Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

Door won't close, with out hold down on button.

Starts to close, then comes back up. Green light on control, and light on
motor flash. If you hold down button on wall control, or either remote it will close all the way. The door returns to open without a problem. I have checked for any think breaking the safety light, and found nothing.

If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure they are pointed at one another and the small light on each one is lit and not blinking.

You need to hook those wires back up and then check the door sensors very closely. If the light in one of the door sensors is dim or flashing it will cause your problem.

If the main light is flashing 10 times when you try to close the door it is a door sensor problem. Make sure the small light on each one is lit, not flickering and that one is not dimmer than the other. Tweak them a bit if necessary.

Both lights on our garage door sensors are green (not blinking), but the door will not close with the remote or button in the garage. It does close if you force it by holding down the button in the garage....


If the main light flashes 10 times when the door starts to close and then reverses it is a door sensor problem. Look very closely at the lights on the sensors. If one of them is flickering ever so slightly it will give you the problem you have.

If the main light is not flashing then you need to increase the down force which is near where all those white wires go. A 1/4 turn should do it.

Liftmaster 1/2 - Will not close


What usually happens is a sensor gets bumped so that they no longer are pointed at one another. They must be for the light on the second sensor to come on. Tweak them and see if you can get the light to come on. If you can't you either have bad wiring going to that sensor or the sensor itself has quit working.
