If the burner knob will no longer turn, then the gas valve which the knob is attached to has seized up and needs to be replaced. You can not take the valve apart and try to re-align anything inside because that will result in a gas leak. These valves are not designed to be taken apart. The valve will just need to be replaced I'm sorry to say. Just order the burner valve you need which is part 313-317 on the diagram in the link below.
