This \u003cstrong\u003enormally open (NO)\u003c\/strong\u003e switch is calibrated to trip at \u003cstrong\u003e-0.60 inches of water column (WC)\u003c\/strong\u003e. It confirms that the inducer\/draft blower is establishing proper combustion airflow and venting before the control board permits the gas valve to open — a critical step that prevents unsafe firing if the vent is blocked or the inducer fails.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 20197311\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Set Point:\u003c\/strong\u003e -0.60\" WC (negative pressure)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Air Pressure \/ Draft Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Fit:\u003c\/strong\u003e ACSH961155DXAA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003ePressure switches are \u003cstrong\u003eapplication-specific by set point and polarity\u003c\/strong\u003e. The factory OEM 20197311 is matched precisely to this furnace's static pressure, ensuring reliable proving and ignition. Generic switches with a different set point or contact configuration can cause intermittent no-heat lockouts, short cycling, or — worse — bypass a genuine venting fault. We strongly recommend OEM for any safety control.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (2\/5).\u003c\/strong\u003e Disconnect power, label and remove the two electrical terminals and the rubber sensing hose, unscrew the mounting screws, and install the replacement in the same orientation. Reconnect the hose without kinks. Allow 20–30 minutes. If the new switch trips immediately, inspect the hose, inducer, and condensate trap for blockage before assuming a defective part.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057456791923,"sku":"GOODMAN-2356","price":39.54,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-0-60-in-wc-no-pressure-switch-for-acsh961155dxaa-20197312","provider":"National HVAC Parts","version":"1.0","type":"link"}
