Short answer: The photo-eye sensors near the floor keep your door from closing on people, pets, and cars.
The photo-eye sensors near the floor keep your door from closing on people, pets, and cars.
How the Photo-Eyes Work
Two sensors mounted a few inches above the floor send an invisible beam across the opening; if anything breaks the beam while the door is closing, the door reverses.
Fixing Sensor Problems
A blinking opener light often means the sensors are misaligned, dirty, or have a loose wire. Cleaning the lenses and realigning them until both show steady lights usually restores normal operation.
