Here's what most homeowners don't realize about garage door safety in Rehoboth: your garage door is one of the heaviest moving objects in your home, and it's operating right now with safety systems designed decades ago. Most families never test whether those systems actually work until something goes wrong. If you have kids or pets, this matters more than you think.
A garage door weighs between 300 and 900 pounds depending on the type and material. That's roughly the weight of a small car moving at head height. The auto-reverse safety feature is supposed to stop and reverse the door if it detects an obstruction. But if your photo eye sensors are misaligned, covered in dirt, or damaged, that safety net disappears entirely. I've been doing this work for 15 years around Rehoboth and the surrounding area, and I can tell you: most people never check these sensors until I point out they're not working.
Your garage door has two independent safety mechanisms, and both need to work flawlessly.
Photo eyes are infrared sensors placed near the bottom of your door frame on both sides. When the door closes, it passes through a light beam between them. If anything breaks that beam (a child, a pet, a bicycle), the door should stop and reverse. These sensors are incredibly effective, but only when they're clean and properly aligned. Dust, spider webs, and misalignment knock them out of service without you knowing it.
Auto-reverse springs and the force-reversal mechanism provide a mechanical backup. If the door hits something while closing, the opener should sense the resistance and reverse. Modern openers have adjustable force settings that let technicians calibrate how sensitive this response is. Too loose, and it won't catch a real obstruction. Too tight, and it becomes a nuisance.

I recommend every Rehoboth homeowner perform a simple monthly test. Close your garage door, then place a piece of wood (a 2x4 works perfectly) on the floor in the door's path. Activate the close button. When the door contacts the wood, it must stop and reverse within one second. If it doesn't, your auto-reverse is either miscalibrated or failing.
Next, check your photo eyes. Stand to the side and watch the red and green lights on the sensors as the door closes. Both should stay lit and green. If either flashes, dims, or turns red, the sensors need cleaning or realignment. Wipe the lens with a soft cloth first. If the problem persists, that's your signal to call for a service visit.
We've written a complete guide on garage door safety checks every Rehoboth homeowner should do monthly if you want step-by-step details beyond the basics.
If you have young children or pets, this becomes even more critical. The Consumer Product Safety Commission reports hundreds of garage door related injuries annually, many involving kids. A child's hand, head, or fingers getting caught in a closing door is preventable with proper safety systems and parental awareness.
Never let children play in or near the garage while the door is operating. Teach them that the garage door opener is not a toy. Keep the remote control away from kids. Most importantly, make sure your photo eye and auto-reverse systems are tested and working. A single missed safety check could mean the difference between a close call and a tragedy.
If your door is more than 10 years old, the safety components may be degraded. Springs typically last 7 to 9 years, and when they start failing, the entire door balance changes, which affects how the auto-reverse responds. If your door is making unusual sounds, moving unevenly, or if your safety tests show any hesitation, schedule a service appointment. We offer a free same-day estimate for most Rehoboth properties, and our technicians can spot wear you can't see.

What does a photo eye do on a garage door? Photo eyes are infrared sensors that detect obstructions in the door's path. If anything blocks the beam while the door is closing, the door stops and reverses. They're a critical child and pet safety feature that must be kept clean and aligned to work properly.
How often should I test my garage door's auto-reverse? Test your auto-reverse safety every month. Place a 2x4 board in the door's path and activate the close button. The door must stop and reverse within one second. If it doesn't, contact a technician immediately.
Can misaligned photo eyes cause the door to get stuck? Yes. Misaligned or dirty photo eyes can prevent the door from closing at all, or they may cause erratic behavior. The door may hesitate, reverse unexpectedly, or refuse to respond. Cleaning and realignment usually solve the issue quickly.
Is it safe to adjust the auto-reverse force myself? No. Force adjustment requires proper tools and training. Incorrect settings can disable the safety feature entirely or make it overly sensitive. Always have a professional handle these calibrations.
