I had a similar brain lapse a few years ago. We left for a weekend getaway early one Saturday morning and returned very late Sunday night. When I was coming around the curve to the house, I reached for my garage door opener and looked up to see the garage door wide open. I checked the house, and everything was exactly as we left it. I am 100% sure I hit the button to close the garage door when we left as was the wife, but we didn't wait for it to fully close. I can only surmise that for some reason the light beam safety feature must have been activated opening the door back up.
Now I always wait for the door to fully close then an extra 5 or 10 seconds to make sure it is fully closed.
^^^^This!
Sometimes they "bounce" and return to top. If only could get Wifey to wait to see before hitting the gas pedal!
