79691393610 Kenmore Dryer - Instructions

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.

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.

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.

Exchange

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.

Repair was easy, but the part does not come with directions. It is pretty self explanatory if you are used to taking things apart and fixing them. Otherwise there are YouTube videos you can pull up. Dryer runs like it is new again though and it was way cheaper than buying a new dryer.

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.,

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

Pull filter out and replaced with new one.

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

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.

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

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.
