Too less force when going down: at some point (usually when the door makes the big turn), the power is not enough, the door will retract back, the light will flash and there's warning sound. In such a case, increase a little more down force(say, 1/8 of a turn), until it can go down. Don't turn too much, otherwise the door won't automaticly retract if it hit something(like a pet or a child) when goes down (says the manual, but it's may not be easy to adjust the force to a level so that the door can properly close, and retract if hit sth; if this is the case, adjust so that the door will close properly; even if it won't retract when hit sth, doesn't matter: if a child or a pet is there, the sensor will detect them, and the door will retract anyway).
Over the time, if temp. changes, the controls may change a little(don't know why, and it's a trouble), so the door won't open/close, or doesn't go far enough when open/close, this is the time to adjust again.
No maunal is required, just get a screw driver and try, until the door open/close properly. Of course, if you have and would like to spend money for such a "problem", call somebody to "fix" it.
As I said, nothing wrong with the sensors.更多精彩文章及讨论，请光临枫下论坛 rolia.net
