OEM Carrier LP Gas Pressure Switch for Model PG8MAA060155AGJA

This OEM LP gas pressure switch is the factory-authorized replacement for the Carrier PG8MAA060155AGJA packaged gas unit. The pressure switch monitors the gas supply pressure, cutting out at 6.5" W.C. to protect the heat exchanger and burner assembly. When it fails, the furnace typically enters a hard lockout — no ignition attempt, no heat — often accompanied by a diagnostic fault code pointing to pressure sensing or inducer circuit failure.

• Specs: LP (propane) gas pressure switch | Cut-out set point: 6.5" W.C. | OEM part numbers: HK02LB008 (primary), HK06WC091 (direct cross-reference), HK06WC100 (with bracket) | Cross-reference: GFS3451-4036
• OEM vs Generic: This is a genuine OEM Carrier factory-authorized part. OEM pressure switches are factory-calibrated to exact W.C. tolerances — generic substitutes frequently drift off set-point, causing nuisance lockouts or, worse, unsafe gas-pressure conditions.
• Install difficulty: 2/5 — Shut off gas supply and disconnect power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, manometer (to verify gas pressure post-install). Photograph all wiring and tubing connections before removal. Swap pneumatic tubing to the new switch and reconnect the single-wire harness connector.
• Warranty: 1-year OEM factory warranty. Orders placed by 3 PM local time ship same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MAA060155AGJA packaged gas/electric unit. Also cross-references Bryant and Payne packaged units sharing the HK02LB008 / HK06WC091 / HK06WC100 pressure switch family. Always verify your unit's gas type (LP vs. natural gas) and the W.C. rating on the existing switch before ordering. Our fitment team is available to confirm compatibility before you buy.
