I think there could be a quality control and/or a design flaw issue. I’ve heard LG got a class action lawsuit back in 2020 for bad refrigerator compressors. It effected residential refrigerators only but it’s very possible due to past compressor quality control issues that a new wave of defective products exists. Both compressors you replaced were replaced for bad bypasses and the compressors looked pretty new. Coupled with the previous lawsuit, I suspect that a quality issue/design flaw exists with a certain model of scroll compressors. Check the date code and serial number for each compressor you pulled out of that system if possible at this point.

@DocNo27 3 ай бұрын

it was their linear, not scroll compressors, that had the flaws.

@@DocNo27 I know it was the linear compressor but I was pointing out that LG has a history of faulty products even if the compressor type was different. Plus 2 newer compressors with similar bypass issues coupled with the fact LG is known to have had issues with some of their products is grounds to suspect that there could be bad quality control or a design flaw from the manufacturer LG.

Curious if you have had any issues with leaks around the brazed joints - I ask because throwing a “Wet towel on to cool it off” may result in the metallurgical process known as quenching instead of cooling - and quenched metal tends to be crystalline and brittle and will crack much more easily under vibration than the same metal which is allowed to cool slowly (slower cooling results in “annealing” which is not brittle

@stormeagle28 2 ай бұрын

@@BensSightSoundandAuto As you know, you'll never get a perfect evacuation (especially not in a time-tight working environment on cars), so you can't get all the vapor out of the system. You'll make it harder for the new dryer (which also has to care about moisture in the new refrigerant, often it's not as dry as "new" might suggest) if you flush the system with water vapor. There are voices out there who say, if you can cut an old welded dryer out of a system then don't weld it out.

Then there's less risk of burning your fingers pushing or giggling hot pipes...and the copper or brass face is malleable enough to not mar the copper pipes as you tap them...

@drodriguez394 3 ай бұрын

I always think about this when purging for a compressor, Your coming in through the discharge line, how do you know you have flow through the compressor through both of your joints out of the suction joint to the shearer valve? Considering the reeds, they probably act like a check valve and don’t allow flow. I think it’s likely it’s skipping both of your joints it goes through the condenser coil then the evaporator then and out of the suction valve. Even if you purged from the suction side, how do you know it’s flowing through the compressor, through the reeds passed the joints? I would think the path of least resistance is still the coils. Something I always think about. Love the content Chris
