The fuse pop’ d after the short. The traces on the back show that the big electrolytic cap was punching out a big shot. I imagine that there is a surge at power up of the motor to charge the capacitor.

Just out of curiosity, how much are the variable frequency boards?

The board for the blower can only be bought if you buy the whole blower, it’s around $1000
