What fuse should be used to replace the burned one?

To replace a burned fuse, you should use a fuse with the same amperage rating as the original. Check the markings on the fuse or the device's manual to determine the correct amperage. Additionally, ensure that the replacement fuse matches the type (e.g., slow-blow or fast-acting) and voltage rating required for the circuit. Always disconnect power before replacing the fuse for safety.
