The Ac Unit On The Outside Will Not Come On At All. I Know It Is Getting Power Because The Switch On The Outside Unit Closes But Nothing Comes When I Turn It On At The Thermostate Please Help If You Can,hanknub1

Check the inside breaker for both the inside and outside unit.

Check the disconnect outside for a tripped beaker or blown fuses.

The switch on the outside(contacter I suppose) is controlled by low voltage (24V) which is sent from the tstat,which gets its power from the transformer in your furnace.you still need 230V of power to run the condenser(outside a/c unit),which is fed power from you main breaker box with a disconnect in between which both should be checked to insure that they are turned on.
