Maybe if we all just listen Feng will teach us something new. Give him a chance and let him speak.
I am so excited!!!!
I hate those low loss fittings sometimes.
Sounds like above mentioned. You are probably not fully piercing the service port. Inside your hose is the fitting that presses in the core. Use your needle nose pliers and pull it out a little bit (out of your hose). Or loosen the core (tighten when done) or replace the core.
I hope you keep posting, you will get a ribbing but it's fun and you lighten up the forum a bit.
Good luck fengshvac, keep working and learning everyday.
sorry I had to leave for a minute. I bet you are right - not piercing. I'll check first thing. thanks to all.
is this a scroll or recip?
if it's a scroll i believe it needs more then 50% of charge to work. use your recovery machine to pump the refrigerant into the unit.
if still reading funky it's either your gauges or r/v.
how much 22 did you remove when you changed bad compressor?
If it's a scroll, I'm sure you already checked to see if it is running backwards, but just throwing it out there.
