If anyone ever made an HVACR Videos Bingo Card, "Customer doesn't do routine maintenance" would be the free space
The hissing sound in the beginning 0:47 is coming from that huge spider in the bottom right.
I swear if I spotted a spider of that size something is getting wrecked. Lol
I'll bet they'll say "well you cleaned the return vent while you were here. So there's no reason for us to do it."
Black Widows always look like a hand painted model with the glossiest black paint.
I happened upon your channel by chance, but I don’t regret it. I’m completely hooked by your videos and I have no hvacr experience whatsoever.
As soon as I heard that compressor noise I knew it was bypassing. Started up and serviced many of these RTUs. Lennox had their shiz together on this line.
It’s like a song Chris. DIRTY RETURN AIR KILLED THE COMPRESSOR TO START 😅
It's good that the compressor was under warranty for the customer, but unfortunate for us, I was hoping you would cut it apart to see what was causing the noise. Another great video, Thanks!
I think it would have been pointless because if it really is a faulty overpressure bypass valve, you won't be able to see anything. The scroll assembly is totally fine.
Just another Lucky Goldstar compressor doing Lucky Goldstar compressor things, no mystery here!🤣
Exactly 😂
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.
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.
@@DocNo27 they have a bad reputation for ac compressors too. Not sure if they are as bad as the linear compressors, but it seems they do have a higher failure rate than other brands
0:40 Terrifying spider alert!
Helps keep the air conditioner bug free
Cute spider alert
Every office gets muggy in the morning when they line up at the coffee machine.
Ours is when the dishwashers are drying.
Watching this made me wonder where bad / contaminated / old refrigerant gasses go - and then what happens to them afterwards. A bit of an interesting rabbit hole to go down with some differing information in some internet forums. Surprised I've watched so many of your videos and just now wondered that...
I agree with the other commenter that I'm not an HVAC/HVACR guy, but enjoy watching the troubleshooting process.
Hey Chris. Ive been doing HVAC for about 14 years now, the past 10 has been mostly service and repairs. I just found your channel and I'm kind of addicted already! Like you said in your bio, we'll never EVER know everything with how this trade changes and evolves. And there's always better ways of going about the things we already know. You're good at what you do... Extremely good. Your knowledge and willingness to share that knowledge with other people is amazing! So thank you! Just replaced a TXV and Drier for a circuit on a 25Ton RTU and definitely plan on getting some of the VIPER products that you are using in this video. Ive had a lot of success with Refrig Techs other products as well. Thanks again for the awesome videos!
A tip for that core removal tool is to make sure the end snaps tight on the core. I've had to squeeze mine with pliers to make sure it grips tight.
I have replaced two compressors in the last month stuck in bypass,as one LG and one Alliance. Interesting failure I have never personally seen in a Copeland. Nice work as always.
Brown Recluse 🕷️ Spiders and Black Widow🕷️Spiders are a Lot more Common than most people realize. Most Homes have several Brown Recluse🕷️Spiders. 🤔
Lots of spiders = lots of insects. If you are a Buddhist, don't walk on my lawn in the summer, every step will kill spiders...
Hey Chris I always thought more solder was better until i created a BB and it carried through to the piston. I felt like a bone head… Great work buddy
Es un video con mucha enseñanza para nosotros que apenas empezamos gracias hermano Dios te con mucho bien🙏🏼
Working on cars I would often run some hot water over or even lightly heat the dryer with a torch while recovering to help it boil off all the refrigerant if it started frosting up.
I wouldn't do that, it could release water vapor out of the dryer as well and you don't want to have these filling up the system.
The system is going to be evacuated anyway so that would boil what little water vapour if any, off.
@@DJBJ24 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.
Nice to see a bussines owner with so many goodies!
My supervisor/owner refuses to embrace new technology,
I wanted to attend one of the Simbio classes here in Texas and he said that he won't pay for the class or my time,sad to see people like that out there ,
Nice catch on that compressor 🍻
Great brazing technique video. Thanks for showing so many joints all the way through at normal fps. I’d like to see how much of that wet rag you put back into the jar or if you discard some of the cooked stuff.
Back to Back Video's, Thank you.!
Thanks for watching
Don't worry about that first stage compressor, it'll be fiiine. Squeals like a happy little pig!
Absolutely right, Chris. You solder/braze the way you feel comfortable with. And use what amount you feel is best. Don’t let any armchair HVACR tech tell you don’t do it right, in their opinion. You know what they say about opinions, anyhow. And you know who I’m talking about… lol
wow, you just keep pumping out videos! keep up the great work!
Thank you for your videos.
You should hear the Racket My Refridge makes when it is running. I think it is the piston at the back of the Freezer compartment. NO it is not the Fan. I can disconnect it, Noise galore...
Muchas gracias por éstos grades consejos Chris. Admiro mucho tú humildad, y un gran gran trabajo.
Saludos a todo tú equipo desde Coacalco estado de México.
Gracias amigo
Yes! Be kind and don't sweat the small stuff! I like your last comment.
Exactly
I always share your vids to my guys! I hope they watch them. I certainly have learned alot from you and I mainly do residential. Would love to get into more commercial and refrigeration.
Brazing compressors, driers and sightglass and expansion valves are fun.
Too short solder should be handled with a plier, so you don't burn
Your fingers. But very nice of you to show that awsome part of the refrigeration work.
Thanks
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
Good job Chris.
I was also very impressed and comfortable with the measure-quick app…until they made it virtually unusable by removing the ability to take screenshots. 😢 I get it they need to make money. But as I’m not a business owner I don’t have use for the premium features they are trying to push by removing this feature. I just need the screenshots to remember the numbers…As always Chris, thanks for all you do!
Use android not iPads. With root you can bypass the no screenshot rule.
I suspect that the constricted return caused pressure to rise, busting the internal bypass valve.
He says "oh look a black widow, that's pretty cool"
No. No it's not. 😂
Lol
Sure it was...
It was on the other side of your screen so no possible way you could get bit by that one...
😄😁😆😅😂🤣
i agree internal bypass is leaking by. i would isolate the compressor and valve down the discharge(if you can), and see if the noise changes. You can also use a small tube, one end goes to your ear the other end goes on the compressor to see if thats where your noise it coming from, an ear plug in the unused ear help as well
Have you ever considered using rosebud tips to weld bigger piping like the suction on this compressor? Great video 🤙🏻
Possible poor heat exchange across evaporator? High air split temps, low back pressures. You mentioned possible bad ductwork.
I really enjoy following you on your calls. Helps my old brain exercise a bit! Thanks for sharing!
Thanks for watching
24:10 You should get (or have a Machinist Friend make) a small copper or brass tack-hammer (3/8 x 3/8 inch striking face) to gently tap stubborn pipes into place during Braising...
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...
Love your closing thoughts ♥
Great Video. Thank you for sharing. Have a nice weekend.
Great video Chris has always.
So now that you have a larger dryer in and need an extra 4 oz of refrigerant, do you document this anywhere? Write it on the inside of the panel for the next person who checks the system?
Neat as always, but i do wish you had the opportunity to autopsy these odd compressors to see what was broken.
I enjoy watching your videos on my down time from work keep up the great work . Question what kind on valves are you using in line with the filter drier
Awesome video Chris! 👍🏻 Lots of great tips as always 👍🏻👍🏻
Thanks bud
Did you not see the pipe pop out again on the Top of the compressor just as you moved to the second joint ???
dude was that a black widow at 0:48 when
i saw it i literally gasped and said "oh my god"
My first thought was either a bad check valve or it’s bypassing. Then I realized that those are LG compressors, well no wonder they crapped out so soon! LG compressors aren’t exactly known for their quality or longevity. Lennox’s tend to be relatively bullet proof tanks otherwise, or at least they used to be.
Awesome video😊
Thanks bud
Nice 👍🏾
Take a screwdriver, push the tip on the probable source and the handle to your ear so you hear the sound kind of directly
If you turn the unit on at the thermostat and unit not on remove the thermostat and jump out y1 and y2 then you can see if it the cable broken or the thermostat.
It's almost like you're the boss and the one who ultimately pays for the solder, so you can use as much solder as damn well please. 🙃
Methinks a cheap stethoscope would be worth purchasing 1:00
You know? It sucks you have to send it back warranty. I would have loved a teardown of that scroll assembly.
Me to, maybe next time
Nice compressor replacement 😎👍
Thanks bud
Morning mate, curious question. How do you replace the Black widdow? Funny thing to seeing them now twice in your video’s
If i worked in areas with black widows id probably have to rethink my career
How do you install the probes to get all that info?
I love watching your videos, tho i have *alot* to catch up on cus I stopped watching for awhile (i was interested in anime)
wheres the brazing montage lol!
Like to know how many months of no maintenance it takes to pay for the two compressors.
We going to start a pool as to when compressor 2 will fail?
if the buildings are cookie cutter why not add a nicer split unit with the supply on the ceiling because the walls are covered in equipment for the common office issue?
I've found so many problems with LG compressors. I don't trust them anymore.
if a york ac unit was a food it is a *old broken egg york*
I avoid measurequick after the "pay to screenshot" disaster, that and the interface was very clunky atleast at the time i used it.
I have a question?well Not related to this video. What are the differences between normal compressor and inverter compressor? I know i can googled that, but think you explain it batter.
In the video it looks like youre using an oxidizing flame during the brazing portion. Im curious, is there a particular reason for this or is it a preference?
Just preference I suppose, it's just the way I've always done it
Why would you have a aircon in a kitchen as in Australia we don't have aircon in kitchens
It's a restaurant.
What tablet do use for the app?
An iPad pro
I would have thrown that grill away till I got them a new one
Why don’t you put in Copeland compressors if the unit is out of warranty
Aren’t you guys afraid of black widows? Aren’t they venomous?
Replace the office grille with a bigger one or add a mini split
It’s turbo charged.
Are your PETA certified?
I noticed that the Sporlan Logo was missing in the Intro. Mistake?
No, just a change of scenery for a bit
That grid and duct work is awful. Love to see that stuff under a microscope. May be a new life form.
Where’s the 80s music for brazing ?!?!?
So they don't let you even dump oil on bad warranty compressors?
I will discuss this on my livestream this evening 4/8/24 @ 5:PM (pacific) come on over and check it out. ruclips.net/user/liveiwGZEoDxYvo
I'm not a HVAC technician, but why is it more common to have multiple circuits in commercial systems rather than one circuit with a big compressor controlled with a VFD for variable stage cooling?
Those do exist, but they are costly and complicated. I usually see them on server room units.
I guess i you can use of the shelf bits it is easier to make and ajust sizing, and there is allso a redundancy factor to this. If 1 of 3 clmpressors crap out, it wont kill thd whole AC, and it is no so critical. If you have 1, and 1 brakes, you are out of luck.
Cover should be taken off and Customer needs to Pressure Wash it thoroughly. 🤔👍
Why do I find it hard to write the next line
Where's your stethoscope?
You braze like your from California!!!!!
😂😂😂😂 here is your mean braze comment
The black widow will keep the bugs out
Maybe time for a rosebud on your torch? Be a whole lot quicker
Lennox went downhill when they started using LG compressors
Too much acetylene on you flame from your torch will reduce your heat and take longer to do the joint. You got it some where close once you put your rod to the joint on the compressor
First problem, LG why did you replace the other one with another LG 😢😢😢 only scroll od ever buy is a Copeland. And even then if its not 410a i always replace with a Tecumseh whenever possible 😂😂😂 i get identical compressors from my local Tecumseh dealer for 1/4 price of oems..... I can usually get a 2hp or less from Tecumseh under $700. Fractionals under $500..... Anytime i find a bad 134a compressor on ANY mfg not under warranty it automatically gets a Tecumseh 😂😂😂 the only thing more reliable are the Copeland semi-hermetics.... I have 50+ 20year old or older semi hermetic Copelands and ive only seen ONE get burned out/locked up. And that's because it had a failed low pressure switch AND a leak 😂
Probably because it is a warranty job so it will require going with OEM parts
@@atomstarfireproductions8695 nah even if it's not he's a little weird about putting anything but OEM parts in. I get it because then he can just blame the OEM instead of someone saying omg my unit failed because you used an aftermarket part. But like we know there's better 😂😂😂 the only thing aftermarket he uses religiously are sporlan parts 😂😂😂 but like theybnake fantastic parts except their electronic pressure regulating valves.... Pretty much have those ALL fail after 7~ years but like it's a TINY market that uses them so 🤷♂️🤷♂️🤷♂️🤷♂️ it's either them or some carel crap that Id never even fart in the direction of 💀💀💀
That sound from the compressor is arching between motor windings. The short impulses (high frequency) from the inverter damaged the winding wire insulation and create arching. Next time try buying compressors with better insulation rated to work on inverter or add a choke between inverter and motor.
*Question for anyone: I'm looking at buying an old Carrier unit that was never installed, years ago, in shipping, someone put a hole in the condenser coil - refrigerant is long gone, it has been open to the air for years. Am I likely to have an problems from the system being open? The unit is in the non-profit's price range. The coil can be repaired, it's a large coil. What possible problems? Thanks*

compressor autopsy time
LG compressors arent the greatest
A gentle understatement.
LG compressors are junk, especially the liner ones for residential use.
Those LG compressors are junk
