OEM Carrier Pressure Switch HK06WC061 for Model LC350TM400696

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier LC350TM400696 furnace. The pressure switch is a critical safety component that monitors the negative pressure (inches of water column) created by the inducer draft motor before allowing the ignition sequence to proceed. If the switch fails to close — or closes prematurely — the control board will lock out the furnace and prevent heating. Common symptoms include a furnace that starts the inducer but never advances to ignition, a flashing fault code indicating a pressure switch error, or a unit that intermittently loses heat during cold weather demand.

• Specs: OEM part number HK06WC061 | Factory-calibrated W.C. (water column) rating | Single-port diaphragm-style pressure switch | Direct factory replacement for Carrier LC350TM400696
• OEM vs Generic: The OEM Carrier pressure switch is precision-calibrated to the exact W.C. rating required by your furnace's inducer assembly. Generic substitutes often carry wider tolerances, risking nuisance lockouts in cold weather or, more dangerously, failure to detect a true blocked-flue condition.
• Install difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a manometer if verifying inducer static pressure. Inspect the rubber hose port for cracks or blockages before installing the new switch, as a deteriorated hose is a common root cause of switch failure.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled parts warehouse.
