For a few days there was a grinding sound whenever the door started moving. Now the motor spins freely and the door stays exactly where it is.
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.
It is minus twenty in the detached garage and the door climbs in jerks, the belt stiff as a board. By the afternoon, when the sun has been on the door, it runs almost normally again.
The bedroom above the garage shakes every morning at six when the chain drive fires up. Everyone in the house knows the moment someone leaves for work.
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 outdoor keypad worked all summer. Now that the mornings are below freezing it lights up faintly, takes the code, and the door does nothing.
There is a wireless symbol printed on the opener above the car, and the manual mentions an app, but the head unit has never been connected to anything. You downloaded the app once, it asked for a serial number and a network, and the moment passed.
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.
