4.) Safety Feature Test (Auto-Reverse)
There are two security mechanisms in your garage: mechanics and photocells. The door that does not have this safety feature is outdated and needs to be replaced soon.
To test the mechanical safety features in your garage, place solids on the ground in the path of the garage door. When the garage touches the object when it closes, it should automatically go back up.
When testing the feature of the photocell in your garage, simply stick your feet on the door as it closes. Your feet will be in contact with the photoelectric (invisible) beam that extends at the bottom of the door. The garage should automatically reverse once your feet touch the photoelectric beam.
