How to align safety sensors on your garage door?
If your garage door is going down and reversing back up, try this simple solution to get it fixed. The lights on both the sending and receiving sensors will glow steadily when the wiring connections and alignment are correct. The amber light on the sending sensor will glow regardless of alignment or obstruction. (Meaning this light will always be on no matter what) If the green light on the receiving sensor is off, dim, or flickering (and the invisible light beam path is not obstructed), alignment is required. Note: On the older safety sensors both lights are green. The receiving sensors are the sensors that the green light goes out when you pass your hand in front of the sensors. The sending sensor stays solid. Before you take off the photo eye try just adjusting it to make it see the other one by wiggling it into place if that does not work take the following steps.
1. Remove the receiving sensor (green light) from bracket. You can do so by taking off the wing nut.
2. Point the sensor away from the sending sensor, so that the light is completely off.
3. Once the light is off, wait 10 seconds.
4. Slowly rotate sensor back, aligning sensor with sending sensor, until it lights up green again. When you have a strong green light, put it back into the bracket and put the wing nut back on.
Note: If you are unable to get the door closed and the safety sensors are the issue, the garage door can be closed by pressing and holding the push button on the wall until down travel is completed.
