This normally-open (N.O.) switch senses the -0.40\" water-column vacuum created by the induced-draft blower and closes to prove proper venting airflow before the ignition sequence can proceed. If the vent is blocked or the draft motor fails, the switch stays open and safely locks out the furnace, preventing dangerous combustion conditions.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eActuation setpoint: -0.40\" WC (water column)\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally Open (N.O.)\u003c\/li\u003e\n\u003cli\u003eFunction: Vent \/ draft airflow proving switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370126\u003c\/li\u003e\n\u003cli\u003eEquipment: Furnace (induced draft)\u003c\/li\u003e\n\u003cli\u003ePrimary fit: Goodman GUP115-5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch matches the factory pressure setpoint and hose-port geometry exactly, ensuring reliable ignition and no nuisance lockouts.
