| After pressing the inside garage door opener button, the garage door goes up only 2 ft, then stops. A next push of the button sends the door successfully back down, closed.
Multiple trys produces the same result: partway up -- all the way down. (Model 41A4315-7C) Nothing is blocking the doorway sensor and all machinery and connections are intact. ANY SUGGESTIONS? |

| First of all take a good close look at the springs at the door. Make sure one of them has not broken. If ok, there is a control at the rear of the motor unit called the 'up force'. Turn it a quarter turn and try. Do not adjust the 'down force'. |
