This normally-open (N.O.) switch is calibrated to close at a set point of \u003cstrong\u003e-0.60\" water column (WC)\u003c\/strong\u003e, proving adequate combustion-air and vent draft before the ignition sequence is allowed to proceed. A failing pressure switch is one of the most common causes of a furnace that ignites briefly then shuts down, or that fails to light at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Normally Open (N.O.) air-proving \/ draft pressure switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet point:\u003c\/strong\u003e -0.60\" WC (negative pressure)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Goodman GCH91155DXAE gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Verifies inducer draft \u0026amp; blocked-vent safety\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Direct OEM replacement — plug-and-play\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Our genuine OEM 20197311 switch is factory-calibrated to the exact -0.60\" WC trip point Goodman specifies for this cabinet. Generic switches often carry looser tolerances that can cause nuisance lockouts or, worse, allow ignition under poor-draft conditions. For a safety device, matching the OEM calibration is strongly recommended.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty: Easy (1\/5).\u003c\/strong\u003e Replacement typically takes 10–15 minutes: power down the furnace, disconnect the two spade terminals and the rubber pressure tube, unscrew the mounting screws, and reverse for the new switch. No special tools required. Always confirm power is off at the breaker before servicing.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058057363827,"sku":"GOODMAN-20197311","price":32.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-0-60-wc-n-o-pressure-switch-for-gch91155dxae-20197311","provider":"National HVAC Parts","version":"1.0","type":"link"}
