Randell maketable not cooling

Today I show you why we need to replace all 3 evap coils on this Randell maketable. I go through the entire process of un brazing all the old parts and rebuilding and installing the new evaps, thermostat, new drier and of course added new refrigerant.
Today I finally had time to cut open the compressor that was murdered by an improperly placed filter drier. Enjoy

I've been in the trade for 35+ years. Even an old guy like me can learn something new. Pay attention to this young man. I like his approach and thought process. Our trade has too many parts changers. It's important see the big picture and properly diagnose the issues at hand.

[@michaelszczys8316]

Could have gotten in this trade but never did. Still learning a lot of this stuff anyway after 45 years. I don’t know if I’ll ever use it except for car systems but like to learn anyway.

[@HumanRightsRevolutin]

Chris's video are great but I find yours more helpful for us newbies. TYVM please keep them coming

[@Dave-dr4yy]

Great video! Purchasing a new Randell is a small fortune so I can understand your customers viewpoint.

[@ronaldzeigler9057]

I love this stuff I did a lot of refs. Did cascade systems in hospitals.loved it retired now but I enjoy your show .

[@curioushvacguy6876]

Thanks Ron-

Next time you are scrapping a old condensing unit.. Take the condenser out, with fan and wiring.. Then put a scherder valve on the inlet and outlet of the condenser.. Put it between your tank and recovering unit.. Remember to plug in the fan on the condenser.. And now your tank won't get so hot... Make a little Fram for the condenser and a socket on the wiring for the fan... Because when it looks good and cool, you get street cred😎👍😊 The condenser on this unit is perfect for the job.. Maybe put in a more powerful fan if needed

[@jerrypinault1573]

Wow!! Sweet idea!!

[@christiansommer914]

@@curioushvacguy6876 cool. But you will lose some refrigent if your recovery unit can't purge..

[@Randylazz]

You make it look so easy........Nice Repair

Great vid. Changed out the reachin evap in same make table about year ago for leaks. Great work bill!

[@dumptrks]

Thanks for the in-depth detail ...Great Video as always

found your site this week, love your videos.

[@curioushvacguy6876]

Awesome! Thank you!

[@adammiller2246]

Oh, these are a lot of fun to change out! (being sarcastic) . Have fun, better you than me.

[@jamestoy426]

Nice job but one question don’t you worry about metal shavings getting into the compressor? I was taught to always use a tubing cutter

[@johntorcomian5223]

Another great video! You have so much patience lol

[@stevengilber1153]

Great video as all you've made have been. On this one I thought that you said this makeup table was R134a

[@imwojo]

Not a HVAC-R guy but I have a question. Nitrogen is used to prevent carbon flakes forming inside the copper right? Is this not a critical thing or only happens in closed lines? I noticed that no nitrogen was flowing on the bottom evap coil and the solenoid was not open with a magnet. Not finger pointing, genuinely curious.

[@jameslippincott]

Pizza Hut uses those exact tables...so much fun!

[@JCM2LA]

Very good video thanks for sharing

[@mel904]

Tight spots like that I always used Staybright on refrigerant Controls.

[@davejohnsonnola2758]

I've been using Staybrite on all my small reach in equipment. First with my ancient Prestolite mapp gas torch handle and more recently with an air acetylene turbo torch. Like the lower temps and no nitrogen needed but working in tight spots have had some collateral damage from the big flames and now want to experiment with oxy acetylene. Most of what I work on is 1/4" liquid and 3/8" suction. What size oxy-acetylene tips do you use especially in close quarters?ķ

[@davejohnsonnola2758]

@@curioushvacguy6876 have looked at the smaller Smith jewelers torches as I've had personal calls on some high end residential units.

[@whitesheatingairappliancer7101]

It seems that using a torch is going to be obsolete? Everything switching over to Vulcan locring fittings.

[@momon1828]

Randell is gold and never put filter on condenser it was never meant to be

Great video!! Do you know about the pressure test feature of the Testo 550? Hit the mode button to get there. Keep them coming. Learning alot. Thanks for posting.

Nice work

[@curioushvacguy6876]

Thanks

[@georgebrabec1749]

Question, when you were recovering the system charge, you said the charge was R-134a, When you were charging the system you were pitting in R-404 ?

[@jimbola77]

dang partner u r good!!!! I wish I had your knowledge.

[@rocker8692]

You would think we could make coils that dont leak by now,but what fun would that be.

[@ronaldzeigler9057]

Love the nitro use not every one does that to bad.

[@curioushvacguy6876]

Thanks-- you gotta use nitro whenever physically possible, keep that carbon out of the lines

[@DW-bo3qw]

Pizza Hut? Lol gotta love those randell units

[@DW-bo3qw]

Agreed i don’t mind working on them but it does seem like they leak quite a bit

Nice orange magnet

[@hvac01453]

blowing through copper pipe is common on oxygen/acetelene, lots of guys will use turbo torches to prevent that. I've done it myself. I never lug all that shit around anymore, it turbo and an MC for me. You mentioned sensing bulbs for the rails... Is there more than one metering device, and sov ?

[@curioushvacguy6876]

Hey HVAC01453- interesting, I used to use a turbo torch exclusively but had issues getting txvs brazed in, maybe due to low heat or me not doing something right-- so I switched. On this particular unit there is a TXV in the lower evap, and one TXV for each rail up top. There fun little units to work on, even better if your not trying to do all that while there open and stepping all over you. Thanks for the feedback

[@hvac01453]

@@curioushvacguy6876 If Im doing a brass distributor head or large TXV I use oxygen/acet to try heat it up quickly. I like to disassemble parts when possible to prevent damaging seals like teflon or O rings....a power head... I sometimes switch to solder in an attempt to try limit the heat applied.

[@obedb093]

what should the superheat be in these units?

[@IFIXCASTLES]

A lot of work!

[@curioushvacguy6876]

Yeah, it wasnt to bad though since I was able to take it outside next to my van, made the day a little smoother

Do you use the white flux ?

Not on these, have you?

Dope man. I was eating pizza watching this lol.

Yes, as well as the wet rag playdough like stuff

What refrigerants do you carry around with you on a daily basis to cover all your jobs?

normally r22, r404, 134, and 410

[@mtucker3401]

I would have cleaned the copper before cutting it. Just my thoughts

[@lewiemcneely9143]

I might as well subscribe and be done with it. I LIKE what you do and how you do it and tell about it but the goofy part is I'm a mostly retired and retarded truck driver and equipment operator and the only thing I've ever done in these lines is change a bulb in a cooler, clean the dust bunnies out of the coils and build an ice shield over our heat pump outside unit. So if you won't run me off for not being a member of the club I'd really like to tag along. And I used to be fur faced but it's easier for me to keep it ground off these days.

Heck yeah man, the more the merrier

The only concern with Turbo torch is to use hearing protection while brazing, it also seems to calm me down using hearing protection also.....

[@curioushvacguy6876]

I've never tried that-- I might have to give throw some ear plugs in and see if that makes it easier--

[@hvac01453]

@@curioushvacguy6876 the only caution is that I once put down my torch without closing off the torch.... I put it down while on..... I didnt hear the flame go out as I was use to. I smelt the burn and couldn't believe what I had done. I'm cautious about that now.... Ive lost quite a bit of my hearing in my right ear now after 23years in the Army and about 28 years doing this....

It’s a silfos brazing rod, you know this, quit calling it solder, sorry, pet peeve.
