It works alongside the furnace's other draft controls to confirm proper inducer operation and a clear flue before the ignition sequence begins.\u003c\/p\u003e\u003cp\u003eThis normally open switch closes when the correct negative pressure is sensed. If it fails to close — due to a blocked flue, weak inducer, clogged drain, or a bad switch — the control board halts ignition and reports a fault, resulting in a no-heat condition. Restoring the correct switch keeps the safety chain intact.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip point:\u003c\/strong\u003e -.10 in. w.c.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally open (NO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20197308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMVC950453BXAB and compatible AMVC95 furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Proves inducer draft \/ combustion air path\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Genuine 20197308 is factory-calibrated to the precise -.10\" set point and NO configuration the AMVC95 board expects.
