Re test the auto reverse function and repeat this process until your opener is properly adjusted.
How does the safety reverse work on a garage door.
If the door does not reverse it needs attention immediately.
When the door contacts the wood it should automatically reverse and return to the open position.
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 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.
If any object blocks the path of the infrared sensors the garage door opener will not activate or will reverse if operating.
If you re not comfortable adjusting the settings yourself contact a trained garage door technician.
The sensors are located low on each side of the garage door and the 2 beams meet performing a connection.
In addition to this the us consumer product and safety commission also states.
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.
