- How to reset your LG fridge and run diagnostics with a test button on the PCB board. If you have problems with LG linear compressor refrigerator not cooling or not working at all, you can put it in the test mode with a reset switch on the main control board, which consists of inverter and motherboard. Resetting LG refrigerator may fix some problems, or a number of error blinks on the PCB board will point you in the right troubleshooting direction.
ATTENTION - removing the cover from the PCB board may void the warranty, and exposes electrical components which can be dangerous. If you don't feel comfortable working with electricity, please don't do this test.

![[LG Refrigerators] Not Cold Enough](/img/n.gif)
Thank you. I did this last night on a previous yardwork customer who placed an advertisement in FB marketplace for a freezer not freezing repair. Watched your vid. Removed the service panel, did the steps after viewing 6 blinks of a red LED blinking. I watched for the test step indicator on the fridge's temp display. Fourth push went to "normal operation".
I called her the next morning. I was told her fresh food compartment and the freezer section are working as they should be.
Oh my goodness. I was afraid I would have to buy another fridge. I love my fridge. This video helped me fix/reset my fridge! A million thank you's!!
May 18, 2024 - I have a different and newer model LG fridge/freezer, but it is possible that some of what the host shows in this video may be of some help to me now and in the future. Thanks YourSelf for a very good video. "Live long and prosper!🖖🏻"😊
As a HVACR tech with little experience with appliances your videos are very helpful in allowing me to learn the correct way to trouble shoot these LG Frigs and not just assume like most techs I work with that it's a bad compressor every single time.
Glad you found it helpful, and thanks for watching!
@@Your-Self ⁰
Never got any lights flashing on the board
Thank you very much. The water line for the ice maker sprung a leak and the PCB got wet. The fridge stopped. You showed me that there was a reset button and where it was. After things were dry I tried it (using a popsicle stick just in case!) and everything works again fine. Thanks for saving us thousands in fridge and food at the hottest time of the year.
Glad it helped, and thanks for watching!
Thanks for the video…
My freezer had gradually quit cooling and things were thawing. Lost a lot of frozen food as we were gone. LG has been very difficult to deal with even though it is under warranty. After viewing your video I found the test button and things checked normal. No LED codes. Compressor and fan function normal. Upon emptying freezer and dissembling partially the interior, frozen coil. I suspect the defrost system is malfunctioning. Took a while to find the test button, but my mother board is different (located on top of unit). Still your video was quite helpful. Confirmed fan operating as well as compressor. On a side note if this happens make sure you have plenty of towels for the thawing ice buildup. I don’t recommend trying to remove it manually as there are electrical wires and water lines in the area. I managed to do it but I have 40 years as an aircraft/avionics repair person. Waiting on LG warranty people now…🙄.
Thanks again!
@@elliottsmith2179 - You'll be waiting a long time. LG is a crappy company. Basically consider it Eastern China. They just had a class action against them for their defective refrigerators, but my model was not included - even though I am sure they know they used the same defective engineering and parts in other models, they will not do the right thing without a lawsuit.
I am in Hot California, have been helped to solve air conditioning issues and , I felt that I should Express my positive message to those persons that HELP UNKnown people through the invaluable service of the internet . Those topics that gives assistance on soloving high temperature or issues on air conditioning etc, I should be really thankful with those great humans that give clear, counsels or solutions . THANKS GREAT HUMANS WE NEED MORE PROCTIVE HUMANS LIKE YOU THANKS!
what is PCB
My LLFX28968 stopped cooling after our home AC quit working over 100 degree weekend in Texas. Watched your video, found a code 6: Current Overload flashing after I removed back panel. Ran the self test, everything appeared to be working so I waited thirty minutes then closed it back up. I guess it went overcurrent due to 90 degrees in the house but seems like it's working fine again. Thank you.
Great video. I'm a technician and appreciate your emphasis on safety. Great information.
Much appreciated
My LG compressor broke in the 4th year. I'm so glad I still have a warranty up to the 5th year. Never again will I get an LG refrigerator.
NO Samsumg, whirpool or LG all they are TRASH, only 3 years working life
Mine stopped 5 days after 5 years warranty expired...never again will I buy lg
Very informative and straight to the point. Thanks!
Thanks for watching!
Will be subbing
My LG the model number is LMX25964 ST will not cool what is the problem
On the control board is it EBR 673480 could it possibly be the main control panel
Great video. Thank you! God bless.
Thanks for watching!
Best refrigerator repair videos, period!
Thanks for your video I have a 36" LG and the display would flash a error message after appearing normal after just plugging it in. This for 6 years, then the other day it completely stopped cooling. After watching your video I found the fan wire had fell off. A easy fix. Also the display seems to be working now!
Good to hear it!
Thank you for the video.
Thanks for watching!
Very helpfull! You earnt a new subscriber!
Glad you found the video helpful, and thanks for watching!
This evening discovered freezer not operating properly but fridge is fine. This will help immensely. Thanks
Good luck!
Very nice video. Troubleshooting my LG now. Upon first panel opening, the led was blinking but no longer after a power off / on cycle. Will open the bottom half panel to inspect the compressor and related fan work. Fridge and freezer almost at room temp. If compressor with '10 year warranty' then game over as LG was sued for this fault. They charge hundreds of dollars for the labour to install the compressor...if even available with a short lead time. Thanks again for your video!!
Thanks for watching!
Our fridge was so loud and the tech said he could not find anything wrong with it! We could tell that a fan was rubbing on something and if you would open the freezer you could see the fan stop and so would the noise. I tried this and a lot of water went into the drip pan in the back. For now it seems quiet so we will see what happens throughout the day.
Thanks for the info!
It seems like you have an excessive ice accumulation by the evaporator fan. This could be a one-time deal (if the door wasn't closed tightly, you put hot soup in the fridge, etc...), or become a reoccurring problem (if the defrost sensor has gone bad, broken air-seal, etc..). I'd run another defrost cycle (Test #3), to make sure all extra ice has been melted. And if the problem comes back in 2-4 weeks, call a technician, but not the same one.
Do-it-yourselfer's, no disrespect to the uploader as he didn't create LG's fault codes, but you can ignore this one folks. Of LG's 8 codes, 6 of them list the PCB as a likely problem. Friends, if you took the 20 main problems we experience with refrigerators, odds are huge it's one of the first 19 and #20 is the PCB. As someone who has repaired everything with a PCB short of the space shuttle for decades, 95% of the time it's not the PCB . I had an LG tech out here who told me I needed a new PCB ($500 +) to repair my ice crush function, the part was $9, labor 15 min and I've had 2 other repairs the techs said "replace the panel" and the fix was never $20.
Tommy Daly so what do you suggest when the refrigerator and the freezer are not cooling but everything else seems to be working.
Can you offer any advice? The evaporator fan works when I conduct the first test. But after completing all three tests, the compressor and compressor fan come on but the evaporator fan does not. what' s up?
So just replace the board?
Thank you very match
Thank you so much for the video. You saved me a huge repair bill. God bless you.
Thanks for this! Your video helped me figure out that the fans aren't blowing apparently. So the main board might be a goner. LG has been notified (fussed out) and they have a R.O started now.
During the Test Mode, all fans should blow air... but in some refrigerator models, you also need to activate the door switch for the fan to run after opening the door.
Hope your model doesn't require it.
@@Your-Self it's likely the main board that's gone wrong. When I hit the reset button once, the front panel lights up entirely and the freezer starts making cold air (non for the refrigerator) it runs for about 5min then stops and exits that mode.
I'm not sure what's going on here but it's weird that the fan won't power on until the reset procedure is activated.
My fridge just died yesterday and thanks for the info so that we know not to buy LG crap next time.
Yeah I got stuck with one too. I got it at a restore for 500 bucks. Hopefully its not anything major but having it 2 1/2 weeks lets e know to steer clear of this brand
They can fool me once....never again. Never going to consider any LG product. This brand will not last the test of time. People will eventually get wise to the garbage they try to pass off on the consumer.
@David Pumpkini Samsung is just as bad. They had a similar class action lawsuit
@David Pumpkini our compressor died a few months back and im not made of money so we haven't replaced it yet so I can't offer you any advice other than to stay away from LG. Fridge is only 3 years old
@David Pumpkini You may want to read your warranty packet more closely there mr pumpkini. Everyone else....dont get your advice from a pumpkin
It's posts like yours, that make y-tube invaluable. Many thanks.
Glad it helped!
@@Your-Self yes thank you! Great video
Thank you so much for sharing this great video helping me fixing this FANCY LG product!👍
Glad it helped
Thank you!! You were very easy to follow! Much appreciated!!
Great to hear!
Thank you! For now at least, you saved me a huge repair bill.
Good to hear it, and thanks for watching!
I have a LG inverter 3 door and is building ice where the coils are idk what it could be would the reset works on this fridge pls help
@Manuel Jaramillo what coils are you referring to, the freezer, fridge, or condenser next to the compressor? Please start a new thread with your model number. (I don't always get replies on old messages)
@@Your-Self is the one inside fridge behind fridge wall panel is building ice
@Manuel Jaramillo try to turn OFF and defrost your refrigerator for about 24 hours with open doors. If the ice comes back, you'll need to call a tech to look for a Defrost, or a Drain problem.
Having same issue as others. Works perfect in test mode 1. When in regular operation with magnet trick, the fan behind the air filter is spinning but no air is blowing out of the vent that lead to the door ice maker. I'm not sure where the freezer door sensor is though.
Anyone solve this?
My bottom freezer, the door switch is just inside freezer opening upper surface, middle. Can only see it from below
I found this video extremely helpful. Super simple and effective. It did not solve my problem though. Light M201 in the Inverter section is flashing red 3 times and my fridge is not cooling which leads me to believe that the inverter is busted.
If you have a multimeter, check the compressor as in this video th-cam.com/video/zYIC7LMkKak/w-d-xo.html
Lg says it's the most common issue with 3 blinks. Also, make sure all wires are sitting well. Unplug and plug them back in.
I did the first test then the inside blower ran again. thank you for this video, save ourselves $250 just for a technician to visit or $650 for labor to change the compressor.
Thanks for watching!
God bless you! You saved me so much money!
Glad it was helpful, and thanks for watching!
Me too bro
Hey really informative video, i did the diagnostic test and i did feel the airflow, so if the test mode works but airflow doesn't come on in regular mode, does it mean compressor is ok but something else in sealed system isn't ?
In some refrigerator models when you open the door the fan automatically stops blowing air. You'll have to activate the door switch and hold it for about a minute, and the fan should start blowing air again. If the air is warm, it's probably because of a bad (inefficient) compressor. Very common for LG Linear compressors. LG replaces those compressors for free for the first 5 years.
@@Your-Self hey thanks, in the test mode i opened the door yet could feel airflow in both fridge and freezer, in regular mode i dont feel it, i dont have door switch i have door in door so i can technically still open and should feel air but i dont, what should i check next?
Every refrigerator has a door switch to turn lights out when you close it. Yours is probably the invisible Reed Switch activated by a magnet as on this video: th-cam.com/video/ipwOerjFITg/w-d-xo.html
If the blowing air is warm, it's probably the Sealed System issue (compressor most likely). If the air is slightly cold, hopefully, a Defrost Problem, but could also be the beginning of the Sealed System problem. To verify it, you'll need to remove everything from the freezer and look at the Evaporator Coil frost pattern. Thick layers of frost and ice, means Defrost problem. No frost at all, or very little on ONE SIDE ONLY, means Sealed System problem. If you activate the door switch, but the fan is still not blowing air, that's a rare problem... possibly the main PCB.
Did you ever figure out the problem? I can also feel cold air blowing during the test but not during normal operation.
@@Your-Self I’ve run through the tests - thank you for this tutorial! - and the Error Code light isn’t lighting. The refrigerator is lukewarm but the freezer works fine. I’ve cleaned the disgusting fluid that had pooled in the evaporator tray (on the bottom right, beneath the fridge’s rear bottom panel), but I’m not sure if that might have been related. I also haven’t figured out how to clean the drainage tray that’s visible through the plastic vents at the back interior bottom of the refrigerator section.
Did this. All seems well. Short and informative thank you.
Glad it was helpful!
This video save me from buying another refrigerator, thank you so much!!!
Good to hear it!
I would like to thank you very much for this video. We have kenmore elite french door model 74043 , built in 2016. It has all LG stuff in it. We ran the diagnostic test and everything was working fine, even the air was cold and yet refrigerator is not going lower than 50 degrees. freezer is working fine. We opened up every part of the refrigerator and freezer to make sure there was no ice buildup but everything is squeaky clean from inside out. going nuts here. Please help us.
When you say the freezer temperature is "fine," can you verify that it's around 0°F with a separate thermometer?
When the fresh-food compartment is not going lower than 50°F, does the compressor continue to run (trying to cool lower), or it's resting?
What is the complete model number?
Defrost may not be working or the drain is plugged allowing ice to build up.
Ever get a fix, having a similar issue.
@@claimed4alldid you fix it?
Thank you for the helpful video. I tried the test on my LG fridge (my PCB is mounted on top) but didn't seem to produce any errors. After a power outage the freezer is blowing air that is about 55 degrees F. Won't get colder even though compressor stays on. Any ideas what might cause that? Oh I can also hear a slight buzzing coming from the PCB, not sure if that is normal.
A power outage may corrupt the PCB, so it's best to plug the fridge and all your electronics into the surge protectors. After running this test, the PCB may get reset and come back to full life within 24 hours, or may not.
Make sure the condenser coils, next to the compressor, is not full of dust and hair... clean with a brush and vacuum if needed.
Next, I'd check the evaporator coils behind the back wall inside the freezer. If it's covered in a thick layer of ice and frost, you may have a Defrost Problem.
@@Your-Self I have the same fridge with PCB board top and has the same issue with power outage. Ran the reset test and clean the condenser coils, no luck. Should I turn off the refrigerator for 24hr or leave it on?
@@namlam9956 why isn't @yourSelf replying? I have the same issue too, after power outage my fridge/freezer was not cooling, tried reset got no errors and no cold. the freezer and fridge ran for a bit then stops.
Omg! Thank you for this!!!! This test saved my fringe!
Glad it helped!
I'm learning From your video.
Thanks 👍
Good to hear it, and thanks for watching!
following 2nd check, 22 22 appeared on my display panel. What would this mean? thank you so much!
The 22 22 is just a notification that you are on a second Test.
The 33 33 is the third Test.
@@Your-Self after second test it just goes back to normal
@Edward Papkow some models have only 2 Tests... all fans run and then Defrost.
I thought he said error 22 means you have to order something for 20-30 bucks
LG fridge $1495 bought feb 2018, quit working I unplugged and cleaned compressor and fan area. Plugged back in and still no heat. LG was great at giving me a phone number for a service center which I will have to pay parts and labour. Thanks to LG we are now using a 25 yo Frigidaire we were given for free. Our next fridge will not be LG
If your fridge quit working because of a bad compressor, LG should fix it absolutely free (if you have the purchasing receipt)
We contacted LG and they sent out competent tech to replace compressor for free. We did have to buy a mini fridge since it was a week before he would show up.
Thank you so much. The model you used in the video is the exact same model that I have.
Glad I could help
@@Your-Self unfortunately it did not solve my issue, still good knowledge still had a technician come out under warranty replace the compressor and dryer LG having a problem with these specific things
Your video has been a BIG joy in helping me to troubleshoot the problems with my Kenmore/LG refrigerator. I went through the test modes (everything checked out ok) but the error light on my PCB is not blinking any error codes at all. Will this light activate when I push the reset button, or should it already be blinking if there's an error? My refrigeration is not cooling but everything seems to be working ok.
Your situation sounds like a typical LG Linear compressor problem - running but not cooling.
If you can feel the air movement inside the freezer and the fridge, but it's not cold, the compressor is probably bad. And unfortunately, there is no error code for this particular (most common) issue.
Thank you so much - I went through this sequence yesterday and today the fridge is working fine and I am so grateful to you. My question is, this having happened, what could cause it to STOP working and does this mean that the compressor is on its way out? When I did the part of the test where the LED light would indicate problems, there was no blinking. But I'm worried about putting a bunch of food in there again if it is likely to happen again soon.....
Nowadays refrigerators are run by electronics and the software. Just like a typical computer or your phone, sometimes it locks up and needs resetting. This can happen for no reason at all, the power outage, or an electrostatic shock if you finally decided to remove that protective plastic cover from the door ;) So nobody knows if it happens again, but I'm glad your fridge works now!
Hi there. Amazing video. I tried this however during the test I can feel the cool air coming through the vents but it doesn’t blow any air during normal operation. Fridge randomly started to not cool. Both the freezer and the upper compartment isn’t cooling. During the test there is cold air blowing in the compartments but once test is done there is no airflow. Any fix ?
Try to narrow down the problem.
1. Does the compressor regularly turn itself ON and run, but you don't feel any air inside the refrigerator?
2. Or the compressor never runs during normal operation, but works during the test mode?
Keep in mind that in some models when you open the door, the fan will automatically stop blowing air, so you need to activate the door switch and hold it for a minute for a fan start again.
YourSelf thank you for your reply. Compressor is on full time but the cooling is very low. It’s still cooling but no where near the normal cooling temperature. I don’t feel any air blowing into the compartments at all
You didn't mention if you activated the door switch for about a minute while checking the airflow... that's important.
What is your refrigerator model number?
Having the exact same problem, my model is lmxs30776s. Test mode fan blow cool air, when test mode is done the compressor runs for about 3 or so minutes then stop then run again and repeat that... freezer someone cool fresh food compartment is hot. The fan next to the compressor continue to run. The compressor was replaced by a certified technician and that’s when the 6 flashes started. Replaced the PCB board which I don’t think was the problem now. Still no good. Refrigerator $3000 plus, compressor $500 plus labor, PCB board $230. I have a very expensive hot box taking up space in my kitchen
@Michael Maxwell nice and complicated model with a dual evaporator. Maybe the certified tech didn't know how to work on this model. Probably need to reinstall the compressor and refill the sealed system properly. If it was replaced by a new "Universal" compressor, the main PCB needs to be reprogrammed with a special LG software jig to run properly.
Thank you! Very helpful video! Life saver :)
Glad it helped!
Love how this guy teaches.
Thanks for watching!
I did the test, it looks like everything was working the fans inside the freezer and fridge were working fine for around 5 minutes but then they stopped.. so what could it be...
Any luck
@@shanebudiac6481 no
Same for me. Did the tests and everything worked - fans blew, compressor working and I actually felt cold air. Finish test and fans / compressor stop working.
Anybody figure this out? Everything seems to be working in the back but nothing in the front.
Same... But it won't cool.
I have a LG LMXS27626D /01 French door refrigerator that stopped cooling. It’s about 3.5 years old. I’ve run through some troubleshooting based on your videos. Thanks, they are helpful!
My compressor seems to be running, it’s warm and it hums/vibrates. I used my multimeter to check the windings, and all seem to have checked out. I get about 8ohms across 2 pins and 0 across the other 2 paths. The compressor fan operates fine. There is no LED that I can see on the PCB when I do the test/reset operation or indications of error codes... The evaporator fan seems to be working since I can run the reset test and there is air movement from inside the fridge, just not cold air. The other test I did was with an infrared thermometer to check heat output on the various components. I’m not seeing an increase in temperature across the condenser coils. So what does all this mean? I’m guessing low refrigerant?? Or is this still a bad compressor? Or, something else...
I contacted LG and they’re sending out a tech in like 3 weeks… That’s too long. What do I do?
It sounds like a typical LG Linear compressor problem... running but not cooling.
They should replace the compressor absolutely free (parts & labor) for the first 5 years, but you may have to "fight" for it.
Meanwhile, if you don't have a spare fridge, maybe get a small one until they fix yours.
@@Your-Self Thanks for the speedy reply! So are they going to come out and replace the compressor with another unit with the exact same problem and in about 3 years I'll be faced with the same problem? Or, did LG do something to actually fix the problem with their linear compressors?
According to LG, they have improved the Linear compressor about a year ago, and it's called a "Universal compressor" that fits most models. But there is no track record to prove that it's any better than the old one, so only time will tell.
My LFX28978ST from 2011 have linear compressor replaced in 2015 and its bad again not even 7 years full (why I am here). First time they charge me for labor which came out $200-something and this time since no warranty, I am just gonna go with local repair shop. Cannot believe how bad those compressors are as old cheap fridge can go 20 years
Thanks for the video. We have a LG LMXS30776S/04 and it’s 3 yr and 1 month old now. Ran the smart diagnostic and no errors were found. Performed the test modes per your video and for test 1 the condenser fan turns on and the compressor is also slightly vibrating. The fridge and freezer fans are on and the air is blowing cold. On the second stage of the testing mode the condenser fan and compressor is still on however only the freezer fan is on. There is also no light flashing on the pcb board during the tests but the lights on the front panel does show “22” - “22”.
I also tested the relay and compressor prongs and got around 8.5-9 ohms on one prong set and 0 for the other 2 prong set. Based on your comments it seems like I have a compressor issue but not entirely sure. Thanks again.
Based on your description, everything works as it is supposed to.
Check if the fan inside the fridge blows cold air during "normal mode" while the compressor is running (you'll need to activate a door-switch with a magnet, so the light turns off).
If the fan works, maybe the air is not cold enough. This could be due to a defrost problem, or most likely, the compressor going bad.
Call LG directly if you have the receipt, and they should replace the compressor absolutely free.
Great tutorial. Thanks much
Glad you enjoyed it!
If you're LG has a linear compressor....it's bad, or is going to fail. There's a class action lawsuit against LG because of this.Huge problem for LG.
Hello - thank you for this heads up. I was 'this' close to going out and getting an LG side by side with the linear compressor (even though it says 10 year warranty on compressor). What exactly is the issue with it though and purported failure mode? Thanks.
DO NOT BUY LG REFRIGERATORS. MINE BROKE DOWN THREE TIMES AND THEY HAVE DONE ZERO TO HELP ME.
They are nice and roomy, have good features but there is something wrong with them just like the washers.
I think our last one was damaged or something during manufacturing so after 5 repairs we got a new one and it got loud after a year and the tech that came out under warranty said he could not find anything wrong. We even did a video for him with the sound and it went away when you opened the door, you can tell a fan is rubbing on something
maybe ice build up in the freezer. I hope this fixes ours as I am about to open the freezer up to see if there is ice rubbing on the fan blade.
I AGREE.
Appliances should last 20 years like they used too.
i agree
I wonder how much it's down to you. Most companies aren't that bad these days.
Amen!!! Same here!
Thanks this video was very good and easy to understand plus great information
Glad it was helpful!
I think you just helped me fix my fridge
Step 1: Don’t buy an LG fridge
😂
That was step 2 for me after step 1: buy an LG fridge and understand it’s crap
Perfect! It fixed my fridge
Very very helpful. Thank you so much. ❤
Glad it helped.
Very clear instructions
Thank you for sharing your knowledge. I bought an LG 3 years ago and it stopped cooling. We cleaned vent and did a reset but it still does not cool. Was told to hold freezer temp and ice button for 3 sec and got a code 88 88
For the 3-year-old refrigerator, it's worth calling LG directly so they can check the compressor. It's very common for LG linear compressor to fail early. If it is in fact the problem, they may replace the compressor for free.
Great video. Bought my refrigerator June 2021. Now the compressor and fan suddenly not working. Did the test and only the bottom freezer fan working. Light indicator blinks 3 times. I guess the motherboard is toast.
We purchased a used LG refrigerator almost 10 years ago and we are just replacing it now.
Thank you so much for helping us out
Happy to help
Thanks! You're a life saver!
Happy to help!
Very clear and steady
Very Informative. Thanks
Thanks for watching!
this didn't help very much but, it helped figure more about my fridge. THANKS
Thanks for watching!
hie please i have a defy f600lm it completely shut down then i tried to test the compressor on its own its working should i do also this reset is going to work
This did the trick however my display in front is still off for the ice and water compartment. Thank You!
Thank you for the informative video. Everything went well and Unfortunately the fridge still does not cool. Will have to call technician.
If your fridge is under 5 years old, call LG directly... they may replace the Linear compressor for free.
Hi,
Thanks for a very useful and nice video.
I have a lg gr-f802hlhu model refrigerator. I just have an annoying buzzing sound from the compressor.
Services in Turkey do not know even one of the things you are talking about. Therefore, unfortunately, there is no professional service provider to tell my problem.
You can try placing your hand on the compressor and some copper pipes around (wear a rubber glove for safety). If the sound stops, that's a vibration you may be able to fix. If not, the sound may be coming from the inside of the compressor, and there is nothing that can be done. If there is a fan next to the compressor, maybe the sound is coming from there?
Thank you very much for the video I did the first step and I heard the bips after when I did the second step I didn’t heard nothing and there is no cold air could you please answer me
Thanks for your videos. 🇪🇨🇪🇨🇪🇨
Thanks for watching!
Hi, thank you for the video it really helped. Question, My LG stopped producing ice in the bottom freezer. I did the diagnostic test like you demonstrated in the video. I don't have the LED light, however on the front panel it was showing me a 33 33 code. I looked it up and it said it was the freezer door switch. I replaced it, redid the test and it still shows that same code. Any ideas what it could be?
I want to thank you for the video, even though I do not know if it fixed anything, I had fun running through the test. I didn't get any LED blinking and my compressor and the fan are running. Compressor sounds fairly quiet but didn't hear a relay clicking. It gets cool but my freezer section isn't getting all the way down to 0, and probably not even 15 because the icemaker isn't cycling anymore. It almost makes ice but it's not solid, just not quite there. Very frustrating problem. I am going to give it a day and then possibly see how much LG will charge for the labor. If anyone has more info in buying a labor warranty from LG I would appreciate it.
It sounds like the compressor is going bad, or there is a refrigerant leak from the System.
How old is your fridge? If it's under 5 years, LG may fix it absolutely free. Otherwise, they may charge about $400 for the labor.
@@Your-Self Unfortunately, mine is 8 yrs old (AUG 2013). Actually after giving it a day it is working better, much better actually. I didn't mention that I cleaned the coils in the bottom rear real well, the coils themselves weren't too bad but the vents in the panel were pretty clogged. Now need to monitor for a few days or weeks!
@@harryrobinson713 Hi Harry...what "vents in the panel" are you referring to? My coils look pretty good, actually, but I did vacuum a tuft of cat fur out from under the fridge. I have a Kenmore Elite (essentially an LG) and have been plagued with the potential compressor issue. It runs and sounds fine but I don't know enough to know whether I have a leak in the system or a clogged line or whatever. It's near impossible to find a tech willing to even look at this. And trying to get a hold of Sears requires waiting until November. I'd hate to toss this...it seems such a damn shame and a waste and goes against my always strong desire to leave no stone unturned until I have a fix. Thanks for reading...
@@trafficcone I just meant basically that whole back aluminum panel was pretty much covered with dust, that kind of thick greasy kind you get in the kitchen unfortunately lol. So the vents or louvers were pretty clogged and probably wasn't allowing much air flow anymore. I should do this every six months probably
Thanks for this tips. But what does it mean exactly if I have 3 red flashing? Do i need to change the all pcb has you said earlier or is it an "easyer" fix? Thanks again
please can your help me ini have may refregerator lg not cooling , in the first tim when i applied a reset button my refregerator turn on and work properly for 2 days and it's turning off and the problem return it's not cooling i rested it in the second time but it doesn't work any hot air inside came from the ventilator please could you help me to repair it !
Thankyou so much for this information. It saved me needing to call a technician
Glad it helped, and thanks for watching!
Thank you so much.⚘🙏🏽
Thanks for watching!
Thanks man... my LG shows error code ff and both freezer and fridge aren't cool properly the fridge fan is out but I'm not sure how to check the freezer fan... I think it's a magnetic switch or something... thanks again for the test button information 👀👍
FF - is the Freezer Fan error code. The fan may be damaged or stuck in ice due to insufficient defrost cycle. If you can, disassemble the freezer to verify ice buildup around the fan.
The freezer fan has probably iced up. The easiest way to fix that is remove all food from the freezer and refrigerator section, unplug the unit and let it defrost for about 24 hours.
You may have to repeat this every six months. I've had this problem for close to 5 years now and LG says my refrigerator is fine.
Hello thanks for info all the fans works during test mode but don’t seam to work now
I have the LG French Door model I follow all your steps and everything checks out. The evaporator fan is blowing I can feel it in the vents after a minute or two I can’t feel it thru the vents but when I check the fan it’s still blowing what could be my issue?
Great video. Any ideas why the refrigeration portion would randomly shut off, but freezer keeps working? It conveniently happens when we are away overnight. We come back, refrigerator is warm, but freezer is fine. Plus my light is out on my refrigerator portion, I've swapped the harness, but it's still out, which leads me to the PCB. I'm likely going to swap the PCB and see what happens. Just thought I'd get your two cents before I do.
A lot depends on your refrigerator model number. Do you have a dual evaporator, a dumper door, or just a hole between the freezer and the refrigerator section? Is refrigerator light always out, or when it stops cooling? Did you replace the harness with a new bulb, or just a harness?
Thank you for the video. My freezer begins working properly, but randomly doesn’t get cold enough to freeze for about 2 days, then freezes again. This process has happened about 4 times in a month. What do you think it could be?
Intermittent issues like this are difficult to diagnose, especially over messaging. It could be the fan occasionally not working, sticking relay on the PCB, partial/moving restriction inside the sealed system... etc, so it's probably best to call a tech to look at it. Sorry that I can't be more helpful. PS when it's freezing well, measure the temperature inside the freezer for the technician to know, and if it's warmer than 5°F, it's not good freezing.
hi what was your issue , mine is doing the same thing , was once a year at xmas time , now its out of warranty its doing it monthly
Thanks for that vid. Well explained.
I have a deep fridge from haier company. There is a connection from the controller named by PMW with two cables. Wich is connected to the inverter board. I think it gives the command. I have the problem that the compressor not runs by every command.
Do you have experiance with controllers and pulse width modulation commands?
The controller sends a small DC voltage (PWM) of around 2-3 volts to the inverter to run the compressor.
But most of the time the inverter burns out so the compressor can't run. Inspect the inverter board for burnt marks or inflated capacitors.
doood this information was great. thanks for the help;)
Glad it helped!
My fridge door was left open a bit when we went out unknowingly, came home to it barely cool so I closed door and figure it would catch itself but woke to it being warm so I unplugged for an hour but it runs for about a minute then stop so I try the test and the comp and fan runs but no cooling,then stop after a few minutes,seems like a leak to me or is it faulty linear compressor?
I purchased LG side by side door refrigerator, when i connect to wifi and doing smart analysis it is showing there are high humidity level at the installation location. No air flow is coming from vents like when AC is on and when we keep our hand we feel air is coming out.what may be the reason. Please reply
I jst dd bt how long does it take for the temparature to change to cool mode or freeze
Thanks for all the helpful videos.
One question... after doing tests and resets, the compressor and fan operate fine, but no cooling. No LED indicator. Lights still on inside fridge also.
If the compressor and all fans are running, and you can feel the air movement inside the refrigerator but it's not cold, that's a pretty bad sign of a major Sealed System problem. If your LG refrigerator is under 5 years old and you have the purchasing receipt, LG may fix it for free.
@@Your-Self Thank you. That's what I assumed. Much appreciated for your help.
@@Your-Self what do I need to do since I have a receipt from Sept 2017 pertaining the refrigerator purchase? I think my seal needs to be replaced.
@@Your-Self How can I be sure yhat its the seal?
So run through the tests and no codes show. When in normal operation I get water puddle that freezes inside the floor of the freezer compartment. Heater element ohms test shows 32.1 and defrost control sensor tests good. There is no obstruction from sheet metal defrost catch tray inside freezer compartment to and thru the tube to the evaporation tray by the compressor. Is it possible the heater can pass the test but be getting old and not providing enough heat to do a complete defrost?
Thanks much for the vid very helpful
The heater either works or doesn't. Most incomplete defrost cycles are due to the defrost control sensor (thermistor or thermostat, depending on your model) going bad, or attached in the wrong location. And can you visually confirm that the ice/frost not defrosting completely?
What is an actual problem with your refrigerator... not cooling or a puddle of water on the freezer floor?
If you are absolutely sure that the defrost water drains-out well, the icemaker or the water dispenser could cause a water-puddle on the floor.
Thank you very much
Thanks for watching!
When I run the diagnostics check, I can get the first 2 tests to run. After pushing the test button the third time, nothing happens. No audible beeps or action happens. My compressor, fan, and evaporator fan all will work. The fridge became inoperable after a power outage. There is also no flashing light on the control panel that indicates any problem. Would you say that the board is probably bad?
How do I fix the reset button the blue part has like gone in and won't budge..the part of setting cold, cooler.. coldest kindly assist if you can
Lifesaver!!!
Thank you this is very informative. does the main pcb board control the ice maker cycles or just supply power to the ice maker. thank you (my fridge is a few yrs old and the ice maker will not cycle, i have tried turning power off/on but i only see the green led on the ice maker...no movement. i have water to the ice maker and the temp is cold enough)
Every model is different, but the PCB probably checks for the right temperature around the ice maker and then sends the power to it.
Look for a test button below the ice maker or a pinhole on the side. Slide a paper clip into the hole, and hold it for 3 seconds for a cycle to begin. Or hold the test button for the same 3 seconds. If the ice maker is not rotating, it's probably bad.
@@Your-Self Thanks for the quick reply. I turned the ice maker on/off several times waiting 10 minutes. And also pulled the 120v pwer from the fridge. And Praise the Lord after a couple of hours it started working.
Thank you very much. Few TH-camrs are so thorough in spelling out the steps. I'm still left with a mystery though: I pressed the button one time (never any LED flashes), and my refrigerator started blowing again. I may never know why it was tripped. Any ideas? (I won't know for some hours whether it cools, but the compressor and all fans are blowing).
LG linear compressors cool very slowly. So give it a whole day to work its magic.
And if it's still warm, there could be a Sealed System (expensive) issue. If your refrigerator is under 5 years old, LG may replace the compressor for free.
Thank you!
You bet!
Hi ur video been great but I still have one problem that after I finish the test the fan stops after few minutes then I redo the test same happens so can u please help me to find the problem or the solution
Thanks
👍👍👍!!! Thank you, sir!!
You bet!
Hiya so i got lfxs24623s/00 I think same as your video, when I do test 1 & 2 top fridge n bottom freezer is pushing out cool air test 3 nothing no cracking. Once the test is done I get barely any air thru wants. My freezer does not push any air n top minimal air. The ice maker does not make any ice nor does it work obviously. The compressor was super hot earlier I clean out coils beside fan bc it was dirty, didnt make any difference other than keeping compresser cooler while running. Any clue ?
Hi, I have a Kenmore Elite and my fridge and freezer fans stopped working causing them temps to raise to room temp. I took off the lower panel on the back of the refrigerator and observed the condenser had a light hum to it and the fan next to the condenser was on.
I then TH-cam some videos and came across yours. I followed your directions and removed the motherboard panel and pushed the test button. The internal fans began to work in test mode, however once the system went back into normal mode the internal fans stopped. As you had recommended to others, I held the door button to trick the system into thinking the doors were shut but the fans were still not on.
From the comment I see on here, it seems to be a common issue. I contacted Sears and they said since it was purchased in Sept 2018 that the warranty expired except for the condenser, which is a 10 yr warranty so if it’s the condenser then at least it’s covered. I am scheduled out with Sears a couple of weeks and hoping that I am able to fix it sooner than that. Hoping folks that have had the same issue chime in to what the fix was for them. Thanks for any and all input for this problem!
During the Test Mode - if the fans are blowing warm air, the compressor is probably bad.
If the air is cold, the problem could be with a temperature sensor, door switch, motherboard... to figure that out, requires a lot of testing.
@@Your-Self thank you for your input! I would say the air isn’t warm or cold but more room temperature.
Yep, when I said warm, I meant room temperature. So it sounds like the compressor is bad, just idling.
@@Your-Self thank you so much for the direction! I will update after the repair by Sears.
Sir in split unit lg.what is the ohms of coil thermistor and tube sensor from evaporator..thank a lot sir
