Modern electric garage doors come with mechanisms that promote safer and more secure homes. Among these are photo eye sensors, which are designed to detect objects in the path of the overhead doors. These sensors will cause the doors to automatically reverse if something is detected below them, preventing damage to property and injury to pets and animals. Consider the following guide on how to maintain the sensors so that the doors function correctly and don’t present a hazard risk.

How to Maintain Photo Eye Sensors

1. Check the Alignment

Your garage door photo eye sensors should sit about two the three inches from the ground and face directly toward one another. When in alignment, the red or green lights beneath the lenses will illuminate. If you need to adjust the alignment, loosen the bolts with a wrench. Move the sensors until their internal lights illuminate before retightening the bolts. 

2. Clean Regularly 

Since overhead door sensors sit so close to the ground, they may easily collect dirt and debris, preventing them from detecting obstructions accurately. Every few months, use a soft and clean cloth to wipe away cobwebs and dust. Use a solution of gentle detergent and water to remove grime and grease from the lenses. 

3. Inspect Circuits 

If your sensors are in alignment, but the power lights do not illuminate, check the circuits in the opener unit. Unplug it, and remove the back cover. If you notice loose wires, tighten the terminal screws to which they attach. If the lights still do not illuminate, ask a garage door maintenance company to replace the sensors.

4. Schedule Professional Services

Approximately once per year, get in touch with a garage door maintenance team to schedule a professional inspection. They’ll make sure your sensors function normally and perform repairs and replacements as necessary. Additionally, they’ll check the wiring, metal track, and doors for signs of damage.
