What do you do with a fuse once it blows?

If a fuse has blown, you will need to replace it. Start by turning off the master switch to the box (you’ll need a flashlight afterward), and take out the affected component – it’s usually held in with a couple screws or brackets. You can use it to find an exact match at your hardware store.

What does it mean when a fuse box switch won’t reset?
