    Furnace Electrical Controller Board - Dead
    I have a Bryant 383KAV036070 model furnace, but the circuit board is dead. My house was hit by lightning while I was out, and various items were fried - e.g.. A couple phones, a stereo receiver. Many things were OK. I have a two of these furnaces and the second one is fine. I get 24.5 VAC from 115VAC to 24.5VAC transformer to the controller circuit board as indicated in the wiring schematic. Also, the fuse on the board is OK. The LED light on the board does not light up, and no signal is sent to the outside condenser solenoid when I move the thermostat to very cold. In addition, nothing happens when the thermostat is moved to high heat. The other unit does all of this just fine. I am thinking I need to find another board or get this one fixed. There is a processor chip on the board. Best thing I think would be a used board. Any ideas on how to get a used board or where to get my board checked out and fixed?
    Thanks.

    Almost everyone in the trade just gets replacement boards. Too much liability is at stake to repair them. You might look on Ebay for the board.
