The pressure switch monitors negative pressure created by the inducer motor to confirm proper venting before allowing ignition to proceed. When either switch fails — or when a hose, port, or diaphragm degrades — the control board detects an open circuit and locks out the furnace entirely, leaving you with a no-heat call and a blinking fault code. A dual pressure switch assembly replaces both the primary and secondary sensing switches simultaneously, ensuring accurate proving across all firing stages.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK06NB020 (original) | Current OEM replacement: HK06MB020 — \u003cstrong\u003e-0.75\" WC \/ -0.30\" WC\u003c\/strong\u003e dual set-point | Factory-matched diaphragm tolerances\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches use factory-calibrated diaphragms rated to exact water-column specs.
