In our years serving Arlington, we've seen this problem again and again: homeowners don't realize their garage door lacks modern safety features until a close call happens. Auto-reverse and photo eye systems aren't luxury upgrades.they're essential safeguards that prevent crushing injuries and property damage. If your door was installed before 2000, or if you've never had these systems inspected, this post is for you.
Auto-reverse is a mechanical safety feature that stops and reverses a closing garage door when it encounters an obstacle. Think of it as an emergency brake. When your door hits something.a toy, a pet, or worse, a person.the motor immediately stops and pulls the door back up. This happens within a fraction of a second.
Federal law has required auto-reverse on all residential garage door openers since 1993. That said, older systems can wear out or malfunction. Springs lose tension over time (typically lasting 7,9 years), and worn components can slow the reversal response. A sluggish auto-reverse is almost as dangerous as none at all.
We test auto-reverse during every maintenance visit at Garage Door Arlington. The test is simple: we place a wooden block under the closing door. A properly functioning opener detects resistance and reverses immediately. If yours doesn't, that's a red flag requiring urgent attention.
Photo eyes (also called safety sensors) are infrared beams that run across your garage door opening, usually 6 inches from the ground. If anything breaks that beam.a child running through, a car backing up, even a pet.the door stops before it closes.
Photo eyes are equally mandated by federal code and work independently of auto-reverse. Many homeowners don't realize their doors have them because they're small, mounted on either side of the opening, and largely invisible. Dust, spider webs, misalignment, or damage can render them useless without you knowing.
Arlington experiences wet, rainy seasons that can corrode the lens or the wiring. We've found photo eyes that haven't worked in years simply because the homeowner couldn't see the problem. During a same-day service call, we clean, realign, and test them to ensure they function properly.

Garage doors are among the top causes of childhood injuries in residential settings. A door weighing 300,500 pounds descending at full force can cause severe harm in seconds. That's why child safety isn't just a talking point.it's the reason these systems exist.
If you have young children or grandchildren visiting, photo eyes are non-negotiable. We recommend testing them monthly: walk through the beam while the door is closing. It should stop every single time. If it doesn't, call us immediately.
Beyond sensors, we also recommend educating kids never to play under or near a closing door, and teaching them that the garage door opener remote is not a toy. You can read more about comprehensive garage door maintenance in our complete opener troubleshooting guide, which covers safety checks alongside repair steps.
You don't need professional tools to do a basic safety check. Here's what you can do right now:
Auto-reverse test: Place a small wooden block under the door as it closes. It should reverse immediately upon contact.
Photo eye test: Wave your hand across the opening while the door is descending. It should stop before closing.
Visual inspection: Look at both photo eye lenses. They should be clean and unobstructed. Wipe them gently with a soft cloth if dusty.
If either test fails, don't delay. Faulty safety systems compound the risk every time the door operates. Get a free estimate from us.we'll assess your current setup and explain the cost of any repairs or upgrades you need.
Safety repairs are some of the most honest investments you can make in your home. A photo eye replacement typically runs $150,$300, including labor. Auto-reverse servicing or replacement is usually in the $200,$400 range, depending on your opener model. We always provide a transparent estimate before starting work, so you know exactly what you're paying for.
If you live in Arlington or nearby areas like Marysville or Lake Forest Park, we offer same-day appointments for safety concerns. Garage door injuries don't wait, and neither should you.
Don't assume your door is safe just because it closes. Safety systems degrade silently. Call us at (360) 282-0676 or visit our contact page to schedule a safety inspection. We'll test your auto-reverse and photo eyes, identify any issues, and give you an honest estimate. Your family's safety is worth the peace of mind.

How often should photo eyes be tested? We recommend a monthly visual check and functional test. During seasonal maintenance.especially before winter.have them professionally inspected and cleaned to remove dust and debris buildup.
Can I replace a photo eye myself? While physically removing an old sensor is simple, proper alignment is critical. Misaligned sensors won't detect obstructions. We recommend professional installation to ensure safety compliance.
What if my garage door opener is older than 20 years? Older openers may lack modern safety features or have degraded components. We can retrofit safety sensors or recommend a replacement. Either way, don't operate an unsafe door regularly.
Do both auto-reverse and photo eyes need to work? Yes. They're redundant systems for a reason. If one fails, the other provides protection, but operating with only one is riskier than operating with both. Test them together.
How much does a garage door safety inspection cost? We typically roll a safety inspection into routine maintenance visits at no extra charge. For a standalone inspection, call (360) 282-0676 for a quote.
