OEM Carrier Pressure Switch HK06WC061 for Model CP48P448P405510CP

This is the genuine OEM replacement pressure switch (part number HK06WC061) for the Carrier CP48P448P405510CP packaged unit. The pressure switch is a critical safety component that proves the inducer motor is generating adequate negative pressure (draft) before allowing the control board to advance the ignition sequence. When this switch fails, the furnace or packaged unit will lock out prior to ignition — often displaying a fault code indicating a pressure switch or draft fault. A faulty switch is one of the most common causes of a no-heat call that has nothing to do with the gas valve or igniter.
