The large burner is an important component of your hob; most hobs only have one and so they rely on it quite a lot! The larger burner is often referred to as a rapid burner, this is because it cooks your food a lot faster than the other burners on your hob, so it's vitally important if the burner disc is showing signs of wear and tear that you should replace it as soon as possible because this will significantly reduce the burner's performance.
