Door will not stay closed

Press button to close door, door closes. then it reopens. i suspect it has to do with elctric eye safety device, which i would just as soon disable if that will make the darn thing close.

Upon pressing open/close button kitchen door the garage starts to close but then reopens after 3-4". one must then hold button until door is fully closed. what is remedy?


The problem is that your system does NOT "see" the safety "eyes" sensors. Make sure that your sensors are properly connected to the opener (both sensors should have lights on them, one amber and another green). If they do not, check the wiring and the connections at the opener itself.

Door starts to open/close only travels 8" then reverses/stops


The problem is most likely with the safety "eyes" sensors. Your system does not see them. Rather than opening even without sensing the safety "eyes" sensors like most older system do, this model apparently has a safety feature built in, that without proper communication between the safety "eyes" sensors and the main console, the door will not operate at all. Some people had reported that in a situations like yours, if they the button on the remote pressed, the door will open/close, though this is not recommended.

My Craftsman garage door opener opens fine. It


It could be closing too far or the sensitivity could be set too sensitive.

Lube the springs, wd-40 rust may be the whole problem.

If the door hits and the opener continues to move until the rail flexes upward and then reverses - probably the travel adjustment.

Does the door close and stay closed if you hold the wall button down constant until it closes? - this would indicate a safety eye problem.

If the door reverses before it hits the floor or just as it hits the floor it could be the sensitivity or if the safety eyes are mounted to the track they could be flexing enough to move the eyes out of alignment.

Hope this helps.

Door opens byitself


You have 2 floor photo eyes that run a beam across so that if a kid runs under the door it will go back up. If the door wont close and goes back up I would check to make sure those lights on the 2 photo eyes are lined up properly. Here is a link also Click Me If you cant get it to stay close there is a emergency cable that you can release to close the door until you can get it figured out. Lost of good info here as well. If this Info was useful please rate me and have a great day.

Pressing remotes the door won't go u[


It sounds like you have the lock enguaged. When it is flashing it locks out all remote access. Hold the lock button for 3 seconds. The green light should go solid. On the issue of closing, it is most likely a safety eye issue. Hold down the wall button. If it closes it is the safety eyes. Holding the button overrides the safety eyes. Make sure that thelight on both eyes are both lit.
