This normally-open (NO) air-proving switch monitors negative pressure in the combustion venting system and closes at a set point of \u003cstrong\u003e-0.37 inches of water column (WC)\u003c\/strong\u003e, allowing the ignition sequence to proceed only when the inducer draft is verified. A failed or drifting pressure switch is one of the most common causes of a furnace that ignites and quickly shuts off, or that locks out with a pressure-switch fault code.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20197312\u003c\/li\u003e\n\u003cli\u003eType: Single-stage, Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003eSet Point: -0.37\" WC\u003c\/li\u003e\n\u003cli\u003eApplication: Draft\/pressure proving on induced-draft gas furnaces\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMH950905DXAB and related 95% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eConnection: Single hose port with spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the factory-specified OEM switch, calibrated to the exact trip point your furnace's control board expects. Universal or generic switches often carry a different set point, which can cause nuisance lockouts or, worse, allow ignition under unsafe draft conditions. For a safety-critical air-proving component, we strongly recommend OEM.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDifficulty: Easy (DIY-friendly, 15–20 min).\u003c\/strong\u003e Disconnect power, note the hose and wire routing, transfer the tubing and spade terminals to the new switch, and remount.
