The Whirlpool WPW10206112 is a seemingly tiny but significant component within your Whirlpool gas range, specifically the range burner pilot. The spark that ignites your cooktop initially comes from this pilot burner. Turn a knob to light the main burners, and it will burn a little flame continuously. A bigger flame burns on the stovetop instantaneously when a burner is turned on because gas is flowing close to the pilot flame.A dependable and practical source of ignition for your gas range is provided by this constant pilot flame. With the pilot burner, cooking can begin instantly and safely—unlike with previous models that needed matches or lighters. In addition, a well-maintained pilot burner helps ensure even and steady burner lighting, removing annoying lag times and uneven flames.
