Rated at -0.60 inches water column (WC) and normally open (NO), it confirms the induced-draft blower is establishing proper venting before the control board allows ignition. When the inducer pulls the correct negative pressure, the switch closes and the ignition sequence proceeds — a core safety interlock that prevents firing without adequate flue draft.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20197310\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Point:\u003c\/strong\u003e -0.60\" WC (water column)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Induced-draft \/ venting proof\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Fit:\u003c\/strong\u003e GMH950904CXAB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003ePressure-switch set point is safety-critical and model-specific. The genuine Goodman -0.60\" WC switch is calibrated to this furnace's inducer and venting design, with the correct hose barb and NO contacts. A generic switch with the wrong set point or action can prevent ignition or, dangerously, allow firing with poor venting.
