Rated at \u003cstrong\u003e-0.10 in. w.c., normally open (NO)\u003c\/strong\u003e, this switch verifies that the inducer draft motor is pulling proper airflow before the furnace allows ignition. If venting is blocked or the inducer underperforms, the switch keeps its contacts open and prevents burner operation — a critical protection against carbon-monoxide risk.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20197308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetpoint:\u003c\/strong\u003e -0.10 in. w.c.
