OEM Carrier Pressure Switch HK06WC061 for Model LC350LC400467

This OEM pressure switch (part number HK06WC061) is the factory-specified replacement for the Carrier LC350LC400467 furnace. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor. Once the inducer reaches proper speed and airflow, the switch closes to signal the control board that it is safe to proceed with ignition. When this switch fails — whether due to a ruptured diaphragm, stuck contacts, or a blocked sensing port — the furnace will lock out before ignition, leaving you with no heat and typically a diagnostic fault code indicating a pressure switch error.

• Specs: OEM part number HK06WC061 | Factory-calibrated W.C. (water column) rating | Single-port pressure switch | Direct drop-in replacement with matching hose barb and electrical connector
• OEM vs Generic: This is a genuine Carrier OEM pressure switch, calibrated to the exact water column rating required by the LC350LC400467. Aftermarket substitutes often carry looser trip-point tolerances, which can cause nuisance lockouts or, worse, fail to detect a true draft fault — a safety risk.
• Install difficulty: 2/5 — Disconnect power before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a phone or camera to photograph hose and wire routing before removal. Check the rubber sensing hose for cracks or blockages while the panel is open.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our dedicated HVAC parts warehouse.
