This normally-open switch proves that the induced-draft blower is establishing adequate negative pressure before the control board allows ignition. If venting is blocked or the inducer is weak, the switch stays open and locks out the burner — a core safety function that prevents combustion without proper draft.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 11177114\u003c\/li\u003e\n\u003cli\u003eSetpoint: -0.50\" WC (water column)\u003c\/li\u003e\n\u003cli\u003eContact Type: Normally Open (NO), single-pole\u003c\/li\u003e\n\u003cli\u003eFunction: Draft \/ air-proving safety switch\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana-compatible)\u003c\/li\u003e\n\u003cli\u003eFits: AMVC950905DXBA and related 2-stage models\u003c\/li\u003e\n\u003cli\u003eCategory: Pressure Switch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003ePressure switches must trip at an exact setpoint.
