Hello people, I brought the refrigerator to check it well. Place a pressure gauge and I saw that it was low on gas (20 psi), when it was started with an amperometric clamp placed it went empty and threw me 1 amp of consumption that in my opinion was little, but hey it was with little refrigerant. The condenser and the ball were at room temperature, another indication of lack of gas. Stop everything and let the sisstema balance and with 20 psi look for losses in welds and in the rush of the freezer evaporator, get no results. I saw that the refrigerant charge of the refrigerator was 100 gr so before separating the refrigeration circuit in two and pressurizing with nitrogen I saw that the gas charge was 100 gr, so I decided to charge and see if it worked (to rule out any capillary filling). When putting a little of refrigerant began to heat the condenser and the motor compressor, in the freezer began to frost the evaporator. Everything indicated that the system is fine but with a gas leak where a fence to know. Already with everything stopped and about 55 psi I started looking for losses again, I made sure to enter the evaporator since once I had a puncture problem in that sector. Almost demoralized, it occurred to me to flood the collecting tray of meltwater that has a kind of coil that is made with a spiral of iron pipe at the outlet of the compressor discharge before entering the condenser and when I started to move it since I had waste I see it starts to bubble .... Hallelujah I found the loss !!!!! Now that I leave it well explained for someone to take advantage of it, I wanted to ask another colleague with more experience if that spiral can be done in copper, since if the one who has it is with a puncture, I can fix it, but maybe this is all deteriorated and can be punctured again. A 1/4 spiral copper spout withstands the compressor output pressure well? I would appreciate someone to answer me
