OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA048110ABJA

This is the genuine OEM Carrier Pressure Switch Assembly with Bracket (part number HK06WC069), the factory-specified replacement for Carrier model PG8JAA048110ABJA gas furnaces. The pressure switch is a normally-open safety device that monitors negative pressure (vacuum) generated by the inducer motor during the pre-purge cycle. Once the inducer proves sufficient draft, the pressure switch closes and signals the control board to proceed with ignition. When it fails — or when the hose, port, or inducer are at fault — the furnace locks out on a pressure switch fault code, and you get no heat.

• Specs: Single-stage pressure switch | Opening setpoint: -0.27" W.C. | Max make: -0.42" W.C. | Includes factory-matched mounting bracket | OEM part number HK06WC069
• OEM vs Generic: This is a genuine Carrier OEM assembly with the correct W.C. rating and bracket geometry pre-installed. Aftermarket substitutes often ship without the bracket and may carry a ±15% W.C. tolerance, risking nuisance lockouts or unsafe draft conditions.
• Install difficulty: 2/5 — Shut off gas and power before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (recommended for verification). Photograph hose routing before disconnecting. Always inspect the rubber hose and port for cracks or blockage before condemning the switch.
