Question

Our outside oulet which our minimal christmas lights are plugged into, stopped working. I tried to reset all of the breakers, and there is no BFI button that appears to control it. The house is about a year and a half old. Any ideas before I call in a pro? Husband is going to be home for just 13 days for Christrmas before returning to Bagdad, and I really want the lights on to greet him when he gets home. Giner
