Outdoor plastic box. Timer runs and turns ON the pump, but will not accept OFF dogs. No matter how hard I tighten them, it crunches them off, grinds them and bends them to its will. I'm in the market for replacing all the guts to get the thing working as it should. I have no idea which model I have? No markings or labels that look like a model number, so can I please get some help? I took a photo of the whole box and the timer motor.
