71512 LG Dryer - 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 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 installation of the gas orifice was actually simple. Unscrew the old orifice and screw in the correct orifice. Tricky part of the process was accessing the area of the gas valve.

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.

To install the repair part took about 5 minutes. It took a couple hours to take apart of put back together. Unfortunately the part I replaced was not the problem. I still have no heat. My own fault for not testing the parts before ordering. It seems there is no ignition of the gas for the hot air flow. I would be grateful for any suggestions. The video was FABULOUS...really step by step, screw by screw. Thanks for that. Barb Swenson

I took the top off, I disattached the front and took the front top of dryer off, taking the front of dryer off, detached the belt and took the drum out, found the wheels took the plastic triangle off and took the wheels off and replaced wheels, then did everything in reverse and no more thumping. just remember to unplug unit before working on it. And also Part Select is a very good site and place to get parts, very fair priced and very professional.

I had ask how to get the top off., it was simple ,take 3 screws off the bottom angle bracket .and slide top back about 2" then lift.then remove the front panels. '

Removed Top, then front and drum. Parts easy to access once drum is out. Recommend reading up on drum replacement. Would appear that all repairs will require taking it out.

First I just replaced the ignitor on a hunch, (disassembly was easy once I saw the video) I also examined the high limit thermostadt and found it was tripped, so I reset the button. the dryer fired up, but soon the thermo tripped again. I found that I could reach it with my arm placed in the inspection port,( about a 4 inch diameter pop out) make sure you unplug first, find the button near the ignitor, and pop it in. the high limit thermo was only holding a few seconds, so I decided to replace it, and did a "shot-gun" approach, replacing all thermos and thermisters at once, only about 35 bucks delivered...BTW, PartSelect shipped them to me at the speed of light.....one day ! Ireplaced all thermos and did and extra scrulpoulous cleaning of the vent. NOTE: it is completely possible that ahe only problem was a reduced vent capacity cmbined with summer heat leading to tripping the high limit thermo....however the thermo was tripping waaaay too easil in my opinion. Anyway, I celebrated doing 10 loads of piled up laundry, and basking in the glory of my wife's admiration for saving a $1000. appliance replacement. "how did you know how to do this honey?" "yoir so smart" (i did'nt tell her about the PartSelect video)

Seemed to be shutting off on the safety thermostat so I replaced them all. Works.

This was a repair from a repair. It started as a conversion to LPG, in the process the igniter broke. The parts arrived quickly and we were able to get it back together and the wife is happy. Thanks.

Unplugged dryer. Removed front panel. removed nut holding old igniter. Unplugged old igniter, plugged in new igniter, and mounted new igniter with screw using nut driver.

After replacing the wires and the heat thermostat I realze that I needed to replace the thermostat ntc and the thermostat to blower located under door was burnt during fire. I removed front panel,front facing and tumbler to reach thermostat inter wall. It was easy after fixing to other area prior. I thought it was very easy and didn't cosume much time. I'm a women and it was easy to fix.

Not knowing whether it was the pulley, tensioner, or drum roller I had previously pulled the dryer apart and noticed one roller shaft was rusty for some reason. When the part came in (which was quite fast)I disassembled the dryer to the point that I could remove the left rear drum roller. Replaced the roller and reassembled the dryer (to my surprise without any extra screws or parts left). Fairly easy job, just time consuming.

removed the top of the dryer first by removing screws in the back and pulling the top back and up. Removed the control panel, followed by the door. The front panel and top brace were then removed. The belt was disengaged by pulling the tensioner idler and working the belt off the motor pulley. The drum was lifted out and set aside with the other parts. Holding the motor shaft with vice-grip pliers, and turning the nut on the blower wheel (left-hand thread!)removed the blower wheel. The motor is held by snap-on retainers and easily removed and swapped. Installation is reverse of disassembly. While in there, cleaned out the lint gathered everywhere. Also constructed a heat shield out of aluminum flashing and foil tape to cover the foil and foam tape between the burner assembly and sheet metal side. The foam had actually burned at some point in the past and the flashing should act as a better heat shield. A relatively easy repair, but should not have been necessary in a 7 year old dryer.

Unplugged the dryer from the wall. Removed the back bracket holding the top on. Then the top will slide back and lift off. Next I removed the screws holding the control panel. Removed the door. Removed all the screws holding the front cover on. Removed the lent shoot. Manually rotated the tumbler. Checked both rollers in the front. Found one with the flat spot in it. Removed and replaced it.
