OEM Carrier Pressure Switch HK06WC061 for Model LC350TM400568

This OEM pressure switch (part number HK06WC061) is the factory-specified replacement for the Carrier LC350TM400568 furnace. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor before allowing the ignition sequence to proceed. If the switch fails to close — or is stuck open — the control board will lock out the furnace, resulting in no heat and often a diagnostic fault code indicating a pressure switch fault.

• Specs: OEM part number HK06WC061 | Factory-calibrated W.C. (water column) rating | Single-port pressure switch | 24V control circuit compatible | Designed for Carrier LC350TM400568 induced-draft gas furnace
• OEM vs Generic: This is a genuine OEM Carrier pressure switch, calibrated to exact factory W.C. specifications. Aftermarket substitutes often carry looser pressure tolerances, which can cause nuisance lockouts or — more dangerously — allow ignition under unsafe draft conditions.
• Install difficulty: 2/5 — Shut off gas and power at the disconnect before beginning. Tools needed: flathead screwdriver, needle-nose pliers, and a manometer (recommended to verify draft pressure). Photograph hose routing and wiring before disconnecting. Inspect the rubber hose for cracks or blockages before installing the new switch.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our warehouse.
