A loud bang coming from your garage door can be alarming, especially if it happens suddenly while the door is opening or closing.
In most cases, the noise is a symptom of a mechanical issue that needs attention.
Understanding what causes these sounds can help you address the problem early and avoid costly repairs later.
Broken Torsion Spring
One of the most common causes of a loud bang is a broken torsion spring.
These springs are mounted above the garage door and are responsible for lifting the weight of the door.
When a torsion spring snaps, it releases a lot of tension at once, often creating a sharp, explosive bang. If this happens, the door may become heavy, uneven, or won’t open at all.
A broken spring is dangerous to repair yourself, so it’s important to call a qualified technician.
Loose or Worn Hardware
Another possible cause is loose or worn hardware.
Over time, bolts, hinges, and rollers can loosen from regular movement. When a part shifts out of place, it can create banging or clunking noises during operation.
A regular service check can tighten hardware, lubricate components, and prevent further wear.
Bent or Misaligned Tracks
Sometimes, the tracks themselves are the issue.
Bent or misaligned tracks can cause the door to jerk or slam as it moves along the rails. This not only creates noise but can also strain the motor and other moving parts.
Age and Lack of Maintenance
Lastly, if you have an older garage door, the bang may simply be due to age and lack of maintenance. Springs weaken, rollers deteriorate, and the system becomes louder over time.
If your garage door is making a loud banging noise, it’s best to stop using it until the cause is identified.
A professional garage door technician can diagnose the problem safely and get your door running smoothly again.
Regular maintenance is the key to preventing these issues and extending the life of your garage door system.
