This normally-open switch monitors draft-inducer vacuum and closes when adequate airflow is confirmed, permitting the ignition sequence to proceed. If venting is blocked or the inducer is weak, the switch stays open and locks out the burners — protecting against incomplete combustion and flue-gas spillage. A failed switch is a leading cause of furnace no-heat and repeated ignition lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20197311\u003c\/li\u003e\n\u003cli\u003ePart Type: Air Pressure \/ Draft Switch\u003c\/li\u003e\n\u003cli\u003eSet Point: -0.60 in.
