OEM Carrier Pressure Switch Assembly w/Bracket — HK06WC069 for Model PG8MAA036045ACJA

This is the genuine OEM pressure switch assembly with bracket for the Carrier PG8MAA036045ACJA gas furnace. The pressure switch monitors negative pressure created by the inducer motor to confirm adequate draft before allowing the ignition sequence to proceed. When this switch fails or sticks open, the furnace control board cannot verify proper venting, triggering a safety lockout and leaving you with no heat. Common symptoms include the inducer running but the furnace never advancing to ignition, or a persistent pressure switch fault code on the control board.
