Signs Your Garage Door Sensor is Out of Alignment

One of the safety features of an automatic garage door is the sensors. They can detect an object on a garage door’s closing way and reverse the closing door to its opening position.

They can only do this when they are in excellent working condition; if damaged or misaligned, safety sensors can cause a severe hazard.

It is thus vital to always make sure your safety sensors are working.

How to test for a working garage door sensor?

It’s essential to test the functionality of a garage door to avoid any accidents. The test is straightforward;

Take any object, say cardboard, and place it in the line of the sensors, then try to close the door.

If the door reverses, it means the sensors are working, and if the door closes without detecting the cardboard, then there’s a problem. You’ll need to troubleshoot to determine the problem with the sensors.

Here are some signs to look for:

1. Check the light indicators- the LED lights on the exterior sides of the garage door will often have a steady green light for working garage door sensors. A bright red light or no light at all shows there’s a misalignment.
2. Check for dirt – if the sensors are correctly lit but not functioning as they should, there must be dirt or debris on the sensors[M1] lenses. Cleaning the lenses can help the sensors work again.
3. Measure the sensors’ unit height to determine if they are aligned – both sensors are supposed to be at equal heights in the opposite direction, literally facing each other.
   If your measurement doesn’t show they are aligned, there may be a problem with the installation, or some wiring connections are damaged. At this point, the best action to take is to call the professionals for a fix.
