How Does The Safety Reverse Work On A Garage Door

The sensors are located low on each side of the garage door and the 2 beams meet performing a connection.

How does the safety reverse work on a garage door.

The second line of defense is a set of infrared sensors which should be mounted 4 to 6 above the floor on each side of the garage door frame. To increase the amount of force turn it clockwise. Garage doors may display a variety of symptoms if sensors need attention. When the device detects any person or object in the path of a closing garage door it signals the motor to stop the downward action and switch the motion into reverse to stop the obstacle being crushed.

If the door does not reverse it needs attention immediately. The beams are easy to test simply pass your foot in between the two sensors while the door is closing and if the door goes back up you know that they are working properly. When the door contacts the wood it should automatically reverse and return to the open position. Re test the auto reverse function and repeat this process until your opener is properly adjusted.

To decrease the amount of force required to reverse the direction of the garage door turn the knob or screw with a screwdriver counterclockwise one quarter. This safety reverse feature is hidden inside the motor unit and works separately from the safety beam that goes across the bottom of the door.
