OEM Carrier Pressure Switch HK06WC061 for Model N6D48NG480103

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier N6D48NG480103 packaged gas unit. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When the switch fails or sticks open, the control board cannot verify inducer operation and the furnace locks out — resulting in no heat, a flashing fault code, or a system that attempts ignition repeatedly without firing.

• Specs: OEM-rated water column (W.C.) pressure setpoint | Single-port hose barb connection | 24V control circuit compatible | Factory-matched diaphragm sensitivity for reliable inducer proving
• OEM vs Generic: OEM pressure switches use factory-calibrated diaphragms that trip at the exact W.C. rating specified for your unit. Aftermarket substitutes often carry wider tolerances, which can cause nuisance lockouts in cold weather or — more dangerously — fail to detect a true venting fault.
• Install difficulty: 2/5 — Power down and disconnect the unit at the breaker before beginning. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (to test switch continuity). Disconnect the rubber hose and two wire leads, swap the switch, and confirm continuity closes when inducer is running.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed specifically for the Carrier N6D48NG480103 packaged gas unit. Always verify the W.C. rating printed on your existing switch and cross-reference OEM part number HK06WC061 before ordering. If you have questions about fitment, our HVAC parts specialists confirm compatibility before your order ships — no guesswork required.
