The pressure switch proves that the inducer motor has established adequate draft before allowing the control board to proceed with ignition. When it fails — or the hose, port, or diaphragm is compromised — the furnace will lock out during the pre-purge cycle, leaving you with no heat and typically a diagnostic fault code indicating a pressure switch failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Cut-out set point: \u003cstrong\u003e6.5\" WC (inches of water column)\u003c\/strong\u003e | SPST configuration | Suitable for air, natural gas, or LP gas applications | Mounts horizontally or vertically\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers Covered:\u003c\/strong\u003e \u003cstrong\u003eHK02LB008\u003c\/strong\u003e (Gas Pressure Switch) | \u003cstrong\u003eHK06WC091\u003c\/strong\u003e (Pressure Switch) | \u003cstrong\u003eHK06WC100\u003c\/strong\u003e (Pressure Switch w\/ Bracket) — all are factory OEM Carrier components for this platform.
