The pressure switch is a critical safety device that monitors negative air pressure produced by the inducer draft motor. It confirms proper venting airflow before allowing the control board to proceed with ignition. When this switch fails, your furnace will lock out before ignition — often displaying a fault code — leaving you without heat. Common symptoms include a system that starts the inducer motor but never advances to the heating cycle, or a furnace that flashes a pressure switch fault code on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC061 | Factory-matched W.C.
