The Door Won't Open or Close
A door that won't move can stem from a broken spring, a snapped cable, a disconnected trolley, or a power issue at the opener. A door that reverses before closing is usually a safety-sensor misalignment or an obstruction in the tracks. Identifying which system is involved points to the right fix.
Noisy or Rough Operation
Grinding, squeaking, and rattling usually come from worn rollers, dry hinges, loose hardware, or bent tracks. These are early warnings that maintenance is overdue. Addressing them promptly keeps a minor annoyance from becoming a roller that seizes or a door that jumps its track.
Uneven or Sagging Movement
When a door hangs crooked, closes unevenly, or feels heavy, the cause is often an out-of-balance spring or a cable that has slipped or frayed. Because these parts are under high tension, this is a repair to hand off to a professional rather than tackle yourself.
