Working in concert with the ignition control board and safety limits, it opens to admit fuel during a heating call and closes instantly when the call ends or a fault is detected — making it one of the most safety-critical components in the entire heating system. This valve is engineered to match the exact pressure regulation, flow rate, and electrical characteristics your Lennox equipment was designed around.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e a furnace that ignites intermittently or not at all, a clicking valve that never opens, delayed ignition with a \"whoomp\" sound, no gas flow despite a call for heat, or a valve that fails to fully close and allows gas to seep through. Erratic regulator pressure and audible buzzing can also signal a worn valve.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e gas valves are life-safety devices, and using the factory-specified Lennox \u003cstrong\u003e78L60\u003c\/strong\u003e guarantees correct manifold pressure, proper shutoff, and full compatibility with your unit's control logic. Aftermarket substitutes risk improper regulation, nuisance lockouts, and voided warranties — with OEM you get rated performance and peace of mind.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081095266675,"sku":"LNX-78L60","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-78L60.jpg?v=1783761296","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-gas-valve-78l60","provider":"National HVAC Parts","version":"1.0","type":"link"}
