71433 LG Washer Dryer Combo - Instructions

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 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.

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.

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.

Followed video provided on site

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.

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.

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 did as I was told (by my wife). Bought the machine from Home Depot - no side vent kit - had them complete the installation today when the kit came.

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.

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.

You will need a helper. Dismantle the Dryer: Remove the screws that hold the top cover, front control panel, front door and front panel. Release the V-Belt under the drum. Remove the Drum. Removed and replace the 2 Front roller assemblies - these were completely worn. Replaced the 2 rear rollers (did not replace the rear roller axels as these were more difficult to remove and they were in good shape) and the V-Belt while I had the whole thing open. Use a shop vac and cleaned up the whole unit. It is so nice and quiet now.
