OEM Carrier Pressure Switch HK06WC061 for Model LC350LC400469

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier LC350LC400469 furnace. The pressure switch is a critical safety component that monitors the negative pressure created by the inducer draft motor. It confirms proper venting airflow before allowing the ignition sequence to proceed. When this switch fails or sticks, the furnace control board will lock out before ignition — leaving you with no heat. Common symptoms include a furnace that runs the inducer motor but never advances to ignition, a blinking fault code indicating a pressure switch error, or a unit that short-cycles repeatedly without producing heat.

• Specs: OEM part number HK06WC061 | Factory-calibrated W.C. (water column) rating | Single-port pressure switch | 24V control circuit compatible | Designed for induced-draft furnace application
• OEM vs Generic: This OEM Carrier pressure switch is factory-calibrated to the exact water column rating required by the LC350LC400469. Aftermarket substitutes often carry looser pressure tolerances, which can cause nuisance lockouts or — more dangerously — allow ignition under insufficient draft conditions, creating a safety risk.
• Install Difficulty: 2/5 — A straightforward swap for experienced DIYers. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, and a digital manometer (recommended to verify draft pressure after install). Always disconnect power before servicing. Inspect the rubber hose port for cracks or blockage before assuming the switch itself has failed.
• Warranty: Backed by a 1-year OEM manufacturer warranty. In-stock and ships same business day from our fulfillment warehouse.
