Garage Door Safety in Chichester: What Homeowners Must Verify Today
2026-07-08 7 min read
Your garage door weighs as much as a small car. It moves fast. If the safety systems fail, someone gets hurt. Here's what actually matters for garage door safety in Chichester, and how to know if your door is protecting your family the way it should.
The Two Non-Negotiable Safety Features
Every garage door installed after 1993 must have two critical safety devices. Both are required by federal law. Both save lives. Yet most homeowners never check them. See our guide on garage door maintenance in chichester: a homeowner.
The first is the auto-reverse mechanism. When your door encounters an obstacle during closing, the motor should reverse within two seconds. If your door keeps crushing objects or people, the auto-reverse has failed. This isn't a minor inconvenience. This is a legal and safety liability.
The second is the photo eye (also called the photocell). These infrared sensors sit on each side of your garage opening, about six inches from the ground. They create an invisible beam. If something breaks that beam while the door is closing, the door reverses immediately. Photo eyes stop most accidents involving children, pets, and vehicles. Read about garage door safety features in chichester, nh: what actually works.
Both features must work together. A functioning auto-reverse without working photo eyes is incomplete protection. A photo eye that doesn't trigger the motor is useless.
Testing Your Safety Systems at Home
Don't assume these features work. Test them yourself right now. You need less than five minutes.
For auto-reverse: Close your door normally. Before it hits the ground, place a piece of wood (a 2x4 works well) in the closing path. The door should touch the wood and immediately reverse upward. If it hesitates or keeps pushing down, call a technician. This is a repair you cannot delay.
For photo eyes: Close your door. While it's descending, wave your hand through the beam path (about six inches up from the ground, across the entire opening width). The door should stop and reverse. Do this from both sides. If the door ignores your hand, the photo eyes may be misaligned or the receiving unit may be failing.
These tests take the guesswork out of safety. They cost you nothing except a few minutes.
Why Older Doors Need Professional Inspection
If your garage door opener is more than 10 years old, the safety sensors might not be functioning to current standards. Older photo eyes often drift out of alignment. Older auto-reverse motors lose sensitivity over time. This isn't visible wear. It's creeping failure.
We recommend a professional safety inspection every other year for doors older than a decade. For newer installations, an annual check during maintenance season is sufficient. Garage Door Chichester technicians test both systems under load and verify alignment with precision equipment you don't have at home.

Child Safety and Garage Door Habits
Photo eyes and auto-reverse prevent most accidents, but they don't prevent all of them. The photo eye beam sits six inches high. A child crawling under the descending door might slip below the beam.
This is why child safety also depends on homeowner behavior. Never allow children to play in the garage while the door operates. Never let them use the remote as a toy. Teach older children that the garage door is not a game. These habits protect better than any single device.

Common Safety Mistakes in Chichester and Beyond
We service homes across Chichester and the surrounding New Hampshire region. The most common safety mistake we see is adjusting the door's closing force without professional guidance. Homeowners tighten the force to make the door close faster, thinking it's more efficient. They've actually disabled the auto-reverse.
The closing force should be set so the door gently touches the ground and stops, not crashes. If your door slams, that's a force adjustment problem, not a strength issue. The door is doing exactly what the settings tell it to do.
Another mistake is ignoring rust on the photo eye lenses. Salt and moisture corrode the plastic covers. A corroded lens can't transmit or receive the infrared beam cleanly. Wipe your photo eyes monthly with a soft, dry cloth. If you live near the coast or in areas with road salt, clean them weekly.
Your Next Step
Read our detailed guide on garage door safety features that actually work for a deeper dive into maintenance and troubleshooting.
Your family's safety depends on systems that work every single day without fail. If you haven't tested your auto-reverse and photo eyes recently, do it today. If either test fails, contact us for same-day service or call (978) 956-8524. We can typically diagnose and repair most safety issues the same day.
Don't wait until an accident forces the conversation. Garage doors are too powerful and too common to leave to chance.
Frequently Asked Questions
What should I do if my photo eyes are misaligned? First, check that both sensor lenses are clean and free of dirt. If they're clean but still not working, the brackets may have shifted. Loosen the bracket bolts slightly, realign the receiving unit so both lights are bright, then retighten. If you're unsure, call a professional rather than guessing.
How often should I replace the photo eye sensors? Photo eyes typically last 10 to 15 years before the infrared emitters lose strength. If you're testing your door regularly, you'll notice the beam becoming unreliable before complete failure. Replacement cost is usually under $200 and takes under an hour.
Can I disable the auto-reverse to make my door close faster? No. Disabling auto-reverse is illegal and extremely dangerous. The auto-reverse exists because children and pets have been killed by closing garage doors. There is no safety benefit to a faster close that outweighs this protection.
What's the difference between auto-reverse and photo eyes? Auto-reverse detects resistance as the door closes and reverses the motor. Photo eyes detect objects before they're hit and stop the door. Both are required. Both serve different failure scenarios.
How much does a garage door safety inspection cost? A basic safety check runs between $75 and $125. If repairs are needed, we'll provide a separate estimate before proceeding. Many safety repairs cost less than $300 when caught early.
