    Goodman Furnace - 3 blinking lights.
    The service panel says "Pressure Switch Failure to Close" I removed the tube form the power vent motor. If I blow, I still get 3 blinking lights. If I suck during power up, I get 2 blinking lights (blocked open),

    This means the power vent motor is bad, correct?

    More info... I measured the voltage across the wires for the power vent fan, and read 0V. Not getting power to the Power vent. Bad circuit board?
