OEM Carrier Pressure Switch HK06WC061 for Model LC3:50HE400814——

This is the factory OEM pressure switch (part number HK06WC061) designed as a direct replacement for the Carrier LC3:50HE400814—— packaged unit. The pressure switch is a critical safety component that monitors negative pressure created by the draft inducer motor. It confirms that proper airflow and venting are established before allowing the control board to initiate the ignition sequence. When this switch fails — whether stuck open or closed — the furnace or packaged unit will enter a lockout condition, refusing to advance past the inducer stage and leaving you with no heat.

• Specs: OEM part number HK06WC061 | Calibrated W.C. (water column) rating factory-matched to LC3:50HE400814—— | Single-port or dual-port configuration per OEM spec | SPST switching action
• OEM vs Generic: This is the genuine Carrier OEM switch, precision-calibrated to the exact water column rating required by your unit. Aftermarket pressure switches often carry wider W.C. tolerances that can cause nuisance lockouts or, worse, allow the system to fire under unsafe venting conditions.
• Install Difficulty: 2/5 — Power down and lock out the unit before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Inspect the rubber hose and port for cracks or blockages before installing the new switch — a clogged port is a frequent root cause of switch failure.
