LG Refrigerator High Side Restriction Locked Piston

5 flashes on main pcb found high side restriction in condenser coil.
All sealed system under 10 year warranty.

[@Blacktopmafia660]

You make life easier on yourself by pulling the compressor out. Theres plenty of suction line to pull the compressor out in the open to un-sweat the low side. Just reverse the process when putting the new compressor in. Most techs I run into hate working on lg, but I love em. They’re making me lots of money. This year alone I’ve done over 200 compressor replacements on lg refrigerators.

[@dandinhofer9240]

Have anyone in South FL that'll love an extra doing mine?

[@victoragresti1777]

Is it required to change out evaporator coil,or condensing coil on some of units

[@mel904]

Advise, disconnect the compressor lines with tubing cutter, much faster. Use nitrogen purge while brazing to prevent oxides, use a smaller torch tip like a type 17 #1. You need to evacuate down to at least 350 microns and hold for 15 minutes.

[@a.r1832]

You are right: was looking for the nitrogen purge prior.

[@bronzy2020]

I need your advice on my LG french door refrigerator 4 door same type he is working on its not freezing but I can hear the motor working, the technician changed the motor and filter not condenser. Is there a leakage in the line that's why it's stopped freezing after 5 days of working very well.

[@DaddyBLUE90S]

Why takes so long to braze each joint? I get it’s steel to copper but still with correct rod it should take couple seconds each joint..?

[@kief4diamonds]

Get that flame a little closer, hot, low glow, back off pow boom and tada. Should take you about 10 seconds per joint depending on how tight it is.

[@johntrauger68]

Forizzle

[@RobertLanghorn]

Oh no! You can't use 15% silver/5% phosphorus based filler metal on a steel to copper joint. That looks like sil-fos 15. Those joints are going to get you a call back. Use 45% or 58% silver filler metal. The phosphorus causes the joint to corrode. More so than the galvanic corrosion caused by the dissimilar metals. You're doing a better job than most. I hope your boss appreciates you.

[@ApplianceRep]

Learned that over time yes using 45% now

[@jesseguerra3734]

15% steel to copper does not cause a leak. Lock ring leaks faster than any joint in refrigeration. Its the heat you apply that causes the leak. What are the physics according to your facts that steel to copper cause a leak. Wait Korean steel, Canadian steel or American steel . They all vary. I know because, Korean steel dies not take well to 45% silver. . Canadian or mexicos manufacturers, for Electrolux, only like 45% silver. Or blue or orange flux sticks. Just asking for scientific break down. Pls

[@RobertLanghorn]

@@jesseguerra3734 Go look up what the filler metal manufacturer says. Don't take my word for it. The phosphorus damages the steel. That's what I understand.

High side restriction, or compressor failure? Looks like compressor replacement to me.

[@jpthsd]

There is a KZbin video shown that LG using steel pipe on the upper section "foam" , I wonder if LG corrected that wrong material usage in later Frig models , WHY, because steel will be corrosive and leaked and losing pressure thus no cooling/cold at all

[@XPxAxBxLxOX]

run nitro through the high side to clear the cap tubes and it also cleans the system so you get a better and faster vacuum

[@ApplianceRep]

XPxAxBxLxOX cool I’ll try that next time

[@misterindependent7994]

Also Nitro helps eliminate copper oxide contaminates.

[@allenscott228]

Just a video of someone working. All I learned was that Rent-a-fridge stores keep charging for broken appliances and most likely for the repair.

[@craigslist-tq1uf]

Took too long to heat the joint causing the Shrader valve seal to burn (3:55) and introducing a slow leak at the Shrader valve. Maybe you noticed and replaced the core; otherwise, guaranteed future service call for low refrigerant.

[@misterindependent7994]

Get some wet rags and/or cool gel to keep the heat from traveling far from the joint casing more contaminates. If you do it right you won't need to pull the shrader. The wet rags can save you the trouble.

[@badboidenis]

Wet rags can stick to the metal, paper towel doesn’t

[@misterindependent7994]

I dont have that problem with the wet rags. Your rags may be different material. Good to know paper towels are an option.

[@badboidenis]

@@misterindependent7994 yes, maybe. Just saying that when the metal is that hot, rags depending on the material (I guess) can stick. That’s why I prefer a really wet paper towel.

[@dandinhofer9240]

OK. So is the sealed LG system a defective design due to piss poor engineering by the company??? If not why are so many ones failing. Is it due to heat dissipation issues with a cramped condenser that should be spread along the back? Did the old 60's and 70's fridges last 20 years because the coils had more "room to breath" and kept the compressor running cooler? I noticed how closely installed and cramped the guts are along with a little fan. What's up with that....

It is well past time for there to be a newer and safer way to attach freon lines in indoor refrigerators besides brazing. The only excuse anyone gives is "oh that's just how it's always been done and it works so why change it". Time for the refrigeration field to update

Propane is a great rifridgerant that doesn't mess with the O zone. I wonder about it's operation next to electrical components though.

Some of the crimp fittings are very affordable, much more expensive then brazing. They are both just as likely to leak. Not likely if installed correctly.

A little harder to set it in place with the lines attached, but often times a whole LOT easier to make the braze connections!

Do you Flow nitrogen through the system when you braze. How do you determine if there's a clogg in a capillary tube

[@ApplianceRep]

David Beltrán this was a previous call back with ongoing issues. I had already diagnosed with the high side pressures and low side pressures. The high side was in the high 175 200 psi with the low side in vacuum compressor would overheat and give out an error code. As far as nitrogen in a compact system like this it’s not necessary since the lines are mainly steel and aluminum.

can you tell me how much psi this refrigerator has

[@ApplianceRep]

MANUEL NUÑEZ it’s going to vary depending on temp inside the unit. So for instance here on startup your going to have like 30psi on low and 80 on high once the compressor ramps up to full speed it will drop like 0-10psi on low and 90 on high. When you are tapping the system because unit is not cooling your pressure should be in between 0-10 psi. If you see pressure like 30 psi or higher you have to turn off unit and see how much it equalizes to. If it equalizes above 40 psi you have a bad compressor. If it equalizes less than 40 psi you have a leak.

I see a lot fewer of these reciprocating compressors fail, but still some! Never had a condenser plugged up. Filters? Yes. A couple cap tubes? Yes, and yes they stink to change on the LG. 5 Flashes on the main board just indicate the temperature isn't changing as it should, it's usually the filter-drier plugged by debris from the failing compressor.

what psi readings should you see on low side and high side? I've been searching online for hours and half say around 2psi while the other half seem to say around 15-20.

[@johninmilford7719]

When first starting/ warm 10 to 20 is in range. After the box cools down anything from -2" to 5 PSI is reasonable. Higher OR lower than that will cause poor freezer temperatures and slow ice production. •Here's one problem with using pressures to figure out if it's charged correctly: The above numbers ONLY apply to RECIPROCATING compressors! If you have a variable frequency or linear compressor, then you MUST recover the refrigerant and WEIGH it in to the system to the amount specified on the nameplate. Applies to All brands!

[@NathanWilsonDrivingDreams]

Thanks. It's linear. LG. I weighed it in and it works fine for a couple weeks at a time so I'm assuming I have a leak. Hopefully I can get it fixed before the fluctuating freon levels destroy the compressor.

[@johninmilford7719]

Definite leak. Look carefully at the connections that were brazed recently, and if there is a quick tapping valve, next time it's low, braze in a 'real' access valve. Check all brazed joints, the access valve itself, and the evaporator. In some cases there's a part of the discharge line that runs around the bottom of the condensate pan under the condenser. They sit in acidic water and corrode and leak, easiest way to test: Fill the pan hit water and add some dish soap to it and gently stir it not making any bubbles. If you see suds, there's a leak! You may have to wait a while to see it. Same on the evaporator, it's best to literally dump dish soap over the coil so it makes no bubbles. sudsy foam will indicate a leak. Just be sure that you rinse out as much of the soap as possible to avoid a blob of suds near the condenser when the fan starts!
