The pressure switch monitors the negative pressure (vacuum) created by the inducer blower motor to prove safe combustion airflow before allowing the gas valve to open. If the switch fails or cannot reach its set-point — typically \u003cstrong\u003e6.5\" W.C.\u003c\/strong\u003e — the control board will lock out ignition entirely, leaving you with a furnace that attempts to start and immediately shuts down, or never progresses past the inducer stage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Set-point 6.5\" W.C. | SPST configuration | Rated for LP (propane) and natural gas applications | Compatible with single-stage inducer circuits | Mounts horizontally or vertically\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers Covered:\u003c\/strong\u003e Primary — \u003cstrong\u003eHK02LB008\u003c\/strong\u003e (Gas Pressure Switch) | Also replaces \u003cstrong\u003eHK06WC091\u003c\/strong\u003e (Pressure Switch) and \u003cstrong\u003eHK06WC100\u003c\/strong\u003e (Pressure Switch w\/ Bracket).
