Using a fuse puller or needle-nose pliers, carefully remove the blown fuse from its socket.
Inspect the fuse to confirm it is blown (a break in the metal strip or dark discoloration).

4. Install the New Fuse

Select a replacement fuse with the same amperage rating as the blown fuse (found on the fuse itself).
Insert the new fuse into the same slot, ensuring it is seated properly.
