The pressure switch monitors the negative pressure (vacuum) created by the draft inducer motor to confirm safe combustion airflow before allowing the gas valve to open. When it fails or sticks open, the furnace will lock out before ignition — leaving you with a blinking error code and no heat. Common symptoms include the inducer running but the furnace never advancing past the pre-purge stage, or a fault code indicating a failed pressure switch.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK02LB008 (Gas Pressure Switch) | HK06WC091 (Pressure Switch High Fire) — both are factory-authorized Carrier\/Honeywell parts covering this model's pressure switch circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e SPST configuration | Rated for LP and natural gas applications | Cut-out pressure set at \u003cstrong\u003e6.5\" W.C.\u003c\/strong\u003e | Mounts horizontally or vertically | Compatible with Carrier, Bryant, and Payne platforms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are factory-calibrated to the exact W.C. setpoint for the \u003cstrong\u003ePG8MEA048070ACJA\u003c\/strong\u003e heat exchanger.
