Garage Door Safety in El Segundo: What Every Homeowner Must Know
2026-05-26 7 min read
In our years serving El Segundo, we've seen this problem again and again: homeowners assume their garage door is safe because it opens and closes. That's not how it works. A functioning door and a safe door are two different things. Missing or broken safety features can cause serious injuries, especially around children. This post walks you through the critical safety components you need to verify right now.
The Photo Eye: Your First Line of Defense
The photo eye, or motion sensor, is one of the two mandatory safety devices on every garage door opener. This infrared sensor sits about 6 inches above the ground on both sides of the door frame. When something blocks the beam while the door is closing, the door stops and reverses.
Here's the catch: a lot of homeowners don't realize the photo eye can get misaligned. Dust, cobwebs, or accidental bumps from a bike or trash can shift the sensors just enough that they stop communicating. The door may still operate, but the safety feature is offline. If a child runs under a closing door and the photo eye isn't working, there's nothing to stop the 400-pound panel from descending.
Check your photo eyes today. Look for dirt on the lens and make sure nothing is blocking the beam between the sensors. If either eye looks damaged or won't light up when you press the opener button, call us for a same-day inspection and repair.
Auto-Reverse: The Second Critical Safety Layer
Every garage door opener manufactured after 1993 must have an auto-reverse mechanism. This system uses either a pressure sensor or the motor's force to detect resistance. If the door hits an object while closing, it should stop and reverse upward within 2 seconds.
Test your auto-reverse monthly. Place a 2x4 block of wood on the ground in the door's path. Close the door from the wall button (never the remote). The door should touch the block and immediately reverse. If it doesn't, or if it hesitates more than 2 seconds, the auto-reverse is not functioning properly. This is not a cosmetic issue. This is a safety failure.
Many homeowners in Long Beach and surrounding areas skip this test because it seems tedious. Don't. Children and pets move fast, and a malfunctioning auto-reverse has led to tragic accidents.
Manual Release Handle and Child Safety
Your opener has a manual release cord hanging from the trolley. In a power outage or opener failure, this lets you open or close the door by hand. Make sure the cord is accessible and clearly visible. Keep it away from children's reach during normal operation, but ensure adults can find it quickly in an emergency.
We also recommend educating children about garage door hazards. A door that weighs 300 to 500 pounds deserves respect. Kids should never play under a moving door or use the opener as a toy. If you have young children, consider upgrading to a smart garage door opener with app controls and real-time alerts.

Springs, Cables, and Structural Integrity
Garage door springs are under extreme tension. A broken spring won't stop the door from closing, but it puts enormous stress on the opener and can cause the door to fall suddenly. Springs last 7 to 9 years under normal use, depending on how often you open and close the door.
If you hear a loud bang from the garage, or if the door feels heavier than usual on one side, a spring has likely snapped. Never attempt to replace a spring yourself. The tension can cause serious injury. Contact a professional to inspect and replace the springs safely.
Similarly, check the cables and pulleys for fraying or rust. Coastal salt air in El Segundo accelerates corrosion, so inspect hardware twice yearly. If a cable snaps, the door can drop fast and cause injury or property damage.

Frequently Asked Questions
How often should I test my garage door safety features? Test the photo eye and auto-reverse at least once a month. Visually inspect springs, cables, and pulleys every three months. More frequent testing is wise if you have young children or use the door daily.
Can I replace a broken garage door spring myself? No. Springs are under 200+ pounds of tension and can cause serious injury or death if they snap during removal. Always hire a licensed professional for spring replacement and repair.
What does a photo eye do if it's blocked by dirt? A dirty photo eye stops communicating with its partner sensor, disabling the auto-reverse safety feature. The door will still operate, but won't stop if a child or pet runs underneath it.
How much does a garage door safety inspection cost? We offer free estimates on all safety inspections and repairs. Call 424-476-4560 to schedule yours today, no obligation.
Are smart garage door openers safer than standard ones? Smart openers add convenience and real-time alerts, but they don't replace the mandatory photo eye and auto-reverse. Learn more in our post on smart garage door openers and what you really need to know.
