DLE7400WEA (ABWEEUS) LG 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.

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.

Exchange

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

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.

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.

Removed the old vent trap 3 screws total and replaced the new very quick and easy.

Ordered a new Dryer Lint Filter Assembly that fit my LG electric dryer.

Removed the top, the control panel and the door. The heater assembly came out thru the front, without having to remove the drum. Easy replacement

Watched a repair video. Very easy to replace, about an hour to repair.

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 did as I was told (by my wife). Bought the machine from Home Depot - no side vent kit - had them complete the installation today when the kit came.

My cleaning lady brought her handy husband over Saturday to help me. The only tool we used was a Phillips-head screwdriver. I went online earlier in the week and found a good video put out by Repair Clinic and another one I found on You-tube on how to disassemble the dryer. After watching several times, I knew I could do it. We worked together, I cut my hand on the inside edge of the control panel, but, when I hit a snag, we watched that part of the video again and worked right through. Replaced the Thermistor, NTC first, not a problem. Then the Heater Assembly, not too difficult. I couldn't find where one of the remaining parts went, so, we reassembled the dryer and gave it a try. Worked like a charm. We did remove a lot of lint from inside the cabinet and around the felt liner on either end of the drum. It works like it did when it was brand new. Highly recommend to work with someone, so, you don't get frustrated. I am 65 years old and this was a no brainer for me, although I am somewhat mechanically inclined. Very empowering to accomplish this repair. Just follow the video.

Removed the heating element, tested it, purchased a new element and installed.

After replacing the wires and the heat thermostat I realze that I needed to replace the thermostat ntc and the thermostat to blower located under door was burnt during fire. I removed front panel,front facing and tumbler to reach thermostat inter wall. It was easy after fixing to other area prior. I thought it was very easy and didn't cosume much time. I'm a women and it was easy to fix.
