Chamberlain Garage Door Opener Photo Eyes
Chamberlain garage door openers use photo eye safety sensors to prevent the door from closing on people, pets, or objects. If your garage door only closes when you hold the wall button or the opener light flashes repeatedly, the sensors are likely misaligned, blocked, or need replacement.
Chamberlain Photo Eyes FAQs
How do I know if my Chamberlain photo eyes need replacing?
If one or both sensor lights don’t turn on, or the door only closes when the wall button is held down, the sensors are likely misaligned or defective.
Are Chamberlain photo eyes universal?
No. Sensors are model-specific and must match your opener’s technology and manufacture date. Confirm compatibility before ordering.
How do I install new Chamberlain photo eyes?
Mount the sensors on each side of the garage door, 4–6 inches off the floor. Run the wires to the opener’s sensor terminals and align until both indicator lights are steady.
Can I bypass Chamberlain photo eyes?
No. Federal safety standards require functioning photo eyes on all openers manufactured after 1993.
