OEM Carrier Pressure Switch Assembly with Bracket — HK06WC069 for Model PG8MAA048090ACJA

The Carrier HK06WC069 is the factory OEM pressure switch assembly with integrated mounting bracket for the PG8MAA048090ACJA gas furnace. The pressure switch monitors negative pressure created by the draft inducer motor to confirm safe venting conditions before allowing the ignition sequence to proceed. When this switch fails or sticks open, the furnace control board will lock out the ignition cycle — leaving you with a blower that runs but no heat, often accompanied by a fault code indicating a pressure switch error. A clogged hose, failed inducer, or a faulty switch are the most common culprits; always inspect the hose and inducer before condemning the switch.

• Specs: 3" Water Column (W.C.) set point | SPST (Single-Pole, Single-Throw) | Normally open | Factory Authorized Part with mounting bracket included — exact drop-in replacement, no modifications needed
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP). OEM switches are calibrated to the precise W.C. rating required by the PG8MAA048090ACJA's venting design. Aftermarket switches often carry wider tolerances that can cause nuisance lockouts or, worse, fail to detect unsafe venting conditions.
• Install Difficulty: 2/5 — Disconnect power before servicing. Tools needed: 1/4" nut driver, flat-head screwdriver, and a manometer (recommended to verify inducer draft post-install). Label and photograph hose connections before removal. Inspect rubber hose for cracks or blockages before installing the new switch.
