    are you sure the rev valve slid?

    did you take temps across rev valve?

    were ID & OD fans running?

    are you saying suction was 168 in cooling, with a 200 head?


    got to be clearer than mud for assistance
    It`s better to be silent and thought the fool; than speak and remove all doubt.

    What Tstat does it have, and does it have an outdoor sensor with hp locked out?

    ODT should not have it locked out, be sure settings on stat arent back to default due to power outage and pressure seems ok for lp but way to low on hp. Get system working right then recheck.

    The suction pressure is way high. The SST for 168 psi is around 60F. For that to be normal, the ID would have to be 100F .

    The head pressure is 25 or so, low for 60F OD.

    There are obviously some other things going on with the system, and with warrior00's deficiency in diagnostic skills, I'm half-way wondering if the compressor was even running when he read the pressures.
