OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA036045ABJA

This is the genuine OEM Carrier Pressure Switch Assembly with Bracket (part number HK06WC069), the factory-specified replacement for the Carrier PG8JAA036045ABJA packaged gas furnace. The pressure switch is a critical safety and sequencing component — it monitors negative pressure produced by the inducer blower motor to confirm proper venting before allowing the ignition sequence to proceed. When the switch fails or sticks, the control board receives no confirmation signal and the furnace will lock out, resulting in a no-heat call with a flashing fault code indicating a pressure switch or inducer fault.

• Specs: .27" W.C. break / .42" W.C. max make | Single-stage | Includes factory mounting bracket | Honeywell IS20205-4021 internals | Genuine OEM assembly
• OEM vs Generic: This OEM assembly includes the factory-matched bracket and uses exact W.C. (water column) ratings calibrated for the PG8JAA036045ABJA inducer. Aftermarket switches frequently ship with incorrect trip points, causing nuisance lockouts or unsafe operation.
• Install difficulty: 2/5 — Power down the furnace and confirm zero voltage at the control board before proceeding. Tools needed: 1/4" nut driver, flathead screwdriver, and a digital manometer (recommended for verification). Disconnect the hose port and two wiring harness terminals, swap the bracket-mounted assembly, and re-verify operation through a full heat cycle.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
