GFCI Won’t Reset? Safe Checks Before Replacing the Receptacle
A GFCI that will not reset may have no incoming power, an active ground fault, moisture, a failed device, or a downstream problem. Entry-level maintenance can unplug loads, dry the area, check known upstream protection, and test reset buttons—but should not open energized boxes.
