OEM Carrier Pressure Switch HK06WC061 for Model PY3GNA030040NA

This OEM pressure switch is the factory-specified replacement for the Carrier PY3GNA030040NA packaged gas unit. The pressure switch monitors negative pressure created by the inducer motor to confirm safe draft conditions before allowing the ignition sequence to proceed. When it fails, the furnace or packaged unit will lock out before ignition — often with a diagnostic fault code indicating a stuck-open or stuck-closed pressure switch. You may also notice the inducer running continuously with no heat output.

• Specs: OEM Part Number HK06WC061 | Factory-calibrated water column (W.C.) trip point | Single-port design | 24V control circuit compatible | Direct OEM replacement — no modification required
• OEM vs Generic: OEM pressure switches are factory-calibrated to the exact W.C. rating required by the PY3GNA030040NA heat exchanger and inducer assembly. Off-brand substitutes often carry loose tolerances that can cause nuisance lockouts or, more critically, allow ignition under unsafe draft conditions.
• Install Difficulty: 2/5 — Disconnect power before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers, and a manometer (recommended) to verify W.C. at startup. Photograph hose routing and wiring connections before removal. Swap the pressure hose and two-wire harness, then restore power and confirm normal ignition sequence.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
