OEM Carrier Pressure Switch HK06WC061 for Model N6A48NG481824

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier N6A48NG481824 packaged gas/electric unit. The pressure switch is a critical safety component that monitors negative air pressure created by the induced draft blower. Once the blower reaches proper speed and airflow is confirmed, the pressure switch closes and signals the control board to proceed with the ignition sequence. When this switch fails — whether it sticks open, sticks closed, or develops a cracked hose connection — the furnace or packaged unit will lock out before ignition, leaving you with no heat and often a flashing fault code indicating a pressure switch error.

• Specs: OEM-rated W.C. (water column) pressure setting factory-matched to N6A48NG481824 | Single-port design | 1/4" Santoprene hose fitting | 24V control circuit compatible
• OEM vs Generic: The OEM HK06WC061 switch is calibrated to the exact W.C. rating required by this unit. Aftermarket switches often carry wider tolerances that can cause nuisance lockouts or, worse, allow unsafe operation with a compromised venting system.
• Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a flashlight. Inspect the rubber hose and condensate port for blockages before replacing the switch — a clogged hose is a common root cause of switch failure.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship the same business day from our climate-controlled parts warehouse.
