Blocked or misaligned photocells. All modern door openers are equipped with photocells, which detect if a person or object is in the way of the door as it closes. If the connection between the sensors is disrupted, the door will automatically stop closing to prevent injury or damage to objects or people in the door's path. Blocked or misaligned photocells may be the cause behind a malfunctioning door.
Missing or broken safety cables. When an extension spring breaks, it releases a tremendous amount of energy and, if uncontrolled, can seriously injure a person or damage a vehicle or a wall. However, properly installed safety cables prevent damage and injury by controlling failed extension springs. Unfortunately, many homes in our area were constructed before the installation of safety cables was common. If the garage door has extension springs, but not safety cables, arrange for the installation of safety cables as soon as possible.
Frayed cables. All cables should be periodically inspected and any frayed cables should be promptly replaced. Because garage doors are heavy, waiting for a frayed cable to break before replacing it can be very dangerous. Even if no damage or injury occurs due to the break, there may be an inconvenience if the car is inside the garage and the garage door cannot be opened.
