The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor. It confirms that proper venting airflow exists before allowing the control board to advance the ignition sequence. When this switch fails — or when the hose, port, or inducer itself causes it to read incorrectly — the furnace will lock out prior to ignition, often displaying a pressure switch fault code and leaving your home without heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC061 | Factory-calibrated W.C.
