OEM Carrier LP Gas Pressure Switch for Model PG8MAA024070AEJA (HK02LB008 / HK06WC091)

This OEM Carrier LP gas pressure switch is the factory-specified replacement for the Carrier PG8MAA024070AEJA packaged gas unit. The pressure switch proves that the draft inducer has established proper airflow before allowing ignition to proceed. When it fails or sticks open, the furnace will lock out before the ignition sequence begins — leaving you with no heat and often a flashing fault code on the control board. Both OEM part numbers HK02LB008 (LP/Gas Pressure Switch) and HK06WC091 (Pressure Switch, High Fire) are covered by this listing and are direct replacements for the PG8MAA024070AEJA.

• Specs: Cut-out pressure 6.5" W.C. | SPST configuration | Suitable for LP gas, natural gas, and air applications | Can be mounted horizontally or vertically for flexible installation
• OEM vs Generic: OEM pressure switches are factory-calibrated to exact W.C. setpoints. Aftermarket switches frequently deviate in cut-in/cut-out tolerances, causing nuisance lockouts or — worse — unsafe ignition timing. OEM is always the safer choice on gas appliances.
• Install Difficulty: 2/5 — Turn off power and gas supply before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a manometer for post-install verification. Always inspect the rubber pressure hose for cracks or blockage before condemning the switch itself.
• Warranty & Shipping: 1-year OEM factory warranty against defects. Orders placed by 3 PM local time ship same business day from our warehouse.
