LG Dryer shuts off early. Moisture sensor fix. 

Lots of simple repair procedures like this ..posted on RU-vid help numbers of ‘do it yourself-ers’ ..which is what I am ..a simple search provides the fix ..thanks for this ..much appreciated ..and ..yes ..great explanation of the basic circuit design ..ultimately allowing for a simple cleaning of the sensor surface without removal from the drum ..and ..done! ..

THANK YOU for this video, I followed every step you mentioned and my dryer is working again!..

Good tutorial , I did not take out the lint trap, I just reached in and clean the sensor with alcohol and sand paper since it was visible. Save me from buying a new dryer.

I just bought a brand new LG dryer and this sensor keeps stopping too. So it is def not dirty or anything, it just sucks. I just don't use the sensor option, but turn the knob all the way to the right where it says Manual Dry, Speedy Dry and Choose Time Dry to select how long you want to dry it for. Thank you for your video, this is really helpful!

Thank you for this video. My BRAND NEW samsung smartcare dryer, in my BRAND NEW home was not drying clothes completely, so I went through all the trouble shooting things I knew of, make sure the vent hose wasn't bent or blocking the exhaust, make sure the vent itself didn't have construction debris in it, made sure the gas line was connected correctly and the valve was open, checked and yes the dryer would run, yes it was heating quite well, yata yata, but nothing would actually be dry so I sat there and watched it go through a complete cycle (an hour and 16 minutes on max settings) but it stopped after 52 minutes, checked the clothes, still damp. Re-started the cycle, it shut off after 13 minutes. So I started looking online. The samsung website says "clean the moisture sensor with a damp rag with a drop of liquid soap". That didn't do squat. THIS however (sandpaper and rubbing alcohol), worked.

You sir are a scholar and a gentleman. Much appreciated

Thank you for posting this. My GE profile dryer has similar sensors. After following your instructions my dryer works great.

Good video. I just had the same problem with my LG dryer and it would only run for about 15 seconds before stopping. I cleaned out the area under the filter as it was very full of lint, and this still did not solve the problem. Finally I thought as you said that the sensor was not working because it's surface was dirty. I cleaned the contacts off with some 3M Scotchbrite material and now it is working fine.

I had a suspicion that this is how this sensor worked. Thank you for your in-depth explanation!

The issue is caused from bounce sheets, causes a wax-like build up on bars. Use a green scotchbrite pad to clean. If testing with a dmm put probes on terminals then put hand on both moisture sensor bars, if ohm reading changes its good. Then you have another issue such as plugged wall vent..

Thank you so much, I have a Miele and checked all the usual components the other night after work but with no success. So the thought of stripping it down again this evening was not very exciting! With your inspiration I just scrubbed with a coarse scotch brite and is working! No tools needed thank you thank you thank you😊

Great demonstration, troubleshooting, and resolution. Thank you for sharing.

Thank you so much for sharing this video! You probably saved me a couple hundred dollars on a repair bill!

Brother thank you so much for your knowledge and help. This video helped me so did all the dirty work and fix my dryer. I sanded and cleaned my moister sensor along with the gas igniter sensor under the dryer. God bless you and your family 🤝

I am so grateful for your expertise and my ability to take the steps to attempt to repair my awesome LG dryer thank you so much. I didn't have sandpaper so I improvised with an Emory board and alcohol wipes. Happiest holidays 🎉

Very good explanation and demonstration. I suspected there was a film on mine because i had the same reading with my ohm meter. This video confirmed my suspicion. Thanks!

Thank you for your video, because of it I was able to buy a really dryer and just had to clean the sensor all for just $20 your awesome!!!

NICE. ultimate professionalism good science

Great video this helped a lot and was very straightforward Thank you for posting 👍

My LG dryer has been shutting off early (about 10 minutes in on average) during the dry cycle. I will definitely give this a look and give what you did a try. Thank you for posting this! I checked continuously of the sensor bars and got low resistance readings on both (I use the diode tester function on my Fluke and got the solid beep on both). I didn't go rail to rail and use a damp cloth across them to measure the resistance, need to try that next. At this point, I can't see the problem being the sensor elements.

Fantastic video…fixed it straight away…thanks!

Thanks a million

Thanks for making this video...My LG electric dryer DLEX8000V is showing 4 bars on the flow sense indicator light and I have extensively cleaned out all my ducting all the way to the exit exhaust fitting outside my home...Even after removing the duct to the wall from the dryer it is doing the exact sequence you mentioned: It is 41 minutes reading on Normal...then it quickly drops to 9....and then 6...until it turns off way too quickly and shows d 80...but it is fine in heavy duty or even jumbo dry...crazy huh? In Diagnostic Mode the following codes cycle before any tests U 10...d 12...15:E5...In the moisture test the number went from 237 down to 68 when I put the damp cloth across the sensor bars...so it seemed like it passed...I also ran the other two checks for temp and started at 35C ended up at 74C before declining very quickly to 68C then back up to 76C...whoa...is that good?...the range should be 5-70C...and pump AD value is 14-15...I am having problems getting my plastic housing out that contains both moisture bars...mine is one piece instead of having two screws like your model dryer...Can I just unplug my dryer and wipe down or polish those bars while it is still assembled?.. I wanted to confirm my guess that I have to remove the door and the front cover to access a screw(s) that hold the darn lint holder in place if I MUST remove it...thanks for any suggestions

Great info Hoping this works for ours

Going to try this. I've regretted buying my dryer since day one. Maybe this will fix it.

You just saved me from a fat invoice from Best Buy. Thanks so much!

Very helpful video!! What would you recommend for a dryer that’s brand new? Surely there’s nothing built up on the sensors. It stopped drying after 10 minutes the first time I used it, and the clothes were definitely still wet.

Thanks a ton!

This did the trick! Thank you!

That worked! I didn't even take the sensor out.

Good idea and great job!

Thank you, but in the latter part you were not showing the meter. So how do we know if the sensor is actually good, because while there was no conduction, the meter was also emiting sound.

This fixed it for me msn thank you so much

Freaking awesome! Thank you for your help!

Thank you so much for sharing 🙏🏽

Thank you for video 🙏👍

my boy hitting it with the ol ohm meter, also with the fiber splicer- chem wipes and alcohol dispenser. sick.

Not sure I would use sandpaper. It seems that could remove too much metal. I'm trying Scotchbrite (blue) since it's just a film that I am trying to remove. I'll let you know if that worked.

How come you didn't show the meter when it was "good" ? What numbers were the meter supposed to show?

Use a scotch bright pad, not sandpaper. Sandpaper will put scratches in the surface and allow dirt to accumulate.

great video, thank you.

My new hero!😊

I cleaned mine with alcohol before, and it didn't fix it as well. It didn't occur to me to test with the multimeter! Thanks!

Great video

Since the moisture sensor use DC current, one element always goes to the ground. So, it does not matter which wire goes where. My Electrolux has a blue and a white wire. The white does to the ground terminal. But it does not matter since these are two isolated elements. The moisture in the clothes provides resistance over the two elements. Less moisture, less resistance. Based on OHMs.

I just bought this dryer week ago now keep shutting every 10 min m gonna return it to best buy

Great video. We have a Samsung with the same issue. I'm wondering if anyone has simply disconnected the moisture sensor successfully without generating an error code or rendering the dryer inoperable. Anyone?

Hi, I don’t have a way to test my sensors but I’m having an issue with my dryer stopping usually after 1-2 min of starting it for the first time. I then open and close the door and start it again and it runs the complete time for the cycle. Could it be my sensors?

Great Video. My GE dryer display works but i hear click and single beep only when I press start button. is it possible that safety switch is not working or might be moisture sensor as well ?

I think you unplugged the wrong plug. That's a 110V plug you just unplugged; the dryer is 220V - You're gonna get zapped 😁 - I used some steel wool to clean and that did the trick.

Merci je viens d'arranger mon GE , sa m'évite d'acheter tout un gros morceau de $275

Could you have left the sensor inside and still clean it?

Ok hold on...I get that your unplugging your dryer but not everyone has a gas dryer with a 120v plug. Might want to inform everyone that if they have a electric dryer they will need to unplug the bigger 240v plug. It will either be a 3 or a 4 prong plug. Or if they know what circuit breaker there dryer is on they can do that as well. However it is much safer to unplug it from the wall.

LG electric dryer error code after 3min EE2, replaced thermistor, , would work on delicate, still gets hot.

In your opinion, my dryer starts 40 minutes, get to 38 minutes then drops to 1 minute then does it tune and cuts off. Do you think it could be the moisture sensor bars

Question! Did you try cleaning (scuffing up) the metal bars to ensure there wasn't a buildup from chemicals in detergents? Just a theory I have since the bar should be conductive throughout. The bar still is solid, so my theory of buildup seems to be plausible? Just wanting to see before I purchase a new piece? Did you try this?

Will it work without the sensor? What’s the main purpose for the sensor?

Any idea why it stops running after about a minute?

stupid question. Couldnt you just jump the wires and eliminate the sensor? The dryer should shut off after timer then?

My Samsung dryer on Timed Dry mode so no sensor being used, goes from 40 min to 39 to 1 it only “heats” for 1 minute and then switches to cooling and then done. Any idea what could be wrong?

Why can't I just buy an old school dryer that that does not have any sensors, that does not have any complicated digital screens, that doesn't have any wifi, that has 2 buttons, that does simply dry my clothes and last me 40 years?

Here is my question: If my dryer is running for only a few minutes and shutting off but stays on while I’m running it on air dry then it’s more likely to be the thermostat, right? Common sense says that if it were the sensor, it would shut off while on the air fluff or air dry or whatever that mode is lol Right?

🌹

so..my Samsung machine is not shutting off in moisture sensing mode...it just stays running in heat mode. Probably not a moisture sensor problem or a moisture sensor wiring open since current must be being detected by the controller to run the system- (assuming the control board is working properly). I'm thinking the controller has got a problem.

I replaced mine with new sensors and it still doesn’t work The dryer turns off in 10 minutes Any suggestions

Is there any way I can just put my washer on an auto pilot where it just dries and doesn't worry about sensing moisture?

I’m trying to fix my LG dryer. My 10 year old son put extra soaking wet clothes in the dryer.now it wont spin. lights turn on.
