I find the thermostat wiring is often to blame, when it is run next to or through the duct it shorts to ground (r-c) and kills the fuse. also have seen mice eat the thermostat line at the condensing unit and cause the Y-C short thus blowing the fuse. First step, disconnect the Y and C going to the condensing unit, then if it continues, follow the thermostat and humidifier wires to see if the chaffe on the duct. I catch these all the time!
In "short" (pun!) it isnt usually inside the furnace, alternate way is to disconnect the red wire for the thermostat (at the furnace terminal board) and run the furnace on no stat or replace the wire temporarily.
