OEM Carrier Pressure Switch HK06WC061 for Model LC348TM401746

This OEM pressure switch (part number HK06WC061) is the factory-specified replacement for the Carrier LC348TM401746 furnace. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor. When the inducer is running properly, the switch closes and signals the control board to proceed with ignition. A failed pressure switch will prevent the furnace from advancing past the inducer stage, resulting in a no-heat lockout condition — often indicated by a fault code on the control board or a rapidly blinking LED sequence.

• Specs: OEM part number HK06WC061 | Factory-calibrated W.C. (water column) pressure rating | Single-port or dual-port configuration matched to Carrier LC348TM401746 specifications | 24V control circuit compatible
• OEM vs Generic: This is a genuine OEM Carrier pressure switch, factory-calibrated to the exact water column rating required for safe, reliable ignition sequencing. Aftermarket substitutes frequently carry imprecise trip points, leading to nuisance lockouts, failed safety checks, or — more dangerously — ignition attempts under unsafe draft conditions.
• Install difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Inspect the rubber hose connecting the pressure port to the inducer housing for cracks or blockages before installing the new switch, as a damaged hose is a common root cause of pressure switch failure.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
