    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.

    FENG yay, hey I know you've gotten a hard time in some of your posts, by the way it's because you tried to do a tutorial as you would for a lamen but for guys who do this every day for a living.

    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.

    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.

    If it's a scroll, I'm sure you already checked to see if it is running backwards, but just throwing it out there.

    with suction and discharge pressures almost equal the reversing valve is not going to shift. I think there is a restriction somewhere and that was what got the first compressor killed.
