Check the type of fuse
Use the correct type of fuse to protect the appliance against current overload.
If a fuse has blown, find the cause with due care and replace the fuse with one
of the correct rating.
If you do not use the right fuse, not only will the appliance not work properly
but the failure could become worse. You must ensure you use the correct
fuse.
