refrigerator 134a

Dano960, I just replaced an evaporator on a GE refrigerator last Friday. I scaled in 5.5 ounces of 134A and my suction pressure was +1 and my head pressure was 110 lbs. My indoor ambient temperature was +72 degrees. If you have a refrigerant scale its best to evacuate and scale it in for the exact charge. This unit was running for about one hour at these pressures.
