The kit includes both the \u003cstrong\u003eHK06NB012 Dual Pressure Switch Assembly\u003c\/strong\u003e and the \u003cstrong\u003eHK02LB008 Gas Pressure Switch\u003c\/strong\u003e, covering the complete inducer-proving circuit. These switches are normally-open safety devices that close only when the inducer motor creates the correct negative pressure (vacuum) in the flue system — confirming safe combustion airflow before allowing ignition to proceed. If either switch fails or a hose cracks, the control board will lock out the furnace before a single spark is attempted. Typical symptoms include a blinking fault code for \"pressure switch stuck open,\" no ignition after inducer start, or a furnace that runs the inducer but shuts off within 30 seconds.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Parts:\u003c\/strong\u003e HK06NB012 Dual Pressure Switch Assembly (2-port, dual-stage proving) + HK02LB008 Gas Pressure Switch (LP\/propane sensing) — both factory-matched water column ratings for the PG95XAT30040AAAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are factory-calibrated to exact W.C. setpoints.
