The pressure switch is a critical safety component that monitors the negative pressure created by the inducer motor before allowing the ignition sequence to proceed. When it fails, the control board detects an open pressure switch circuit and locks out the furnace — resulting in a no-heat call with the inducer running but no ignition attempted. A failed switch may also cause repeated short-cycling or a fault code pointing to inducer or pressure switch failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Closing setpoint: -0.22\" W.C.
