Answer: How Do I Know If My Furnace Gas Valve Is Bad?
Signs of a failing gas valve include: the furnace is not producing heat despite the burners not firing (the gas valve is not opening to allow gas flow), but you can hear the ignitor clicking or glowing; a humming sound from the gas valve area that is louder than normal; the furnace fires but the flame is yellow, uneven, or lazy instead of sharp and blue — indicating the valve is not metering gas correctly; the gas valve has visible corrosion or damage; intermittent operation where the furnace works sometimes but not consistently; or error codes on the control board indicating a gas valve circuit fault. Gas valve replacement should only be performed by a licensed gas fitter — it involves working with gas under pressure and requires proper pressure adjustment after installation.
