Garage Door Safety in Somerset: Auto-Reverse & Photo Eye Explained
2026-08-28 5 min read
In our years serving Somerset, we've seen this problem again and again: homeowners don't realize their garage door lacks basic safety features that could prevent serious injury. Auto-reverse mechanisms and photo eye sensors aren't luxury add-ons. They're essential safeguards that stop a closing door before it causes harm to a child, pet, or vehicle.
Why Garage Door Safety Matters in Somerset Homes
Your garage door weighs between 300 and 400 pounds. When it closes, it generates force equivalent to a small car. Without proper safety systems, a malfunctioning door can cause crushed fingers, broken bones, or worse. See our guide on garage door springs in somerset: repair cost & when to replace.
Somerset sits in the Texas Hill Country where families spend time in and around their garages year-round. Whether you're parking your truck or your kids are playing nearby, the risk is real. The good news? Modern safety features are affordable and effective.
Federal law has required new garage door openers to include auto-reverse since 1993. If your system predates that, or if you've never tested these features, now's the time to act. Read about garage door repair in somerset: why it won.
Auto-Reverse: How It Works and Why You Need It
Auto-reverse is a mechanical or electronic device that stops and reverses a closing garage door if it encounters an obstacle. When the door hits something solid, sensors detect the resistance and trigger the motor to stop, then back the door up.
Think of it this way: your child's toy sits under the door. The door comes down. Within half a second, auto-reverse detects the obstruction and pulls the door back up. No crushed toy. No crushed hand.
Some auto-reverse systems use mechanical force-sensing. Others rely on electronic sensors. Both work, though electronic systems tend to be more sensitive and faster. The best part? Testing is simple. Place a 2x4 block under the door. Close it. The door should reverse within 2 seconds of contact.
If your door doesn't reverse, that's a red flag. Our team at Somerset Garage Doors can test and repair or replace your auto-reverse mechanism. Schedule a free quote today) and we'll assess your current setup.
Photo Eye Sensors: Your Second Line of Defense
Photo eyes are infrared sensors mounted on each side of your garage door frame, about 6 inches above the ground. They create an invisible beam across the door's path. If anything breaks that beam while the door is closing, the door stops immediately.
Photo eyes catch what auto-reverse might miss. A person walking through. A pet. A bicycle leaning at an angle. These sensors are incredibly sensitive and reliable.

Photo eyes require clear sightlines. Dirt, cobwebs, or misalignment can cause false stops or failure to detect obstacles. We recommend checking them monthly. Wipe the lenses clean. Make sure nothing blocks the beam. If your door stops randomly or won't close, photo eye malfunction is often the culprit.
Testing Your Safety Features at Home
Before calling for service, run these tests yourself. First, with the door fully open, press the close button. Watch the door descend. Does it move smoothly without jerking? That's a good sign.
Next, place your hand under the descending door (don't put it in harm's way, just near the threshold). The door should stop when your hand breaks the photo eye beam. If it doesn't stop, that's a safety issue requiring immediate attention.
Finally, the 2x4 test for auto-reverse. Place a small block of wood under the descending door. If the door reverses, you're good. If it continues pushing down, your auto-reverse is failing.
If any test fails, don't delay. A faulty safety system puts your family at risk. Learn more about our safety services) or reach out for an estimate.
Child Safety and Peace of Mind
Parents worry about garage doors. And they should. Children are naturally curious. They see a button, they push it. They crawl under a descending door out of impulse, not malice.
Photo eyes and auto-reverse give you peace of mind. They work 24/7 without your input. They don't get tired or distracted. When properly maintained, they stop accidents before they happen.
If you have young children or grandchildren visiting often, prioritize safety upgrades. The cost is reasonable. The protection is priceless.
