Torsion vs extension, wire size and cycle rating.
01Why doors come off track
Bumping the door with a car, a broken cable, worn rollers or loose track brackets. Sometimes the opener keeps pushing after something blocked the door, forcing it out.
02The repair
The technician releases tension safely, realigns or replaces bent track sections, resets rollers, replaces damaged cables and checks balance and safety reverse.
03Prevention
Keep tracks clear, replace worn rollers early and test the reverse feature monthly. Damaged sections may need garage door panel replacement.
