79690441900 Kenmore Dryer - Instructions

One of the roller assembly froze up & had a flat spot on it. There for causing the drum not to rotate. Pulled it out replaced the roller & up & running.

Pull off the top and front of the dryer and reached in and replaced the part it was easy. Had to clean all the dryer out real good with from the lint

Watched a You Tube video

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!

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.

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!

Followed the instruction on video.was great after three parts now is OK .we have heat.still cheaper than having it service.

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

Part showed up in 2 days and repair took 2 min. Very easy. Thank you!!

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.,

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.

Removed cover replaced bulb

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.

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.
