    I will have to remove the old one to find out.
    I was hoping someone had the specs for the unit.

    It will have to be removed for repair anyway.
    Will the blade move freely, if not the bearings are toasted.
    If it moves freely there is a slim chance the run capacitor might be the only problem.....slim.

    You could remove the grill or mounting panel and haul the entire thing to a motor shop......include the capacitor with it.
    Mark the location of any wires you unhook.
    Sometimes removing the blade from the motor shaft is very difficult. Some people change the blade, motor and always a new capacitor. A cracked blade or one with loose rivets can ruin a new motor's bearings in short time.

    Thank you for the advice Jughne
    The unit runs fine for about 15 min then it trips the breaker, the AC guy said right away that it was the fan motor, and that the compressor was good solid 15amps reading.
    Also the blade does moves freely.
    Any chance it's just the capacitor.

    If there was an AC guy there he should have checked the capacitor, fan motor might not even start with bad cap.
    Less chance of cap at fault.
    Did he measure amp draw on fan motor?
    A motor that small can trip a breaker only so many times before the smoke comes out of it.

    Condenser fan motor is important to match the RPM.
    I think it is best advised you read the nameplate and match like for like. This is a good time to see if you can save the condenser fan blade, for reuse.
    You will need just, the RPM, Voltage, phase (likely single phase), frame, and horse power.
    Tell them you will want a new capacitor to match the new motor.
