{"product_id":"oem-lennox-gas-valve-12w46","title":"OEM Lennox Gas Valve — 12W46","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e12W46\u003c\/strong\u003e gas valve regulates the flow of natural gas or propane to the burners in your Lennox furnace. Working in concert with the ignition control and safety switches, it opens only when the control board confirms proper draft and calls for heat, then meters gas at the precise pressure your burners require. It is one of the most safety-critical components in the entire heating system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A failing \u003cstrong\u003e12W46\u003c\/strong\u003e gas valve may cause the furnace to run the inducer and igniter but never light the burners, produce weak or uneven flames, or fail to shut off gas cleanly. Clicking without gas flow, delayed ignition, or a burning smell can also indicate a valve that is stuck, worn, or has failed internally.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Gas valves must be matched exactly to the furnace's gas type, pressure rating, and control voltage. Using a non-OEM valve risks improper pressure regulation, gas leaks, or unsafe operation. The OEM \u003cstrong\u003e12W46\u003c\/strong\u003e delivers the factory-set regulation, correct inlet\/outlet fittings, and terminal configuration your Lennox equipment was built around — the safe choice for any gas valve replacement.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081115615603,"sku":"LNX-12W46","price":169.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-gas-valve-assembly-LNX-12W46.jpg?v=1783761214","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-gas-valve-12w46","provider":"National HVAC Parts","version":"1.0","type":"link"}
