Genius solution. Just got Kenmore fridge from the client the same way you did. Will do the same. Not about to spend 400+ for a compressor and a firmware rewrite tool. Thank you. You ever in NYC, beer is on me.
How do you wire the compressor at the circuit board area in order to send 120 volts needed down to the compressor so that it comes on as the same time as the condenser fan?
This was very detailed. You made it easy to follow your video. I slowed the video speed and took pics of how wires were connected. I got the schematics to refrigerator and tied into the condenser fan wiring and the rest was easy. Thank you for the video.
@@devoncrampton5223 You should use the temperature/pressure relationship technique to charge with in such cases and not rely on the nameplate data. With the right amount of refrigerant you should be able to achieve around -20C. The refrigerator side can be adjusted to suit if the freezer gets to that range
Just had my son’s 7 year old LG compressor done this morning, fortunately on extended warranty. Tech was LG authorized and compressor was here 2 days after ordering plus motherboard and software updates. Took about 90 minutes, lots of equipment needed.
@@dporrasxtremeLS3 All on Extended Warranty purchased at Home Depot Canada. I only had a month or two left before warranty expired so very fortunate. The best part other than not having to pay for it is that it has operated 100% perfectly ever since. Obviously a design or manufacturing fault. Good luck.
Fantastic instructional video. Does it matter if the conventional compressor is smaller than the original linear compressor? Since the conventional compressor is not a variable speed and does not provide a pump down option? (this I am not completely sure of, please correct if I am wrong). I am going with the assumption that those features will not work with a conventional compressor. With that said, original spec on my LG is 5.01oz of R134. Since the pump down does not take affect in these dual evaporator system with a conventional compressor. Should the amount of R134 be doubled? Reasoning, since the original design called for 5.01oz in a dual evaporator system . With the pump down taking place and the 3-way valve closes one evaporator off. Should the system be filled with 10.02oz instead. My logic here is the system needs 5.01oz per evaporator after the 3-way valve pumps down and then closes. I look forward to hearing from you.
Nice video but you should really be flowing nitrogen you probably have a ton of crap under every place that you brazed, going to cause a restriction which will cause cooling problems..also should use an evacuation pump beforehand
Bought my 1st LG REFRIDGERATOR 6.5 YEARS AGO, thought they were a good brand at the time. They have proven me wrong big time! First I had the local appliance repair co. come due the ICE MAKER not MAKING ICE. Fix $248 and change, no fix, compressor bad. Good news compressor is under a 10 yr. warranty but I have to pay labor(they got you again)$450 labor.Repair man here only 2 hrs and he is paid hourly and was LG'S MAN THEY SENT. At 25$/hr that's 50$ so where did the other $400 go? The fridge made about 1/2 bin full of ice then has went on the blink again. Called repair man and told him the news. He is supposed to come by when he is in this area again! What a deal is this. .........RAY W.
The really SAD story is this. Looking in several stores(Lowes. Home Depot. 3- Badcock stores (EASTPOINT, ST JOE, AND P CITY) and only 1 badcocks could get a fridge here as soon as 3 days but that was another LG for 3,000$ plus delivery and supposeably set-up (COST $139 DOLLARS). We were assured by the sales lady the men would set-up and move the older fridge out the kitchen door and 4 steps to where I was going to hook it to hot water tank inlet water line to make extra ice. Delivery men called thirty minutes ahead BUT SAID they did not move furnture or the old fridge, so then it was to call the sales lady and let her handle this problem. The men showed up and uncrated the new box, and came in they never said boo to us. They were very rude looks and did not talk, which was a good thing.because by then I was ready! NEXT CHAPTER: NEW FRIDGE IN PLACE AND MAKING ICE AGAIN; After 7 1/2 days going to buy ice twice a day to ice 4 four coolers and ice tea. The new fridge ice maker stops and ice ran out on the 17th Opened up ice maker door and found the shipping tape and all the other factory stuff still in place. That and the fact wife noticed the handles on doors were upside down and on the wrong door the day after delivery, she calls badcocks owner(IT'S THE ONE ON TYNDALL PARKWAY). Guess what, the lady must think her customers are all fools, she tells my wife that no the delivery men are not to move old stuff out for new stuff to take its place. WELL HOW BOUT THAT, I'M 81 AND WIFE IS 77 AND SO GO FIGURE, how does she think we gonna move appliances out for hers to go in. I DON'T THINK SO! ANYWAY , just giving yall a heads up so you can prepare, THANKS: RAY WALDING
Hello there I have a lg french door refrigerator and it had suddenly stopped cooling.It had been giving the ff error code so I replaced both freezer evaporate fans and still its not getting cold at all and giving me the ff error code. I have do idea what else it could be and was wondering if you had any idea what it could be. Any help would be appreciated thank you!
had code 22 but the board was no good. Test for 200vac at 2 pins to the right on con1 for compressor. Unplugged connector/ after pressing test button once. It ramps up to 118vac not enough. Also no led indicator lights on board. If you have a 22 you need to take extra steps to rule out pcb board. Hope it`s not the comp. but not having 200vac is a problem lol /was that a map torch ?Where did you buy that torch reflector?
I am a LG tech and I would love to know how you did this. This is pretty amazing. Our control boards sends variable voltage to the compressor I wonder how did he get it to send 120 volts continuously and how does it correlate with the sensors
Based on the video, they are using a relay driven by condenser fan output to turn the compressor on. The original variable voltage output is not used. Condenser fan output should be at constant voltage and on whenever compressor should be on, so perfect for operating a relay.
@@akomakomakom Just had my 2nd linear compressor failure (in 7 years) and replaced. I wish this was an option for me. I guess I'll wait 3-4 years until this 3rd one fails and see if someone has a non-linear compressor retrofit option.
I used an Embraco FF7.5HBK1 (1/5+ hp) on a LSXC22486D door-door fridge and it's working fine. Seems to have plenty of capacity .... easily gets the freezer to -10f and cycles normally.
There are several problems with this install. First is when the board doesn't sense the comp running it will error out and shut off the cond fan, this will shut off the comp too. It will run for a little while shut down on error and stay off for a few mins and then restart. The second big problem is why in the world would you use a hardstart kit instead of proper comp relay? Hardstarts should not be used on any refrigerator made in the last 25 years as they will fry the compressor windings(the hardstart cap is 40 times the capacitance they were designed to take). Honestly though its still better than the LG linear comp. I don't know if this will work for dual evaps though, I'd be willing to try it because I've got a ton of Embraco comps sitting on the shelf.
Older models can be converted because the inverter does not get monitored by the control board the way newer models do. As for the hardstarts, what burns out the compressors is using the RCO410 when you should be using the RCO810. The 410 has an overload with too high of a locked rotor amperage rating so that burns out the compressors when the compressor short cycles for whatever reason. Short power outage for example. Overload takes too long to cutout and burns the start winding a little everytime it cycles. Hardstarts are meant for one purpose and that is to start a compressor that won't start without a cap assist. I've had occasions where a compressor will not start with a new oem relay but does start with the hardstart. I only use them for that purpose and I wire in the oem overload because it mounts to the compressor and gives thermal cutout protection and proper locked rotor amperage cutout.
Conventional are the simplest. The Embraco inverter models are very reliable, it is the control boards which may fail first within the first 5 years and replacement is DIY and about 80-100$. Cheaper if you know what you are doing...
There are 4 wires to the condenser motor. The pink and white/red wires are the only 2 that gives 12 Vdc. It is also noticeable that once power is applied to the control board, 12 volts is available, and the fan doesn't start until after the system has run through diagnostic checks and go to normal operating mode. 12 volts is always present as long as power is on. How do you control the cycling of the compressor when the set temperature is reached and what happens when the system is in defrost. Very anxious to this cause I'm trying to fix one of those same lg.
It's important to get the power supply wires to that fan. The other two are pwm and feedback wires. On my fridge (LSXC22486D) those wires were gray and black/white at the board, but red and black at the fan. When my fridge starts, the power supply to that fan does NOT come on until the board enters the compressor "on" mode and it cycles on and off as it should. I suspect that either some models control that fan differently or maybe some people have tapped into the wrong wires but it worked perfectly for me.
i am so mad at LG (loss good) 2 years old fridge and the linear compressor is shit what a bad company poor engineering all of this to save couple dollars of electricity per year
Hello, I have a LG fridge with an LG compressor. I bought an embraco 1/4 hp compressor to replace the old one. What else do I need to buy or do to it in order for it to work? Any advice is greatly appreciated!
As a refrigerator repair man I see some of what you did. The inverter board is still in the circut because it controls the temp, defrost, lights, etc. I would think the inverter logic would fail by not having the LG compressor hooked to it. It looked like you jumpered to another place on the inverter to fix this? Explain?
I was wondering I have a embraco going in to my lg refrigerator. In the video you have a blue and black wire coming from the high voltage of the board, mine is grey and black I believe the gray one is common the other black one is used in your video going to the relay. I have put my gray wire to white at the plug and added a extra black coming off the black wire on the plug that supplies power to the refrigerator. I have also spliced in to the gray and pink at the top of the board down to my relay . Any help would be greatly appreciated 🙏 I am using a simil
don't understand why you remove the brand new style compressor the one with the red sticker is the new style compressor. and put in an old rusty compressor with known problems.the compressor he shows at the beginning versus the compressor that's shown at 2:50 are two different compressors and the ladder is the old one. it's a matter of time before that thing's dead. plus it needs to be reprogrammed that's why the compressor dies
Those two wires have direct 12 volt they do not shut off the relay that you are using for the compressor🙄😔 You still need to add FL-3FF-S-Z relay module 5v. to the signal Orange wire that turns on the fan coming out by the condenser fan or PCB, Blk & Red=12v...
HI,I have a cuestión,do you recommend buy a LG refrigerator with inverter linear compressor? It's true the compresor It's not good,and what brand of refrigerator you recommend, thank you for you help.
Got a question I know how to do this one have you gotten to work on the new lg with the fans that have 4 cables? Red black yellow and purple? I can’t figure out which one is the one in the main board it just has numbers
Have you ever done this on a Kenmore (made by LG) linear compressor? I have the problem that the CFAN is multi speed and I don't know how to get a signal to the compressor as this is a 4 wire compressor fan, any ideas would be appreciated
Hey, Just take the multimeter and test in the 4 wire plug. Look for 12 volt. Them look for continuity with the plugs that get in on the main board. And them just take the 12 volt from there.
Get a Pwm to constant voltage output converter and a led driver module. The pwm input on the converter will get the Pwm “signal” wire from the control board. The converter then uses the led driver to activate a solid state relay
But can you do it with a 4 wire condenser fan motor? The answer is. No. Im fighting that battle now. The Pwm signal to the C-fan motor doesnt have enough umph to activate a solid state relay. And the + wire to the C-fan is always +12v... which means no “control” over the compressor. I wrote up a arduino code to use the pwm signal to activate the relay, but the Fridge motherboard didnt like the power consumption of the arduino... Round 3 im going to try a Pwm converter and separate power supply to see if that will work.
@@arappliances5979 I got it working. I used a $6 pwm input to voltage output convert, a 40amp SSR and some simple wiring to run a conventional embraco compressor in the fridge that uses a 4 wire pwm controlled condensor fan. So far it works like a charm.

@@ApplianceRepairinColorado can this install be done on a dual core lg? I have a dual core lg compressor job and if t could work, I'd really like to do it
@@charlesbeswick8961 Technically yes, it will work, but in most cases, you can get a new LG linear compressor from LG for free, why are you want to install the not original compressor?
@Charles Beswick read a post from another guy who said he did about 20 of these on units without the 3 way valve and had no problems but he had problems with 3 units he did that had 3 way valves. So I'm not sure..
I would flush the system with nitrogen before soldring it together so it gets no residue from the inside . Then vacuum and fill. But i don't know much about fridge circuits. I build HVAC
My compressor just went. LG said compressor was covered under warranty but not the labor or software update or anything else needed. Debating if I change out myself or have their techs replace compressor. Not sure what something like that would cost. Techs want $100 to come out and diagnose then give me an estimate.
You can make your own out of Stainless Steel Sheet metal. I seen i guy use and old spoon and he bent it and clamped it to his torch tip. It worked just fine. I was impressed.
good afternoon, I'm a refrigeration-air conditioning technician, I have a fridge like that and it's the motor that doesn't work. with the video you made there are some connections that I don't understand. can you give me some explanation?
Use a thermocouple to show us accurate temps. You showed 41f for fresh foods and 11f for freezer...way too high...41 and above is danger zone for pathogen (e coli, salmonella, listeria) growth and 0f is required for freezer long term storage. Spoilage bacteria grows above 0f and doubles its growth every 5 degrees above 0f. So at 11f, food in freezer will eventually spoil...it won't hurt you like pathogens but will taste horrible.
After Texas freeze ran into several LG refrigerators that were no longer cooling after power was restored. Even after several days. Compressor and all fans running. Reset board. Any ideas?
There us a friend who has a refrigerator just like that only lasted 2 yrs and compressor gone and if I could get a schematic of the wiring I would be able to repair it
On this model the Two wires he is using are the White/Red Wire and the other is the Pink wire. If you look up the schematics on your fridge it will show on there.

@@euphony62 the condenser fan will not run during defrost. And, really even if it did, no big deal the heat will go up and warm the coils, before warming the food,
@@bluuedaniel the challenge is that the compressor runs all the time with the power cord plugged in. It doesn't stop during defrost or when the temperature settings is satisfied, because those two condenser wires are always live 12VDC. Anyway I figured out how to use the defrost circuit to stop the compressor during the defrost cycle. I'm just not able to cycle the compressor when the temperature is satisfied.
Can anyone tell me where to find one of those 12v relays?? I’ve been to my local refrigeration supply store and it auto parts store nobody seems to know what I’m talking about? I know the coil has to be 12 V and it Has to be able to switch 120 V but can’t seem to find one
now im stock. the new fridge has 4 wire to the condenser fan. any body know how to wire the compressor to a 4 wire fan. in the tutorial i followed, there was only 2 wire on the fan ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KL9BI7fCMO8.html the is 2 wire giving 12v dc alway. But there isa 3 wire its 0,6v dv when fan is stop. and when fan is On , its 1,63v dc. and a 4 wire arround 6v dc always i saw in the comments some people manage to wire the compressor to the defrost circuit
there maybe another way to make it work. pwm to dc voltage, i working on that now. its a small device conveting the fan pwm voltage to a stable dc. do your reseasrch
Where can I get the relay? There is so many options for relays and I want to make sure i get the right one. I have the new compressor in and the last thing I have to do is to wire the condenser motor

This happened to us with an LG 8 years old. Problem is the actual refrigerator is set up nice, rollers on trays doors open nice shelves all adjust up and down to whatever height. Yes was warrantied from LG, finally found guy in Bennington, Vermont who would come over and diagnose. After 2 weeks and bought a new Whirlpool side by side just to get by $2000 with $350 in lost food. LG out in garage for almost a year to prove itself. Then we brought it back in and have been using it ever since. The Whirlpool side by side has issue with electric door from freezer/refrigerator wall that controls temperature in refrigerator side not working temperature fluctuating in the High 40s. Called Whirlpool they can't find repairman to do warranty work. Plus the interior of the Whirlpool sucks, can't adjust shelves, and sliders are friction style. And when this LG compressor dies there will be another one installed. The technician told me to try and find a refrigerator with the large cooling grate on the back said these were the most efficient and reliable. One more comment, I hear no one speak of Danfoss compressor? I have read where they are one of the best on market unless they were bought out. When the technician from Colorado brought out the temperature probe checking temperatures , did anyone else notice how high the temperatures were? As an aside after that experience losing that much meat I bought what I thought were temperature alarms for RVs. Still using them but they have no alarms. SensorPush Company is the brand of sensor you want, it attaches to your phone for real time temperature monitoring. But these are expensive. LG in kitchen small freezer in closet and Whirlpool and old top and bottom given to us from neighbors plus large chest style freezer also in garage. So 8 sensors at $75, control base at $99 so have to sneak up on that purchase.
you are right but this is not normal i wonder why we are at this point a fridge is old technologie we the stupid customer are paying for cheaper parts and bad engineering
if you do not care about possibly burning some ones home- more power to you. all for what saving a few bucks.when i do a job correctly i sleep like a baby. no worries
