How do you know if a fuse is blown?
In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced. If you cannot see whether the fuse is blown, follow steps 4 and 5.
Will a blown fuse fix itself?
A blown fuse may be discolored, cloudy, or have a melted or broken metal piece inside. With the main power still off, unscrew the blown fuse and remove it. Never replace a blown fuse with one of a higher amperage, which can be dangerous or can cause damage to your electrical panel wiring.
How do you change a fuse?
Replace the old fuse with a ceramic fuse of the same amperage. If there is a fuse holder on the bottom of the plug, gently open it using the tip of a slot-head screwdriver. If not, unscrew the large central screw on the base of the plug and open it up. Remove the fuse using a screwdriver, as before.18 Jan 2010
