This normally-open (NO) switch closes at a negative pressure of \u003cstrong\u003e-0.10 inches of water column (WC)\u003c\/strong\u003e, proving inducer airflow on the low-fire (first-stage) heating cycle. On two-stage condensing furnaces the low-fire and high-fire stages each rely on their own trip point, so this switch works alongside the higher-pressure switch to guarantee safe venting before ignition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSet point: -0.10\" WC (negative), normally open\u003c\/li\u003e\n\u003cli\u003eFunction: low-fire \/ first-stage air-proving safety interlock\u003c\/li\u003e\n\u003cli\u003eFits: GMV950905DXBA and compatible GMV9 two-stage furnaces\u003c\/li\u003e\n\u003cli\u003eConnection: single-tube pressure port with spade terminals\u003c\/li\u003e\n\u003cli\u003ePart type: OEM condensing-furnace pressure switch\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Because -0.10\" WC is a very low, precise trip pressure, an out-of-spec generic switch will chatter or fail to prove low-fire, leaving you stuck on high-fire or in lockout. The genuine Goodman 20197308 is factory-calibrated to your control board's expectations.
