
It fit perfectly.

I took the old lint filter out and put it in the garbage. I the put the new lint filter in the dryer. Problem solved

I replaced the thermistor, then the gas ignitor which were easy to get to once the drum was out. The gas is still not igniting so not sure where to go from here. Putting the drum belt back on took some muscle. But then I'm 71.

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

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.

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

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

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

Completely had to dismantle the dryer to get to the igniter.
The screw holding the igniter is a SOB to get at for extraction, and even worse putting back.,

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.

Pull filter out and replaced with new one.

Slide out the old lint catcher, and slid in the new one, not that hard.

Opened front of dryer - removed drum - replace all 4 rollers (2 had bad shafts) - replace drum with new belt - reassembled

Despite the young age of this dryer, and failure of all the other trials to fix the problem, I figured maybe the igniter is the problem. Ordered one. Followed a U tube video to take the unit apart. Noticed immediately that there was lots of lint pretty much everywhere inside the cabinet. Come to find that the blower and the vent had never been connected, with about two inches gap. So, some of the exhaust was going out the vent hose, but lots was not. In fact, lint had coated the propane jet and the air mixer assembly. Replacing the igniter was not particularly difficult, once the dryer was in lots of pieces. I did not test the igniter before replacing it. I did connect the vent outlet to the blower and secured it. End result was a perfectly functioning unit and a happy wife. I don't recall reading about this as a possible cause of propane odor and failure of the unit to heat up.
