    Concord furnace pressure switch
    The diagnostic LED light indicates that "pressure switch is open while inducer is on . Does that mean that I have a bad pressure switch or is it something else

    Check all the hoses and orifices on the pressure switch first. Sometimes they get clogged with dirt.
