A customer called last Tuesday morning. Her 4-year-old had ducked under the closing door in the driveway. The auto-reverse kicked in. The door stopped and reversed upward within a fraction of a second. No injuries. No trauma beyond a scared kid and a grateful parent. Without that one safety feature, the outcome would have been catastrophic. Auto-reverse technology isn't a luxury in Onalaska, WA. It's the difference between a functioning childhood and a permanent tragedy.
Auto-reverse is a motorized safety mechanism that detects an obstruction and reverses the garage door's direction instantly. When the door encounters resistance during closing, sensors trigger the opener to stop and pull the door back up. Federal safety standards have required this feature on all residential garage door openers since 1993, but many older systems lack it or have degraded sensors.
The system works through two primary detection methods. Mechanical sensors detect physical contact with an object in the door's path. Photoelectric sensors (often called photo eyes) use infrared light beams across the garage opening. If something interrupts the beam, the door stops before closing. Most reliable setups use both technologies working together.
Many Onalaska homes were built in the 1980s and 1990s. A garage door opener from that era might still close every day without complaint, but its safety sensors may be failing silently. The photo eye lenses accumulate dust and spider webs. The mechanical sensors lose sensitivity. You won't notice until the system fails.
I've responded to emergency calls where homeowners discovered their auto-reverse hadn't functioned in months. The door would close fully on a box, a trash can, even a bicycle. The owners had no idea because they never tested it. If a child had been in the way, prevention becomes hindsight.
The cost of replacing an aging opener with a modern, safety-certified unit is far less than the cost of a preventable injury.

The U.S. Consumer Product Safety Commission reports that garage door accidents injure an average of 20,000 people annually. Most are children under 15. Nearly all of those injuries occur because auto-reverse systems either weren't present or weren't functioning properly.
A garage door weighs 300 to 400 pounds. When it closes at full force, it generates crushing power equivalent to a loaded truck wheel. A child's skull offers minimal resistance. Many injuries leave kids with permanent neurological damage, even when they survive.
Testing your auto-reverse takes 30 seconds. Place a 2x4 block of wood under the closing door. The door should reverse on contact. Do this monthly. If your door doesn't reverse, stop using the opener and schedule a repair with Garage Door Onalaska today.
Photo eyes are the unsung heroes of child safety. These sensors sit on either side of your garage opening, roughly 6 inches above ground level. They maintain a constant infrared beam. If your pet, bike, or child breaks that beam while the door closes, the door stops.
Many homeowners don't realize their photo eyes are misaligned. A slight bump from a ladder or vibration from traffic can throw them off by millimeters. Once misaligned, they no longer detect objects in the door's path. We've found photo eyes pointing at trees, at the ground, or at angles that miss the beam entirely.
You can test alignment by standing in the garage and watching both sensors during operation. Both eyes should glow red when the door is moving. If one doesn't light up, alignment is lost. We recommend a professional photo eye safety check at least once per year, especially if you have young children or pets using the garage regularly.
Years ago, before auto-reverse became standard, garage door accidents were far more common. Parents didn't worry about their children because they didn't know they should. Now we know better. We know that one faulty sensor can change a family's life forever.
Nearby Lacrosse and other Onalaska suburbs share the same risk profile. Older homes, older openers, and families who assume their equipment is safe because it still functions. It's a dangerous assumption. Your garage door closing force hasn't diminished with age. Only the safety systems have.
Don't wait until an accident forces you to act. Garage Door Onalaska offers free safety estimates and can typically arrange same-day service if repairs are needed. We'll test both your auto-reverse mechanism and photo eye alignment at no cost.

How often should I test my garage door auto-reverse? Test your auto-reverse monthly by placing a block of wood under the closing door. The door should stop and reverse immediately on contact. If it doesn't, call for repair same-day service to avoid accidents.
What does it mean if my photo eye glows yellow instead of red? A yellow light typically indicates the photo eye is misaligned or the lens is obstructed by dirt, cobwebs, or debris. Clean the lens with a soft cloth and check alignment. If it still glows yellow, realignment or replacement is necessary.
Can a garage door auto-reverse fail without warning? Yes. Sensors degrade gradually. You won't notice failure until testing reveals it. Monthly testing catches problems before an accident occurs.
Are older garage door openers without auto-reverse still legal? They're legal to own but illegal to install in new construction or major replacements. If your opener predates 1993, it lacks required safety features and should be upgraded.
How much does auto-reverse repair or replacement typically cost? Photo eye realignment or cleaning is often free. Sensor replacement runs 50 to 150 dollars. Full opener replacement ranges from 300 to 800 dollars depending on the model. Call for a specific estimate.
