Door Closes Suddenly With a Bang
A door that opens normally, but closes with a sudden bang is showing signs of a serious problem with a broken torsion spring or cable. When a door is doing this, there is a potential for a serious accident or injury because the emergency reopening mechanism may not be functional and a person or pet could be trapped under the door as it closes.
Garage doors that are out of control at any point as they open or close should be serviced by a garage door specialist as soon as possible.
The best way of avoiding all of these unnerving and potentially dangerous problems with your garage door is by having it regularly serviced by a professional garage door service technician. Then you will never have to worry about your garage door developing a mind of its own.
