In our years serving Rehoboth, we've seen this problem again and again: homeowners don't know what safety features their garage door has, let alone how to test them. A garage door is one of the heaviest moving objects in your home, and without proper safety mechanisms, it becomes a genuine hazard to your family. The good news? Modern garage doors include proven protective systems. You just need to understand them.
Your garage door likely has two main safety systems built in: the auto-reverse mechanism and the photo eye sensor. These work together to prevent injuries and property damage.
The auto-reverse feature stops and reverses the door's direction if it encounters resistance while closing. Think of it as a safety net. If a child's hand, a bicycle, or even a pet is under the door, the auto-reverse detects that pressure and reverses immediately. Federal law has required this on all garage door openers since 1993, but age matters. Older systems may not function reliably.
The photo eye (sometimes called a photoelectric sensor) is a beam of invisible light that runs across your garage door opening, typically about 6 inches from the ground. If anything breaks that beam while the door is closing, the door stops. This is your child safety backup system. If a child crawls under a closing door, the photo eye halts it before impact.
A safety feature that isn't tested is just a feature you hope works. We recommend testing your auto-reverse and photo eye at least twice yearly, and definitely before the busy spring and summer months when kids are around more.
To test auto-reverse, place a 2x4 piece of wood under the closing door. The door should hit the wood and reverse immediately. No hesitation, no grinding sound. If it doesn't, stop using the door and call a professional. Testing the photo eye is equally simple: close the door and interrupt the beam with your hand or foot while it's descending. The door should stop instantly.
Our team walks through proper safety reversal testing with every customer, and I've written a complete guide you can reference anytime at safety reversal testing: a complete guide for homeowners.
Many homeowners think safety maintenance is an extra expense. It's not. A single injury, especially involving a child, costs far more than preventive testing and repairs. Insurance may not cover incidents involving a garage door that failed safety tests. More importantly, you can't put a price on peace of mind.
If your auto-reverse or photo eye isn't working, the cost to repair or replace it is modest. Most sensor replacements or auto-reverse recalibrations run between $150 and $300. Compare that to emergency room visits or worse. If your door has a damaged spring (a common reason safety systems fail to engage properly), you'll want to understand the full picture. We've broken down garage door spring replacement cost in Rehoboth so you know exactly what to expect without surprises.

Springs, cables, and tracks all influence whether your auto-reverse and photo eye function properly. If your springs are worn out, the door may not close smoothly, which can trigger false auto-reverse activations or prevent proper photo eye operation. If your tracks are misaligned, the door binds, and safety systems can't respond correctly.
We inspect these components during every service call. Most homeowners find that annual maintenance costs far less than emergency repairs, and it keeps your family safe year-round. Visit our garage door safety services page to see what's included in a full safety inspection.

How often should I test my garage door's auto-reverse? Test auto-reverse at least twice per year, ideally in spring and fall. If you have young children or pets, monthly testing adds extra peace of mind. Always test before major seasonal changes.
What should I do if my photo eye is misaligned? First, check that both sensor lenses are clean and facing each other directly across the opening. If alignment looks correct but the beam isn't working, the sensors likely need replacement. Contact a professional rather than attempting repairs yourself.
Can I adjust auto-reverse sensitivity myself? Most modern openers have a sensitivity dial, but we don't recommend adjusting it without professional guidance. Incorrect settings can make the door less safe. Let us handle it during your inspection.
Why does my door sometimes reverse for no reason? False reversals often point to a misaligned photo eye, dirt on the sensors, or an issue with the springs or tracks. These problems compound safety concerns and need prompt attention from a trained technician.
Is my older garage door still safe? Doors built before 1993 may lack modern auto-reverse features. If yours is more than 20 years old, have it professionally inspected. Upgrading the opener is usually the most cost-effective solution for older doors.
