    Thank. 550 testo. I had the analogs out to recover but did not get a pick. Hopefully it is just the drier and I won't have to crawl in.

    If I recall from the news story, it's a Piper Arrow atop a Cessna 152.

    compressor discharge temp 71.8
    suction temp 33.1
    I'm guessing compressor discharge was 92.7 and LL temp was 71.8?

    Your numbers are telling me floodback and low indoor airflow. 0° SH instead of 8.5°. There can be considerable measurement error on a package unit if you don't insulate your sensors to the line.

    Are you sure it was completely thawed out?

    Yeah I'm not seeing a restriction with 8.5 degree superheat.

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    It had thawed because I disconnected second stage and let first cool the space. I was also think low airflow but first stage was working fine. I want to check above the ceiling on Monday and look at the ductwork. I know it has a hard return with flex to four 16" round 2 x 2 grills. Maybe the return is insulated on the inside? I want to see.

    That subcooling is pretty darn high that's for sure. I like the testo display. If i didn't read so much more negative than positive about them i would of went with them

    First stage would have more air forced through it if the second stage portion of the coil was iced over. Now that the coil has thawed the first stage SST is probably running low too.

    Subcooling is high because it's a fixed orifice. With a 25 degrees delta T I would say airflow too.

    Usually when those manifolds go south its just one or two metering devices and its almost impossible to clear the restriction.
