The gas valve is the heart of your furnace's combustion system — it regulates the precise flow of natural or LP gas to the burners and opens only on a valid call for heat from the control board, making it a critical safety component. This factory kit includes the correct valve and hardware to restore proper, code-compliant operation.\u003c\/p\u003e\u003cp\u003eCommon symptoms of a failing gas valve include a furnace that ignites intermittently or not at all, burners that fail to stay lit, weak or fluctuating flame, unusual clicking without ignition, or a system that locks out on repeated ignition failures. Because a stuck or leaking valve is a safety hazard, replacement should not be delayed.\u003c\/p\u003e\u003cp\u003eChoosing an OEM Lennox \u003cstrong\u003e45L91\u003c\/strong\u003e ensures exact fitment, correct gas pressure regulation, and full compatibility with your furnace's ignition sequence and safety controls.
