OEM Carrier Pressure Switch HK06WC061 for Model LC348LC400283

This OEM pressure switch (part number HK06WC061) is the factory-specified replacement for the Carrier LC348LC400283 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 fails stuck open or closed — the control board will lock out heating entirely, leaving you with a furnace that powers on but never fires. Common symptoms include a flashing fault code indicating a pressure switch error, the inducer running continuously with no ignition attempt, or a furnace that shuts down immediately after startup.

• Specs: OEM part number HK06WC061 | Factory-calibrated W.C. (water column) rating | Single-port pressure switch | Designed for Carrier LC348LC400283 inducer assembly
• OEM vs Generic: OEM pressure switches are calibrated to exact water column specifications for your specific furnace model. Generic alternatives often carry broader tolerances that can cause nuisance lockouts or — more dangerously — fail to detect a true draft failure, making OEM the only safe choice for this safety-critical component.
• Install difficulty: 3/5 — Shut off gas and power before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, manometer (to verify W.C. after install). Inspect the rubber hose port for cracks or blockage before installing the new switch, as a clogged hose is often the root cause of switch failure.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier LC348LC400283 furnace. Always cross-reference the W.C. rating printed on your existing switch with the replacement before installation. If you need fitment confirmation, our HVAC parts specialists are available to verify compatibility before you order — no guesswork required.
