80448 LG Dryer - Instructions

I actually went to mr fix it on u tube. Great instruction on how to take dryer apart. First I unplugged the dryer. I found I could reach the heating system by removing the lint tube in the back of the dryer. I put my I phone with the light on inside the back of the dryer and tested the connections to see if all were working. The thermal fuse was not working. I removed the two wires , red on top and white on the bottom. Then used a small Phillips screwdriver to remove the two mounting screws and removed the fuse. I then used a vacuum to clear any lint from the back of the dryer and inside the dryer. This took me about an hour and a half. I did it this way because I did not want to disassemble the entire dryer to get to the components. I received the fuse in 3 days and tested it. It was fine. I then put it in the dryer screwed it in place, connected the wires. Replaced the lint tube. This took about 10 minutes. Dryer is running great.

I unplugged the dryer and disconnected the vent.
I pulled the dryer away from the wall so I had room to work on it.
Pulled the top cover off (slides back).
Took the door off
Took the front adjustable feet on the bottom off
Unscrewed all of the face screws on the front of the dryer
Took the two screws off of the back of the control panel holding the control panel to the metal frame.
Gently pulled on the control panel to reveal 4 screws under the control panel to be able to take the front cover off.
Pulled the front cover off (the dryer door front cover).
Pulled the dryer vent cover off (two screws).
I could now see the heating element with sensor/fuse (right side).
Did a continuity test (beep) on all visable sensors/fuses on the heating element. No beep on the thermal fuse (used website diagram to locate parts to test and replacement part numbers).
Got the part after about a week, tested the parted (it beeped), replaced with new part and put dryer back together, plugged in and the dryer heated. Problem solved.

1. Had to find out what was causing the problem by eliminating each part one by one using a multimeter. I got a video link from parts select on how to do this.

2. Then got another video link sent to me by parts select on how to take my dryer a part and replace the part.

3. Followed it step by step and it worked really well.

4. The process was great except shipping was excessively high for such a small part.

Replaced thermal fuse

order start button and was sent thermal, reordered and rep sent me a button that was not for my machine even though she had model no.,called third time and was told I had to order new control panel but they were not being manufactured any more.so it is not fixed

Entered dryer from rear exhaust port. Removed 2 screws and 2 clip on wires. A little awkward of process but superior method over disassembly of drum and main parts.

Initially replaced igniter. Didn't think it was bad though. Read other suggestions on another website. None were the correct diagnosis for my situation. And when I figured it out they did not offer correct part. The dryer thermistor temp sensor (probe sensor) is what I replaced. Found it on Parts Select. I did replace other parts also. But that's the one that ultimately was the issue.
Was not hard at all if one is even a little handy.

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

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.

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.

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.

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

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.

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. '
