Does Your Garage Door Have Auto-Reverse? A Stonington Safety Check
2026-05-01 7 min read
A customer called last Tuesday asking if her garage door would stop if her kid ran underneath it. The honest answer? It depends on whether her opener has a proper auto-reverse safety system. That five-minute conversation probably saved her family from a serious injury.
Auto-reverse is the safety feature that stops and reverses your garage door if it encounters an obstacle.a toy, a pet, or worse, a person. Federal safety standards have required this on new openers since 1993, but plenty of older systems in Stonington and throughout Connecticut lack this critical protection. If your garage door doesn't have it, you're gambling with child safety.
What Auto-Reverse Actually Does
Auto-reverse operates through two mechanisms working together. The first is mechanical: a reversing mechanism that detects excessive force or pressure on the door. The second is electronic: photo eye sensors (those small infrared devices on either side of your garage opening) that detect movement in the door's path.
When either sensor triggers, the opener reverses direction immediately. A properly functioning auto-reverse system stops a closing door in about half a second. That sounds quick, but it's the difference between a minor scare and a trip to the emergency room.
The photo eye is the workhorse here. It sits roughly six inches above the ground on both sides of your door opening. If anything.a child's tricycle, a cardboard box, even a cat.breaks that invisible beam, the door stops. No exceptions.
Why Older Systems Fail
Garage doors installed before the mid-1990s often lack auto-reverse entirely. Even doors from the early 2000s might have sensors that are misaligned or covered in dust and cobwebs. I've seen photo eyes pointed at the wall instead of across the opening. I've seen them buried under years of garage grime.
The cost to upgrade an older system is reasonable. A new opener with built-in auto-reverse and photo eye sensors typically runs $300,$600 installed, depending on your door type and electrical setup. That's a fraction of what a medical emergency costs.
Testing Your Current System
You can do a basic test yourself. Close your garage door and place a 2×4 block of wood across the opening, centered. Press the close button. A properly functioning auto-reverse door should stop and reverse within an inch or two of touching the wood.
Never test with your hand or any body part. Ever.
If your door doesn't reverse, or reverses slowly, call a professional. Stonington Garage Doors can inspect your system, test the photo eye alignment, and recommend upgrades if needed.

Child Safety Goes Beyond Auto-Reverse
Auto-reverse stops accidents, but it's not a substitute for supervision. Kids are curious. They'll chase moving doors, hide underneath them, and test every button they find. The best safety practices combine technology with common sense.
Teach children that garage doors are not toys. Keep the remote out of reach. Never allow unsupervised play near the garage opening. Consider a wall-mounted button with a protective cover.something a small child can't easily press.
