OEM Carrier Pressure Switch HK06WC061 for Model CP48P548P503011CP

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier CP48P548P503011CP packaged unit. The pressure switch is a critical safety device that monitors negative pressure created by the inducer draft motor to confirm adequate airflow before allowing the ignition sequence to proceed. When this switch fails, the control board cannot verify safe venting conditions and the system will lock out — resulting in no heat and a fault code indicating a pressure switch error.

• Specs: OEM-matched W.C. (water column) rating | 24V control circuit compatible | Single-pole normally open (N.O.) configuration | Factory-calibrated trip point for CP48P548P503011CP inducer performance
• OEM vs Generic: This OEM switch is factory-calibrated to the exact W.C. rating required by the Carrier CP48P548P503011CP. Aftermarket pressure switches with incorrect trip points can cause nuisance lockouts or — more dangerously — allow the unit to fire under unsafe draft conditions. OEM is strongly recommended for this safety-critical component.
• Install difficulty: 3/5 — Disconnect power before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (recommended to verify switch operation post-install). Inspect inducer hose and port for blockage or cracks before replacing the switch, as blocked ports are a common root cause of switch failure.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
