DLGX4271V LG Dryer - Instructions

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.

The lint screen that this company sent was 3x too large. I called to return/exchange it. No one available - go to customer service.
I went to customer service and entered my email address and the order number (while I was looking at the original order1). The email and order number could not be found.

I am still waiting to hear from someone from the company to get a RMA and return label! Will NEVER use this company again.

Replaced idle pulley wheel, worn drum belt and all 4 rollers (1 frozen) due to dryer age. Site video re general disassembly/re-assembly easily adapted to this model and very helpful with exception of replacement of drum rollers. New rollers received (AGM75510755) were pre-mounted on included shafts. This required removal of existing roller shafts to replace with new shaft/roller units. Site video shows placing a new roller on existing shafts after removing a plastic retaining clip. New roller/shaft assembly is a better option and fortunately I did not order extra retainer clips! Rear drum roller shafts have small carved out space to fit a box end wrench to remove shaft nut. Watch out for sharp edges on internal steel parts!

When manufacturer confirmed the part would fit without an adapter, it was the easiest DIY task ever undertaken.

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.

Removed cover replaced bulb

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.

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.

Unscrew the screw, remove old part, place in new part, replace screw and you are done.

With a thin flat screwdriver I was able to pry out the old door switch, I replaced it with the new door switch, pushed back in dryer and so far is working since I installed a month ago.

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.

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.,

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.
