0 well it shouldnt short out ther should be a 3 amp fuse on it for the low voltage side. if the board shorts out and ther a burnt mark on the bottom of it its either coming from two places . one the transformer or the fan capacitor is shorting it out. try to disconect the wires from the motor to the board then power it up. if it remains on you have a problem with the blower motor or the capcitor.
