I had the same problem with this unit. I needed to have mine replaced also. You could check the safety switch. If you look on the outside of the blower housing there is a small circular switch that is screwed onto the sheet metal.
There are wires that connect to both sides of that switch. If either is disconnected, the blower won't operate.
If the safety switch wasn't made then the transformer wouldn't have power to bring on the outdoor unit. If the idiot light on the board isn't on I would check the connections to the board, the line power to the transformer is connected ahead of the other circuitry on the board.
