The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor. It confirms that proper airflow and venting are established before allowing the control board to proceed with ignition. When this switch fails or sticks open, the furnace will lock out before the ignition sequence begins — leaving you with no heat and often a flashing fault code indicating a pressure switch error.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-matched water column (W.C.) rating | Single-port or dual-port configuration as factory-specified | 24V control circuit compatible | Direct drop-in replacement for part number HK06WC061\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier pressure switch calibrated to the exact W.C. rating required for the \u003cstrong\u003eLC350TM400558\u003c\/strong\u003e.
