DLG3788W (ABWEEUS) LG Dryer - Instructions

I took the dryer apart. You have to take the top off, then the door/front off. There are wires & other parts that need to be unhooked as well. A flat tip screw driver can be used to pop the top off. The screws were all phillips. Once you take that all apart, then you can access the drum. I bought the belt because I thought that was what was wrong with it. Turned out to be hair in the drum rollers. Took those all off & put wheel grease on each of them, put new belt on (since I had it LOL) then put it all back together. Make sure everything is lined up correctly otherwise you will have to take it apart & reline (which I had to do)
I am a 49yr old female & was able to do this repair on my own!

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 repair video provided in the order confirmation email. Was easy.

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.

FIRST REMOVED THE LID ON TOP OF DRYER.THEN THE CONTROL PANEL AND THE STEAM TRAY. HAVE TO UNCLIP TWO HARNEST CONNECTORS. REMOVED THE FACE PLATE THAT HOLDS THE DRYER WALLS TOGETHER ALSO REMOVE TO SENSOR HARNESS CLIPS. .REMOVED THE BELT FROM MOTOR. TOOK DRUM OUT . UNCLIPPED MOTOR COLLAR SNAP CLIPS DISCONNECT THE MOTOR HARNESS. INSTALL NE MOTOR AND CONNECT HARNESS INSTALL CLIP . REINSTALL DRUM AND PUT BELT ON. CONNECT HANESSES AND INSTALL FACE PLATE. INSTALL CONTROL PANEL AND THE TOP LID.

Slide out old filter then slide in the new one.

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.

Followed YouTube video repair process. The only problem is that the door hinge has plastic bushings attached. A couple broke and the parts listing does not show the bushings, nor does the hinge come with them. The door is a bit loose without them. Nonetheless, the repair did the job for now.

After trying duct tape to fix the tear, I decided to see if I could just order a new one. Part Select was the first company I found listed, so I ordered one. It was not expensive and it was delivered very quickly! It works so well s as me I’m a very happy customer!

Followed video provided on site

I assumed this was a belt problem. Ordered the belt and followed the excellent screw by screw instructional YouTube provided by PartSelect. In fact, I probably would not have attempted the repair, until I watched the video and was reassured that I could do it. When I got the front panel off, the problem was obvious. There was a dishrag stuck in the blower. Didn't need the belt, but the video was sure worth the price of the part (~$17). Mr. Appliance charges $109 to DIAGNOSE the problem! This was way easier than dealing with them, especially during a pandemic near the holidays.

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

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.

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.
