79669278000 Kenmore Dryer - Instructions

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

Removed the old damaged filter and replaced it a new one.

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

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 repair video provided in the order confirmation email. Was easy.

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 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.

Opened front of dryer - removed drum - replace all 4 rollers (2 had bad shafts) - replace drum with new belt - reassembled

Followed video provided on site

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

I took the top off, I disattached the front and took the front top of dryer off, taking the front of dryer off, detached the belt and took the drum out, found the wheels took the plastic triangle off and took the wheels off and replaced wheels, then did everything in reverse and no more thumping. just remember to unplug unit before working on it. And also Part Select is a very good site and place to get parts, very fair priced and very professional.

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. '

You will need a helper. Dismantle the Dryer: Remove the screws that hold the top cover, front control panel, front door and front panel. Release the V-Belt under the drum. Remove the Drum. Removed and replace the 2 Front roller assemblies - these were completely worn. Replaced the 2 rear rollers (did not replace the rear roller axels as these were more difficult to remove and they were in good shape) and the V-Belt while I had the whole thing open. Use a shop vac and cleaned up the whole unit. It is so nice and quiet now.
