I believe that this is a poor design more than anything else. Fuses are not only rated by their amps, but whether they are 'slow burn' or 'fast burn'. This is really a fusable link, and designed for 'slow burn'. It really shouldn't be! If there is excessive current draw on the blower motor, the fuse should pop right away.

My fuse burned without starting a fire, but the plastic housing was melted due to the heated slag of the fuse material. Also, upon close inspection of the material, the fuse link had obviously heated to the point of a metal fire and was severly oxidized and liquified.

I'm going to replace mine with a circuit breaker.
