OEM Carrier Pressure Switch Assembly w/Bracket — HK06WC069 for Model PG8MAA048110ACJA
This is the genuine OEM pressure switch assembly with mounting bracket, part number HK06WC069, factory-specified for the Carrier PG8MAA048110ACJA gas furnace. The pressure switch is a normally-open safety device that monitors negative pressure generated by the inducer motor during the pre-purge cycle. Once the inducer establishes sufficient draft, the switch closes and signals the integrated furnace control board to proceed with ignition. When this switch fails — or the hose, port, or inducer motor connected to it degrades — the furnace will lock out before ignition, display a pressure switch fault code, and deliver no heat.

OEM vs Generic: This is the genuine Carrier OEM part, manufactured to exact factory tolerances. Generic aftermarket switches (available separately at lower cost) often carry ±10–15% W.C. set point variance, which can cause nuisance lockouts or — more dangerously — fail to trip under true fault conditions. For a safety-critical device like a pressure switch, OEM is strongly recommended.

Install Difficulty: 2/5 — Straightforward swap on most technicians' scales. Turn off power and gas before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Inspect and blow out the rubber hose port before installing the new switch — a clogged hose is a leading cause of false pressure switch failures. Always verify proper inducer operation after replacement.
