While the GFCI circuit is a great enhancement to safety, they can sometimes make you think you have an electrical problem when really you don't. If you have suddenly lost power to the plugs in your kitchen or bathroom, your problem may be as simple as resetting the GFCI circuit in one of the outlets. Look for an outlet that looks something like the one shown here. Note the two buttons in the middle. One of the buttons is a test button and the other is a reset button.
