Please call an elevator professional , Otis is your best bet but any of them will take a look . You do not want to play around with an elevator yourself . I understand you may have some knowledge of circuitry etc.. But every single person on here will give you the same advice . Please leave it to the guys who do this for a living . If you let people know where you are in sure someone on here will know a good company you can use .
