OEM Carrier LP Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8MAA024070AFJA

This OEM Carrier LP gas pressure switch is the factory-specified replacement for the Carrier PG8MAA024070AFJA packaged gas unit. The pressure switch is a critical safety device that monitors the gas supply pressure and proves that the inducer motor is operating correctly before allowing ignition to proceed. When this switch fails or sticks, the furnace will enter a lockout condition — typically refusing to fire, cycling off before the burners light, or flashing a fault code indicating a pressure switch error. Both OEM part numbers HK02LB008 (Gas Pressure Switch) and HK06WC091 (Pressure Switch) are covered by this listing and are direct application matches for this model.

• Specs: LP / Propane gas application | Cut-out pressure: 6.5" W.C. | SPST configuration | Fits Carrier, Bryant, and Payne packaged and furnace units | Factory-matched pressure setpoint
• OEM vs Generic: OEM pressure switches are factory-calibrated to exact W.C. specifications. Generic aftermarket switches frequently deviate from setpoint tolerances, causing nuisance lockouts or — more dangerously — allowing ignition under unsafe draft conditions.
• Install difficulty: 2/5 — Shut off gas and power at the disconnect before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, and a short length of replacement vacuum tubing if the original is cracked. Always label hose ports before disconnecting. Verify LP vs. natural gas application on your unit's data plate before ordering.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
