Frigidaire heat pump issues

[ThatOneGuy713]

I'm working on a frigidaire heat pump. I had a restriction and changed the txv and drier and flushed and added new gas. It ran for a couple of weeks and now I'm pumping down and have 1 degree sub cool and sky high super heat. When I go to heat liquid pegs to 600 and suction is good. I'm missing something I just don't know what. I have good air flow. Indoor coil is micro channel if that matters.

Pull and weigh the charge.

What is the outdoor metering device ?

[ThatOneGuy713]

Txv

Which txv did you replace ?

[VTP99]

Which type of filter drier did you use ?

[ThatOneGuy713]

Only has txv in air handler and I replaced it with oem. Used a biflow filter, and the condenser has a piston

[VTP99]

Have you tried warming the TXV power element bulb ?

Is there a bypass around the txv with a check? Did you pull the orifice when it was open?

[BALloyd]

What is the temperature or even better, the pressure drop across the filter drier?
