The pressure switch monitors gas supply pressure and proves safe operating conditions before allowing the control board to proceed with the ignition sequence. When this switch fails or drifts out of calibration, the furnace will enter lockout mode — refusing to ignite even though the inducer motor is running — because the control board never receives confirmation that safe gas pressure is present. Common symptoms include a furnace that attempts ignition and then shuts down, a flashing fault code on the control board indicating a pressure switch failure, or a unit that runs the inducer briefly but never moves forward to the heating cycle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK02LB008 (LP Gas Pressure Switch) and HK06WC091 (Pressure Switch High Fire) — both factory-matched to the \u003cstrong\u003ePG8JEA024045ACJA\u003c\/strong\u003e unit's control circuit requirements.
