I am working on LG frnch door refrigerator’s compressor replacement job. Everything was done fine. Recharged desired amount of freon and checked high side pressure 90 and low side was 10 but after 14/16 hours customer calls me back still not cooling.Made sure before recharging freon with nitrogen if the system is not leaking and vacuumed for 30 minutes than charged freon. What is your opinion for not cooling on this stage.
