OEM Carrier LP Gas Pressure Switch 6.5" W.C. for Model PG8MAA024070AGJA

This OEM Carrier gas pressure switch is the factory-specified replacement for the Carrier PG8MAA024070AGJA packaged gas unit. The pressure switch monitors gas supply pressure to the burner assembly, opening or closing the control circuit when the measured pressure reaches the factory-set cutout threshold. When this switch fails or drifts out of spec, the furnace or packaged unit will typically lock out before completing a full ignition sequence — leaving your system with no heat and a fault code pointing to a pressure or proving failure.

• Specs: Cutout pressure: 6.5" W.C. (inches water column) | Suitable for LP (propane) and natural gas applications | Mounts horizontally or vertically | Factory-matched setpoint for PG8MAA024070AGJA
• OEM Part Numbers: Primary — HK02LB008 (LP Gas Pressure Switch) | Also fits applications using HK06WC091 (Pressure Switch) and HK06WC100 (Pressure Switch w/ Bracket) — verify your unit's existing switch configuration before ordering

Professional installation recommended if unfamiliar with gas appliance service.
