Great video I know you guys don’t like showing the same kind of calls over and over but I enjoy them. Thanks for passing on tips and tricks to make working out here in the field easier
Thanks James I appreciate that, it's important to hear from my viewers because until you get really big the comments are the only type of valuable compensation you get. There's a lot of controversy over making these videos that I deal with. Sometimes it just doesn't seem worth it.👍👍
Your money on that, there are different ways to diagnose issues but seems to me you did the proper method. I always find it difficult to where to locate the bulb on those small coolers like yours the solder joints are in the way right before the trap. I've been in the field for over 35 years and now retired, starting to make my own videos to help others. Unfortunately I'm disabled and can no longer do field work. Good luck to you and I'll subscribe
HVACR Survival thanks I sure will send you a link, only got a few posted right now there pretty bad for posting content. Trying to make them shorter to retain the viewing audience lol
Nice job Rick, excellent trouble-shooting methodology! I learned something there on the solenoid!! Nice trick! I would have thought LP for sure from the initial look, goes to prove why one shouldn't make assumptions before the full thing is checked. Just a fantastic video. Learned a lot! THANKS!!!!
@@hozerhvac4406 I still do residential but I don't have to sell anything. I keep hearing that a lot lately and makes me wonder if everybody's turned into a sales person.
Man , kinda tricky to know if it's the solenoid or the Txv since they're so close to each other . I would have probably gone with the solenoid and ended up chasing my tail . Good catch indeed !
Pound Ounze PSI etc is not a problem to convert to Industrial from Imperial (english/american). But what is a ton from english ? We have also tons in Europe and 1 ton means 1000 Kg or 2205 Pounds of weight. If you talk about a 15 ton system it has 33075 Pounds of weight for me at 3-6 Square Meter and i can not see the mechanical Structure to carry this things on a weak roof. So what is meant of tons in america for klimate systems ?
@@HVACRSurvival so I have 1 ton of cooling and heating private and my friend 3 tons of cooling and heating. We care only about efficiency. In america there are very less Inverter systems. They are the most efficient way to regulate. I am not a HVACR but an industrial engineer and have learned a lot from you.
Sporlan valves I start at 2.5 turns out. Medium temp on parallel racks get 6*-8*F coil SH; 1 on 1's I try for same SH but minimum compressor SH overrides that.
2.5 turns sounds interesting, I usually rush the adjustment and then spend forever getting it where I want it I didn't have as much time as I wanted to tune it in as I wanted because the customer was worried about cost. And as you mentioned, I was already to low on my company superheat.
Thank you for this great information about txv and s valve, I have a question about a walk in cooler that has three evaporators coils and in exh one there is a txv , r 22 , low pressure is about 25 , high side 220 psi , the suction line is frosted all the time ,i replaced the filter drier and pulled 200psi nitrogen and deep vacum but after all that the problem continue, and I dont know which one of the txv is bad or the or restrected , do you recommend mento replace the 3 valve or just the power head of the three valve thanks you for you support
@@rahmanyalshugaa3556 check the superheat of each txv and see if they are truly flooding back to the compressor. Then do a superheat at the compressor last, you should have 8-10* at each of the txvs and at least 20* at the compressor. Then go from there.
6-8 for freezer, 8-10 for coolers from what I've read from HeatCraft. If you get the S.H. to low and you might have problems as the outdoor temps change. ***Also don't forget the compressor manufacturer generally wants 20* at the compressor min. and that overrides the TXV. But this isn't a perfect world. This customer didn't want to spend a lot of money on this after all the covid-19 crap.
yes, because too much heat loss/gain from air flowing over and condensation, which could make it react too slow and/or read wrong from condensation evaporation or lack there of. there's a reason why they insulated them to the pipe years ago ;) also in other coolers sometimes it's possible to get product shoved against them and that will whack them out for sure!
I think it will be more accurate with it than without it so I try to follow industry standards to cover my butt against callbacks. Will it work without it? probably but there is always a possibility it might cause a weird random issue.
To add to your disclaimer...alot of techs are putting a disclaimers screen at the beginning of their vidjas that way your covered with all.. I love how vice grip garage has his...im an idiot, dont do what i do...this is for entertainment only
Thank you I'll have to check it out👍. I have a friend that's in law so I asked him for some advice. I have it written in my description of every video.

Same. Even calls that are common are fun to watch. 😎
That's cool to hear! thank you Ben 👍😁
I agree with you james, there's always something to learn, especially for us new guys!
Thank you 👍🏻👍🏻

@@HVACRSurvival Here's a link to a short video I made last night. Just let me know what you think thanks. th-cam.com/video/RASFmFWmrmM/w-d-xo.html

It took a bit to find it, I hate preset limits like that. My editting made it look smoother than it was 😏. I appreciate the view and comment.
That birds nest of wires was crazy. What a mess.
That's the Ohio roller nest 🤣🤣. Might have been wired by buckeye Bob 😎
Great Video. From a residential guy I took a lot from that.
Thanks Hozer👍. hopefully it will help if you get on one.
HVACR Survival hopefully one day I branch out to the commercial side. The damn sales environment of resi eats at me
@@hozerhvac4406 I still do residential but I don't have to sell anything. I keep hearing that a lot lately and makes me wonder if everybody's turned into a sales person.
Good stuff Rick
Thanks man 👍👍
I like show glasses. They are showing what is going on. Not every sensor can talk about the real physicals.
Man , kinda tricky to know if it's the solenoid or the Txv since they're so close to each other . I would have probably gone with the solenoid and ended up chasing my tail .
Good catch indeed !
Great video! Nice tip with the amp clamp on the solenoid. Thanks for adding my channel on the end link!
No problem, I got help from Chris so I'm willing to help the next guy that does good work. Keep at it 👍🏻👍🏻
Nice Job Rick, I didn't know Bristol made medium temp compressors. Great video as always!
Thanks Shiva👍🏻👍🏻 Glad you liked it.
Solenoid line is less likely to be restricted compare to txv. Thanks for sharing.
That's what I was thinking but I never had a txv clamp down like that. Famous last words.... It was working fine before it stopped 🤣
Good work sir. Thank you for the entertainment.
No problem, thanks 4 watching Kyle 👍🏻👍🏻
Nice diagnosis by the way....
Thanks Jesse 👍👍, it took a bit, I haven't had a cooler txv do that to me before, not 💯% cut off like that. That was Kinda weird one 😲
Good one Rick
Thanks Greg 👍👍
Great troubleshooting vid Slick Rick ... Done a shot of good ole Tvarscki Vodka in your honor ... Lol ...
You do man Fast Eddy👍👍😁🤣
Good video brother!
Another awesome video !

There's 12,000 btu in a ton of cooling.

thanks for the video, did you use the other method for the superheat, if so ,what differential are u looking at for the cooler?
It was within 2 degrees. I forget witch way. Thanks 4 remembering that 👍🏻👍🏻

Clarify for me what you have. You have 3 coils and 3 txvs?
Yes 3 coils and 3 txv

Thanks a lot for that seriously issue
Your welcome
What did the sight glass look like?
I don't remember, it's been a year ago. I would think it was full or I would have added refrigerant vs replacing a txv.
That is what i was looking for!@@HVACRSurvival
10 F superheat I usually hear its 3.5 to 4f superheat at the evaporator for walk in cooler and freezer ?

@@HVACRSurvival sounds good man 🦸♂️ you are super man
Lol. No I'm just just a tech playing a Dr on TH-cam. 🤣
Do you really think insulating the bulb makes a difference? I feel like it doesn’t
yes, because too much heat loss/gain from air flowing over and condensation, which could make it react too slow and/or read wrong from condensation evaporation or lack there of.
there's a reason why they insulated them to the pipe years ago ;) also in other coolers sometimes it's possible to get product shoved against them and that will whack them out for sure!

It was done by another company before us.
