Hi Miguel, your refrigerator, you may have some obstruction in the filter, but more suspicion of a small refrigerant leak, it is natural that the pressure is low if you do not have the full charge, in addition to how you know you have the full charge without frosting on the bottom panel and without return reaching the compressor. Unless you have removed all the refrigerant and reloaded it by weight on a scale and of course having the data in your hood of the exact amount, I do not see how you know it, without even seeing ice or frost manifesting in the return, which obviously for this to be accomplished first, the conservation panel must have already been frozen. I really don't see how. The pressures of work in the return of a refrigerator, it is true that in theory they oscillate between 7 and 2 pounds of approximate pressure, but this is fine if the rest is fulfilled and that rest is the refrigerant that is missing to complete the cycle, completely filling that bottom panel. Have or not the desired pressure. What I try to understand is that we must first ensure that the cycle is closed, with the full full and then we would take care of finding the ideal pressure, which would surely come by itself once the objective was reached and after the time passed, the refrigerator manages to overcome the thermal load first and with it lower the pressure and the cold temperature. If after this time is not fulfilled, then it should be checked that the compressor is capable of compressing enough or not. That the aforementioned refrigerant leak does not already exist. That there is no clogging in the filter drier or in the capillary. And finally that the door, with its rubber seal and ferrite, tightly seal the low conservation area of the refrigerator. Luck.
