OEM Carrier Pressure Switch Assembly w/Bracket HK06WC069 for Model PG8MAA048135ABJA

This is the genuine OEM Carrier pressure switch assembly (part number HK06WC069), the factory-specified replacement for the Carrier PG8MAA048135ABJA gas furnace. The pressure switch monitors negative pressure created by the inducer draft motor to verify that proper venting airflow is established before allowing the control board to advance to the ignition sequence. When this switch fails — or when the hose, port, or inducer is partially obstructed — the furnace will lock out before ignition, typically displaying a fault code indicating a pressure switch fault or stuck-open condition. This assembly ships with the factory mounting bracket for a drop-in replacement with no additional hardware required.

• Specs: 0.27" W.C. break / 0.42" W.C. max make | Single-stage operation | Includes factory mounting bracket | Genuine OEM part — not an aftermarket equivalent
• OEM vs Generic: OEM pressure switches are calibrated to exact W.C. (water column) trip points from the factory. Aftermarket units frequently carry wider tolerances, risking nuisance lockouts or — worse — failure to detect a true venting fault, which is a carbon monoxide safety concern.
• Install difficulty: 2/5 — Shut off gas and power before servicing. Locate the switch on or near the inducer housing. Disconnect the rubber hose and wiring harness, unmount the bracket, and reverse to install. Tools needed: 1/4" nut driver, needle-nose pliers. Inspect the hose and port for cracks or blockages before replacing the switch.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from stock.
