OEM Carrier Pressure Switch HK06WC061 for Model CP48P548P504011CP

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier CP48P548P504011CP packaged unit. The pressure switch is a critical safety component that monitors negative pressure created by the induced draft blower, confirming adequate airflow before allowing the control board to proceed with ignition. When this switch fails or becomes stuck open, the furnace or heating system will lock out before ignition — often displaying a fault code related to pressure switch failure — and no heat will be delivered.

• Specs: OEM part number HK06WC061 | Factory-rated W.C. (water column) set point matched to Carrier CP48P548P504011CP | Single-port or dual-port configuration per factory specification | 24V control circuit compatible
• OEM vs Generic: This is a genuine Carrier OEM pressure switch, factory-calibrated to the exact W.C. rating required for your unit.

Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, manometer (recommended to verify draft pressure), and multimeter to confirm switch continuity. Always shut off power at the disconnect before beginning.
