Yes, fuses do fail. They're creating some resistance to the current and expanding and contracting with the resultant heat. You shouldn't be worried unless the replacement also blows.
Can fuses go bad?
Yesterday I turned on my Halo JC-1s for a little listening. As I walked over to drop a CD in the drawer I smelled a slight burning odor. When I looked back the lights were out on one amp. A check of the line fuse verified it had blown.
Since the Owner's Guide did not specify anything about fuses I sent a message to Parasound to make certain I used the proper replacement (blown fuse was not marked fast or slow blow). In spite of it being late Friday afternoon before a holiday weekend I received an almost immediate reply. Regarding my question on why a fuse would blow a second or two after turn on they suggested it could have become weak. This was a 12 amp fuse, does that seem reasonable?
