A2Z Garage Doors
A garage door weighs 300 to 500 pounds. When it closes, it generates enough force to cause serious injury or death if safety mechanisms fail. Your photo eye and auto-reverse system are the only things standing between your family and a tragedy. If either is broken or misaligned, you need a repair today, not tomorrow.
The photo eye is a sensor pair (transmitter and receiver) mounted on each side of your garage door opening, typically 4 to 6 inches above the floor. When an object blocks the invisible infrared beam between them, the door should stop and reverse immediately. This is your first line of defense against crushing injuries to children, pets, or vehicles.
Most photo eye failures happen silently. You might not notice until something goes wrong. Dust, spider webs, condensation, or misalignment can block the beam. If your door closes even when something is in the way, your photo eye is failing. Don't assume it will work next time. The problem usually gets worse, especially during Oregon's wet months when moisture accumulates inside the sensor lens.
I've responded to calls where a child was inches away from being crushed because the photo eye wasn't functioning. The homeowner had no idea it was broken. They thought their door was fine because it opened and closed. That's the danger: photo eyes don't announce their failure. You have to check them.
Auto-reverse is a mechanical and electronic backup system. Even if your photo eye fails, the auto-reverse should sense resistance when the door hits an obstacle and reverse direction within 2 seconds. This is required by federal safety code, but many older systems have weak or worn-out sensors.
Your opener's auto-reverse relies on a force-sensing mechanism. As the door descends, it measures the force needed to move it. If that force suddenly increases (because something is blocking it), the door reverses. Over time, these sensors lose calibration. Springs wear out. The door becomes heavier or lighter, throwing off the sensitivity.
Test your auto-reverse once a month. Place a roll of paper towels under the closing door. If the door hits it and doesn't reverse within 2 seconds, you have a safety problem. Call us for a same-day service visit to recalibrate or replace the sensor. Don't wait.

Children ages 5 to 14 are at highest risk around garage doors. They're curious, they move quickly, and they don't understand the danger. A closing door can crush fingers, hands, or worse. Many accidents happen in the driveway while parents are loading the car or backing out. The child darts under the closing door. The photo eye misses them. The auto-reverse doesn't trigger fast enough.
If you have young children, test your safety systems monthly. Better yet, teach your kids never to play near the garage door opening. Keep the remote away from them. If your door opener is older than 10 years, the safety sensors may not meet current standards. We recommend upgrading to a modern opener with enhanced safety features.

Gervais winters are harsh. Temperature swings, moisture, and freeze-thaw cycles damage photo eye lenses and corrode sensor connections. I've seen photo eyes fail specifically because condensation built up inside the lens housing during our wet season. The sensors looked fine from outside but couldn't detect anything.
If your garage door is over 5 years old, the photo eye alignment may have shifted. Settling foundations, vibration from the door itself, and wind can knock sensors out of position by fractions of an inch. That's enough to break the beam. An annual safety inspection catches these issues before they become dangerous.

A professional safety inspection and photo eye alignment typically costs between 75 and 150 dollars. If sensors need replacement, add 50 to 200 dollars per sensor depending on your opener model. This is one of the best investments you can make. The cost is trivial compared to the medical bills from a crushing injury or the guilt of a preventable accident.
Garage Door Gervais offers free estimates. We test both your photo eye and auto-reverse, check alignment, clean lenses, and recommend repairs or upgrades. Schedule a free quote today or call us at 541-807-0901. If we find safety issues, we can often fix them the same day.
Your garage door safety systems are not something to ignore or procrastinate on. Test your photo eye and auto-reverse this week. If either fails, call immediately. Don't assume the problem will resolve itself or that "it usually works." Safety systems either work or they don't. There's no middle ground when children are involved.
Contact us for a professional safety inspection. We'll make sure your family is protected. Visit our safety services page to learn what we check, or reach out directly at 541-807-0901.
How often should I test my photo eye? Test it monthly by placing an object in the door's path as it closes. The door should stop and reverse within 2 seconds. If it doesn't, call for service immediately. Don't assume it will work correctly next time.
Can I realign my photo eye myself? Minor realignment is possible if you're careful, but professional alignment ensures accuracy. Sensors must be perfectly parallel. Even 1/8 inch of misalignment can cause failure. We recommend professional inspection and adjustment.
What's the difference between photo eye and auto-reverse? Photo eye detects obstacles before the door hits them and stops the door. Auto-reverse is a backup mechanism that reverses the door if it encounters resistance. Both are required for safety. Both can fail independently.
How long do photo eye sensors last? Quality sensors last 10 to 15 years, but lenses degrade faster in wet climates like Oregon's. Moisture, dust, and UV exposure reduce effectiveness over time. Inspect lenses annually and replace sensors if they show signs of wear.
Is a 10-year-old garage door opener still safe? Older openers may not meet current safety standards. If your opener is over 10 years old, we recommend a professional safety audit. Replacement is often the safest option for homes with children or frequent use.
