A: Remove your magnet from the gate and hold it in your hand.  Remove the blue cover from your control box.  Face the control box so that the battery cover is facing toward you.  Press the button on your remote control to activate the gate.  With the magnet in your Right hand, slowly run the magnet up the Right side of your control box just until it causes the motor to stop.  Hold the magnet there and press the button on the remote control again to activate the motor.  Run the magnet up a little more until it stops the motor.  If the magnet fails to stop the motor in either of those positions, then the magnetic switch is malfunctioning.  If it works, then the magnet needs to be adjusted when reinstalled onto your gate.  I hope this makes sense.  Please let me know the outcome so that we can take this further if necessary.
