Automated garage doors have sensor systems that prevent them from opening or closing when there are objects or people in their paths. These safety features help keep vehicles and children safe. Here is an overview of how these sensors work.

What Do Garage Door Safety Sensors Do?

A photoelectric sensor is mounted on either side of a garage door, about six inches from the ground. The first casts an infrared beam across the doorway, while the second receives the beam.

If an object or person stands in the beam’s path while the door is in motion, the sensors stop the unit’s movement. The door then moves in reverse to avoid hitting whatever is blocking its way.

How Can Homeowners Maintain These Sensors?

Garage door sensors are legally required for every product manufactured after 1993 because they help protect people, particularly children, from injuries caused by heavy doors. They also safeguard vehicles from damage. Therefore, it’s essential to ensure the ones on your unit function properly.

If a garage door stops mid-movement when no object or person is in its path, the sensors might be dirty, misaligned, or loose. Ensure they’re properly aligned and facing each other, then wipe each lens clean with a soft cloth. Also, tighten any connective hardware, as vibrations caused during operation could shake loosened sensors and break the beam.
