Common Causes Behind Garage Doors Opening Spontaneously

  1. Malfunctioning Garage Door Opener: One of the most frequent causes of a self-opening garage door is a malfunctioning garage door opener. This can result from worn gears, a faulty motor, or a damaged circuit board. A professional inspection and potential replacement of these components may be necessary.
