What you are calling a start relay on your linier compressor, looks like a " Klixon " thermal protector. Placed in the terminal box to measure compressor temperature, and disrupt the power to the compressor in an over temperature compressor. Your testing of the compressor winding is accomplished with the " Ohmmeter " function of your DVOM or VOM, depending upon what instrument you are using. Tim

Thanks for your efforts, i'm old school since 1994 I really hate what their doing with pcb controls keep it simple is the best, all my customers complain "its only 2 years old and it not working" LOL I tell them your relying on 3 thousand components just to keep your food cold, in the long run it's worst for the environment than the old thermostat controls because energy used for early recycling and remanufacturing.

[@Joeaboul]

Hi, Michael, I have LG LMX2596ST refrigerator which I bought 9-10 years ago. It does not cool on both compartments, so I checked the condenser which is good, I changed the evaporator coil assembly (New); I changed the LG 6500JB2002X Temperature Sensor, Single Unit; I also changed the thermistor assembly, but it still is not working. what do you thing I should do next? I bought refrigerant to put into it but I am a bit hesitant so would want to explore other checking points.

[@annettesurfer]

Our 2013 LG LFX33975 french-door refrigerator was purchased 1/2014 and cooling has always been warmer than whatever it's set for in both the fridge and freezer. I opted for the 3 year LG Premium Care extended warranty for a little over $300 and after that LG only offered a 2 year plan and the price increased to about $500, but we bought it anyway. Good thing too since shortly after re-enrolling, everything in the freezer suddenly melted in April 2017. After almost 2 weeks, a tech finally arrived and said it needed a compressor, a drier, and condenser. He ordered the parts and left. The parts arrived and a week later a different tech arrived and said it only needed a circuit board so he took the parts with him. I don’t recall if we had to wait for the board, but I think he had one. After that, the fridge was the coldest it had ever been at 38 degrees. Then in August 2018 it wouldn’t get any colder than 50 degrees so after another 2 weeks a tech came out and said something about a large plastic center section being updated so again the part was ordered and eventually installed. That lowered the temp to 40 which is what it’s been since the day I plugged it in except for the time mentioned above where it hit 38. Anyway, one day everything melted in the freezer again and the fridge seemed stuck at 50 so I again called for service but by the time a tech came out, the fridge seemed to be back to normal so the tech didn’t find a problem. I had a repeat of that in June 2019 but this time I was told I’d have to pay for the service call if no problem was found. Like the other time, the fridge normalized by the time they called in mid-July to schedule the service call so I just cancelled. Since the extended warranty seemed to have been a waste of money, and the coverage offered was reduced to yearly while increasing the price, I let the coverage go. Well it’s August 2022 and for the past few weeks we’ve been noticing the milk has been starting to go bad way before the expiration dates, the assumption being the store may not have been refrigerating ‘em promptly after arrival, but then a few days later we noticed water on the floor. The fridge had a 50 degree temp and the freezer was about 20 degrees. A Google search said it had a blocked drain line so I took the large plastic center section out and I didn’t see any ice but the tray was full of very cold water. I left the fridge unplugged for a day but the drain was still plugged so I tried poking some thin plastic tubing from an air shock into the tube but kept hitting an obstruction so I tried going upward as well from the back of the fridge, same obstruction. While contemplating my next move, I found the water had drained and the plastic tubing no longer found any obstructions. After a day of normalizing the fridge, the lowest it would go is 46 degrees and 11 for the freezer so I looked at the board, nothing on the LED. I pressed the test button once and heard a single beep 3x. Both the upper and lower fans in that large plastic panel in the fridge started up and the front display was fully lighted. The compressor and the fan next to it were running as well but the test cycle lasted about 5 minutes before shutting everything off except the interior lights and the front panel resumed normal function like when a door is closed. At that point the fridge was 50 degrees and the freezer was 29 degrees. A few minutes later, the compressor started again. At that point the compressor felt hotter than usual. I should say the compressor is also quieter than it was when new. I pressed the test button 2x, heard a double beep 3x, the front displayed 22 and 22, and everything started running again. Again everything shut down after about 5 minutes and the display returned to normal. Almost another 5 minutes passed and then I could hear the two fans in the fridge start, a minute or two later the fan next to the compressor started and finally the compressor again. Pressing the test button 3x didn’t reset the fridge as expected but just shut down all the moving components and the front displayed 33 and 33. After 5 minutes I heard a click but everything remained dead silent. Another 5 minutes passed before the fans inside started and then another 5 minutes passed before the compressor started again. So the total time to resume was 15 minutes after the test button was pressed 3x. I’m guessing that last test activated the thaw cycle because after the 10 minute mark where the fans inside started, I saw the puddle under the drain tube move and I heard erratic type sounds like water sizzling in a hot pan. I noticed the fridge said it had “Smart Diagnosis” so I found the procedure in the manual and called LG. I had to ask for it and was then transferred to a tech that didn’t speak English very well. I was instructed to lock the panel and press some buttons while holding the phone up to the speaker in the top right hinge until the series of squeals stopped and then the guy asked for the temps before concluding it needed a compressor. Since the compressor has 2 years left on the 10 year warranty, he texted a couple places to call but labor would be on me. The first place was the place that has been here many times but they said they no longer service LG. The next place said $800 if the compressor was all that was needed. I called LG again for more options and they texted 3 more. The first said $500-700 but they were 60 miles away and didn’t service my area. The next one was just a guy's name and when called, it said “call rejected.” The last one was 250 miles away so obviously that would be a waste of time. It’s a shame this model wasn't included in the class action lawsuit that was settled. The date of manufacturer and history of problems matched perfectly. I looked up how to replace a compressor and honestly it doesn’t look that bad since I’ve been doing A/C work on vehicles for over 40 years and it’s only R-134a so I have a vacuum pump to evacuate and a manifold set to charge it but then I read about the board will need updating so I guess that’s out. I’m beginning to think the problem may not even be a compressor issue so I thought I’d seek opinions before having to go into debt for another refrigerator. Consumer Reports says for 34” and wider, the top 4 models are LG, for 31-33 inch, the top 2 are LG, and for 30 inch and narrower, the top 2 are again LG. Maybe the problems were fixed but I guess time will tell. ($4500 for #1) Samsung rated poorly with 45 fridges rated better, mostly LG, but Samsung has failed me on all my other appliances, which seems to align with CR, so I’d rather find the problem with this LFX33975 if possible. Any thoughts? Edit: I installed a $5 (+$2.99 for same day delivery) BPV31 piercing valve on the low side to check the pressure but never realized how terrible my R134a manifold gauges are when reading low PSI. I even took a picture so I could enlarge it but it didn’t help. All I know is when running, the needle barely moved from 0 and about hit a high of 28 PSI after sitting off for a while. I gambled with an evacuation, put a vacuum on it for an hour and then let it sit for another hour with the vacuum off. The vacuum maintained so I slowly allowed some R134a back in while still unplugged and at some point I let the compressor slowly take it in while frequently noting the PSI pressure. The moment the high side started feeling warm, I unplugged it to let the system equalize. The final recharge ended up being a little less than 40 PSI and temps in the fridge went from 50F to 39F, and the freezer went from 31F to 3F so I guess that’s progress for not knowing what I’m doing. That’s the coldest the freezer has ever been and the fridge part is about the same or lower than we’ve experienced since we bought this new in 2014. But I don’t trust it so we bought another French door refrigerator from Best Buy on the zero-interest installment plan because they service what they sell. I chose a model from the small offering on the LG site hoping for a current model with all the problems corrected as Consumer Reports and many sites contend. Plus LG has a sale of $700 off and BB has it for a penny cheaper. Of course I had to add the $599.99 5 year standard Geek Squad protection for peace of mind. Nothing fancy like the window in the door for a grand more model. The irony is this fridge was one of several models offering a BB promotion of a free LG 6.9 Cu Ft top-freezer refrigerator with a value of $714.99 (yeah right) But at least we’d have something to put the food in while waiting for service if this new LG breaks again. Edit again: Cancelled the new fridge since the recharge brought it back to the 38F and 6F it was when new in 2014.

[@robertw1871]

Sounds like you have a small leak in the evaporator, the best way to check is the frost pattern, if you pull the cover in the freezer and only a few on the loops are frosted at the top then it’s either low on refrigerant charge or the compressor is inefficient…. It’s not exactly easy to measure the temperatures, you want the probe very near the thermistor where the machine is measuring it and defrost cycles and opening and closing the doors will affect is greatly as well as exactly how food is loaded, airflow can cause problems with temperatures being off, when the temperature sensor in the fridge is satisfied at the set point it will shut off that doesn’t necessarily mean the temperature will be the same everywhere… I use a thermal camera to verify all the cold and hotspots as a fast check, without that tool you’ll have to wrap a thermocouple with aluminum foil and tape it within an inch or so of the machines sensors and do an average of the numbers to get an accurate temperature measurement… If that’s ok then your problem is airflow, either food is blocking the return path or the fan might be weak, it’s also possible to have ice on the evaporator block airflow. That can also be caused by low refrigerant charge or lack of airflow or a leaking door seal that’s allowing humidity to freeze that’s more than the defrost heater can manage….

[@annettesurfer]

@@robertw1871 Thanks for the input! I believe you’re spot on. I think our problem that prompted the post originated because our 13 year old left the freezer drawer slightly ajar for several hours while he was gaming and couldn’t hear the beeping so I suppose the humidity overload was enough to cause issues but after unclogging the drain, and waiting 24 hours to normalize, the R temp was stuck at a low of 50F and the F temp hit a low of 20F. I’ve read about something in the system that either because of age or an unforeseen chemical reaction, becomes caustic to the components. It did hold a vacuum and after I charged it with about 8-10 oz of a small 12 oz can of R134a, I used a vintage Micro-Tect (209901) electronic leak detector (sniffer) over everything and couldn’t find a leak anywhere. I’m shocked the effort actually worked after the official LG factory rep, told me in broken English that it needed a new compressor. I’m wondering if all those other “defective” refrigerators could’ve been saved by merely installing fresh R134a. For years we’ve been using a pyrex refrigerator thermometer and a Taylor Lithium refrigerator thermometer but opening the door to read them wasn’t ideal so we recently settled on an Acu-rite (00515M) ($35 Amazon) wireless refrigerator thermometer that has two sensors and a programmable alarm that can be set to trigger when a temperature is out of range for longer than five minutes. We don’t have to open a door to read it and along with the current temp, it displays the high and low temps in the past 24 hours. The freezer is currently 8F but in the past 24 hit a low of 3F and a high of 16F, the fridge is 38.5F and in the past 24 hit a low of 36 and a high of 41. Perhaps the LG is running on borrowed time but so far, so good. Thanks again.

[@robertw1871]

@@annettesurfer Can’t say I’ve encountered aging components causing an issue, for the most part they are either functioning or not, functioning out of calibration isn’t something that’s common with thermistors and digital electronics. The vast majority of compressor failures are not able to build any pressure at all, the system stay’s equalized, so no, recharging them would not bring them back… If it’s not maintaining temperature then it’s definitely struggling, I’d think it was either low on charge again, or has build up some non-condensables (air) in the system by pulling it it under vacuum from the low side in the evaporator, it’s either that or the compressor has indeed become inefficient… Unfortunately…. Hope it says working for you, have a good weekend…

Did you ever figure this out, I’m having the same issue.

[@kumarbhatia6566]

@@soccer2live Hi. With some courage, I reached out to LG. If you google, there are class action law suits pending against LG for their compressors. After some stern but diplomatic chats on the phone, they extended a 'fixed rate' service for the unit - whatever it may take to resolve a single fault (important to note this). Told them that the fridge would no longer remain cold. The tech came onsite and was excellent from London, Ontario. He noted this to be a common issue and it was the batch of compressors that they purchased. Personally, I hunted for a unit that was made in South Korea rather than Mexico but still got stung by the faulty compressor. The tech replaced the compressor and this was a few years ago and crossing my fingers, still ice cold. The tech noted that if the plumbing is at fault, toss the fridge. Personally I am sold on LG again since they did fix the fault and I believe I paid around $350 for the repair. Be 100% clear on the fault(s) because they log them into their database. If you deviate the fault afterwards, they will demand a new service call and fee. The tech also updated the firmware on the controller board so best if you follow the LG official tech. I am in Canada and can share the details of our tech who performed the service. Highly recommend this outsourced company but is only practical if LG is paying for the compressor. That is, $350 will not cover the expense of the new compressor + installation fee. If LG still offers this fixed fee service call, suggest that you consider it. The company who serviced our LG from London, Ontario was appliancesrepairservice.ca/ - Kevin Parmar was the tech and is extremely knowledgeable. Highly recommended. He mentioned that the replacement compressors from LG are solid. Not sure how old your unit is but for us, ours died in about 5 years but going from memory here.

Hello. Would you share your case? I have the same situation and I’d like to make sure it’s the compressor before I spend the money. Could it be the capacitor? Thank you

[@kumarbhatia6566]

​@@JoseDiaz-yo6qj Hi. How old is your fridge? I recall following the above video which is excellent but could not resolve the fault. Raised a stink with LG and how our fridge did not cool for the 10 years they claim on the compressor. You can attempt to test with a new run capacitor which DID fix our outside AC unit's fault - just order one through Amazon to test and return if not required. For our fridge, LG offered a single fixed fee repair service to resolve our fault. We did contact local repair firms and each was more expensive than using this LG offer which would be with a new compressor + onsite installation. If the fault is in the plumbing - the fridge is garbage - the onsite tech noted this comment. The LG authorized tech also stated they repair many brands (out of London, Ontario) and that the new LG compressors are solid. Ours is still running strong (was installed at start of covid time so a few years now). The root cause was that LG used some outside firm for the compressors and they did not live up to the quality of 10 year use. Important to note that only the authorized tech has access to the firmware updates which were installed onto our fridge after the new compressor was installed. IMHO, we are a LG family again. Personally bought our fridge after years of research and used an old unit till we were ready. Our fridge is made in South Korea (HQ) rather than Mexico because the quality was not yet known about their factory in Mexico. There are class action lawsuits in motion against LG for their faulty compressors but no idea if and when that will be resolved and with which amounts. Highly recommend to consider the fixed fee service if the unit is out of warranty but be stern about the warranty of the repair which I believe was another year after installation of the new compressor. Hope this helps.

[@CS-gd9nq]

This is a great video, I’ve replaced the board and done so much testing on mine. Was about to trash my fridge until I found this video. I’m so glad I found this it has so much helpful information 💖

[@bwguardian]

@CS-gd9nq so did you fix it with the board? I just checked mine and my compressor is not grounded, but I'm getting a reading of 11.5 instead of the 7.5 he states...not sure what that means. I also don't have the green LED light on the board with the same error 22 22 code, so I'm assuming that means a bad board too.

[@CS-gd9nq]

I did fix the board I had an F-1 code and the fans were still working. Replaced the board from eBay for cheap cleared the code but the fridge still isn’t cooling and all the fans are working. The coils inside the freezer aren’t cooling. I’m gonna test out the “relay” as he is calling it in this video. I had an appliance company tell me I needed to replace the condenser. If it’s just a relay then it looks like it could be an easier fix..

[@bwguardian]

@@CS-gd9nq mine has no codes and the evaporator coils in the back of the freezer compartment only have frost on the pipe above the coils which is telling me probably low on freon or bad seal in compressor given the readings aforementioned...

[@CS-gd9nq]

Soo if you take a black light the filters from what I learned come loaded with a material that will light up bright neon yellowish if you have a freon leak. If you have ac lines you can connect them pretty easy and if they hold pressure then you aren’t losing pressure.. if the problem still consists then you need a new compressor.

[@CS-gd9nq]

Freon leaks are pretty easy to fix. I found a few videos on KZbin that were really helpful but if part of your coils are freezing that sounds like a circulatory issue have you checked your fans??

[@najashimajashi3786]

I'm glad I found your video. Thank you.

[@twowheeling3214]

This is a great video. I have the exact same fridge from 2013, same model compressor and I get the 22 22 like you do with no LED blinks on the PCB. LG was quick to direct me to warranty repair, sent me 5 local contacts who want $1,000 or more to come and fix it while the "inverter compressor" which LG and Samsung proudly display on the sales floor as 10 year warranty, the best in the business but with no teeth. Like you I found out that the 22 22 doesn't really mean a bad thermistor assembly (next to the compressor) because I replaced it and same 22 22. By the way I am told this compressor has no relay in this kit as that function is controlled by the PCB. I also have a reading of roughly 9 ohms across two pins and nothing on the other two. The compressor does fire up but rarely gets hot to the touch which I am told is normal as well. Watching your video, I am now inclined to think that LG was too quick to throw this in the bad compressor bin (I should have known as the tech support rep told me it costs about $60 for someone to fix, clearly had no clue). My issue is that I get air in the fridge compartment from a side left vent (closest to the left door) but nothing from the back vent. The vent in the freezer works but blows warm air. What I am trying to figure out is if it's the fan (in the fridge compartment) or the PCB board or a bad compressor or lack of freon (which means there's a leak in the system). I imagine if the PCB board is bad, would it result in one of the fans not working? Is that the core issue? How did you know you had a bad PCB? Sorry, many questions and I hope you are able to help.

[@michaeldesimone2011]

Dear two wheeling, my broken refrigerator scenario is very similar to yours. Mine is 2012, with almost the same issues (left upper vent in fridge blows, nothing from back vent, warm air in freezer) I am/was holding off on the compressor replacement but instead ordered a refurb PCB board. After swapping out the PCB boards, I get same results, 22 22 error code, only warm air. I found out that no diagnostics light flashes means the board thinks all is working well. I was going to rewatch video about the start relay / thermistor when I read your post. How do you get to back upper fan? Do we both have bad evaporator coils? I have as many questions as you do...

Best video on troubleshooting and giving advice. My went bad when I lowered the the temperature. Both the refrigerator and freezer.

The compressor is vibrating and sounds like it's working but nothing is cooling at all. So can that mean i have a refrigerant leak? Or cab the compressor still sound like it's working and just not be functional?

I have a new LTCS20020S 20.2 top freezer. Here's what I know: 1. My first one had a weak/faulty compressor from the factory. Freezer was fridge temp, fridge was room temperature. That went back thanks to store and not manufacturer policy. 2. Second fridge had an evaporator fan that died almost immediately. There's a 3 pin (older) and 4 pin (newer) fan. In the 20020S the service manual calls for the 3 pin fan and it will not fit in a 4 pin application. The 4 pin fan's yellow wire is not doing anything in the quite thankfully "dumb" refrigerator, and the OEM replacement part is more robust than the OEM factory part. My fridge went from frozen coils in a cold freezer and warm fridge to actually functional. I did find and buy the correct 4 pin fan which is also curiously larger and a different case shape than the original despite the same OEM part #. It was less than $40. I'll keep my "donut spare" fan that works but is missing a 4th (yellow) wire [solder and heat shrink new fan to old plug, yellow not connected] for a rainy day, but let my frustration be your guide. If you couldn't run fast enough to avoid being given an LG refrigerator or you bought one intentionally because their other products aren't 100% crap (especially their portable air conditioners) return it. Failing that, if the freezer and fridge are both warm and plugged in, return it by any means necessary if possible. If the freezer is really cold and ice is accumulated, clean your condenser coils at bottom if dirty and check that your evaporator fan and condenser fan both run when the compressor is on. No experience w/ the condenser fan, but the evaporator fan is replaceable with a Phillips screwdriver, small zip tie, and a 10" piece of duct or foil tape. If your refrigerator doesn't blow air, it will most definitely suck.

No lights on the PCB no error codes, running amps 1.6 Amps. Suction side of the compressor cold to the touch and output side warm/hot. Compressors bottom hot to the touch. All fans work ok. Takes more freon then needed to cool to 32F. What could be the problem??

[@2171Manny]

Thank you for the tutorial to fix the refrigerator, I have the same model and brand and still trying to fix it because the freezer does not seem to work at all. I'll try to follow your instructions and hopefully it will fix it. 😄😄😄

Hi, I noticed you have multiple videos but it looks like the videos are covering the same subjects. Either way, all you videos are very good and have been most helpful to me and my similar situation. I believe I have a LG Refrigerator very similar to yours with a very similar problem. I hear the relay click when I put the plug back in, but I also have no lights on PCB. Your videos are THAT much more valuable to me as my quasi-local LG repair wants to come out and replace my compressor (still under warranty) and gouge me for $500.

[@KooperSalmo]

I believe if you’re coming pressure is under five years old you can get them to pay for labor but you need to call algae customer service direct

I replaced my control board in my lfx28968st lg fridge and still have code 22.................

[@michaelbenson5395]

What issues were you experiencing with the fridge? How did you verify that the PCB board is bad rather than the relay? My fridge is cooling poorly and get the 22 code as well. My board doesn't seem to have a LED light. When I press the test button, all fans work and compressor turns on. Freon level is good. I checked resistance on thermistor and it seems to be good as well.

[@davidramirez3693]

Did you disconnect the fridge? Or did you test the compressor with fridge connected?

[@davidramirez3693]

My Ohm readers was about 5.1

[@aayala302]

Great video! My compressor and thermal overload went bad as will with really high resistance values. I have the FLB075LANA but have read the new updated replacement part is FLS075LANA part number TCA38151706. Should the circuit board or software be updated replaced as well if I purchase this new compressor?

Great video! I have a Kitchenaid model KFIS29PBMS00 with dual evaporators. I have ruled out door seals, compressor, condenser fan, condenser coils, evaporator fans, and thermisters. All diagnostics pass. Fridge is at 45 degrees and freezer at 27 degrees for several months. I am down to either the 3-way valve or main board. How can I test my 3-way valve and/or main board? Thanks.

Joe Abb 3 hours ago Hi, Michael, I have LG LMX2596ST refrigerator which I bought 9-10 years ago. It does not cool on both compartments, so I checked the condenser which is good, I changed the evaporator coil assembly (New); I changed the LG 6500JB2002X Temperature Sensor, Single Unit; I also changed the thermistor assembly, but it still is not working. what do you think I should do next? I bought refrigerant to put into it but I am a bit hesitant, so would want to explore other checking points.

nevermind, i see the website i got it from says tilt connector 45 degrees counter clock wise

[@Ruinedmach]

So is it safe to assume that if everything appears to be working, fans, compressor, thermostats and the led is not blinking at all that the board is bad? I’ve tested everything I could with a multimeter and everything appears to have passed but the led never flashes, and the fridge isn’t cooling.

[@dahveedl3133]

Same diagnosis with mine as well. I'm hesitant to purchase a new board on faith that the non blinking LED light signifies a faulty board. Still searching for confirmation.

I have a linear compressor. It used to make knocking noises in the past, but they would go away, RIght now, it's vibrating like the fridge is OK, but both internal fans not running. Sounds like control board?

[@harrysue1418]

No error codes. Diagnostic LED not flashing. Compressor running, but coils are warm. Now know there's only one fan. In the two test modes, I get air flow thru the top in #1, and only the bottom in #2. So damper works. Must be no freon or a wheezy compressor. Bummer,

[@trickyynicky]

I have a LG with linear compressor. Runs and sounds normal, temperatures will intermittently rise and I get 6 flashes on the LED on the PCB. All fans operate normally, and the coils have all been cleaned. I’m stumped, any ideas?

[@smokymance]

I have this same issue. Did you figure out what’s wrong with yours ?

[@Ashroyer86]

I think it was appliance guru who said on linear all the resistances on the coils should be the same. Are certain fridges different?

[@ELEVOPR]

Good stuff, I hear my compressor running, but its not cooling. I don't hear the fans running but I did see the middle inside the fridge run when I pulled back the panel and locked the doors it started running. Also the fan in the back of the Fridge near the Compressor is also running. I wish mine was the Relay, easy enough to change, I will be checking the Board and do that test and if my LED doesn't light it, then it might be the board. You are saying if my compressor is grounded its not worth fixing? My Fridge is only 3 1/2 years old. Im sure a compressor would be cheaper than paying 4k again? Thanks again for sharing ;O)

what's tricky with these new LG linear compressors is they seem too be running even after they have gone bad. so the fridge can be running with the fans and compressor but nothing cooling. these LG linear compressors are trash too, only having a life span of 5-6 years

Hi again, so I have the LG LFX28978sw/02. Everything I checked seemed to work, the LED light did not work when I walked through the test button. I disconnected the con21 plug and tested the board and it only got to 150 volts not the 200 the test required. Anyway my question is, is there two evaporator fans or actually three, in the LG. I know there is one by the compressor and one in the back of the freezer and they both work, but is there one inside the back of the refrigerator as well? Thanks, guy

[@blockaderunner]

my fans are Not working

[@travisdietz2776]

Good evening, I just purchased this PCB board and installed it in my LG refrigerator model # lmxs28626d and it still shoots that same 22 code. That code says it’s the start relay for the compressor I tested the relay and I have continuity and test good. I changed the temp sensor in the freezer and I tested the old sensor out of the freezer and fridge both indicate around 6.8 ohms and slowly increases when put in ice water. I tested the 3 poles on the linear compressor 7.8 to 9.0 ohms out of two poles and nothing out of the others when switched around so that indicates a good compressor. My problem is that the freezer will cool the water down to 40 degrees and the fridge 46 degrees I open the door and I don’t feel the fans in the freezer blowing When I put the fridge in test mode everything turns on all fans turn on and the the blend doors open. The compressor changes tone and is blowing cold but as soon as I take it out of test mode inside fans turn off except for the small fan behind the filter the compressor continues to run but changes tone slightly. I’m at a loss to why everything works in test mode but not out

[@jaimeblazer2002]

Fans only work when doors are closed

[@Resist_JWO_1984]

LG with Linear compressor with inverter on the left is not cooling. Compressor starts for a few minutes then stops. When compressor is off, refrigerant PSIG at around 85. PSIG only drops to around 74 during those few minutes compressor is on. I couldn't get a solid number on the comp winding (probably 7/8 ohms not sure), because it was jumping up/down all over meter's display. Ground was ok. What is the reason only 10 PSIG dropped during several minutes compressor is on? Can linear compressor run without changing PSIG? Is compressor bad? Is the inverter bad. Is the ECB is bad? With the "old" & "inverter" comp style, refrigerant will be dropping non-stop while compressor is on until it equalized (let's say 0/+2 PSIG) but with this, linear comp, I just don't know what is at fault. Any idea?

My LG is not cooling. The fans are blowing, the condenser is humming, I felt airflow in the fridge in both test modes. The LED on the board does not flash. In the video you said your board is bad because the LED doesn’t flash. Does the light not flashing mean the board is bad or that everything the board checks is fine?

LG sent a repairman (after 3 weeks) who replaced the compressor. 1 week later it stopped cooling again. 3 weeks later again the same repairman replaced the condenser. 1 week later it stopped working again. 3 weeks later again another repairman came out and said he’d have to replace the compressor and condenser and flush the lines.

We tested our compressor, same model as yours, and the repair guy said that it was busted. At first he said we needed more Freon, which we asked him to add more to it. Then when he hooked up the Freon meter, it said the Freon was 54 F degrees inside. He said, that's bad, it should be cold. So then he said, that the compressor is bad because the freezer temp is 54 F. Is that true? I feel like we have been bamboozled.
