How Does The Safety Reverse Work On A Garage Door

In addition to this the us consumer product and safety commission also states.

How does the safety reverse work on a garage door.

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. Re test the auto reverse function and repeat this process until your opener is properly adjusted. 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. If you re not comfortable adjusting the settings yourself contact a trained garage door technician.

If any object blocks the path of the infrared sensors the garage door opener will not activate or will reverse if operating. 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. The sensors are located low on each side of the garage door and the 2 beams meet performing a connection.

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. 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.
