You press the remote from the driveway and hear the motor hum overhead, a steady drone with no movement behind it. The door stays shut.
The door opens about a third of the way and stops. Turning the limit screw on the head has made no difference, and the trolley seems to sit in the wrong place along the rail when the door is fully closed.
The belt looks fine from a distance, but up close the rubber has cracked across the back in dozens of places and, in one spot, you can see the steel cords showing through.
During the ice storm the power was off for two days. You came home in the dark, found the door dead, and had to climb out of the car to pull the red cord in the cold.
Since shelving went up along the garage wall, the door will not close and both sensor lights are dead. A screw or staple may have gone through the thin wire that runs from the opener to the sensors.
The new car has three buttons in the mirror for garage doors. You held the old remote up to it as the manual said, the light in the car changed, and yet the door ignores it completely.
You are twenty minutes down the highway when the thought lands: did the garage door close behind you? You cannot picture it.
A previous owner knotted the release cord around the rail and stacked storage shelves right beneath it. You only discovered this in the dark, with the power off, a flashlight in your teeth and a car that needed to be somewhere.
