Since the fan and all the circuitry in the furnace works on 12V, I would remove the 12V fuse to the furnace for a few min, then replace it, that might reset something on the control board and it might then work properly.
The flashing red light has some meaning, what that is I don't know, but it might be as simple as a reset.
What furnace do you have in your unit.
