I have a sears garage opener with a chain and sprocket drive. It is approximately ten years old. Now it closes all the way but then re-opens. I tried to adjust so it did not close so far but adjustment doesn't work. When it opens it opens all the way until it hits the stop nut. The others (3 total) do not do this. It seems it has lost track of how far it is openening. Any ideas would be apreciated!
