75142 LG Dryer - Instructions

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.

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)
