OEM Carrier Pressure Switch Assembly with Bracket — HK06WC069 for Model PG8MAA048090ADJA

This is the factory OEM Pressure Switch Assembly with Bracket (part number HK06WC069), the exact replacement specified by Carrier for the PG8MAA048090ADJA gas furnace. The pressure switch is a critical safety component in the inducer circuit: it monitors negative pressure (vacuum) generated by the inducer motor to verify proper venting before allowing the ignition sequence to proceed. If this switch fails, the control board will lock out the furnace prior to ignition — resulting in a no-heat call with no error code advancement past inducer startup, or a flashing pressure switch fault code.

• OEM Part Number: HK06WC069 | Factory description: Pressure Switch Assembly with Bracket | Single-stage, normally open | Rated at -0.27" W.C. break / -0.42" W.C. max make
• OEM vs Generic: This is a genuine Carrier OEM assembly including the factory-matched mounting bracket. Aftermarket switches often omit the bracket and may carry wider W.C. tolerances, risking nuisance lockouts or — more dangerously — masking real venting failures.
• Install Difficulty: 2/5 — Shut down the furnace and disconnect power at the breaker before servicing. Tools needed: Phillips and flat-head screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all hose port connections before removal. Inspect the rubber sensing hose for cracks or blockages before installing the new switch.
