    Assuming you have a clean filter,2nd is the new motor running fast enough,, same RPM`s ,3rd has the evaporator and condenser coils been cleaned,, 4th is the fan blowing out the top and not sucking down into the condenser,5th,was the fan blade put on the motor correctly and in somewhat the same depth as the old one was?

    This is just a start to give you some things to look into
