I live in Oregon and have a Sears Craftsman garage door opener, model # 139.53615SR. It does not use safety photo cells. The problem is that I recently replaced the worm gear that was worn out. I put the unit back together again "pefectly." Now when I push the button or use the remote, all the motor does is run for one second one direction, stop, and then runs in reverse for only one more second. It does this crazy cycle with or without the chain attached, and I have tried every adjustment possible and that is all it does, i.e. one second one way, stops, and one second in reverse. What is possibly the problem? I have double/tripple checked every connection, and the problem persists.
Door opens by it self in the middle of the night
Craftsman 1/3 garage door opener,opens 3 inches then closes. we replaced the sensors and wall switch. the problem persists.
Door will not open without help, start up stop. some times it will openon the 2nd or 3rd try .but if you lift a little it will go up. does not stop at same place every time. some times it will go up on the first try

As I mentioned, the problem has nothing to do with the unit attached to the chain. With or without the chain, the unit runs one second one direction, stops, and then the motor reverses itself and runs for only one second. When you push the button on the remote or the wall switch, it does the same blame thing over and over again. It did this with every chain adjustment possible (and no matter what I did with the limit switches or pressure switch), and when the chain was removed, it acted identically the same way, one second forward, stop, one second back.
What is the Saftey on the chain? Please clarify.
As I have said many times, the unit runs one second forward, stops, and runs one second in reverse. It does this with or without the chain attached. With the chain attached I have done every adjustment imaginable, and it still does one second forward, stops, and reverses for one second. My guess is that something is not connected properly with the wiring (everything was put together immaculately as far as I can tell), or there is some quirky thing going on with the mother board. What saist thou?
well most door opners have a rope or chain that you can pull to open the door with out the motor... just wanted to make sure you have it in the right spot.. sometimes if you set it in the wrong spot .the opener will only run for a few seconds? not sure if you have 1 on ur chain or not?
you took everything apart even the chain? sound like the saftey ..isnt set right on the chain?
