Serving Sherwood, we see this problem again and again: homeowners don't realize their garage door's auto-reverse feature is broken until a child or pet gets hurt. This safety mechanism detects an obstruction and reverses the door before it causes serious injury. Federal law has required it since 1993. If your opener doesn't have it or it's not working properly, you're operating an unsafe door.
Auto-reverse is an electronic safety system that stops and reverses a closing garage door when it encounters resistance. When the door hits an object, person, or pet, a force sensor or electronic eye triggers the motor to reverse immediately.
This isn't optional equipment. The Consumer Product Safety Commission (CPSC) mandates auto-reverse on all residential garage door openers. Without it, a 400-pound descending door can crush fingers, hands, and worse. Children are most vulnerable because they don't understand the danger and move unpredictably.
The system works two ways. Mechanical force sensors detect physical pressure. Electronic photo eyes sense an infrared beam break, triggering reversal before contact happens. Both methods save lives when functioning correctly.
Testing takes 30 seconds and requires no tools. Close your garage door normally. As it descends, place a wooden block (2x4 or similar) on the ground in its path. The door should hit the block and immediately reverse upward. Never use your hand or arm.
If the door doesn't reverse, stop using it. This is a critical safety failure. An opener without working auto-reverse needs immediate attention from a licensed technician.
We also recommend testing your photo eye monthly. Place an object in the beam's path while the door closes. It should reverse before making contact. If either test fails, your door poses a genuine hazard to family members and guests.

Photo eye misalignment is the leading culprit. These infrared sensors sit on each side of the garage opening, roughly 6 inches from the ground. Cobwebs, dirt, or accidental bumps knock them out of alignment. When the beams don't meet properly, the safety system can't function.
Force sensors wear out over time. They're designed to detect pressure changes, but dust, corrosion, and mechanical stress degrade them. A sensor that worked five years ago may no longer respond accurately.
Wiring problems also disable auto-reverse. Loose connections, rodent damage, or corroded terminals break the circuit between the sensor and motor. The opener may still run, but the safety logic fails silently.
Opener age matters too. Models more than 20 years old may have outdated safety components that can't be repaired. Replacement often becomes the safest and most cost effective option. Learn when upgrading your opener makes financial sense for Sherwood homes.
Children under 8 are at highest risk from garage door injuries. They don't understand the door's weight or speed. Some pull on it, others hide underneath, and some simply wander into the path.
Auto-reverse only works if it's actually working. A broken photo eye or failed force sensor leaves your child completely unprotected. This is why we strongly recommend testing monthly and having any failures repaired immediately.
If you have young children or pets, consider upgrading to an opener with both photo eye and force sensor backup. That redundancy means even if one system fails, the other provides protection. Our team can provide a free estimate for safety upgrades tailored to your family's needs.
Photo eye realignment and cleaning often costs under $100. Replacing a failed photo eye sensor runs $150 to $300 for parts and labor. Force sensor replacement typically costs $200 to $400.
If your opener is old or multiple safety components are failing, full replacement may be more sensible than chasing repairs. An opener replacement with modern safety features costs significantly more upfront but eliminates recurring failures. Read our guide to garage door cost factors in Sherwood to understand pricing better.
Schedule a technician visit for a detailed diagnosis. We offer same-day appointments across Sherwood and can provide an estimate before any work begins. A safety inspection takes minutes and protects your family for years.
Monthly testing prevents surprises. Clean photo eye lenses with a soft cloth. Ensure nothing blocks the infrared beam. Keep the garage area clear of debris that could trigger false reversals.
Have your opener serviced annually. A professional tune-up catches worn sensors and loose wiring before failure. Maintenance is far cheaper than emergency repair after an injury.
Don't ignore warning signs. If your door hesitates, reverses unexpectedly, or moves slowly, get it inspected. These behaviors often signal failing safety components. Contact us for a professional garage door safety assessment in Sherwood.
Your auto-reverse feature is your family's last line of defense. Keep it working.
How often should I test my garage door's auto-reverse? Test monthly by placing a block in the door's path as it closes. The door should reverse immediately on contact. This takes 30 seconds and catches failures before someone gets hurt.
Can I repair auto-reverse myself? Photo eye alignment you can attempt, but sensor replacement requires technical knowledge and tools. Incorrect installation leaves your door unsafe. Always hire a licensed technician for sensor repairs or replacements.
What if my door is older than 20 years? Safety components degrade over time. Older openers may lack modern redundancy features. Replacement is often safer and more reliable than repeated repairs on aging equipment.
Does auto-reverse work in power outages? No. Auto-reverse requires electricity to function. Battery backup systems keep the door moving during outages, but safety sensors still need power to operate.
Are there garage door openers with extra safety features? Yes. Modern openers include dual sensors, battery backup, and smartphone alerts. Some models notify you if the door is left open. Ask your technician about options that fit your family's needs and budget.
