OEM Carrier Pressure Switch HK06WC061 for Model LC350TM400562

This is the genuine OEM pressure switch (part number HK06WC061) factory-specified for the Carrier LC350TM400562 furnace. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor, confirming proper venting before allowing the control board to proceed with ignition. When this switch fails or becomes stuck open, the furnace will lock out before ever reaching the ignition stage — resulting in a no-heat call with the inducer running but no spark or gas flow. A failed pressure switch is one of the most common causes of furnace no-heat diagnostics in the field.

• Specs: Factory-calibrated W.C. (water column) rating matched to Carrier LC350TM400562 | Single-port or dual-port configuration per OEM spec | 24V control circuit compatible | Direct hose and terminal connection — no modification required
• OEM vs Generic: This is a genuine Carrier OEM part carrying the exact pressure threshold calibration for your unit. Aftermarket pressure switches often carry wider trip-point tolerances, which can cause nuisance lockouts or, worse, allow ignition under unsafe draft conditions.
• Install Difficulty: 2/5 — Power down and verify inducer is off before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, and a manometer to verify trip point after install. Inspect hose for cracks or blockages before replacing the switch — a clogged hose port is often the true culprit.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our HVAC parts warehouse.

Compatibility: Designed and calibrated specifically for the Carrier LC350TM400562 furnace.
