This channel is centered around Industrial and Commercial Refrigeration Service Repairs. but occasionally I will drop a video around other useful knowledge I have from years of learning. I have been doing HVAC work for 23 years, as my only career path. Inspired and taught by my father, I started as a Residential Installer at age 16, with a thorough understanding of 240V Single Phase Home Electrical, Automotive Troubleshooting and Diagnostics and many other things under my belt. By age 18 I was independently running residential service calls for Houston Homeowners, averaging 5 calls per work day for the next 14 years. Since 2015, I've been Commercial Refrigeration. I never hire people to do repairs for me. I learn, and through trial and error, do better work than anybody I could hire. Here, I share what I knew in a way you can understand

Dirtiest Condenser I've Seen Lately
YT272
This video shows when I was washing a condenser coil on a rack service call that was for a blown discharge line, that ruptured likely from running too high of pressure because of this dirty coil.
Let me know what you think about how dirty it is.
Have you seen and washed out dirtier coils?

Oh god, i thought that was one i replaced 😅 i did a motor just like that for a different customer and the wiring was something i had to be extremely careful with because the previous motor failed because of incorrect wiring.
@@I_Lucid_Dreamer do you work at the same place I do?
Ive come across dirty condensers and evaporators all my life which as you have stated is the most common cause of failures...and no one cares 😢
What are you guys using to convert R-22 medium temp racks What refrigerant? I have someone asking me I told him to consult the rack manufacturer Figured you have seen some conversion Thanks stay cool out there HTown is smoking hot today
You need some new analogs bro. Put one on a PO
@@TheGhettoLobster yea, i know. They're only $18 each. No excuse for it
I've thought about a yard sprinkler under the coil that's controlled by a solenoid and set for a period of time depending on the wind/ weather. Running it constantly could slug the compressor or some shit when it's cooler.
@@1776cootsflybynight I actually did that a couple places last year because of how hot it was. It's the only way I can keep them to maintain. you can get a timer at the Home Depot for about 40 bucks. I get it to come on at about 2:00 p.m. and it would shut off at like 9:00 p.m. as long as nobody messed with it and nobody turned off the water

Hello, MASTER TECHNICIAN MINDSET-How are you?? Hope you are well, recently I have looked to your channel. And saw that in your channel have many many problems, for this reason channel videos not getting much engagements. Not growing, If you can solve these problems, channel will grow, You want to know these main main problems??? I can tell if you want to know. here or in email!! Where?????
that UI is very cool. Wonder what it was written in and what kind of CPU is running all that UI and control logic....
@@revealingfacts4all i dont know. But its an interesting observation, and it agree. Now you have me wondering. If its E2 Controller by Emerson, in case you want to research it
Spot on always very informative and helpfull 👍
Excellent as always and a big thank you 👍
Is the filter/drier plugged? I've seen them start coming apart inside with age. With all the effort personally I'd throw a $20 NOS R22 txv on there. Even after the new cap tubes you're are still at a CR of 4.3, really should be under 3.
yes very good point. under 3 is what I need to make it
? Did you need to purge nitrogen while brazing
go full honky and chuck in an internally equalized tx valve!!
Man this brings back memories . I started working on these and domestic refrigerators over forty seven years ago and worked my way up before retirement.
@czechmate6916 wow. That's a long time ago my friend. Hats off to you!
Restricted cap tube. Also you need to nitrogen sweeping (shielding gas). Fixed meter system should not operate with much if any subcool. Superheat is based on wetbulb indoor and drybulb outdoor temp. TXV is what you pay attention to subcool on.
@hvachacker586 yea, I'm familiar with the exact technicalities of the industry standards and best practices. I've worked with them for such a long time that I understand more about how the refrigerant is flowing through the circuit. Yes, wet bulb and in/out dry bulb are relevant when applying textbook precise readings, but subcool is also still relevant on a fixed metering device. Having subcool only means that liquid change has been completed. If you don't have much, or worse-if you don't have any Subcool, than you don't have a full column of liquid. If you have 0 subcool at a ground located condenser, than you for sure are boiling off on the vertical line set to the evaporator. We also charge txv systems by subcool, yes, but the TXV only serves one purpose: to maintain a preset superheat. So superheat is equally relevant on TXV systems.
Every refrigeration system has to operate with some degree of subcooling, without it you don't get phase change in the evaporator.
Wow
58:30 brother QUESTION PLEASE, I wish u kept the camera at that paper a little longer, i can screenshot and see the sequence but how tight should we screw all those different 7/8/10 bolts? Is there torque specs? Would appreciate if u answered, stuck at this part now
@@jamesethan3749 yea, give me just a min to find them
@jamesethan3749 click on the link below. It should ask you to download a 108 Page PDF file. That file is the actual ATSB Service Manual. Page 108 has all your Torque Specs. Let me know if for some reason you can't download the file.And I'll figure out another way to get the information to you atoc.ru/uploads/manual/5fb79aebb40df.pdf

@@mastertechnicianmindset2181 if you link it in description for future people it would be a life saver. I spent SO MUCH time rewinding your video and trying to take screenshots and most were still blurry 😅😅😅 wish i had this at the start of my rebuild journey, but better late than never!
@@jamesethan3749 ill do that
Next time pressurize the compressor then you can move the oil to the suction header. This way is less messy
Would love to see this done on a 24 tooth reluctor
Packing nut!!
I applaud 👏 you sir. I would never try this.
Can you do a van Tour?!
Well, I don't drive a van these days. It's just a utility body single cab truck. I could probably do one soon tho if you want
Great job brother. I’m going to have to check and see why I wasn’t notified of this video and the one before it. I will watch it later. I’ve been seeing comments on other channels where people aren’t getting notifications from UA-cam and some had re subscribe because they got unsubscribed by UA-cam. I just thought I would share this with you in case you noticed views are down.
@czechmate6916 thanks for that info. I'll keep an eye out
Good job 👍
I tried applying as an apprentice at Hussmann where I am I haven’t heard anything from them yet I want to get into supermarket refrigeration but I can’t figure out where to start
Hussmann is not the only super market refrigeration company.
@@juan251100 where I am they are
Yea, some remote rural areas I'm sure they're the only ones
@@mastertechnicianmindset2181 they told me that I need prior refrigeration experience and that I am not old enough don’t know if I believe that though because I know you mentioned that you had an apprentice
Learn everything you can. You know what makes a good technician? Someone who reads the manual. Those little pieces of paper in your sporlan power head? Those. Read them. Hussmann tech from Atlanta GA. Speaking from experience. Go to community colleges. We are TAs there... and we are looking for you there. Trust me on this one, we see who's got it and who's a sh*thead... get through those classes and we will find YOU. 5 star, Mollenberg and Betz. Frick. Hussmann. All of us are looking.
If you’re in Houston you should come work for the Arcticom group where hiring!
@@bigredyt9563 I would like to. Tell me more
Lowkey shoulda pumped out the oil first
Gotta love protocol racks 😂
You could just put 134 right in that system no problems I know from experience because I have done it a couple times the first one I did it on it’s been 2 years and that system is still working
Mask is a good idea as well if your sprayer delivers a fine mist. I tend to mix my cleaner at a heavier concentration on heavy buildups.
@davejohnsonnola1536 i do too. And yes absolutely a mask for a fine misty spray.
No copyright infringement on musica ranchera!
Lol, but they do. I have to chop all the songs up. Every 3 seconds, I cut out about 0.1 seconds from it, and this seems to do the trick
That’s the sound a flaker makes when it’s making ice with cleaner. The cleaner turns to slush and makes the gear motor pull high amps. Flush the cleaner out and then start it up again. Should run fine. Edit: I spoke too soon. Didn’t see you wiggle the top to show the bad bearings. It’s done.
Lol
That noise was horrible. Crazy what happens when bearings wear out. I've never worked on one this style of ice machines, but it seems interesting.
@bradmironik6137 I agree. That is one of the worst ones I've came across. What's stupid is that this machine has been warning them about this for a long time. When the scale builds up, it overamps and trips with a code 2. Probably also had the Descale light on. So, instead of getting it cleaned and acting on the Red Light, and calling for service to clean it, they just reset it. Over and over again. And when they finally did decide to call for service, if they had a good tech who recommended cleaning, the store just said, no, maybe next time. SMH, that's what they get
i hate flakers
Do you really? I like them. Once upon a time, I was apprehensive when I knew that my service call that I was headed to was one of those. Like back in 2020, where I was working had the Sonic Drive Up Account, and everytime i.got an Ice Machine call there, I knew. These days, I think I would rather actually work on.one of those than on a crescent or half dice cuber.....
@@mastertechnicianmindset2181 yeah ive had too many callbacks, i dont like gearboxes and bearings and water seals and all that crap
Getting some nasty 💩out of there. I’m only asking because I never did any automatic transmission work. Couldn’t you have used some Rx11 flush?? This seems to be working pretty good I just thought maybe the other way might be easier idk. Have you got your power restored yet?? I hope you have.🤞🤞
@czechmate6916 I would imagine that, yea, I could've used Rx11 Flush. I even have some in my garage. The thought never even crossed my mind, lol. Yes we did get the power back. Every time.it rains here the power goes out almost. This last outage though was pretty tough.

Good video bro. Yeah that unit is toasted
Thanks. I try to keep them as informative as possible. It's not the easiest or the kind of thing that only takes little time. Lol
Please send to me anther video when you replacement the evaporator. Thank you.
@@maheradous9257 if we do an Evaporator, instead of a replacement, I for sure will
Very good 👍 job
Sad lack of maintenance
Yes. That is all that this is. Why would a business pay over $10,000 on a machine, just to neglect it completely when it's in your store...
Thanks so much for the link man! I searched “6L80 techm clean” all over UA-cam and the bastards hid it from me! It was buried down. I did buy the kit to install the pressure switches easier and correctly, the last minute of this vid is exactly what I wanted!!!! To see if its OK to clean it real good. You are awesome man THANK YOU!!!! ❤️❤️❤️
@jamesethan3749 cool man. No problem. Let me know if you need anything else. Can't rush the transmission rebuild. And gotta make sure everything's right. I even flushed the transmission cooler and the cooler lines with mineral spirits then chased it with compressed air, both directions, twice. Then primed it with new fluid. Did the same with all the crevices of the TEHCM. My rebuild has been fine, going on probably 35000 miles now. Good luck!
i know what happened. you probably searched for TECHM, instead of TEHCM.
Finally an excuse to straight pipe the truck lol
Thanks for the video, it helped me a lot to remove the transmission.
@@ukuseukuse6611 that's awesome! I'm so glad you told me. Thanks
Now you just got to rebuild it LOL Taking it out's the easiest part!😎
14:47 you must have a death wish to get underneath like that.
@papi9196 it's not going anywhere, and even if it did, the wheels are still mounted and it would have to crumble the bricks entirely for it to actually hurt me. But with the bricks the way they are, it's stable
California sucks they’ll arrest us for having one instead of the crackys 😢
@@alejandrozometa1951 yea, f$ck all that man.
Did you rebuild the clutches or just cleaned the valve body?
@MatthewDannevik I did replace all the clutch packs. I soaked them in new fluid overnight and even tested the pistons with compressed air through the ports that connect to the valve body. I have a lot of other footage from the rest of the build that I need to find the time to upload.
Hey i need ur help
@@p8456 what's up
No vacuum needed?
@laginbro well, what kind of a vacuum? And, at the expense of what? We have to weigh the pros and cons differently as it relates to supermarket stocked cold cases where time is of major importance. On say, a 3 ton split residential circuit, where replacing a 163s drier could account for a large percentage being introduced into the circuit, possible 1%, 2%, 3% etc...(and im just making up numbers here, by the way, for the sake of the discussion), I would think that Yes , removing that two or three percent of non condensable gas out of the circuit before mixing it all up by starting it is critical and cannot be skipped. As it relates to a rack circuit, and the amount of volume inside that little piece of 3/8 pipe, In comparison with, let's just say for now, the circuit by itself, circuit 2B. We are way below 1%. Possibly below 0.1%. .But we also have to take into account that there's the rest of the rack with hundreds of pounds of refrigerant. I introduced perhaps 0.0001 non condensate volume to that rack, with huge Liquid Filter drier. I am not really willing to risk all of the food that's in that circuit, and in that case on that aisle for such a minor amount of non condensable. Maybe this approach is wrong , but it's just my way of doing it. Also, At 2 o'clock in the morning. I don't want to sit there and spend another 45 minutes pulling a vacuum. But if it was a large percentage of Jon condensable like if I was replacing an evaporator, I would never skip a vacuum
Since you eliminated the 2 driers out of the circuit, are there means to filter the refrigerant system? Also, what size/type of brazing tip do you use? Learning thru your point of view.
@bradmironik6137 yes, there is actually large liquid line Drier cores for the entire rack, that are located on the liquid line just out of the receiver. Additionally, these TXVs have serviceable screens that will catch small particles before they enter the txvs
@mastertechnicianmindset2181 Thank you for replying.
Nice work master tech.
👍👍
