OEM Carrier Pressure Switch HK06WC061 for Model LC348TM402772

This OEM pressure switch (part number HK06WC061) is the factory-specified replacement for the Carrier LC348TM402772 furnace. The pressure switch is a critical safety component that monitors the negative pressure generated by the inducer draft motor. Once the inducer reaches the correct airflow, the switch closes and signals the control board to proceed with the ignition sequence. A failed or stuck pressure switch will prevent the furnace from advancing past the inducer stage, resulting in a no-heat lockout condition — often indicated by a diagnostic fault code on the control board.

• Specs: OEM part number HK06WC061 | Factory-calibrated water column (W.C.) rating | Single-port or dual-port configuration matched to LC348TM402772 specifications | 24V control circuit compatible
• OEM vs Generic: This is a genuine OEM Carrier pressure switch, manufactured to exact W.C. tolerances required by the LC348TM402772. Aftermarket substitutes frequently carry wider pressure tolerances, which can cause nuisance lockouts or, worse, allow the furnace to operate under unsafe draft conditions.
• Install Difficulty: 2/5 — Disconnect power before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a manometer (recommended to verify switch trip point after installation). Photograph all tubing connections before removal to ensure correct reassembly.
