2026-08-04 A2Z Garage Doors
A customer called last Tuesday worried her garage door wouldn't stop if a toy ended up underneath it. That's the question that matters most: will my door hurt someone? The answer depends on whether your opener has the right safety features. Auto-reverse technology and photo eye sensors are non-negotiable. Without them, you're gambling with your family's safety. Here's what actually protects you.
Auto-reverse is the single most important safety feature on any garage door opener. When your door descends and hits an obstruction, the motor reverses direction within half a second. No crushing. No pinching. Just a door that backs up.
Federal law has required auto-reverse on all garage door openers since 1993. But older systems fail. Springs wear out. Motors lose sensitivity. The photo eye sensor that triggers the reversal gets dusty or misaligned, and nobody notices until something goes wrong.
Here's the honest truth: most openers I service in Lake Oswego still have the original sensors from installation. After 10 or 15 years, they're not as responsive as they should be. A quick safety inspection costs nothing. A child's injury costs everything.
Photo eyes are the safety sensors mounted near the bottom of your garage door frame, one on each side. They send an invisible infrared beam across your garage opening. If anything breaks that beam while the door is closing, the opener should stop and reverse immediately.
They're small. They're easy to ignore. And they fail silently.
Dust, spider webs, and condensation cloud the lens. A bumped sensor gets knocked out of alignment. The door closes anyway because the photo eye can't see the obstruction anymore. Kids, pets, and bicycles aren't always visible from the opener control button.
I recommend checking your photo eyes monthly. Wipe the lenses with a soft cloth. Make sure both sensors have a steady red or green light. If one light is out or flickering, call us right away. If you're unsure how to inspect them, we offer same-day safety inspections across Lake Oswego and the surrounding area.
Garage doors weigh between 300 and 500 pounds. They move at roughly one foot per second. The force required to stop them mid-descent is significant. Without auto-reverse, your door becomes a guillotine.
Most child injuries happen because someone was underneath the door when it closed. Not always because of a malfunction. Sometimes the remote button was pressed by accident. Sometimes a child held the wall button. Sometimes the door was already closing when a toy got kicked underneath.
That's why tamper-resistant features matter. Modern openers include wall buttons that require a two-second press to activate. Older models respond to a single touch. If you have young kids or grandkids visiting, ask about upgrading your opener's button behavior during your next safety consultation.

Safety features only work if they're maintained. Springs last 7 to 9 years before they lose tension and stop supporting the door properly. When springs fail, the auto-reverse system works harder and wears out faster. Photo eyes drift out of alignment after years of vibration.
A maintenance schedule prevents these breakdowns. We recommend annual inspections. More often if you use your door four or more times daily.
During an inspection, we test the auto-reverse by placing a 2x4 block under the closing door. We clean and realign photo eyes. We check spring tension and lubricate moving parts. We verify the wall button and remote work correctly. The cost of an estimate is free. The cost of skipping maintenance is a safety failure nobody wants.

Some features feel safe but don't actually protect you. A loud alarm when the door opens? Nice for security. Doesn't stop a closing door. A smart app that lets you check the door from your phone? Convenient. Doesn't replace photo eyes. A light that turns on automatically? Helpful. Not a safety device.
I mention this because homeowners sometimes assume their newer openers are safer just because they have more features. Safety and convenience are different things. You need both, but don't confuse them.
If your garage door opener is older than five years, your photo eyes haven't been professionally cleaned and tested, or you're simply unsure about your setup, an inspection is your next step. We'll test every safety feature and give you an honest estimate if anything needs repair or replacement.

Your family's safety isn't something to guess about. It's something to verify.
Q: How often should I test my garage door's auto-reverse? A: Monthly. Place a 2x4 block under the closing door from a safe distance. The door should reverse when it hits the block. If it doesn't, contact a technician immediately. Never test with your hand or body.
Q: Can I replace photo eye sensors myself? A: You can clean and realign them. Replacement requires opener-specific parts and proper calibration. A professional ensures they're aligned correctly and test the system. Cost is minimal compared to a safety failure.
Q: What if my garage door is from the 1990s? A: It likely has auto-reverse and photo eyes, but they may be less reliable than modern systems. An inspection will tell you whether they're functioning properly. Many older openers are worth keeping if the safety features test well.
Q: Do smart garage door systems improve safety? A: Smart apps add convenience and monitoring. They don't replace auto-reverse or photo eyes. Safety features are mechanical and electronic backups to the motor itself. Smart features work alongside them, not instead of them.
Q: How much does a garage door safety inspection cost? A: A comprehensive safety inspection is free. If repairs or parts are needed, we'll provide a detailed estimate before any work begins. No surprises, no hidden charges.
