How Do You Fix a Garage Door That Keeps Going Up and Down?

If your garage door opens, closes, then immediately reopens—or continues cycling up and down—it's not just confusing; it can be dangerous. This behavior is often the result of electrical or sensor issues and needs to be addressed promptly.

1. Sensor Misalignment or Obstruction

If the sensors think something is in the way, the door may reopen as a safety measure. Check that both sensors are aligned and the lens is clean and free from dust, dirt, or cobwebs.

2. Limit and Force Settings

The opener's settings tell it how far to travel. If the down limit is set too far, the door may hit the ground too hard and bounce back open. Adjusting the limit and force settings can usually correct this behavior.

3. Faulty Wiring or Controls

Loose or damaged wires to the opener or wall button can send erratic signals, causing the door to operate unexpectedly. A professional inspection is usually needed to trace the exact fault.

4. Control System Issues

In some cases, the opener's control system may malfunction and send inconsistent commands. This typically requires professional repair.

Conclusion

A garage door that keeps opening and closing on its own should be addressed quickly. While some causes can be fixed with a bit of DIY effort, persistent or electrical issues require a technician's expertise. Call us today for a free site assessment and safe, reliable repair solutions.
