OEM Carrier Pressure Switch HK06WC061 for Model N6D48NG480100

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier N6D48NG480100 packaged gas unit. The pressure switch is a critical safety device that monitors the negative pressure (measured in inches of water column, W.C.) created by the inducer draft motor before the control board allows ignition to proceed. If the switch fails to close — or sticks open — the furnace or packaged unit will lock out before the ignition sequence ever begins, leaving you with a no-heat condition. Common symptoms include a blinking fault code indicating a pressure switch error, the inducer running continuously without ignition, or the system recycling repeatedly without producing heat.
