OEM Carrier LP Gas Pressure Switch HK02LB008 for Model PG8JEA024045ACJA

This OEM LP gas pressure switch is the factory-specified replacement for the Carrier PG8JEA024045ACJA packaged gas furnace unit. 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.

• OEM Part Numbers: HK02LB008 (LP Gas Pressure Switch) and HK06WC091 (Pressure Switch High Fire) — both factory-matched to the PG8JEA024045ACJA unit's control circuit requirements. Verify your data plate before ordering.
• OEM vs Generic: OEM pressure switches are calibrated to exact water-column (W.C.) cutout specs at the factory. Generic aftermarket units frequently ship with W.C. tolerances that are off by ±15%, causing nuisance lockouts or — worse — failing to protect against unsafe gas pressure conditions.
• Install difficulty: 2/5 — Turn off gas supply and 120V power at the disconnect before starting. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers, and a manometer to verify pressure post-install. Photograph all tubing and wiring connections before disconnecting. Swap hose connections one at a time to avoid misrouting.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered for the Carrier PG8JEA024045ACJA packaged gas furnace. This switch is also used across Bryant and Payne platforms sharing the same control architecture. Always cross-reference your unit's data plate W.C. rating and OEM part number before installation. Have a fitment question?
