Replacing.Fuse
The purpose of the fuse is to protect the motor and
circuit board.
If the fuse blows, the light will turn ON but the motor
will not start. You can verify if the fuse has blown or not
by holding it up to the light and inspecting the element
inside the glass (the element looks like a thin wire). If the
fuse is blown the element will be broken in half.
