This normally-open (NO) switch confirms that the induced-draft blower is establishing proper venting before the control board allows ignition — a critical safety interlock that prevents the furnace from firing without adequate flue draft.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20197308\u003c\/li\u003e\n\u003cli\u003eTrip Setpoint: -0.10\" WC (water column)\u003c\/li\u003e\n\u003cli\u003eContact Configuration: Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003eFunction: Draft \/ vent air proving switch\u003c\/li\u003e\n\u003cli\u003eFits: AMH950905DXAE and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003ePressure switches are safety devices, and setpoint accuracy is everything. This factory 20197308 is calibrated and stamped to the exact -0.10\" WC threshold the AMH950905DXAE control logic expects. Generic switches with the wrong setpoint cause short cycling, lockouts, or — worse — allow firing under poor draft conditions. Always match OEM for proving switches.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — about 20–30 minutes.
