In our years serving Burbank, we've seen this problem again and again: homeowners don't realize their garage door opener lacks basic safety features until something goes wrong. The photo eye and auto-reverse mechanism aren't fancy upgrades. They're critical child safety devices that federal law requires on every residential garage door opener made after 1993. If your door doesn't have them, you need to act now.
A photo eye is a simple sensor pair mounted on each side of your garage door opening, about 6 inches from the ground. When the door closes, it passes through an infrared beam. If anything breaks that beam during closure, the door stops and reverses. The auto-reverse mechanism is the motor's ability to detect excessive force or obstruction and automatically move the door back up.
Together, these systems prevent crushing injuries and deaths. In the 1980s, before these became mandatory, children were seriously hurt or killed when garage doors closed on them. The safety standards changed for good reason.
Burbank's older neighborhoods have many doors installed in the 1970s and 1980s, before safety regulations took hold. Even some doors from the early 1990s came with openers that lack proper photo eye alignment or functioning auto-reverse. If your garage door opener is more than 15 years old, it's likely not meeting current safety standards.
Temperature swings in Burbank can also affect sensor alignment. Heat causes metal frames to shift slightly, which can throw photo eyes out of sync. Dust accumulation from dry months blocks the infrared beam. These aren't just maintenance headaches. A misaligned photo eye is a non-functional photo eye.
I've met homeowners who assumed their older openers were fine because "the door works." Working and safe are not the same thing. A door can operate smoothly while missing the safety redundancy that protects a child standing in the path.
Look at your garage door opener motor. Is there a small sensor mounted on a bracket near the floor on each side of the opening? If not, you don't have photo eyes. Press the door's close button and listen. Does it stop and reverse when you hold your hand in the beam path? If it doesn't, the auto-reverse isn't functioning.
You can also check your owner's manual, though I understand not everyone keeps those. The safest move is to call a professional and ask for a free safety inspection. We can test both features in minutes and give you an honest estimate if upgrades are needed. Schedule a free quote and let us verify what you've got.

Beyond sensors, many doors lack proper balance. An unbalanced door puts extra strain on the auto-reverse mechanism and can fail to reverse when it should. Worn cables or springs also reduce stopping power. If you've noticed your door closing harder or faster than it used to, that's a sign the springs are weakening.
Door tracks that are bent or misaligned also compromise safety. The door can bind or move unevenly, which interferes with the auto-reverse's ability to detect obstruction. Rust and debris in tracks create the same problem. Our maintenance tips guide covers track care in detail.
For households with young children, I always recommend testing photo eyes weekly. Clean the sensor lenses with a soft cloth. Make sure nothing blocks the beam path, such as bikes or stored items. This takes 30 seconds and could save a life.
When you replace an opener or install a new door, professional installation matters. Sensors must be mounted at the correct height and angle. The force and travel settings on the motor need adjustment so the auto-reverse triggers at the right threshold. Too loose and it won't stop for a child's hand. Too tight and it reverses on normal obstructions like leaves.
We also check that the safety cables holding the springs are in place and intact. If a spring breaks, the cable keeps the door from falling. It's a fail-safe that costs almost nothing but saves lives. Read more about spring safety in our post on warning signs your springs need replacement.

I won't sugarcoat this. A hospital visit for a garage door injury costs far more than a same-day safety upgrade. An auto-reverse retrofit is usually under $300. Photo eye replacement runs $100 to $200. Spring replacement or motor adjustment adds to that, but it's still modest compared to an emergency room bill.
If you've been putting off a safety check because of cost concerns, call us. We price honestly and will tell you exactly what needs fixing and why. No padding the estimate. No pressure to replace working parts.
Your family's safety isn't something to delay. If your garage door opener is more than 15 years old, or if you're unsure whether your photo eyes and auto-reverse are working, reach out today.

Q: How often should I test my garage door's safety features? A: Test the auto-reverse and photo eye weekly if you have young children. Press the close button and hold your hand in the beam path. The door should stop and reverse. Clean sensor lenses monthly to prevent false breaks in the infrared beam.
Q: Can I replace just the photo eye without replacing the whole opener? A: Yes. Photo eye sensors can be replaced separately for $100 to $200. However, we'll test your entire opener first. If other components are worn, upgrading the motor may be smarter long-term than patching one part.
Q: What if my garage door opener is pre-1993? A: It lacks federally mandated safety features. We recommend replacing the motor with a modern opener that includes auto-reverse and photo eye capability. A new opener typically costs $400 to $800 installed, and it's worth the investment.
Q: Do manual garage doors need photo eyes? A: Manual doors don't have openers, so they don't have photo eyes or auto-reverse. However, they should still have proper balance and functional safety cables. Always inspect a manual door before using it.
Q: How do I know if my photo eye is misaligned? A: Close the door and watch the sensors on each side. They should emit a steady light. If one flickers or is dark, the beam is broken. Wipe the lenses first. If the light doesn't return, the sensor needs repositioning or replacement.
