Serving Wellington, we see this problem again and again: homeowners skip basic safety checks, then face emergency repair bills that could have been prevented. Your garage door has two critical safety systems that cost almost nothing to test right now. Both take under five minutes. Skipping them puts your family at risk and your wallet in danger.
Your modern garage door has auto-reverse and photo eye sensors. These aren't luxuries. They're legally required on all residential doors manufactured after 1993. Auto-reverse stops and reverses the door if it hits an object. Photo eyes are sensors that detect motion in the door's path and prevent it from closing. See our guide: Smart Garage Door Technology Cost in Wellington.
Both systems fail silently. You won't notice until someone gets hurt or you call for a repair.
Close your garage door completely. Place a piece of scrap wood, a rolled-up towel, or a brick on the floor in the door's path. Press the close button on your remote or wall button. The door should reverse before it touches the object. See our guide: Garage Door Insulation in Wellington.
If it doesn't reverse, stop using that door immediately and call for service. A door that doesn't auto-reverse can crush fingers, hands, or worse. This is the most critical safety feature on your door.
Test this monthly. Seasonal temperature changes and normal wear can shift the door's balance and affect sensor calibration.
Photo eyes are small sensors mounted on each side of the door frame, about 6 inches off the ground. They communicate with an invisible infrared beam. If that beam is broken, the door won't close.
Walk slowly across the beam's path while the door is closing. The door should reverse. Test from both sides. If the door closes regardless of your movement, the sensors need adjustment or replacement.
Dust, spider webs, and misalignment kill photo eyes all the time. Wipe the lenses with a soft cloth. If the door still doesn't reverse, the sensors are out of alignment and need professional adjustment.

You can clean photo eye lenses yourself. Beyond that, stop. Misaligned sensors look fine but don't work. Forcing adjustments without proper tools can damage the wiring or housing. A botched sensor repair runs $150 to $300. A pro inspection and fix costs less.
The same applies to auto-reverse calibration. The door's balance, spring tension, and sensor sensitivity all interact. Changing one without understanding the others creates new problems. That's when a $100 issue becomes a $400 repair.
If your safety tests fail, get a same-day estimate from Wellington Garage Doors. We'll diagnose what's wrong and give you the actual cost before we touch anything.
If your door is older than 10 years, both systems may be near the end of their lifespan. Sensors degrade gradually. Springs lose tension. Even if everything passes today, a pre-emptive inspection catches wear before failure.
For homes with young children, safety goes beyond auto-reverse and photo eyes. Learn what additional protections matter in our guide on garage door safety for child protection in Wellington. It covers remote access, accidental activation, and entrapment risks parents often miss.
Springs are another major safety concern. If your door opens slowly, closes unevenly, or makes loud banging sounds, the springs are likely damaged. Don't wait for a complete failure. Read our breakdown of when a broken garage door spring repair costs more as DIY to understand why professional replacement saves money long-term.
Once you've tested auto-reverse and photo eyes, write down what you found. Photos help too. When you call for service, you've already narrowed down the issue. That means faster diagnosis and lower labor costs.
Most safety repairs fall into three categories: sensor cleaning (free if you do it, $50 if we do it), sensor adjustment ($75 to $125), or sensor replacement ($150 to $300). Springs and openers cost more, but they fail rarely if you catch small problems early.
Safety is never the place to save money. A $150 photo eye replacement today beats a $5,000 injury claim tomorrow. Schedule your safety inspection and get peace of mind.
Call (440) 901-5031 or use our contact form to arrange a visit. We'll test both systems, identify any issues, and give you transparent pricing. No surprises, no pressure.
How often should I test my garage door's safety features? Test auto-reverse and photo eyes monthly. Seasonal changes, dust buildup, and normal wear can shift alignment. Monthly checks catch problems before they become dangerous or expensive.
Can I adjust my photo eye sensors myself? You can clean the lenses with a soft cloth. Beyond that, leave adjustments to professionals. Misaligned sensors look fine but fail silently. Improper adjustment creates new problems costing $200 to $400 in repairs.
What does auto-reverse actually do? Auto-reverse stops the door and reverses it upward if it hits an object during closing. This prevents crushing injuries and property damage. It's legally required on all residential doors built after 1993.
How much does a photo eye replacement cost? Photo eye sensor replacement typically ranges from $150 to $300 per side, depending on the opener model and whether wiring needs repair. Getting an estimate first prevents budget surprises.
Why is my photo eye not working even after I cleaned it? Cleaning helps, but misalignment is the most common culprit. If sensors point even slightly past each other, the infrared beam breaks and the door closes regardless. This requires professional realignment, not cleaning.
