Aligning the Safety Reversing Sensors

The door will not close if the sensors have not been installed
and aligned correctly.
When the light beam is obstructed or misaligned while the door is
closing, the door will reverse and the garage door opener lights
will flash ten times. If the door is already open, it will not close.
1. Check to make sure the LEDs in both sensors are glowing
steadily. The LEDs in both sensors will glow steadily if they
are aligned and wired correctly.
The sensors can be aligned by loosening the wing nuts, aligning
the sensors, and tightening the wing nuts.
IF THE AMBER LED ON THE SENDING SENSOR IS NOT
GLOWING:
1. Make sure there is power to the garage door opener.
2. Make sure the sensor wire is not shorted/broken.
3. Make sure the sensor has been wired correctly: white wires to
white terminal and white/black wires to grey terminal.
IF THE GREEN LED ON THE RECEIVING SENSOR IS NOT
GLOWING:
1. Make sure the sensor wire is not shorted/broken.
