r12 refrigerator pressures
Hey guys , new here, usually in residential tech area.... I have an older refrigerator that is not cooling. Why are there 3 tubes coming off the compressor, 2 to the condensor and the third to the evaporator. I put a line tap to check the pressures but don't know what the low side should be. What should the equalized pressure be at ambient 70 F?
