Changing out a bad compressor today on a Goodman 410 split system. Low side running at around 150psi / 50 sat temp with about 8 superheated. High side 425psi/130 sat temp with 10 subcooling. Brand new system, pullin my hair out. Was messing with the txv , thinking the evap is flooded trying to get the sat temp/pressure lower. Finally tried to pump down system to check comp. pressure started to go down then " valves" gave out and pressure went back up. Bad compressor right? Not pulling the low side down enough?
I have another client, same system having same problem. Anybody running into some bad goodmans?
