The pressure switch monitors negative air pressure produced by the draft inducer motor and signals the control board that safe venting is confirmed before the ignition sequence begins. When this switch fails or sticks, the furnace will lock out before ignition — typically with no heat, a blinking fault code, or an inducer that runs continuously without advancing to the heating cycle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
