In our years serving Malibu, we've seen this problem again and again: homeowners don't realize their garage door is a safety hazard until someone gets hurt. A garage door weighs 300 to 500 pounds and moves at 6 to 12 inches per second. That's enough force to cause serious injury. The good news? Modern safety features exist specifically to prevent accidents, and most doors built in the last 20 years have them.
Auto-reverse is the non-negotiable safety feature every garage door needs. If the door detects an obstacle while closing, it should reverse direction immediately. Federal law has required this since 1993, but it only works if your sensors are clean and properly aligned.
Here's what happens in the real world: dust accumulates on the photo eye sensors. A child's toy blocks the beam. Someone parks too close. Without a functioning auto-reverse system, the door keeps closing. With it, the door stops and goes back up. The difference between these two scenarios is everything.
We test auto-reverse on every service call. Some homeowners are shocked to learn their system hasn't worked in months because they never tested it themselves.
Photo eyes are infrared sensors mounted on each side of the garage door opening, about 6 inches up from the ground. One sends a beam across to the other. If anything breaks that beam while the door is closing, the auto-reverse kicks in.
The problem we see constantly in Malibu and surrounding coastal areas: salt air corrodes the sensor lenses. Debris blocks them. Someone bumps one out of alignment. When that happens, the safety system fails silently. Your door still operates, but the protection vanishes.
Check your photo eyes right now. Look for dirt, corrosion, or anything blocking the lens. If you see condensation inside the lens cover, moisture has gotten in. That's a sign the sensor needs replacement. This isn't expensive, but it's critical. We can schedule a free quote for garage door safety service and check both sensors during the visit.
Garage doors kill or injure children more often than people realize. Kids get their fingers caught in the panels. They stand under a closing door. They climb up inside the mechanism. Many of these accidents are preventable.
First, teach children that the garage door is not a toy. It's not a climbing structure. It's not something to stand under or reach toward. Second, keep the remote out of reach. A child with a remote is a child who can operate a heavy door without adult supervision.
Third, consider a safety release cord. This manual override lets someone stop the door from inside if needed. If you have young children, learn more about our full garage door maintenance program in Malibu to ensure every safety feature is working.

A broken or fraying spring is a safety hazard most homeowners don't think about. Springs under extreme tension can snap with enough force to cause injury. Cables can snap too. If either fails while someone is near the door, the consequences can be severe.
Springs typically last 7 to 9 years with normal use. Coastal salt air in Malibu accelerates corrosion, so lifespan can be shorter. We recommend annual inspection to catch problems before they become dangerous. For details on spring failure warning signs, read our complete guide to garage door springs.
You should test auto-reverse monthly. Place a block of wood on the ground under the door. Close the door using your remote or button. When the bottom of the door hits the block, the door should reverse immediately. If it doesn't, call us right away.
Test your photo eyes by walking through the beam while the door closes. The door should reverse. Repeat this test from both sides. If the door doesn't reverse on one side, that sensor needs attention.
These tests take 30 seconds and could save a life. Do them now, then do them again next month.

What should I do if my garage door auto-reverse isn't working? Stop using the door immediately and call a professional. A non-functioning auto-reverse is a serious safety hazard. Do not attempt to adjust the sensors yourself without proper tools and knowledge.
How often should photo eye sensors be cleaned? Clean them monthly if you're near the coast, quarterly in other areas. Use a soft cloth and mild cleaner. If cleaning doesn't restore function, the sensors likely need replacement.
Can I adjust my garage door safety features myself? Photo eye alignment requires precision. Springs are under extreme tension and dangerous to handle. Always hire a licensed technician. DIY adjustments often make problems worse.
What's the cost to replace broken photo eye sensors? Typically $150 to $300 per sensor including labor, depending on your door type. Get an estimate before work begins so there are no surprises.
Are older garage doors safe if they have auto-reverse? Auto-reverse helps, but older doors may have other safety concerns. Springs wear out, cables fray, and hardware corrodes. Annual professional inspection catches these issues before they cause injury.
