Hi guys, I have a doubt this is my first refrigerator that I repair, I had a puncture in the evaporator and I welded it with aluminum, because they had already done a previous job but it was badly done I had the puncture with poxipol, and lost all the gas now I charged gas and it is cooling but my doubt is this: first I welded it, changed it filter and then I did a pressure test which did not give me losses because the pressure remained at 130 psi for an hour then I made a vacuum of 50 minutes and I charged gas until I reached 7 psi or so and cooled barbarian then turned it off and turned it on again after two days and cooled well but the pressure is now at 0 psi and does not lift the one I leave ( 7 psi) My question is whether it is because today the ambient temperature is lower about 10 degrees less than two days ago, the gas is r134a and the amperage was 1 amper and now it is 0.8 I do not know if I should recharge more gas until 2 or 5 psi, I'd appreciate it later eg doubt atte ariel.
