It confirms proper induced-draft airflow before the furnace allows ignition, and it is a direct fit for the \u003cstrong\u003eGMV951155DXBA\u003c\/strong\u003e two-stage variable-speed condensing furnace and related GMV9-series models.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20197308\u003c\/li\u003e\n\u003cli\u003eSet Point: -.10 in WC (water column)\u003c\/li\u003e\n\u003cli\u003eContact Configuration: Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003eFunction: Induced-draft \/ vent-pressure proving switch\u003c\/li\u003e\n\u003cli\u003ePrimary Fit: Goodman GMV951155DXBA\u003c\/li\u003e\n\u003cli\u003eType: Factory OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003ePressure switches are calibration-critical. The \u003cstrong\u003eOEM 20197308\u003c\/strong\u003e is factory-set to the exact -.10 WC trip point your furnace's control board expects. A generic switch with a slightly different set point or contact type can cause nuisance lockouts, delayed ignition, or a furnace that never fires. Because this component is a safety device, we strongly recommend the OEM part over a universal substitute.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to Moderate (2 of 5).\u003c\/strong\u003e Replacement involves disconnecting the pressure tubing and two spade terminals, then mounting the new switch in the same orientation. Verify the hose is free of condensate and the port faces correctly. Test for proper ignition sequence after installation. If lockout codes persist, have a licensed technician inspect the inducer and venting.\u003c\/p\u003e\u003cp\u003eReplacing a stuck-open or drifted pressure switch restores reliable ignition and clears common furnace fault codes.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058179522931,"sku":"GOODMAN-12886","price":32.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-10-wc-pressure-switch-for-gmv951155dxba-20197308","provider":"National HVAC Parts","version":"1.0","type":"link"}
