Most people don't think about their garage door until it stops working. By then, the safety systems that should protect your family have already failed. In New London and across Connecticut, we've responded to injuries that were entirely preventable. This post covers the safety features every garage door needs, how they fail, and what to do about it.
Your garage door has two independent safety mechanisms required by federal law. Both must work for your door to be safe around children, pets, and vehicles. See our guide on smart garage door technology in new london: what you need to know.
The auto-reverse system stops and reverses the door if it encounters resistance while closing. A cable snaps, a toy blocks the path, a hand gets caught. The door feels the obstruction and goes back up. If this fails, a 400-pound door can crush whatever is underneath.
The photo eye (or photoelectric sensor) is the second line of defense. Two small sensors sit about 6 inches off the ground on each side of the garage opening. They create an invisible beam. If anything breaks that beam while the door closes, it triggers the auto-reverse. Kids, pets, bikes, boxes. The photo eye catches them all. Read about how a new garage door can boost your home.
Both systems must function. One alone is not enough. Many garage doors in New London have one or both disabled, either accidentally through misalignment or deliberately by someone who thought the sensors were inconvenient. That's a disaster waiting to happen.
Photo eyes are simple but vulnerable. Dust, spider webs, garage grime, and even condensation can block the infrared beam. I've seen families with photo eyes that haven't worked for months because the lens was dirty.
Test yours right now. Open your garage door. While it's opening, wave your hand in front of the photo eye sensor at floor level. The door should reverse immediately. If it doesn't, close the door manually and clean both lenses with a soft cloth. Try again.
If it still doesn't reverse, the sensor is misaligned or broken. This is a safety failure. Don't ignore it. A misaligned photo eye won't protect your child. Get it fixed before the next time you use the door.

The auto-reverse system depends on properly functioning springs. When springs wear out, the door becomes heavier and harder for the opener to lift. The opener struggles. The auto-reverse sensitivity gets thrown off. A child's finger under a descending door might not trigger the reversal because the door is working too hard.
Springs last 7 to 9 years in Connecticut's climate, not 10 or more. Salt air near the coast accelerates rust and failure. If your springs are older, have them inspected. A broken spring is also a child safety issue because the opener can't lift the door smoothly, and the auto-reverse can't react properly.
We wrote a detailed guide on garage door spring replacement costs in New London that covers the warning signs. Read it if you've noticed your door opening slower or harder than usual.
Photo eyes and auto-reverse are mandatory, but child safety goes deeper. Teach children never to play under a moving door. Don't let them use the remote as a toy. Keep remote controls away from toddlers. A three-year-old accidentally pressing the button can trap a sibling underneath.
Modern smart garage door openers add another layer. You can receive alerts on your phone when the door opens or closes. You can close it remotely if you left it open. Learn more about smart garage door technology in New London to see if this fits your family's needs.
Check your photo eyes this week. Clean the lenses. Test the auto-reverse. Look for rust or damage to springs. If anything feels wrong or the door isn't responding normally, don't use it until it's inspected.

What does the photo eye do on a garage door? The photo eye is a sensor that detects objects or people in the door's path. If the beam is broken while the door closes, it triggers the auto-reverse, stopping and reversing the door upward to prevent injury or damage.
How often should I test my garage door's auto-reverse? Test it monthly by waving your hand in front of the photo eye while the door closes. The door should reverse immediately upon obstruction. If it doesn't, have the system inspected by a professional right away.
Can I disable my garage door's safety sensors? No. Federal law requires photo eyes and auto-reverse on all residential garage doors manufactured after 1993. Disabling them is illegal and extremely dangerous, especially around children.
What causes photo eyes to stop working? Dirt, dust, spider webs, condensation, and physical misalignment are common causes. Sometimes the sensor itself fails. Clean the lenses first, then test. If it still fails, the sensor may need replacement.
Are garage door springs a safety issue? Yes. Worn springs make the door heavier and harder to lift, which interferes with the auto-reverse's ability to detect resistance and react quickly. Have springs inspected every 5 to 7 years in Connecticut.
