OEM Carrier Pressure Switch Assembly with Bracket (HK06WC069) for Model PG8MAA066110ABJA

This is the factory OEM pressure switch assembly with mounting bracket for the Carrier PG8MAA066110ABJA gas furnace. The pressure switch is a critical safety and sequencing component that monitors negative pressure created by the inducer motor. Once the inducer establishes proper draft, the switch closes its normally-open contacts, signaling the control board to proceed with ignition. If this switch fails — whether stuck open, stuck closed, or due to a ruptured diaphragm — the furnace will lock out before ignition, displaying a fault code and leaving your home without heat.
