OEM Carrier Pressure Switch Assembly w/Bracket (HK06WC069) for Model PG8JAA036045ADJA

This is the factory-specified OEM pressure switch assembly for the Carrier PG8JAA036045ADJA gas furnace. The pressure switch monitors negative air pressure generated by the inducer motor to confirm proper draft before allowing the ignition sequence to proceed. When it fails or sticks open, the control board detects the fault and locks out the furnace — resulting in a no-heat call, a flashing fault code, or a furnace that attempts to start but shuts down immediately before ignition. This assembly ships with the factory mounting bracket pre-attached, making it a direct drop-in replacement with no fabrication required.

• Specs: Single-stage draft pressure switch | Set point: -0.27" W.C. break / -0.42" W.C. max make | Includes factory mounting bracket | OEM part number: HK06WC069
• OEM vs Generic: This is a genuine Carrier OEM part, calibrated to exact factory set-point tolerances. Aftermarket switches frequently deviate from rated W.C. thresholds, causing nuisance lockouts or — worse — failing to detect a true draft loss condition, creating a safety risk.
• Install Difficulty: 2/5 — Shut off power and gas before beginning. Tools needed: 1/4" nut driver, Phillips screwdriver, needle-nose pliers. Disconnect the rubber hose and two-wire Molex connector, unbolt the old bracket assembly, and reverse the process. Always inspect the rubber hose and hose port for cracks, blockage, or moisture before reinstalling.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for the Carrier PG8JAA036045ADJA gas furnace. This part is also cross-referenced for select Bryant and Payne furnace models sharing the same inducer/pressure switch configuration — verify your model number and existing switch W.C. rating on the data plate before ordering.
