Garage Door Closes Then Opens Liftmaster

Now press the remote control.

Garage door closes then opens liftmaster.

If the garage door does not close completely or begins to close and then opens back up again the down limit switch needs. This will cause the trolley to move into position and reconnect to the garage door. Never permit anyone to cross path of moving door. The opener s force setting may not be set correctly.

Here s a rundown of some of the possible reasons this can be happening. The force setting tells the opener how much resistance the door should provide and if the opener detects more than is allowed the door will reverse. Liftmaster uses the protector system which projects an invisible light beam across the door opening and automatically opens the door if something someone crosses it s path. Make sure the small light on each sensor is lit and not flickering.

Tweak them a bit. I hit the control agian and sometimes it will go back down and raise agian and read more. As is the case with so many issues at the home there s no one reason why your garage door closes then opens. Anytime the main light flashes 10 times and the door reverses to the open position it is a door sensor problem.

Your travel down setting needs to be adjusted. Close the garage door with the opener and watch it closely as it closes. Always keep garage door in sight until completely closed. The simple stuff if the garage door connected to your liftmaster opener only opens part of the way or it begins to open but then reverses check the track and the surrounding area for any objects.

These steps should fix most doors. Your garage door is programmed to travel a certain distance before it closes. Years ago garage door openers were required to utilize safety sensors to prevent doors from closing on small children.
