Check your door sensors. They have probably been bumped. Tweak them until they are pointed at one another and the small light on each one is lit and not blinking.

    If the light is out on both sensors you have either a wiring problem or a bad logic board. You can check the wiring to the sensors but I really suspect your logic board.

If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

Garage Door won't close


It sounds like the door sensors have been bumped or somehow gotten misaligned. Tweak them until the light on each one is lit and not blinking. They must be pointed at one another.
