Instead your pre wire is broken and you need to get it replaced. If the sensors are working the garage door should immediately stop closing and return to the open position.

In this case you will set up the level aligned with one sensor then adjust the opposite sensor until the beam of your laser level is hitting the sensor. If the leds on both sensors glow it means they are not faulty. Start by inspecting the wires that are going into both of the sensors. Connect the white wire from the sensor to the white terminal of the garage door opener and then the black and white wire to the grey terminal.

Proper height for a garage door sensor is 4 to 6 inches 10 2 to 15 2 cm. If the door still won t stay shut double check that the sensors are aligned with each other.
