- A noisy refrigeration call leads to more problems when you look past the obvious symptoms. It's easy to fix the original symptom but if you want to be your best then you need to look deeper into the system as a whole to verify everything is working as it should to reduce the possibility of a call back.

Have been watching the South Korean plumbers 3 days later. 🤣 lmao great job 👏
Tip for you Rick, instead of using a refrigeration wrench on the fan bolt, you can use a socket extension reversed. The part that normally goes on the ratchet fits perfectly on that bolt. Than you use and adjustable wrench to turn the extensions.
I was taught that trick by another tradesman at the supply house about 10 years ago when I struggled for hours trying to get a blade off.
I always soak with liquid wrench and give a little tap with hammer and it makes it so much easier....
I literally just bought a half inch pipe plug socket. They actually have a whole kit that is square head. I might actually buy the smaller ones in addition to the half inch socket that I ended up buying for the large suction King valve on that compressor. Basically you're saying do what I was kind of doing on the big compressor at the end of the video?
Yes,
..,And you always have the best tools...I know you keep up to date!
Great video!
You gotta love it when the set screw threads are going bad and you can't find a replacement. A little grease when putting it together can prevent the rust and the seizing , I'd love to see manufacturers apply some on these exposed parts .
Good one Rick 👍
I agree, any extra effort is amazing in this screwed up society.
Nice troubleshooting ... Good repair and good vid ...
I would never laugh at a torque wrench. Lol. There are plenty of times where your experience makes it to where you probably don't need one, but nothing wrong with using one, especially in that situation where it is important that they all be equal. As for the oil level... the sheer size of that machine makes anything I'd say just an educated guess. Well outta my ballpark. But my guess is... just as you said ... once it wasn't so low anymore, proper velocity and oil return were restored and it got its oil back. Nice video! :-)
Thanks Winston, I appreciate you feedback🤜🤛👍👍
just strip it out and back it off a quarter turn... LOL
Couldn't agree more
Thank you, great video. I really like the captions '3 days later ', that was a pretty big system great that you found that leak and solved the issue the unit had.
Thank you 4 taking the time 2 watch it👍👍
I work on those model units every day. Next time pull the top off. It’s 6. 1/2 bolts and the top comes right off.
It’s a lot easier
Interesting, I'll have to try it. Your saying take the top off with the grill in place to get better access to the motor?
@@HVACRSurvival that’s what I do that way your not having to reach over and tear up your forearms and back 1.5 hp motor kinda heavy!!!
Appreciate the time you put in to make these videos believe me I know how hard it is to put out quality stuff while working.
Takes more patience than I have. A lot of Houston techs enjoy your channel
Thanks
@@randomrefrigeration4564 thanks man👍👍. I looked at the video again and I can see how removing those tops would be easier, thanks to the info!
Nice job 👍 👍👍
Good one Rick 👍
Thanks man👍👍
I wonder why the condenser gaps vs copper where only on half, perhaps the hottest part of coil until it gets cooler further down? Maybe they didn't want it to fail in the warranty and where being safe for themselves? Those plates rust, I put some primer on mine (evap) to slow rubbing on copper from rust expansion. I often like to do preventative things like that, which can make a big difference in the long run... Informative vids as usual.
Great video
I appreciate the support Craig👍👍
Another good video! That different evap. coil tube sheet design I think is a floating coil design due to length of coil, copper expansion rate. Around 20 min. the crankcase heater looks like its falling out of the well of the compressor. Little tabs are 3" away from engaging, unless someone put wrong one on.
You are correct is was labeled as a floating coil outside. The block heater felt in place when I originally looked at it but I did not give it a pull to verify, I will need to recheck it whenever I go back.
You get a big thumbs up from me !
Thanks big bear👍👍
Highly recommend Posi Lock pullers. 19 years strong. The "weak point" is the extension tip. Have had 3 replacements there. User error on all 3.
Different tonnages
Yep those are bad ass pullers. The big ones are big money
Very good
Thanks my man👍👍🤜🤛
It's good to have some pb blaster or 656 you just drench it wipe of excess and gets those nasty one lossened up... The torch does wonders also... Nice vid
not much wins against the torch :)
You actually said washed the normal way for once haha
Oops 🤣. I'm aware of it more now than ever
@@HVACRSurvival LOL
Wait a minute here. Did tightening the bolts actually fix the leak because that is far and few between if it ever happened to me. In most cases I end up with an even bigger leak or one of those bolts decides to snap and ruin the day.
But even preassure on all the bolts is key here to make a tight seal and I see that this is not your first rodeo since you brought the torque wrench. 😀
Those evap coils are famous in my neck of the woods for leaking power heads and stems on your txv
Good to know, I'll keep a eye out for the txv's, unfortunately I didn't get any hits on them.
Looks like they need some pest control in that place 😁
Wish we could see you use the ultrasonic detector more on some of this stuff.
I'll see what I can do. I only use it when I have a problem finding it with the electronic.
That crankcase heater looks like it's only halfway into the compressor well.
Im feeling cheated. Ive got about 30 of those condensers and not a damn one has the pins to rest to motor on while bolting it up. Feels bad to see people living the dream! xD
They must be Ohio specials🤣. I've seen them at other locations 🤷♂️
@@HVACRSurvival all the way down in Texas my man! Big farms got a lot of refrigeration to look after and it’s about the season of bad motors
Replace the blade with the motor. No screwing around getting that blade off.
Mutible afender as nol cal Dave would say good work tho
Thanks Sub Sonic, they all seam to have more wrong that what first meets the eye.
👍👍👍👍👍👏👏👏
MC connector on a outside motor. No flex or weather proof connectors?
That was factory, every motor was like that 🤷♂️. It lasted 11 years
Hey Rick? Do you possibly have a link for that cheapy torque wrench?
Harbor Freight 3/8 ratchet www.harborfreight.com/38-in-drive-click-type-torque-wrench-63880.html
@@HVACRSurvival Thanx.
It cant be stuck if its liquid
Help help, hello Rick, working on same unit, same set up cooler warehouse, having foaming problems and one compressor failed looks like liquid or oil got back to compressor. Superheat at each evaporator is about 8 degrees, at compressor around 22. But for some reason oil not coming back, wondering if accumulators are getting plugged or still air flow issues? Coils are clean, new filters, vacuumed down to 500 microns. But still when running that unit is scary, any suggestions, thanks a lot
Tear the heads off the compressor and find out if it's a flood back problem, see if you're bearings are worn, if the wrist pins are wore. If you have foam in the oil it's likely refrigerant flooding back. It's hard to cover it all without seeing what's going on or hearing it. You could have a plugged weep hole in the accumulator causing the oil to not return.
@@HVACRSurvival thanks Mike. I
Will try tear it down and find out what is going on. Accumulator is ordered, hopefully week or so. Hard to find parts in stock this days, crazy time
🤦♂️ I was on the phone with Mike just before writing post 🤣🤣🤣🤣🤣
@@KninskaKapija I was gonna say my name is Mr Ed, not Mike 😁
What I find is damaged valves. Looks like oil in the pistons. Replaced valves, all filters and refrigeration. Start up unit install all probes and watch unit for performance and took me some time but definitely find one problem. Sometimes compressor goes in to vacuum when satisfying and pumping down, so pressure switch must be bad. Replaced with new one and now it shuts off at 5 psi all the time. Wondering if that vacuum could kill that plates?
Under vacuum -6 psi or so I guess that oil likes to just sucks in to pistons under vacuum. Working on semi hermetic 4 cylinder medium temp 404
Sounds like you’re from Pittsburgh that’s the way we talk lol
I heard that from someone not to long ago, back n da day the traveling settlers likely passed through your area on there way to my area, ran out of pony power landed here and brought the "proper" English with them 😂
@@HVACRSurvival I hear ya. I use to catch heck when I went in the military in 1976 for the way I talked lol
@@redeye2629 Chuck I was 1 in 76🤣
what leak detector is that one ?

hmm wonder why they didint run all the copper for those evaps above the box and Tee them in up there adnd just run the lines top down rather than having all those hangers and copper inside the box.
Don't know, they have there own way of doing thing's I guess.
Trigger control? Didn't Prince make a song about that?
Yeah, it was spelled a little differently though😏
Only contactors that should not be operated manualy are older elevator one due to body choping possibility.
not really true, if there's a dead short and you closed it by hand standing in front of it? you're day could be very bad with major injuries, electrocution or just dead.
using an insulated screwdriver standing to the side with arm stretched over and back facing is the least dangerous way. some of us have had first hand close encounters with 480V, where the initial short circuit blew apart terminal lugs with a massive arc-flash and sustained an arc for 10+ seconds before a breaker opened (15 amp breaker at that).
while 10+ seconds doesn't seem very long. hearing it's like an eternity, when hearing it, feeling the heat and being blinded not knowing what blew or which way to move to get away. it's just not fun and seems like an year goes by.
True👍👍😎
so thats Wharsh and Poosh?
Both🤣🤣
#155 thumbs uP
Everyone makes fun of you for "warsh" and "poosh," but as the grandson of a French-Canadian, this is nothing new for me. My childhood was filled with "warsh," "wartch," "pellow," "agayne," and of course the ubiquitous "eh."
Those all look like words I use. What's wrong with pellow🤣🤣👍👍
16:47 cockroach?
I didn't notice any.
That place is a full time job, where to stop?
Not that bad, I just kept getting there late in the day.
Sounds like you’re from Pittsburgh lol
Ohio
Oh yes I know where he’s from. Actually not far at all
You mean warsh not wash
Yep, warsh🤣😁
I started to tease you about the snow, but I stopped. Don't want to be mean...
It came for one day then was gone by the end of the day.
