What actually breaks on London garage doors
A torsion spring, a cable off its drum, rollers out of the track, the photo-eye sensors at the bottom of the tracks, and the opener. A spring goes with a bang and the door will not lift. A cable slips and one side hangs lower than the other.
A sensor knocked out of line makes the door reverse instead of closing, usually with the opener light blinking a count at you. When the motor runs and the door stays put, the gear kit has stripped.
The freeze-thaw cycles and cold snaps detailed in The winter this branch works in accelerate wear on springs, cables and rollers, making these the most frequent repairs our London technicians handle.
The mechanics of each of those live on the service pages linked below. What this page is for is the branch: where it goes, what the season does, and how to reach it.
