Turn off the main power and unplug all devices from the affected circuit. Locate the fuse box, identify the blown fuse (one with a broken metal strip or cloudy appearance), and replace it with a fuse of the same rating. Restore power and check if the new fuse holds. If it blows again, a more serious electrical issue may be the cause, and a licensed electrician should be contacted.
