    I'll try again tomorrow. The app crashed and after deleting I couldn't download again because I DIDNT HAVE WIFI OR CELLURA DATA!

    One thing I've noticed on my set on two systems is it got a diagnosis wrong. Not a big deal to me, but a less experienced tech might get sidetracked.

    Both units had a bad TXV. I had high superheat and high subcooling. Pressures were a little on the low side. Low temp split across evap. The diagnostics said unit is overcharged and to remove refrigerant until subcooling is at target. Maybe if I did that step and got my SC to in range it would have then told me there is a problem with the TXV.

    As a newer tech, i see where you are coming from. Biggest issue would be relying too much on the diagnosis. an overcharge would mean the unit would have higher pressure and a low SH. Probably why most people on here will recommend starting with analogs. If you dont understand the numbers, how can you diagnose it?
