The Whirlpool W10853432 Range Orifice Spud is an essential component for controlling gas flow in Whirlpool gas ranges. It's a small, metal tube with a precisely designed opening that limits the amount of gas that passes through to a certain burner. The spud ensures that each burner obtains the proper gas pressure for its intended application by providing varied sized orifices. For example, a high-power burner will have a larger opening than a simmer burner. The gas line delivers gas to the range. The gas then passes through the orifice spud, where the precise orifice size regulates the volume of gas permitted through. This controlled flow has a direct impact on the burner's flame size and heat production.
