Yes I skimmed through so missed that. As it seems to be a converted ice box? my money would be on poor to no insulation, ask me how I know this.

Well like all things here you're playing a guessing game with very limited, and sometimes distorted, information...
Even so, it gives the op pointers to maybe help ....

Maybe so,
(where were you in Venezuela? )
It's not what I said, what I said was the pressure are different in an aircon than a fridge..believe Google or not, the low pressure (suction) on a split aircon unit can be 70psi, and in a car 30 psi, the low pressure in a fridge will be usually less than 5 psi...
This information is all over YouTube and Google, I'm not trying to suggest you are wrong I was and still am simply saying the pressures are different in aircon and fridges...

it all depends on the gas and temperatures.
Stop digging

In the olden days when I was gassing units in fridges and air cons it was freon 12 and 22. Pressures were different at similar temperatures. Then 134a came along, used in cars aircon and fridges. Pressures identical in similar temperatures basically. Then after about 2015 they were changed again with various gases used, so it was back to the olden days of different pressures at similar temperatures. For our fridges, most will have 134a in.
So as I keep saying, a catch all answer isn’t possible, as I have said all along, it depends on the gas and temperature as to what the pressure should be.
A fridge with f12 in, pulling hard as the temperature dropped towards 0 would be showing towards 0 and 150 ish psi, it all depends!

Not necessarily, but i do know from my own experience.
As for believing anything on the internet, that of course must also include you, me
And Bav381
Do you use Google? If so why?

It's quite simple really, someone supply an information specification on the different systems,
Can you do that ? Without the aid of Google?

Ther was a forumite called superheat6k
Maybe he can comment.

Don’t need him, it was part of my working game in Africa and the Middle East
