What are some reasons a garage door might not open?

The reasons a garage door might not open include broken springs, low batteries in the remote control and worn cables. Broken springs are a common problem for garage doors. Motors cannot lift garage doors on their own if a spring breaks or snaps. Installing new springs fixes this issue.

Weak batteries in the garage door remote control can cause inconsistent operation. The door opens and closes properly after replacing the batteries. Cables run along the side of the door from the bottom. They often break when the springs do. Both need replacement and may require the expertise of a garage repair specialist.
