Garage door openers are a great convenience, but come with significant responsibilities too.
Children have been trapped and killed under automatic garage doors, or suffered serious injuries when the closing door failed to stop & reverse its direction. Garage door openers that don’t automatically reverse should be repaired or replaced with new reversing units to prevent this. Older openers may only stop when the door strikes an object. Others may be designed to reverse if it strikes an object, but don’t. Generally these openers cannot be adjusted or repaired to provide the automatic reversing feature found on newer devices, such as an electric eye. Once a garage door is operating properly (when disconnected from the opener), the opener should be checked to ensure it’s force & limit settings are adjusted according to manufacturer’s instructions. If the door does not reverse properly it should be disengaged and adjusted according to the manufacturers specifications, repaired or replaced with a new garage door opener.
Garage doors and the operation of its automatic door opener should be verified regularly to ensure it is functioning as intended. Keep the garage door opener wall switch as high as practical above the floor in an effort to restrict children’s use of it. Keep all remote control devices for the garage door opener locked in the car / away from children. Parents should also tell their children about the potential hazard. Hire a qualified professional contractor if you are not comfortable with performing these tests, repairs and adjustments.
