This switch confirms the induced-draft blower is producing adequate negative pressure before the control board allows ignition. If the correct vacuum is present, the normally-open contacts close and the sequence proceeds; if venting is blocked or the trap\/inducer is failing, the switch stays open and the furnace safely refuses to fire.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet point:\u003c\/strong\u003e -0.10 inch WC (water column)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally open (NO), single stage\/tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Proves induced-draft airflow before ignition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e Spade terminals + hose\/pressure tap port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GME950403BXAB and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM 20197308 is calibrated to the exact -0.10\" WC trip point and NO configuration this furnace requires. A generic switch with a different set point or normally-closed action can allow ignition under poor-draft conditions or cause chronic no-heat lockouts. For a code-critical safety device, genuine Goodman OEM is strongly recommended.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Easy (1–2 of 5). Disconnect power, pull the rubber hose off the pressure tap, unplug the spade terminals, remove the mounting screw(s), and install the new switch — reattaching the hose without kinks. A manometer verifies the switch is seeing proper draft. Rule out a blocked flue or clogged trap before replacing.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058108121459,"sku":"GOODMAN-11004","price":39.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-pressure-switch-10-wc-no-for-gme950403bxab-20197308","provider":"National HVAC Parts","version":"1.0","type":"link"}
