I love all the binders you keep with manuals for pretty much everything you work on. Me being a young engineer-to-be, I see a lot of peers of mine who think they can remember everything. I like how neat and organized you keep all your reference material, in a work van nonetheless. Always impressed with your skills and attention to detail.
Thanks for the information I’m starting to study for my HFO Certification and it’s good to see real world application Really appreciate all the videos! 👍👍
Thank you again for these types of videos. I just found a cooler with similar symptoms. Going to work on it today. Getting familiar with R-290 though. We'll see how it goes.
Just last weekend I worked on a Norlake unit. Last week on Thursday went out to replace the condenser coil the sheared off right at the tube sheet. Replaced it with new coil and did a normal vac and charge. Called back on Saturday for it not working again. Replaced the filter/dryer and revacuumed for 4 hours since the oil was not wanting to release the moisture that got into the system from the first problem. What a nightmare that was. Just goes and shows that the old vacuum by time does not always pay off.
Poe oil won't let go of the moisture with a vacuum, if I believe the oil is shot I'll dump it and put in new. Otherwise the cap tube will plug up and bite you in the butt.
I do a lot of True residential 24" under counter wine/ beverage centers with 134a, and I have found many of those grey colored evaps leaking where yours is and in the middle of the coil. The replacement coils are black in color, hopefully they hold up better. The build date on the coils that I see has been mostly 2017. Great video by the way!!!
Good catch Rick . Seems like that particular True model has lots of issues . Replaced module , on one of those , done hinges , gaskets , LED , and driver Geeezzzz True . One positive thing , they learned from Everest and Turbo Air on those easy to replace Cap tubes 🤷🏻♂️.
I thought I was doing something wrong with a lot of r290 freezers finding them with leaking Freon evap s and stopped up caps tubes , compressors being burned up blown compressors blown overloads great video brother
Thanks Doug, these R290 systems are built so efficiently that there's no tolerance for compressors that are low on refrigerant thanks to thin copper coils and they leak refrigerant in the evaporator then burn up the compressor. Another example of the government making things worse.
@@HVACRSurvival Some equipment use the DI, on the controller to sense a low suction pressure with a pressostat and safely stop compressor if tripped x'times in y'time. It could be an european thing.
I work on a lot of Trues and r290 in general. Where did you get that service manual to check the parameters? That would really be helpful to have in my rig.
Good video rick. Apparently evaporator coils don't last long no matter what refrigerant the manufacturer's are using. Not sure if this is just poor quality or the contents being stored in the boxes. Happy new year to you and stay warm.
Given True Manufacturing's history on their quality control, I would say that it's a quality issue, but since all the other imports have cheap evaporator coils, many being aluminum, the situation is unlikely to improve any time soon.
Just curious, do you make it a point to replace the cap tube when doing an evap? I’m thinking it maybe good practice. I started a new job where I’ll be doing a lot of these. Edit to say: the coils they’re using with these are not resilient-at all- I’ve done many.
Normally we replaced the capillary tube anytime we replace the evaporator. It’s a little bit of a pain in the butt but it reduces the possibility of a callback by a lot, now I will tell you if you have a system has been running low on refrigerant the next best thing you can also do is dump the oil out of the compressor and replace it with the same amount you took out, if that oil is compromised It’ll plug up the new capillary tube.
On there website and my personal notes while talking to them on the phone. Some of the abbreviations are not even in the book so I had to ask the guy on the phone.
Young tech hear Rick, I noticed after u added the new proper charge ,the evap temp was 20 and the stat said it was 54 degrees in the space ,as it is a reach in cooler 20 degrees td shouldn't your evap temp be closer to 34 degrees ?
From my experience the suction pressure will drop as the box temp drops but generally the saturated evaporator temperature will hold somewhere around 18° but sometimes as low as 12°. If you look up how a capillary tube system meters it's kind of interesting, as the temperature changes the flow changes. I'll have to look for the article, maybe I can do a video on it. I'll have to get refreshed on it because I forget all the science behind it. But what's interesting is there's no calculated means of determining the capillary tube size and refrigerant charge, the engineers literally have to build a system, test it's operation, cut it apart, adjust it over and over until they find what works. It was kind of interesting how it's not a calculated science but more of a ballpark until they actually run the test from what I read. I believe it was Supco who wrote what I'm referring to.
If ur gonna use a bucket and the same size cannister for it all the time, could always flip the bucket upside down and put a big enough hole in the bottom with a slit for the hose to go through.. Should be more stable that way if you dont have a proper stand.. shrug, just a thought..
Yeah, I can make one out of sheet metal but I really don't do that many of these (yet). This little bucket thing worked better than expected. Thanks for the suggestion 👍👍
I am seeing failures in this type off equipment all to often. Units that aren't even a couple of years old. Hopefully the industry will do something to make equipment last longer. It's not right for a customer to spend $7000 on a True manf.brand cooler and it not last but a couple of years. Very sad
I fully agree, but unfortunately voting has consequences. People vote in politicians that are bought off by lobbyists that tell them that global warming and all the other hoaxes are real so they come out with alternatives that just sell more products. just like there's no money in fixing the disease just continue treating the symptoms.
It didn't. (I didn't record me trying that) the pressure was to low for both devices to find it. Once I recharged it, I was able to pick it up with the leak detector. I never tried the ultrasonic a 2nd time.
What kind of cooler? I've got a few of them with regular mechanical controls that I've made videos of. Usually they're true two-door or three door coolers and freezers. If you search within my channel you should be able to find them
Hey Rick I have a stand for my R-290 cylinder.. It looks like this images.app.goo.gl/ww9Tukrefeew2hrh7 Its stable and works really well. You put a straight ball valve on your cylinder and screw in on the stand and then connect your horse to the valve on the stand.. Ohh and killer video

I try to keep my quick fact sheets condensed so I can quickly find my info. Thanks for the compliment and for watching👍👍
What a snowy day !! Rick you are the best !!
Nice job Rick! You always find the best and easiest solutions! That little bucket and scale is spot on, well done! Perfect shot of micro-leaks!
Thanks for checking it out!

Nice Video Rick👌🏻👏🏻👏🏻👏🏻 well spotted on finding the leak! I’m not looking forward to working with R290 units 👨🏼🔧🤦🏼♂️
I work at true im not surprised by this.
Lol. Nice 👍👍
The spot where I braze on the tap got repeated in finalizing the video? Computers Suck😂
Uyyy, itz fine, more videoz coming sir...
Another great production ... Thnx for posting ...
Just 4 you Eddy 👍👍
@@HVACRSurvival Lol ...
Great video as always!
Thanks again!
Great job
Rick Awesome find man those tiny ones are brutal... good catch
Thanks for taking the time to check it out 👍👍
Awesome job bro.😊
Good finding. Thank you.
Thank you!
Very good thanks
Thanks for checking it out!
Excellent job
Thank you!
Thank for the video & tricks rich have a good day 🤟🤟
Your welcome, thanks 4 the feedback 👍👍
awesome as usual.........great video

The new coil was made by Nordyne so we will see. I think of the poor quality equipment when I think of them.
Good one Rick 👍,
Thanks 4 watching Greg 👍
Another great video 👍👍👍
Thanks Harry 👍👍
Awesome upload. R290 taking over!
Nice one 😎
Thank you 👍
Good catch Rick . Seems like that particular True model has lots of issues . Replaced module , on one of those , done hinges , gaskets , LED , and driver Geeezzzz True . One positive thing , they learned from Everest and Turbo Air on those easy to replace Cap tubes 🤷🏻♂️.
They learn sometimes but they probably will change it back 😂

👍👍👍👍
These light colored epoxy coated evaps leak like crazy! I've changed like 20 of them.
Sounds like quality is job one 🙄😂
What's that scale
Nice 📹. ! Is evaporator getting replaced? Or just keep n eye 👁 on it?
Found out it was under warranty, they are sending a new one 👍👍

what brazing rod your use on this cooler? i saw you use matt gas

I hear ya 👍👍 Thanks 4 the feedback Brad 🤜🤛
Given True Manufacturing's history on their quality control, I would say that it's a quality issue, but since all the other imports have cheap evaporator coils, many being aluminum, the situation is unlikely to improve any time soon.
Which capillary do you use with the R290a for low temperature?
It depends on what the manufacturer tells us. We call them when we get the parts.
Just curious, do you make it a point to replace the cap tube when doing an evap? I’m thinking it maybe good practice. I started a new job where I’ll be doing a lot of these.
Edit to say: the coils they’re using with these are not resilient-at all- I’ve done many.

Hi were did you get that manual with the true controller
Www. Truemfg. Com
Damn where did you get that service literature? I always have to call the factory that would be amazing to have

Do you think R290a is more effective than R404a or R507?
It seems more efficient but isn't approved for large scale systems.
If ur gonna use a bucket and the same size cannister for it all the time, could always flip the bucket upside down and put a big enough hole in the bottom with a slit for the hose to go through.. Should be more stable that way if you dont have a proper stand..

My bad, i forgot you have actual resources to make something if you needed to, so a cheap makeshift holder isnt needed lol. Owell
Small leak.last a while.
Did u wedded with map torch that's bad for the refrigeration system..
Heat is heat, explain your statement.
El Mosfet is not entirely wrong: being wedded/married to a MAPP Pro torch would likely be bad for just about every scenario.
