Working in concert with the ignition control and safety circuit, it opens on a call for heat, delivers gas at the correct manifold pressure, and shuts off instantly when the sequence ends or a fault is detected — the heart of safe, reliable combustion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e When a gas valve fails you may notice no ignition at all, a burner that lights weakly or unevenly, delayed ignition with a \"whoomp,\" clicking with no gas flow, or a furnace that fails to maintain temperature. A valve stuck closed leaves you without heat, while erratic operation and gas odors demand immediate attention.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The \u003cstrong\u003eY8120\u003c\/strong\u003e is calibrated to your furnace's exact pressure and voltage requirements and is engineered to integrate with Lennox safety controls. Universal valves may require adapters, deliver incorrect manifold pressure, or fail agency-listing requirements for your appliance. Installing the factory-specified valve restores precise fuel control, preserves safe operation, and keeps your Lennox system within its rated performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081077473651,"sku":"LNX-Y8120","price":169.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-gas-valve-y8120","provider":"National HVAC Parts","version":"1.0","type":"link"}
