This switch verifies that the induced-draft blower has established proper airflow before the control board energizes ignition. When the inducer pulls the required negative pressure, the normally-open contacts close, proving draft; if draft is insufficient — from a blocked flue, weak inducer, or plugged pressure port — the switch stays open and safely prevents the burner from firing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGenuine OEM Goodman\/Amana part number 20197308\u003c\/li\u003e\n\u003cli\u003eSet point: -0.10 in.
