    It either has moisture in the system, you have a leak, or the cap tube is blocked. It May be that it is undercharged. Slowly add on the low side till the high side get’s the equivalent of 20 to 30 degrees above the high side ambient.

    If it starts cooling, Vacuum it out and discard the refrigerant and recharge. Make sure to use a micron gauge to less than 400.
