Jim B. for Model Number GX900PLSO Think I forgot to give you model number. Again when hitting start button, unit does not start. If I hold button in it will start and run Down to compact and back up. When it has reached the top it makes knocking noise and I release start button, Yale complete. If bad part is still motor switch please confirm and I will order promptly. Thanks again
