The pressure switch is a critical safety component that monitors negative pressure created by the draft inducer blower before allowing the ignition sequence to proceed. When it fails or sticks open, the furnace enters a safety lockout — typically displaying a fault code and refusing to fire — even though the inducer motor itself may be running normally.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e Primary: \u003cstrong\u003eHK02LB008\u003c\/strong\u003e (Gas Pressure Switch) | Cross-references: \u003cstrong\u003eHK06WC091\u003c\/strong\u003e (Pressure Switch) and \u003cstrong\u003eHK06WC100\u003c\/strong\u003e (Pressure Switch w\/ Bracket) — verify your unit's existing configuration before selecting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch, calibrated to the exact water column (W.C.) set point required by the PG8JAA048070AGJA.
