OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA066110ABJA

This is the genuine OEM Carrier pressure switch assembly with integrated mounting bracket, part number HK06WC069, factory-specified for the Carrier PG8JAA066110ABJA gas furnace. The pressure switch is a normally-open safety device that monitors negative pressure created by the inducer motor. Once the inducer establishes proper draft, the switch closes — signaling the control board to proceed with ignition. When this switch fails, the furnace will lock out before the ignition sequence ever begins, leaving you with no heat and a flashing diagnostic fault code.

• Specs: Single-stage draft inducer pressure switch | Opening set point: -0.27" W.C. | Max make: -0.42" W.C. | Includes factory mounting bracket | OEM part number HK06WC069 (also referenced as HK06WC069A)
• OEM vs Generic: This is a genuine Carrier OEM assembly — not an aftermarket clone. Factory-calibrated to exact W.C. specifications, ensuring the control board receives accurate inducer-prove signals. Generic switches often carry ±10–15% W.C. tolerance variance, risking nuisance lockouts or unsafe ignition attempts.
• Install Difficulty: 2/5 — De-energize the furnace at the disconnect before starting. Tools needed: 1/4" nut driver, flathead screwdriver, and a manometer (recommended to verify draft pressure post-install). Disconnect the rubber hose and two wiring terminals, unbolt the old bracket, and mount the new assembly. Always inspect the pressure port hose for cracks or blockages before installing the new switch.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
