If your garage door randomly doesn't close and the light blinks, you may have a failing sensor.

My garage door would usually work, but sometimes it would start closing, only to open back up and the door opener light flashed 10 times. It didn't happen every time, sometimes in winter, sometimes in summer, sometimes hot, sometimes cold. But, it was always on sunny days. After looking at the code (10 flashing lights) in the manual, I still didn't know what the problem was. Finally, I tried replacing the sensor since the sunny weather seemed to be the only consistent thing. It worked and the door now closes every time. My guess is that the sensor had lost some of it's strength, and the sunny day somehow overpowered the sensor strength. That's only a guess, but it worked for me to replace the door.
