WARNING: Before you do anything else, make sure that the circuit breaker or fuse box is turned off. This will prevent you from getting shocked.
1. Locate the blown fuse.
Find the fuse box in your home, which is usually located in the basement, garage, or utility closet. Open the fuse box and look for the blown fuse. A blown fuse will have a black or brown mark on it, or the filament inside will be broken.
2. Remove the blown fuse.
Use a pair of pliers or a fuse puller to remove the blown fuse from the fuse box. Be careful not to touch the metal ends of the fuse, as this could cause you to get shocked.
3. Replace the blown fuse.
Insert a new fuse of the same size and amperage as the blown fuse into the fuse box. Make sure that the new fuse is pushed all the way in until it clicks.
4. Turn on the circuit breaker or fuse box.
Turn on the circuit breaker or fuse box, which will restore power to the circuit that the blown fuse was protecting.
5. Test the circuit.
Turn on a light or appliance that is connected to the circuit that the blown fuse was protecting. If the light or appliance turns on, then the fuse has been replaced correctly.
