OEM Carrier Pressure Switch HK06WC061 for Model CP48P548P510010CP

This is the factory OEM replacement pressure switch (part number HK06WC061) designed specifically for the Carrier CP48P548P510010CP packaged unit. The pressure switch is a critical safety component in the combustion circuit — it monitors the negative pressure generated by the inducer draft motor to confirm adequate airflow before allowing ignition to proceed. When this switch fails or sticks, the control board cannot verify safe draft conditions and will lock out the system before any heating cycle can begin. Common symptoms include a furnace or packaged unit that attempts to start but never reaches ignition, an inducer motor that runs continuously without progressing to the next heat sequence, or an error code indicating a pressure switch fault on the control board.

• Specs: OEM part number HK06WC061 | Factory-rated W.C. (water column) setpoint matched to CP48P548P510010CP specifications | Single-port or dual-port configuration per OEM design | Direct plug-and-play harness connection
• OEM vs Generic: This is the genuine Carrier OEM pressure switch, calibrated to the exact W.C. rating required by the CP48P548P510010CP. Aftermarket switches with mismatched trip points can cause nuisance lockouts or, more dangerously, allow ignition under unsafe draft conditions — always use OEM on safety-critical components.
• Install Difficulty: 2/5 — Straightforward swap accessible from the blower/heat exchanger compartment. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers for hose barb removal. Always power down the unit and verify zero voltage before disconnecting the harness. Inspect the rubber pressure hose for cracks or blockages before installing the new switch.
