OEM Carrier Pressure Switch HK06WC061 for Model CP48P448P407011CP

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier CP48P448P407011CP packaged heating and cooling unit. The pressure switch is a critical safety device that monitors negative pressure created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails — or the hose, port, or inducer motor connected to it fails — the control board receives no confirmation signal and locks out the system, resulting in a no-heat condition with a pressure switch fault code displayed.

• Specs: OEM part number HK06WC061 | Factory-rated W.C. (water column) set point matched to Carrier CP48P448P407011CP | Single-port design | 24V control circuit compatible
• OEM vs Generic: This is the exact factory-specified switch with a precision W.C. set point calibrated for your unit. Aftermarket pressure switches often use wider tolerance ranges, which can cause nuisance lockouts or — more dangerously — allow ignition under marginal draft conditions. OEM is strongly recommended for this safety-critical component.
• Install difficulty: 2/5 — Power down the unit completely before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Disconnect the rubber hose and two-wire harness, swap the switch, and confirm the hose is free of cracks or blockages before restarting. Always check the inducer motor and vent path if the new switch immediately faults.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day when ordered before cutoff.
