OEM Carrier Pressure Switch Assembly with Bracket for Model PG8JAA036070ACJA

This is the genuine OEM replacement Pressure Switch Assembly with Bracket (part number HK06WC069) for the Carrier PG8JAA036070ACJA gas furnace. The pressure switch is a critical safety component that proves inducer motor operation by detecting the negative pressure (draft) created in the flue system before allowing ignition to proceed. When this switch fails or sticks, the furnace control board receives no confirmation that the inducer is running — locking out the heating cycle entirely. Common symptoms include a furnace that powers on, runs the inducer motor briefly, then shuts down without ever reaching ignition, or a system that flashes a pressure switch fault code on the control board LED.

• Part Specs: OEM Carrier Pressure Switch Assembly | Includes factory-mounted bracket for direct bolt-in installation | W.C. (water column) rating matched to factory specification for the PG8JAA036070ACJA | Single-port hose connection
• OEM vs Generic: This factory OEM unit is calibrated to the exact W.C. trip point required by the Carrier PG8JAA036070ACJA. Aftermarket switches frequently drift in calibration, causing nuisance lockouts or — more dangerously — failing to trip when a true draft problem exists.
• Install Difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a phone/camera to photograph existing hose routing before removal. Swap the pressure hose and two mounting screws; confirm LED fault code clears on first call for heat.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed and factory-specified for the Carrier PG8JAA036070ACJA packaged gas furnace. Always cross-reference the W.C. rating stamped on your existing switch with the rating on this unit before installing. Not sure it fits?
