What causes a fuse to melt?
The fuse can also blow or fuse, in this case melt because of a bad contact in the fuse holder. The resistance caused by the bad contact acts as an element. The fuse wire will melt off the end of the fuse metal contact because of heat. It will be best just to replace the fuse holder and the fuse.
What happens if a fuse contact is bad?
The resistance caused by the bad contact acts as an element. The fuse wire will melt off the end of the fuse metal contact because of heat. It will be best just to replace the fuse holder and the fuse. Also check that the wires are securely fastened which can cause the same problem.
