ac not turning on outside unit

[rgall]

have a Ducane unit outside.(4ac13L30p) The first time this year I went to use the AC, the fan inside kicks on and blows the air around but the house wasnt cooling. I went outside and the unit isnt doing anything. Fan hasnt moved, no humming, ect. Its only a few years old. I reset the breaker. I opened up the outside unit and pushed the button and it didnt power on. There is power going into the button, and also when I press the button there is power on the other end at the connections on the button. Wires all look good, no fraying or broke wires... Any thoughts or suggestions? Start up Capacitor?

which Button ?

pictures ?

Or do you have a wiring diagram you could upload ?

The one I have doesn't show any "button"

If you are referring to the "button" in the center of the contactor and your are getting 220/240 volts out of the contactor I would check or replace the capacitor.

Does the contactor hum when the thermostat is set for cool?

Is 24 volts going to the low voltage side of the contactor?

make sure to check both inside and outside breakers
