1. Check your circuit breakers are on.
2. Check to see if you have 120V. at the controls to the AC on the roof.
3. There are two capacitors on the unit, one for starting and one for running. You may have a bad starting capacitor. Pull the top cover off of the AC and then open the control box on the side of the unit. Capacitors are metal oval long gated devices with wires connected to them. If there is a bulge on one of them, that maybe your culprit. Make sure ALL power is disconnected and you bleed off the existing capacitance on the capacitor by grounding the wires on the capacitor to ground. Wear gloves!
4. If it is not the thermostat, control wires (low voltage), capacitors or circuit breakers, it could be the unit is shot.
Good luck ;)
