If when you try to close the door the main light flashes 10 times and the door reverses to the open position 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 flickering. Tweak them a little. If you cannot get both lights to come on you have a bad sensor.

SOURCE: Remote Control closes garage door but does not open

It sounds like a case of your keypad losing signal strength enough that it cannot transmit through the closed door. If a new battery doesn't do the job a new keypad will.

You may just have a weak battery in the keypad or the keypad is going bad and losing range. This is an indication of a weak signal.

SOURCE: garage door only closes halfway

If the main light is flashing 10 times when the door reverses when closing it is a door sensor problem. You can override this with the door control but not with a remote. Make sure the door sensors are pointed at one another and the small light on each one is on and not flickering.

It could be the garage door motor that is acting up. Try closing it with the button in the garage. If that's not the case, you may need a different garage door opener.
