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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are factory-calibrated to the exact W.C. rating required by the \u003cstrong\u003ePY3GNA030040NA\u003c\/strong\u003e heat exchanger and inducer assembly.
