<br>When a door won’t lift, a technician releases tension safely, replaces matched springs and cables, inspects drums and bearings, [roof ventilation and insulation](http://gitea.coderpath.com/aguedasaddler7) resets balance so the door holds mid-travel. Tracks are leveled and rollers lubricated for smooth, quiet motion.
