This switch proves that the induced-draft blower is moving combustion air correctly before the furnace allows ignition — a critical safety interlock. A failed switch is a common cause of furnaces that won't fire or that lock out mid-cycle.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 11112501S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Point:\u003c\/strong\u003e -0.33 in.

An OEM 11112501S is factory-calibrated to -.33\" WC, so it trips at precisely the right draft pressure. Generic or mismatched switches risk false lockouts or, worse, allowing ignition without adequate draft. OEM ensures safe, code-compliant operation.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — Disconnect power, unplug the two-wire connector, transfer the rubber hose to the new switch, and mount with the same screws. Most homeowners with basic tools can complete this in 15–20 minutes; verify the hose is free of condensate afterward.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058250432883,"sku":"GOODMAN-14711","price":31.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-33-wc-pressure-switch-for-wgge4348a090mab-11112501s","provider":"National HVAC Parts","version":"1.0","type":"link"}
