HVACR Videos has a decent explanation on Headmasters, and how to charge the system for them WRT winter charge. Would recommend. "WALK IN COOLER ONLY WORKS WHEN IT'S WARM OUTSIDE - HVACR VIDEOS"
Nice that you tried the non invasive approach to determine the problem. Hopefully you find a leak somewhere in the evaporator since it was way to windy to find a small leak outside.
Hey Brad- im still waiting on approval of my quote to go back and do a good thorough leak check, when and if they do Ill film the follow up-- thanks for watching
Perfect explanation, R404 systems can be a bit sneaky,critical charge.. A little off and cooler temp. ,will rise.. The amperage .was a big clue,to undercharged., Reminds me of a couple of the R502 system days.. A few ounces makes a big difference in load.. Another great video, Bryan Tyler Refrigeration
@@curioushvacguy6876 Fan cycle switches., To be honest with you , I only ran into 1 headmaster system personally in the early 90's. Im guessing our weather here is more typical of the fan cycle switch. Whereas in colder.weather headmaster is used more. In south texas we do not get much.freezing temps.although this coming week we're supposed to get to 31* midweek.. That was a awesome explanation on that video.
Hey i have a fully charged 404 walk in beer keg cooler that runs a hot liquid temp. Its all brand new and i can figure out why. Its not running as efficiently as it was with cooler temperatures outside. Takes forever to cool down.
I think that was part of the issue there, someone may have charged it up in the summertime and didnt add the winter charge- my idea was to return and do a full thorough leak check and then add the winter charge and check the receiver level. Thanks for watching
In Australia it's illegal to "top up gas charge" to find the leak , you have to fully recover the gas and nitro test. Are you allowed to do that in the us?
Hey Calvin here in the US for comfort cooling if the leak rate is more then 10% of the entire charge then a repair needs to be made or arrangements to repair the leak need to be scheduled and communicated with the EPA. With that being said as far as topping off the charge on a known leaking system, as long as its within that percentage Its ok- also I had a plan in place to return and charge with nitrogen to find and repair the leak at that time. If there was refrigerant blowing out the side and it was loosing alot more the the 10% rate per year that may be a different story. Thanks for watching
If you recover the gas and charge with nitrogen then how can the leak detector pick it up? (Not in the trade here just been trying to pick up hvacr knowledge the past few months).
Do you know any Walk in cooler repair men in Houston that know how to repair this problem? We have gone through 3 different companies and no one seems to know what the problem is eve. After we explain exactly what is happening. This exact same issue is happening to ours.
Nice attempt at non invasive testing - I think it really only works if the system is operating properly, but if we are called out it’s likely that there’s an issue so we end up gauging up anyway.
Exactly right 404- if you didnt commission it from the beginning and if you werent the only one to touch that system then you dont have a good enough base line to really use the non invasive approach. Thanks for watching 404
I like the way you think Rookie, lol-- I didnt discuss this in the video but my plan was to do that when I came back for a more thorough leak check since the manager said they have to have the system charged once a year.
What's that smell! Crap, burned breakfast...got distracted watching another Curious Vid! Good training vid for new guys to not just drag the jug, dump and see what happens.
Thanks bro, I'm a bartender and I just had to fix our cooler. Couldn't have done it without ya.
Thank you for touching on this! I just read about it in the book and couldn't quite picture how it worked.
Awesome- what book are you reading?
Thanks for watching
Curious HVAC Guy commercial refrig for hvac techs. Jefftg503 on ig
I've seen numerous guys explain headmasters, I think you did the best. Thank you.
Good stuff brotha. Your best bet is to check the correct winter charge. Sporlan has a few tricks and equations you can use to figure it out.
Thanks Ritchie

Thanks, Ill check that out

You're a great tech man, God bless you you explain so well
Thankyou , I learned so much from you as first year apprentice.
I understand headmaster much better .Good job 👍
Glad I could help
I like you explanation of the headmaster.
Thanks, glad it helped bud

Ty broski- in my 2nd year and new to refrigeration this helped a lot
Good stuff.... I got to watch it again to get the headmaster function 💯....
Thanks
Perfect explanation,
R404 systems can be a bit sneaky,critical charge..
A little off and cooler temp. ,will rise..
The amperage .was a big clue,to undercharged.,
Reminds me of a couple of the R502 system days..

Nice vid!! This week I’m Assuming temps have dropped outside up north. 😂🤣
For sure- they came back up this week though
Awesome video and great explanation on the hpr 👍
Thanks
It's time: 😎 Hitting the bell for Bill. 👍
Awesome- thanks Juan
Great teacher good explanation of head master!
Hey we use the same leak detector! Right on!
Hi 5 bro, lol-- im happy with this one
If the temp is getting colder it may just be you need to add the winter charge.
Thanks for ur explanation on the Head master
Awesome educational video Thanks bearded wonder
Thanks
Good teaching vid Bill ... Appreciated ...
Thanks Eddy

Great explanation Bill
If your in low ambient, maybe winter charge wasn't added?? Don't have that issue here I've ended up yanking email out in the tropics here

@@curioushvacguy6876 awesome thanks for the clarification, also what's this winter charge mean?
Also love your vids man!

@@bluered1322 you use bubble spray
Another good one man!

That headmaster isn't functioning due to the sensing bulb being cut. Could be wrong. Only dabbled in refrigeration
Tnx for the explanation on headmaster...
No problem, thanks for watching
I did one yesterday. I changed out the thermostat. Easy day lol
Thanks for the explanation. Awesome video

Torch it. Probably just winter charge. Good video bro.
