OEM Carrier LP Gas Pressure Switch (HK02LB008 / HK06WC091) for Model PG8JAA060155AEJA

This OEM Carrier LP gas pressure switch is the factory-specified replacement for the Carrier PG8JAA060155AEJA packaged gas furnace. The pressure switch monitors inducer motor operation, proving that the draft blower is creating sufficient negative pressure before allowing the gas valve to open. When it fails or sticks open, the furnace control board cannot confirm safe venting conditions — resulting in a no-ignition lockout, typically with a diagnostic fault code indicating a pressure switch failure before or during the ignition sequence.

• Specs: 6.5" W.C. cutout pressure | SPST normally-open configuration | Compatible with LP (propane) and natural gas applications | Mounts horizontally or vertically | OEM Part Numbers: HK02LB008, HK06WC091
• OEM vs Generic: This is a genuine Carrier OEM pressure switch calibrated to the exact factory setpoint. Aftermarket switches frequently carry wider pressure tolerances, risking nuisance trips or, worse, failing to detect unsafe draft conditions — compromising both reliability and safety.
• Install difficulty: 2/5 — Power down and lock out the furnace before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, and a manometer for setpoint verification. Photograph or label the hose and wiring connections before disconnecting. Swap the rubber sensing hose and spade connectors, then confirm the inducer pressure reading before restoring power.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
