Outside AC unit wont start

The low voltage is good at the t-stat. The inside blower comes on and the outside fan comes on but not the compressor. I don't have 24 volts at the coil side on the contactor. I have 24 volts on the circuit board. This is a ICP unit. Model #CH7560VKA2.

What terminals on the control board do you have 24VAC power? When your thermostat is calling for A/C is it energizing the cooling terminal (usually Y, Y1, etc.)?
