As some have stated, on badly designed equipment with under-rated fuses the fuse can be stressed on power up and resistance may rise leading to eventual failure. This used to happen in the past with Zinc based fuses. This should not happen with modern copper or silver based fuses in proper modern well designsed equipment. Should you experience an improvement it suggests that the original fuse was faulty. That you hear no directionality is correct - there isn’t any.
