It houses two setpoints — \u003cstrong\u003e-.30\" WC\u003c\/strong\u003e and \u003cstrong\u003e-.75\" WC\u003c\/strong\u003e — to independently verify low-fire and high-fire induced-draft airflow before allowing ignition. This gray-bodied switch is a critical combustion safety that prevents firing when venting is blocked or the inducer underperforms.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 11177113\u003c\/li\u003e\n\u003cli\u003eType: Combination (dual) negative-pressure switch\u003c\/li\u003e\n\u003cli\u003eSetpoints: -0.30\" WC and -0.75\" WC (water column)\u003c\/li\u003e\n\u003cli\u003eHousing color: Gray\u003c\/li\u003e\n\u003cli\u003eFunction: Low-fire \u0026amp; high-fire draft proving safety\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMV950704CXBB and select GMV95 two-stage furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman 11177113\u003c\/strong\u003e ships with both setpoints factory-calibrated to spec — essential for a safety component.
