Sometimes the rain causes GFCI’s to trip, and we lose lights and power to electrical outlets. Calling the electrician however, may not be necessary. So the GFCI is an outlet that looks like the one below. It has a TEST BUTTON and a RESET BUTTON. You should try to push in the reset button to bring the power back. If this does not work, then you may want to call an electrician. Very often, is such a service call fixed by simply pressing the button. Save some money before you call an electrician out. Thank you!
