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
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.
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.

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
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.
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?
@@element_hex822 I wish I knew, couldn’t find one, but I could get impatient with his aviation snips and fashion one by drawing a plan on paper. Stupid because the metal would be thinner than you want, and would warp. It would save you 30% on gas, and you could work better around plastic, less heat time
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.
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.
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
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...
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?
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
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.
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
Hello from brazil.. my compressor was replaced for a non-inverter (i had imported my fridge from usa and can not find the original compressor here to order)… fridge is cooling but everyday the error code DH appear (defrost error)… i need to turn off/on the AC… how can i set the board to make the defrost?
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
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
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 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
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...
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.
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.
There are 4 wires to the condenser motor. The pink and white/red wires are the only 2 that gives 12 Vdc.

@@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.
@@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..
@@ApplianceRepairinColorado LG предоставляет бесплатно компрессор, но за установку требуют не мало денег, тем более компрессор меняют 1 раз, и компрессора 88 серии, ходят в среднем 1 год!
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.
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.

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.
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 th-cam.com/video/KL9BI7fCMO8/w-d-xo.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
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

Question, the boards 12v output is ac and the relay is dc so how long did your relay last switching like that?
Great video. Those linear compressors are terrible. Most of what I encounter is it’s not pumping. It’s running but refrigerant isn’t moving.
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?
Get a technician or super lawyer
Swift little attachment to the Torch head, makes it much easier to install new comp.
What torch and attachment is that where can i get one ?
@@element_hex822 I wish I knew, couldn’t find one, but I could get impatient with his aviation snips and fashion one by drawing a plan on paper. Stupid because the metal would be thinner than you want, and would warp. It would save you 30% on gas, and you could work better around plastic, less heat time
Could get handy with snips
In another video. He wrote he made them from sheet metal himself.
@@vovobillinbrazil makes sense , I couldn’t find them anywhere, I like this young man. Too bad he has the smokers hack, he should quit, of course ,!!
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.
Hey my friend how many ph is the convensional compressor ??
Ive had my LG fridge with linear compressor for 4 years, no problem at all. I think the newer models are okay.
I just had my 2017 LG fridge fail, so your likely close to failure as well... Sorry.
They have a 5 year warranty, so 4-5 years to failure sounds right.
2016 just failed on me.
@@NFPC06 , Hi Matt, you're right! I had a failed 2018 Kenmore Refrigerator with the LG Linear Compressor.
March 2018 manufactured just failed on 07/08/2022. No more LG for me.
Can this be done to a dual core lg?
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.
@@akomakomakomBro has the hack of the year , lol
@@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.
Is it possible to get more info on this repair? . I too have a problem with my lg fridge. Dennis Cook
Did you get more info about the repair?
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
Were you able to find that really
@@rockylevine7295 Yes,order it off Amazon though because they are coming from china on ebay
@@andrewbailey9197 whats the relay to order???
Pls how am I going to do the wiring for the new compressor
Conventional compressors are the best. New tech compressors like linear and inverter are rubbish
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...
Inverter nonlinear compressors are superior
So are these so called "linear" Compressor from LG are faulty and failed design actually?
@@alokpisal Yes.
I am still on my LG refrigerator where can I find the same relay
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?
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
@@invertmast hey can you elaborate? Like parts and such? I need to make this work!
Did he ever answered?
Where you get the torch tip at? Iam A SUB Zero Tech and never have any luck finding that torch tip. any help
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.
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
Hello from brazil.. my compressor was replaced for a non-inverter (i had imported my fridge from usa and can not find the original compressor here to order)… fridge is cooling but everyday the error code DH appear (defrost error)… i need to turn off/on the AC… how can i set the board to make the defrost?
Just use the aftermarket dual thermostat....
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
OEG OMIF-S-112LM Power Relay 12VDC 4Pin 20A 125VAC Found it on Ebay . Still waiting for it. Pretty sure this is what I need
can u give me exact digram of exact wires i ned to cut n splice to where to do this conveersion about to do one soon
Oh shit. I do these everyday. But ya we can’t swap it out like that. Dang that’s cool.
Oh cool. Do u think that swap would work for a dual core system kenmore?
Explain to me
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
He is using a conventional compressor instead of the linear compressor
What type of relay tho?
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?
The wiring segment was too clear for me can you do over that section or explain it
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
you do realize that lg watched these videos and changed the condenser fan power supply so you cant add a relay right.
I love the torch and attachment where can i get one what is it ?
Its called a reflector or a flame guard sometimes
So when condenser fan motor is energized the compressor kicks in on that circuit. Ok
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...
What happens if you don't do the circuit board mod and just plug the new compressor in?
LG tech did my son’s today and said software update was mandatory otherwise it won’t operate properly and also replaced other board too. 90 minutes.
@Brian Baker this is a conversion to a non linear compressor so no software update is necessary.
Can you give me more explanation on the circuit preparation
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.
What is it standing pressure
Still working?
I find it difficult to fathom what all that PCB complexity can possibly be for.
Hello everyone, I need your help. i don't get it yet. Thank you very much
What is the horsepower of the compressor you are installing?
You need low a temp. approx. 900 btu compressor
You should be using heat block on the steel lines going into the body to keep the insulation from melting.
add how many oz r134 ?
So are these so called "linear" Compressor from LG are faulty and failed design actually?
You're right, You named it! I had the same problem on a new Kenmore Refrigerator in about 2 years so I got to buy a new Whirlpool Refrigerator.
Hey very good work can you send me a diagram of the wiring you did to connect the compressor thanks
It would have been nice if you could have shown which wires go to the condenser fan out of so many, could you just match the colors?
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.
@@1xicano ok jr in chickendale
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.
@@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.
Do we REALLY need all the complex electronics to perform a simple operation of compressor on, compressor off???
have a big question, doesnt the system detect that there is no linear compressor conected?
no, previous generation lg refrigerators, do not have any feedback from inverter
@@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?
@@ApplianceRepairinColorado Cause he doesn't want to do the job every 2 years and lose food waiting for the compressor?

В России уже 6 лет назад еще научились ставить вместо линейного компрессора, обычный асинхронный!)
Все линейные компрессора LG на 10 летней гарантии, так что нет смысла ставить обычный. Ролик больше развлекательный, чем практический.
@@ApplianceRepairinColorado LG предоставляет бесплатно компрессор, но за установку требуют не мало денег, тем более компрессор меняют 1 раз, и компрессора 88 серии, ходят в среднем 1 год!
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.
LG authorized tech set our son’s this morning at -4F and 37F which he said was recommended.
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.
I know how to make that 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.

Take it from an appliance technician never replace a working appliance. It will last longer than your new appliance.
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.
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
th-cam.com/video/KL9BI7fCMO8/w-d-xo.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
Bad idea for 4 wires fan it work only with 3 wire fan
