It verifies that the inducer\/draft blower is producing adequate airflow before the control board allows the igniter and gas valve to fire. When the inducer proves draft, the normally open contacts close to signal the board. A failed switch, a cracked hose, or a blocked vent commonly shows up as a furnace that runs the inducer but never lights.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSet point: -0.85\" water column (WC)\u003c\/li\u003e\n\u003cli\u003eContact configuration: Normally Open (N.O.)\u003c\/li\u003e\n\u003cli\u003eFunction: Draft \/ vent air-proving switch\u003c\/li\u003e\n\u003cli\u003eCompatible model: Goodman GMNT100-4\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370150\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370150\u003c\/strong\u003e is factory-calibrated to the exact -0.85\" WC set point required by the GMNT100-4 combustion design — the correct set point is essential for safe, reliable ignition.
