Motor is pulling to much amperage to blow the fuse. Gas burner pulls no volts.

It could be something as simple as dirt or paper or any other # of things sucked up into the blower impeller, causing it to work too hard. It could also be that the motor is flat worn out (but I doubt it). It could also be a hot wire (black) shorting out somewhere.
