LG Dryer shuts off early. Moisture sensor fix.

[@fheflin21]

You, sir, are absolutely brilliant! Without your help in the video I would have spent a ton of money to replace the control board and probably a service visit which would not have even fixed the problem. Amazing when you look at the two metal strips, which I did before watching this, you wouldn't image there was a film on them thick enough to block it's function. Followed your directions and we are back in business this morning. You're awesome. Thanks for taking the time.

[@Hengebobs]

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.

[@Another_Bad_Creation]

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.

[@christalightauditoriumeven9949]

You sir are a scholar and a gentleman. Much appreciated

[@fringeminority5676]

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..

[@Icefreez]

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

[@StevevonC]

So far, this is the only explanation I’ve found for the symptoms and the corrective action seems to be effective. Had very similar resistance measurements before and after cleaning, so hope this solves the problem. Testing just finished and seems to show that the problem is corrected.

[@donaldstark1164]

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.

[@jamesleiter4222]

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

[@j3d3d1ah]

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!

[@lynetteturner223]

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!!!

[@jungapo2]

thanks for sharing i don't know about this until i saw this video. wow, the metal bars looked clean not until you checked it with ohmeter.

[@victoryvisiontour]

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!

[@mickyjay249]

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😊

[@liliannstudsrud4763]

[@texbacalian5036]

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.

[@T800-x6s]

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!

[@michelleortiz7300]

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

[@signalsandbits]

On my dryer I could of polished them in place. I only removed them to show what they look like and explain how they work. Either way make sure you unplug it first.

[@fattymatty1904]

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

[@Sypsey]

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

[@desertdiyer]

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.

[@signalsandbits]

Manually set the time to more than 10 minutes. This will bypass the sensors because you set it to a specific time (that's how mine works). If it still shuts off early then its likely not the sensors. Other than that, I would contact the manufacturer if its new they usually give 90 day warranty. Under the warranty they would send someone to your house to fix it.

[@JonnyDoe1776]

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.

[@Slipshott]

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

[@signalsandbits]

I was testing for continuity the meter just needs to beep

[@fishman211]

Thank you. Good video and will be helpful. I do have one question. I'm assuming (yes, I know) that you're removing a standard plug from the outlet for illustration purposes only. My LG takes a 4 wire 240 installation. Am I correct?

[@signalsandbits]

They can be different Mine is 120V. Mine is a gas dryer your might be electric. You should always unplug it when working on it.

[@SarahMilesSmiles]

This is probably a dumb question, but would optimal behavior be a continuous sound no matter where you placed the red and black leads (so long as they're along the same bar)? Patchy sound comes from minute differences in where the leads touch as you're measuring, so it's showing a presence of film (under at least one of the leads) in at least some areas? Something like the angle changing slightly as you hold maybe increasing the surface area from the very tip of a lead to along the side, upping the odds of finding a path SOMEWHERE between the leads, or sliding over a millimeter? And then no sound, so long as the device is on, means the area around at least one of the leads is pretty solidly covered? I THINK the sound is just binary - if there's a path from where the red lead touches to where the black lead touches. (I repair my own electronics, but circuit stuff is something I've no background in. Want to make sure I'm interpreting what's going on properly before I take something abrasive to the metal in our dryer. Have a cheap multimeter from Temu and have it set to test for connectivity, but since we can't see your meter the entire time, I want to make sure this is more about the sounds than any number displayed. Thanks for posting this video!)

[@signalsandbits]

It is about the sound. The beep means continuity. Since it is a solid bar it should be continuous. The reason it stops beeping is because the bar has a film on it . That's why I used the Sandpaper to remove the film. You can try a scotch Brite pad

[@SarahMilesSmiles]

​@@signalsandbits Theoretically, could you take the two places that wire connects to the metal bars and connect them together to bypass the moisture sensor? Closed circuit means clothing is still wet, so if you connect the two wires together, the dryer will always think clothes are still wet and run for the entire duration rather than deciding clothes are dry 10 minutes early and stopping to save power? I haven't removed the sensor yet to see those wires on our model (it's definitely the same part as yours), but it seems like it should work. Just don't know if there's a good pre-made piece to connect them or if it'd need wire stripping and twisting and/or soldering. People talk about having issues with that sensor if they do small loads, so doing this seems like it'd bypass a lot of potential trouble.

[@lasamples5254]

Thanks for the good info.!

[@ApplianceBlvd]

NICE. ultimate professionalism good science

[@bills6946]

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

[@GalaxyUnravel]

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 ?

[@JuanGomez-gb6ce]

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?

[@marshalldodge407]

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

[@alexwashington8785]

This fixed it for me msn thank you so much

[@carneyusaf]

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?

[@carneyusaf]

Then I keep watching lol... 😊

[@deemedmfg]

[@dwightkellingtons5308]

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

Yes probably. I wanted to do a visual inspection of the actual sensor. But that's a good point I will update the video description to include that

[@BitesizeTiff]

[@bpayton76]

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

[@signalsandbits]

It sounds like that may work but i dont know. But then everything would go for the full time so youre gas bill would go up.

[@jerrylohry2459]

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!

[@walterwebb]

Great watch it worked for mine.

[@rjerabek81]

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

[@signalsandbits]

Sounds like it could be. You can put it in manual mode by selecting a custom dry time like 20 minutes or something and see if it goes all the way to 20 minutes. The moisture sensor is not used when you select a custom time.

[@punja20sher]

[@Mindfreegardener]

Thank you so much for sharing 🙏🏽

[@EacProductions44]

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

[@signalsandbits]

The sensor is needed to sense when the clothes are dry. For example if they dry in 10 minutes you don't want the dryer running for the full 40 minutes (or whatever cycle time is) and wasting energy. I don't think it will work without the sensor.

[@Lipcrux]

[@lancewolf2451]

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.

[@signalsandbits]

If it keeps running past the set time then its probably something else wrong. Even if the moisture sensor is shorted it should still stop when the maximum time is reached.

[@stephandaudt4319]

Do you need to remove it to clean? Can you just unplug and tell if it has a layer of film on it?

[@Mallory1961]

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?

[@signalsandbits]

Mine goes into the sensor dry mode automatically. But if I change the dry time or use a custom mode then it does not use the moisture sensor. So try changing the dry time if it still stops before completion then it's not a moisture sensor issue.

[@lorenapcc1]

​@signalsandbits in that case, what is it? My dryer still keeps on shutting down and saying N95 and drips some water when we open it. We use the manual setting and dry on ultra low temperature and it still does it. We completely cleaned our vents. House and dryer are a few months old.

[@josephrodriguez8721]

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?

[@signalsandbits]

I'm pretty sure you can do that by setting the dry time yourself. if you set the dry time then it doesn't need the moisture sensor because you're telling it how long to run.

[@clara555alice9]

[@aidenhurd8486]

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.
