What is the wire on the old control.....what terminal is it on??....When replacing old controls the new ones often have different terminals and sometimes incorporate some terminal internally etc....the Wiring Diagram included should be followed exact....if it's working fineit's likely ok....if you have any doubt have it looked at by an expert
