This is the replacement left front orifice for your gas range. When your range is operating, gas flows through the orifice to the igniter. This part is the orifice itself as well as the metal holder that holds it in place. If you notice a gas smell when your range is on, you could have a loose or damaged orifice. This part fits the front left burner in your range, so make sure you are replacing the correct orifice. This is an OEM part sourced from the manufacturer and is sold individually.
