Hi my name is Robert...

I would see if you have power going to the control box that is inside the AC unit, if you pull the cover down inside and look up you should see the control box and it should have a green light that is solid if power is going to it, if it is green check all your connections at the thermostat and at the control box, it could be a loose connection, bad thermostat IF the light is green. IF it is not green then you have a blown fuse, you have to have a fuse panel inside with fuses. On some of these newer units there will be a panel that has lights and if the light next to the fuse is red then the fuse is blown, I think that style panel is an option, look in all your cabinets, next to the breakers and in the closest for the fuse panels. I would get a 12 volt test light and probe each fuse for power, a fuse can look good but if the wire came off at the fuse block you would never know so it is always good to check for power.

Click HERE and this will at least give you an idea of how the system is wired up and what that control box looks like with the green light...

Hope this helps some.... Robert
