OEM Carrier Pressure Switch Assembly w/Bracket — HK06WC069 for Model PG8JAA066135ABJA

This is the genuine OEM pressure switch assembly with mounting bracket for the Carrier PG8JAA066135ABJA gas furnace. The pressure switch is a normally-open safety device that monitors negative pressure (draft) created by the inducer blower motor. Once the inducer establishes sufficient airflow, the diaphragm inside the switch closes, signaling the control board to proceed to ignition. If this switch fails, becomes stuck open, or loses its calibrated set point, the furnace control board will lock out on a pressure switch fault — typically before the igniter is ever energized — leaving you with no heat.

• OEM vs Generic: OEM switches are factory-calibrated to the exact water column (W.C.) set point for this furnace. Aftermarket units often use wider tolerances, risking nuisance lockouts or — worse — allowing draft faults to go undetected.
