LiftMaster Photo Eyes (Safety Sensors)
LiftMaster garage door openers use photo eye safety sensors to detect obstructions and prevent the door from closing on people, pets, or objects. If your garage door won’t close and the opener light flashes, it usually means the photo eyes are misaligned or need replacement.
LiftMaster Photo Eyes FAQs
How do I know if my LiftMaster photo eyes are faulty?
If one or both sensor lights won’t turn on, or if your garage door only closes when you hold down the wall button, your photo eyes are likely misaligned or defective.
Are LiftMaster photo eyes universal?
No. Photo eyes are model-specific. Always check your opener’s model number or learn button color to ensure compatibility.
How do I install new LiftMaster photo eyes?
Mount the sensors on each side of the door near the floor, run the wires back to the opener, and connect them to the terminals marked “Sensor” or “Safety.” Align until both lights are steady.
Can I bypass my LiftMaster photo eyes?
No. Federal safety regulations require all openers manufactured after 1993 to use photo eyes. If your sensors are damaged, they must be replaced to keep your opener functional and safe.
