I was given a fridge from my customer, it has a leak in the ff coil. So I fixed the leak and changed the dryer. I normally just charge the low side to around 2 psi. I could hear everything gurgling, I came back in an hour and it didn't drop at all and condenser was room temp. I went up to 15 psi on the low side and the discharge warmed up and the freezer got around 0'C. Is there a special procedure for these vcc dual cool fridges?
