Replacing Capillary Tube On Reach In Cooler
HTML-код
- Опубликовано: 22 дек 2019
- Part 2. I found a restricted capillary tube on the first trip out for a warm cooler. I return this trip and replace the cap tube and restart the system after doing a triple evacuation as a result of having a steady rise on my evacuation blank off test.
I will also show why the Testo 550 digital manifold gauge set is a cheap Chinese knockoff of the high-quality Testo 557 gauges and not worth cutting corners on. Buyer beware. I emailed Testo about my issues with the Testo 550s again because my 557s went bad, after finding out that the 557 we're going to cost more than half of what they are new to repair, I found it's not worth repairing and when combining that with the dissatisfaction of the 550s that are brand-new looking, I am very disappointed in their response. I got no response... Thanks for the great customer service Testo USA...

One the things I covered when I taught class at the union and spent time at our wholesale counter was to show techs how to figure the additional refrigerant needed when replacing a pencil drier with a 032 cap-t drier. By doing a ratio by comparing the volume of the two driers ( pie x r squared x length )and adding the difference . I had a whole presentation just on cap tube systems.The Sporlan drier tells the liquid holding volume of different refrigerants on box. I’m sure it wasn’t exactly accurate but it got the guys close enough where the units worked I never had a complaint in all the 30 plus years I did it. Now that I’m retired after 37 years I enjoy your videos very much you do great work keep it up !!👍
Thanks so much Gary! I appreciate that👍👍. Merry Christmas!
Great video Rick- I like the way you edited everything, made it nice and smooth and still educated us on what was going on along the way
Thanks Bill, I might try doing it a little bit more like this, maybe not quite as fast transition, but vocal overdubs or voice overs as they call them is how a lot of people make videos. Plus there's always the benefit of not having two stop and explain things while you're doing the job. It's definitely going to take some practice, I've always been into videography but never quite to the production value that I would like to see. I'm trying to get my audio mixer to work with my computer. I have a QU-SB 16 channel Allen & Heath digital mixer that is massive over kill for video. But then again... you just seen me use two three-quarter inch vacuum hoses on quarter inch refrigeration lines 😁 who knows what's Overkill kill is in this field🤣🤣🤣
Love to watch your videos...Merry Christmas
Merry Christmas Rick and family!
Thanks Nathan! Merry Christmas to you and your family as well. 👍👍👍
it’s all the little details that add up to a good job. the kinda job every customer wants and young techs often aspire to duplicate. you know, the guys only a few years in who try not to miss a detail as they watch with great fascination and aspiration in hopes of one day becoming labeled a super tech. :)
All we can do is our best.
You helped me do a reach in cap tube thank you!!!
Awesome👍👍🤜🤛 thanks for the feedback!
Happy new years
Good job. 💪
You're the man! Thanks so much for everything. Very in depth and perfect for journeymen trying to learn. Cannot thank you enough. If you could just maybe slow it down a touch when you're explaing procedures
Are you having problems understanding what I'm saying because I'm saying it so quickly?
@@HVACRSurvival @1:16 to @2:30 you go through this fast I think because you've done it a million times but I had to watch it a few times to know exactly what types of tools you had and how you were operating them. Do you just heat up the old cap tube when removing it on the evap coil side? What psi do you pressurize the system with nitrogen for leak test? (Typically on the residential a/c systems we go to 300psi but that seems high for this) what micron level are you trying to reach? (For us we want 500). Seeing the fitting for the cap tube on the evap side for removal would be killer!
And of course thank you very much for the reply! I'm a residential HVAC tech in NH but and venturing out on my own on the side mostly In coolers like this! Very eager and love all the content! This makes me feel ahead of the game !
@@sleepnumber6ok... I made that video a while ago, that was one of the few that I did a voiceover narration. I made it really snappy because I hate people that have videos that drag on forever and show me stupid things that I don't really want to know nothing about. I don't need know when people go to the bathroom or where they go get their coffee at that's just a waste of my time 🤣, so I try not to do that to my viewers. To answer your questions, I usually heat up my base metal meaning the coil side first and wait till it becomes soft then I pull the capillary tube out. microns are microns you're supposed to stay under 500, do I always get that, no especially when compressors had refrigerant in it. Inside the cooler it should tell you what the test pressure is, generally it's like 150 lb but I've never had a problem doing it as high as 250. Supposedly you can blow the terminals out of the compressor if you make it too high. One word of caution... I would say if you're just getting into refrigeration and doing it on your own, you got to keep in mind they may have a lot of money in that cooler or freezer and if you make a mistake they're going to probably come after you for the cost of the food that gets spoiled if things don't work out. Just thought I'd throw that out there. Thanks 4 checking out my channel. 👍👍
@@HVACRSurvival sorry about that I should have know haha, will check that out for sure. Thanks again for taking the time to respond the trade community is really awesome. I've just been sticking to cleaning coils for maintenance. This exact job on a different reach in (2glass doors)... When I stuck my gauges on the suction pressure was like in a vacuum, warm filter drier and cool lines off the compressor. Pretty sure the cap tube is the culprit. (Already Cleaned the originally plugged solid condensing coil) wish me luck!
Great video!! Interesting
Thanks HVACR TECH!
Those True units always have a lower suction pressure. I called tech support and they would always tell me in the coolers they could go as low as 8 pounds in which I thought was a little low on r134a. A very good video tho!
I haven't even considered showing the video I just made where everything went to shit and was pulling zero. I had a bad day on Friday. Cut the capillary tubes apart three times verifying that it was not restricted from my doings. Still not a hundred percent sure what the full problem was but it worked when done....several hours over my quoted time. 🤦♂️
I’m an industrial sparky not an HVACR Tech, but I learned automotive AC in college (R-12 don’t laugh I’m old 👨🏻🦳😆) so I feel your pain - I still do some automotive AC work and follow you and Chris, Bill, Bryan... Anyway, I digress 😋
Bad test equipment is a big bummer - I’m glad to hear from folks like you - I try to always buy tools that are *_the best value_*
For electrical diagnostics I use both my old first gen FLUKE 87 (A Fluke 87-dash nothing for you young kids lol - my meter has more experience than yer mom 😘) and my Klein CL800 (also old like me ) so I tend to buy a good tool and hang on to it.
Maybe I’m just thrifty lol 🤷🏻♂️
When I upgrade from my old Mac Tools manifold I think I’ll go with Fieldpiece 😉
Great video bud 👍🏼
I'm no spring chicken. I started when I was 19 so I've been at this 24 + years lol I had a set of Testo 557 I just stop reading temperature on the suction side while making a video 👎👎which were awesome, but the cost to repair them was over half the cost of buying new and they're getting to be 5 years old so I don't really want to spend that much to repair them. So I need to decide if I want to spend that kind of money again or just use what I have because I also have the Fieldpiece probes which are excellent but not always as quick as I would like to see it.
I know what you're talkin about far as the fluke 87 - nothing I was in electronics prior to this and was what I was supposed to go into for college. So to say the least I really do like top-of-the-line toys. I own the Fluke 87 - 5, Fluke 376FC with the flex probe, Fluke 117, 112, Amprobe nav-52, and several other meters. Im a tool slut that likes nice things. 😁👍👍 I appreciate you taking the time to watch the videos my friend, have a great Christmas and happy New Year.!!!!
Sinister Sparky I get what you’re saying lol. I still have my Simpson 260 and yes it still works.
EXCELLENT VIDEO maestro :)
Thank you!👍👍
thank you for upload good video Sir
Awesome video. Question for you. I have ice building up around the entrance of my freezers evaporator. I vacuumed it down twice now, and refilled with the proper amount. The evaporator is still frosting but only for the first 10" of tube. The rest of the evaporator is shiny. Any ideas?
Could be a restricted capillary tube if your recharging it to spec and it’s pulling into a vacuum or has lower suction pressure.
@@HVACRSurvival I saw where someone isolated then flushed the tube with nitrogen, then acetone, then nitrogen again. Might try that. Guess I got some work to do. Might flush or replace the evaporator as well. It's r134 and it is in a vacuum on the suction side with proper charge.
Where did you get your blue marker can't find any that mark as well as that blue.
Also I only buy Fieldpeice took set of 360 in about a week ago dropped broke the screen and they gave me a rebuilt or new not sure but they look new no ? ask no charge
Fieldpiece is great at taking care of the customers👍👍unlike Testo. Look in the description area, I have links all the tools I use. It's locaited in one of my kits.
Thanks for great video again. Have a question. Is it just me or just happens to someone else as well, when ever i change cappilary tube i tend to add ounce or two more then is factory labeled. Maybe is because of dryer but literally always end up adding bit more to have satisfied operation. Cheers
I have It happen to me often, and some of the driers are possible larger than the original one likely causing that.
what great gauges, only the finest chinesium with number creep.
probably like tire and other gauges I've had, they suck the battery down fast and don't compensate for voltage drop, I found one tire gauge with weak battery skewing over 15PSI by time you checked four tires!
Nice job
Thanks lance!
My 557’s have been great to me. Sometimes I have use the heat and beat method to dislodge crap outa the oil in the hermetic compressors so I’m not there all day.
I have no complaints on the 557s, I just don't want to spend the money again on them. So I stick with these cheap 550s and bitch about them not zeroing out. LOL
I have a small 12v fridge. Compressor kicks on , thermistor reads accurately and thermostat works. Capillary tube gets ice cold but fridge stays hot. Does that sound like a capillary tube blockage ?
If it's cycling off and on and holding temp, I wouldn't worry about it. Cap tubes can play games with you. If it's not cycling, I would add a suction port and see what the pressure is.
HVACR Survival The fridge stays hot. There is no cooling inside of it. This type of fridge doesn’t have a fan to blow cold air inside the fridge compartment. The compressor stays running all the time. What do you think ?
It's possible it's restricted, without knowing what this looks like and where it's being used it's hard to be sure. I would turn it off until you can be sure, otherwise your possibly causing more damage to the compressor by letting it run.
My testos do the same thing! Thought about buying the yellow jackets but scared of the touchscreen for longevity
exactly, a touch screen to me just doesn't seem to have a place in our rough and tough field. If you drop that thing one time face down and crack.. it's gone🤦♂️
I found a restricted capillary tube on a unit. Looks like they threw out the entire thing because they didn't want to repair it. I've measured the capillary tube and it appears to be .143"-.145" outside diameter. Is there a slightly larger size capillary tube I could use to slip over each end after I've cut out the damaged section to braze it back together? Thanks!
You can use a piece of quarter inch copper, Crimp down the ends and then crimp it shut. When sizing a cap tube focus on the inside diameter. JB tools sells a sizing tool and they sell the cap tubes
@@HVACRSurvival Great Idea. Do you know what the name of the tool is? I searched and couldn't find it. (yet) I have a homemade tool I made for rolling tubes into a smaller diameter. It's basically a pipe cutting tool that I've ground the cutting wheel down until it's a wheel like the others, so instead of cutting, it "rolls" the material thinner. I'll try my homemade tool first after annealing the copper tubing and see if it works while I wait on your reply. Thanks for the response in advance!
The tool I'm talking about that determines what size the cap tube is, is made by JB
@@HVACRSurvival Oh ok, no problem. I have a pair of calipers that I use to measure the diameter. It's accurate to .001", so I'm good.
I used my homemade tool. It worked great! I used a gauge pin inserted in the capillary tube to prevent my tool from rolling the tubing to a smaller diameter. Works a treat!
I worked on a similar reach-in that had a blocked cap tube. I changed it out along with a new strainer, and suspected it was something with the oil. Was working fine for 3 months, then the same problem again. How can you prevent it from occurring over and over?
dump the oil and replace it with new. That has worked great so far,
Good luck, I remember changing it out several times with mixed results. This happens because a capped cap tube=a burn out usually with these units. No acid removal HH filter driers in this size further limits actions.
I now replace the oil in the compressor when there's a chance the oil has broke down to prevent the new cap tube from plugging up.
what filter dryer you use on video
Sporlan 032 cap T
Did you change evap fan motor? Common problem on true coolers. Oil leak and slow rpm.
Noted it on my paperwork and spoke with staff, have not heard if they approved it yet.
My 550's do the same thing. Good vid.
No kidding, so we'll they were right, it wasn't worth sending them back. My Testo 557s never did this crap but they also were a lot more money
@@HVACRSurvival as long as I zero them before I put vacuum or pressure on them they have always been accurate to any other gauge I compare them to. I get that same bad feeling though after working on something and watching it read vacuum when you take it off.
@@HVACRSurvival haha my field piece probes have been doing the same thing last couple days. They will be zeroed out when I start and when I take them off they will read negative a couple psi. Weird.
@@jonnymac31 I hate to say it too but Fieldpiece probes have started doing it to. I guess what do you expect for 500 plus dollars🤣
You have to cut the cap tube to length right?
Yes absolutely, we call the factory and ask what diameter and length they need to be. This particular one was required to be 12 foot at the diameter that I had (It's based on the inside diameter.) Great question👍👍
Agree on the testo manifold👍
I really liked my Testo 557 but they just broke and they wanted half the cost of new to repair. The 550s are garbage. I haven't used them in 3 years, and I just let it go until now and I hate them.
Great video and I am so glad I did not buy Testo gauges
Are you swedging with a M12 impact, by chance? I thought they required a higher RPM than that drill requires. If it works I would be STOKED.
Yeah because it was quarter inch, it might even do 3/8 possibly half-inch but anything bigger than that you're going to need a 18 volt
@@HVACRSurvival My ancient M18 Fuel has a slippeed chuck from serious abuse. I paid a ton for it 5 years ago when it was new. Need the boss to pay out. Thanks!
@@analogmoz I've never worked anywhere that doesn't have a tool replacement program or at least a tool expense account. That would suck.
How does one check cap tubes for restriction
If I have any doubts I will pull the full charge out and weigh it in. If my suction is low then I have a restriction.
You indicated that the pressures on the 550 did not show zero when the lines were disconnected. Didn't the zero function work? When I work on a system I always make sure my gages are zeroed first, if not, bleed the lines then press zero. If that doesn't work, yes, you have a problem with your 550. I've only had to contact them once about my valves leaking, I purchased a set of O rings plus spare valve stems.
Jim
I will zero them and they will be off again when I unhook, I spoke with the factory and its because they use a cheaper sensor than they did in the 557. Sometimes they go back to zero and lots of times they don't. There cheap China tools, not German like the original ones were, you got what you paid 4 I guess.
How long did it take you
I think 3-4 hours because the extreme vacuum time I had, even with those large hoses. That's why there not over kill when pulling on a system that was open because of a leak.
Great video True's got to be one of the worst cooler's out there
Turbo air is the worst, I'm not a big fan of a few others. But True is better than a lot of them.
👍👍
how did you know that the capillary is not good
Watch the 1st video, the link is in the beginning of the video.
Next time heat the oil! Take a torch and heat the outside of the compressor?
#65 thumbs up
Too bad I was gonna buy me some testos.
Guess I'll just stay with ol trusty analogs.
Cant beat doing math😁🤔
I loved my Testo 557s but they just broke last week and then they wanted $200 for the control board Plus I needed a new temp sensor And there was also labor. Basically a little over half the cost of new. Now that they're screwed up I'm stuck using the 550 S. The 550s are garbage. I really like my Fieldpiece probe. But I don't know if I like the sman manifold. They're just so large
Yea I feel ya on that..sucks to invest in a tool that let's u down..
I've been researching the testo and fieldpiece manifold guages. Testo has a 2 year warranty where fieldpiece has a 1 year warranty. How long did you have the testo 557 before it failed?
@@whitesheatingairappliancer7101 The 557 had some small issues that were taken care of under warranty and I think they only had two or three year warranty now they're offering five, 550 series is ther shit series, the 557 is there good stuff, it just pisses me off the repair of the 557 was 1/2 the cost of new. So I sold them on Ebay for parts.
@@whitesheatingairappliancer7101 also Ron, Fieldpiece usually will do the repair for free even if it's out of warranty.
I sent you an email regarding one of your tools
Thanks, I will take a look and get back to you👍👍
Teso had some good equipment in early 2000, but no one wanted to pay for that level of quality and now their junk. Just like every other manufacturer, just moving boxes.
You should try over sizing your cap tube !!!
I shouldn't have to re-engineer something that was already designed and worked all these years. Plus I was out in the middle of nowhere without access to any additional parts.
my testo 550 clamp probes were 8-10 degrees off. totally unreliable.
Are you comparing that to ice water? If so, there’s a compensation you’re gonna need to turn off.
testo does not impress me
I liked my 557 s but they broke so I'm stuck with these turds for now until I buy something else.
