Second year apprentice in Rockford IL here doing supermarket refrigeration. Your videos have put me a league ahead of my peers, combined with the experience I’m getting in the field. You’re the best thanks
@@gendronhvac-r1269 kind words are the best way I can show my appreciation. Your videos has helped taught me a thing or two about a thing or two about service. Was a installer for most of my apprenticeship, than right as I turned out boss man told me they needed another guy on call and threw me to the wolves lol your videos have been very helpful to me. Thank you for what you do.
First time watching your videos, gotta love how calm you are about it man, can tell you been through hell and back enough to have learned patience is key man, well handled! definitely subscribing! Hands down 🙌🦾😎
Nice fix on that flare! One question about transferring oil from that tripped compressor. I would fear that the reason for the trip was a winding failure which could have lead to contamination of the oil with burnout residue. I expect you are completely aware of this but would like to know how you decide when to do this versus not do it. Those singapore noodles look fire! Love that stuff.
Really good question, In a perfect world I would leave that compressor filled with oil. Come back during the week and access it deeper. what I would do is. Make sure that the compressor is not Electrically compromised. Do a basic ohm reading. Then I would try to find out if there was some other cause on why the compressor was not turning on, for example, a safety or liquid flood back. If I deemed that there was another cause, then it would be safe for me to transfer the oil. Because it stands to reason that it was not the compressor that burned out But it was the other cause that kept the compressor from running, so the oil should be safe. I also look at the oil and see if its Dark brown or black. But in a situation like this it's a little more difficult. I might run a basic Electrical check of the compressor. Then just push out the oil If it doesn't look bad. This is probably not proper practice. But in the moment I need to get the system running, I don't have enough oil. If when I came back during the week, I found that the compressor was the issue and that it was a burn out. Then I would have to install acid absorbing filter dryers on the rack. And maybe consider doing an oil change. I'm not sure if it was the right call but it's what I had to do to keep it running for the weekend and save the food. I'm still learning every day so I don't know if there was another way to have approached it. If the store had the space, I might have pulled some product lines and had them reduce the load on the rack. But anyway I hope the video was helpful to you :)
I have had to do this exact repair several times. Always seems to be after another tech was wrenching on it earlier in the day, made the leak worse, and then went home for the day pretending he never saw it leaving it for the on-call guy to fix at 1am.
The nylog red is crappy. Stick with the blue. I will add some nylog on the packing of the service valves too when I'm running the stems in. Seems to help with the ones that are rusty and crusty.
22:45 are you pressurizing with discharge pushing the oil out of the compressor through the oil separator and reservoir and then back into the suction line?
No, My gauges are hooked to the port on the back of the compressor. Then I have another hose hooked up at the compressoil pump. That hose is fed directly into the suction. I feed the Discharge through my gauges. Pressurize the compressor. Is that pressure pushes the oil out through the Pump. And into the suction. Hope that helps
Ive learned the hardway with Nylog- spread on the entire mating surface, especially on metals like stainless. Nylog doesnt spread under the compression and can end up not sealing if theres bare area connecting ID-OD
Yes it would :) But I think in the video I showed that even with nylog the fitting did not work so even though I could use nylog I still had to redo the flare
I wish they would quit the fearmongering on A3 refrigerants here in the US so we can use R290. It's a terrific refrigerant, having even better performance than R22 did, and it can drop right in!
I have not worked with R290 very much. Do you have experience with dropping it in? I thought you needed special components that would not cause a spark. I'm honestly asking i'm curious I don't know much about that.
@@gendronhvac-r1269 I don't but I know it can be done. It's been used to replace R22 in residential cooling in Europe for decades. But you are right that you would have to use non-sparking tools when servicing such systems.
@elplevonrooo395 I never had a ton of experience with Co2. I know if a co2 rack is shut down too long. The pressure will rise and then the pressure release valve will blow. I do not know the exact way to work on a co2 rack. I just did Not want to give the impression that you could shut down any rack And have it be fine and that there is a difference in how you treat c02. But the exact way to do that I do not know
Inches of water column is just a different measurement of Vacuum. 29.90 Inches of water column is the equivalent of five hundred microns. So I pulled it 30 inch vacuum which is more Above them beyond the epa standard. The units can be confusing. The only reason I use those units is I can't figure out how to change my gauges To microns. Anyway I hope that helps :)
29.9 inches of water column Is the equivalent of Five hundred microns. I had it at 31 inches Of water Column. This is A deeper vacuum than five hundred microns. I hope that helps. For some reason I could never figure out how to change my gauges to microns.
The grocery stores by er would be finding a service company fix their problem do3s matter if it's the weekend or after hours we didn't leave until it was fixed 😂I c ant believe that you don't have any oil especially doing rack refrigeration
@@gerryminichiello929 ya, they sell the washers already flared. You just drop it in the nut and you have a new flare. Old school stuff man. Been using them 30 years
Yeah I have been burned by quite a few lazy tecs. And also I have seen lots of tecs abused By their company. Sometimes these people don't know any better And their company doesn't really give them any training. I guess it's just a part of life. Anyway I hope my videos help alleviate some of the problem :)
Putting nylog on threads completely pointless Friend. The reason is the threads are infront of the flare seal. So when it leaks it goes around the flare and out the back of the nut. Depending on what kind of flare is needed. You have to use a special flare tool. I believe it's called a orbital flare tool. The flares that it makes are wider. Plus the tool come with a clutch. Which prevents over tighten on the flare tool itself so you don't thin the actual flare out and weaken it and develop a Crack. I know this stuff cause trane classes taught me about all of it. I like your videos. Thanks. Also the reason for the wider flares is some of these refrigerants run at higher pressure so it needs a bigger seal matting surface to hold the pressure.
Thank you for your share. That is an interesting idea. I actually have extremely little experience with flares. The company I work for actually had a no flare policy. Where if at all possible, you were always supposed to braise unless you were replacing an existing flare.
I like the way you tackle problems. So calm and relax
You should title your channel as "The Joy of Refrigeration". You're the Bob Ross of this trade.
😆 that gave me a good laugh!
Then he shuts off the camera and it’s 🤬🤬🤬😡🤬🤬🤬😡🤬🤬🤬🤬
Lmao
@@SombraLocs 🤣 yes !

Glad to help :)
I felt that sigh when you saw compressor3 had a tripped breaker lol that oncall weekend is rough
Gendron is the goat refrigeration youtuber
I would not go that far 🤣
just a dude on the internet.
But thank you very much For your kind words.

Always enjoy your videos! Wish I had YT back in the day for great pointers like yours.
Black max flaring tool works awesome and has a gauge to get a perfect flare every time
Thank you for your teaching I jus started working on rocks sistem all new to me
Do you do commercial air conditioning too,or just refrigeration?Thanks Awesome videos
I repair commercial air conditioning units.
But I do not install them.
Or do like duct work.
I'm happy to help :)
Like how you show how to work on a rack that helps me a lot
thanks

Unfortunately this is very true

What the difference between red and blue?
22:45 are you pressurizing with discharge pushing the oil out of the compressor through the oil separator and reservoir and then back into the suction line?
No,
My gauges are hooked to the port on the back of the compressor.
Then I have another hose hooked up at the compressoil pump. That hose is fed directly into the suction.
I feed the Discharge through my gauges. Pressurize the compressor.
Is that pressure pushes the oil out through the Pump. And into the suction.
Hope that helps
Or can you link the video of you explaining this process? Thank you!@@gendronhvac-r1269
My favorite part is always telling the store managers i need some kitty litter for the Machine Room LOL...
I never thought of that but yes that is very funny !
Ive learned the hardway with Nylog- spread on the entire mating surface, especially on metals like stainless. Nylog doesnt spread under the compression and can end up not sealing if theres bare area connecting ID-OD
Tidy Cats to the rescue......😄😄😄😄
Great video gendron! Thank you for providing this
I hope it helps :)
Would nylog work on a flare fitting?
Yes it would :)
But I think in the video I showed that even with nylog the fitting did not work so even though I could use nylog I still had to redo the flare
I was always taught about the thickness of a nickle when flaring..
I wish they would quit the fearmongering on A3 refrigerants here in the US so we can use R290. It's a terrific refrigerant, having even better performance than R22 did, and it can drop right in!

So I'm still new to super market Refrigeration can you shut all the compressors down without pumping down the rack?
Yes,
As long as it's not CO2
You have to pump down the rack with CO2?
@elplevonrooo395
I never had a ton of experience with Co2.
I know if a co2 rack is shut down too long. The pressure will rise and then the pressure release valve will blow.
I do not know the exact way to work on a co2 rack. I just did Not want to give the impression that you could shut down any rack And have it be fine and that there is a difference in how you treat c02. But the exact way to do that I do not know
why oil colour is yellow?
It's getting old
Not like bad just has been around the block
Great job. Refrigeration life❤
Shouldn’t you pull it down to 500 microns according to EPA Rules??
Inches of water column is just a different measurement of Vacuum.
29.90 Inches of water column is the equivalent of five hundred microns.
So I pulled it 30 inch vacuum which is more Above them beyond the epa standard.
The units can be confusing. The only reason I use those units is I can't figure out how to change my gauges To microns.
Anyway I hope that helps :)
Good job
You should have made a new flare and been done with it
I think that's what I ended up doing.
But still learning every day !
appreciate you
Isn't 500 microns like -29.95" of mercury? -29" of mercury is like 25000 microns.
29.9 inches of water column
Is the equivalent of Five hundred microns.
I had it at 31 inches Of water Column.
This is A deeper vacuum than five hundred microns.
I hope that helps.
For some reason I could never figure out how to change my gauges to microns.
I like your videos….
Thanks ! :)

Reusing that flare i would have put a flare washer on it.
Thank you for the comment I didn't even think of that!!
I'll have to remember that next time :)
Flare bonnet?
@@gerryminichiello929 ya, they sell the washers already flared. You just drop it in the nut and you have a new flare. Old school stuff man. Been using them 30 years
if only you could make lazy and hack techs pay for the failures they cause...
Yeah I have been burned by quite a few lazy tecs.
And also I have seen lots of tecs abused By their company.

Jobs like this end up causing me to break out like a teenager. Refrigeration oil does a great job getting into your pores.
Me too !!
Just a little bit 😂
That flare looks like crap 5hats euy 8ts leaking people don't know how to Make a good. Flare
👍🧿
