To increase the amount of force turn it clockwise.
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 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.
If the door does not reverse it needs attention immediately.
Garage doors may display a variety of symptoms if sensors need attention.
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.
When the door contacts the wood it should automatically reverse and return to the open position.
In addition to this the us consumer product and safety commission also states.
The sensors are located low on each side of the garage door and the 2 beams meet performing a connection.
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.
Re test the auto reverse function and repeat this process until your opener is properly adjusted.
