OEM Carrier Pressure Switch HK06WC061 for Model LC350HE401231

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier LC350HE401231 furnace. 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 this switch fails or becomes stuck, the control board cannot verify safe flue conditions, resulting in a no-heat lockout — often with a fault code indicating a pressure switch error. Common symptoms include the inducer motor running continuously with no ignition, or the furnace cycling off immediately after startup.

• OEM vs Generic: This OEM switch is precision-calibrated to the exact water column rating required by Carrier engineering. Aftermarket substitutes may use off-spec trip points, causing nuisance lockouts or — more dangerously — failing to detect true venting faults.
