Nothing. No light, no click, no hum from the unit on the ceiling.
The chain hangs in a loop under the rail and slaps against it on every cycle. It used to sit snug.
After the power came back you pulled the red cord to get the car out. Since reconnecting, the door stops short of the floor, and no amount of turning the limit adjustment brings it the rest of the way down.
Press the button and the motor hums, but the door stays exactly where it is. Under the housing there is a dusting of white plastic shavings, the sign of a stripped drive gear, and this is the second time it has happened.
After a cold night the door stays open until the garage warms up. There is frost on the sensor lenses and a ridge of salty slush piled against the brackets where the snow blower was parked.
The opener is an older one with a row of tiny switches inside the remote. The last remote finally died, the maker stopped selling that model years ago, and the door itself still runs perfectly from the wall button.
A smart hub arrived in the mail with a coin-cell sensor and two wires. The instructions ask what colour your learn button is and how old the opener is.
It is the coldest morning of the year. A week of slush and road salt has crusted over the outside release lock, the key will not seat, and the opener inside is silent after the overnight outage.
