    Goodman furnace problems
    I have a Goodman model CAPF1824B6BA that will not ignite. The LED flashes 3 times which the code states a pressure switch stuck open. Is this something I can correct or do I need a new part. The exhaust fan and blower fan work but no ignition.

    Your giving us the model # of the evaporator coil(cooling side) we need the furnace #. You have a round disk that sets above the burners and below the inducer vent motor-- two wires and a rubber tube go to it. You can remove the tube opposite side of pressure switch - blow and suck lightly on it - you should hear the switch click. Put tube back on and give it a try.
