OEM Carrier Pressure Switch HK06WC061 for Model CP48P448P406010CP

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier CP48P448P406010CP packaged unit. The pressure switch is a critical safety component in the inducer circuit — it monitors negative air pressure produced by the draft inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks, the control board cannot verify safe flue conditions and will lock out the heating cycle entirely, leaving you with a no-heat call and a flashing fault code indicating a pressure switch error.

• Specs: OEM part number HK06WC061 | Factory-rated W.C. (water column) set point matched to Carrier CP48P448P406010CP specifications | Single-port or dual-port configuration per OEM design | SPST normally open contact
• OEM vs Generic: OEM pressure switches use factory-calibrated diaphragms with exact W.C. trip points. Aftermarket alternatives often carry wider tolerances that can cause nuisance lockouts or — more dangerously — allow operation under inadequate draft conditions.
• Install difficulty: 3/5 — Requires disconnecting 24V wiring harness, removing rubber hose(s) from the inducer housing or collector box, and unmounting the switch. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, manometer (recommended to verify W.C. on reinstall). Always confirm gas and power are off before servicing.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
