Your garage door's auto-reverse system is a lifesaver. It stops the door mid-close if something blocks it. But most homeowners in Windham never test whether it actually works. That's dangerous. Here's how to check yours right now.
The auto-reverse is your garage door's safety net. When the door descends and hits an obstacle, sensors and mechanical stops force it back up. This feature prevents crushing injuries to children, pets, and adults.
Federal law requires all garage doors installed after 1993 to have this dual safety system: photo eyes (electronic sensors) and a mechanical force-reversal mechanism. Two layers of protection. But only if you maintain them.
Photo eyes sit on each side of your garage door frame, about 6 inches off the ground. They shoot an invisible beam across the opening. When something blocks that beam, the door reverses.
Here's your test:
First, close your garage door completely. Press the button to open it. When it's fully up, press close again. Now, while the door is descending, walk slowly through the opening. Your body breaks the beam. The door should stop and reverse upward immediately.
Second, test with an object. Place a small box or stick in the door's path about halfway down. Close the door. When it hits the object, it should stop and reverse. It shouldn't crush the object.
If your door doesn't reverse, don't use it. Call a professional. A non-functioning auto-reverse is a liability and a hazard to your family. We've seen too many near misses in Windham that could have been prevented with working sensors.
Dust, spider webs, and debris block the lens. Misalignment happens when doors settle over time. Heavy rain or snow can affect the sensors too. Inspect them monthly. Wipe the lenses clean with a soft cloth.

Your opener also has a mechanical limit that reverses the door if it detects excessive downward force. This is your backup when photo eyes fail.
To test this: Close the door normally. When it's about 12 inches from the floor, place your hand flat (palm up) under the edge. The door should touch your hand, sense the resistance, and reverse. You shouldn't feel crushed or pinned.
Important: Don't use your hand as a regular test. Do this once a year, gently. If the door doesn't reverse or feels too heavy, the force adjustment needs tuning by a professional.
Garage Door Windham technicians can adjust this sensitivity during routine maintenance. Most homeowners overlook this entirely, which is why we stress testing at least annually.
Children are curious. They watch garage doors open and close. Some try to catch them. Some hide underneath. An auto-reverse protects them from serious injury, but only if it works.
Beyond testing, keep the remote control away from children. Never let kids play with the button. Teach them that the garage door is not a toy. And always use your opener's manual release in an emergency. For deeper guidance on protecting kids around garage doors, read our guide on child protection and photo eye systems.
If your auto-reverse works, document it. Keep a log. Note the date and result.
If it fails, don't delay. A broken auto-reverse is a ticking liability. Repairs cost far less than an injury. And if someone gets hurt because your door lacks a functioning safety system, your homeowner's insurance might not cover it.
Many homeowners worry about the cost of repairs. Honestly, testing is free. Most fixes run between $150 and $400 depending on what's wrong. That's a fraction of what a medical emergency would cost. For transparency on pricing, check out our guide on what garage door repairs actually cost.
Need a professional to test your system? Schedule a free safety estimate with us. We'll inspect photo eyes, test the force-reversal, and give you honest feedback about what needs work.
Auto-reverse systems fail because they're neglected. A yearly tune-up catches problems early. We lubricate tracks, test sensors, adjust force settings, and confirm everything reverses smoothly. Learn why annual maintenance matters for your garage door.
Your garage door protects your family every single day. It deserves the same care you'd give a car or your home's locks. Test it today. Call us at (330) 846-5896 if anything seems off.

How often should I test auto-reverse? Test your auto-reverse system once per month with the photo eye and once per year with the mechanical force-reversal. Monthly tests catch debris blocking sensors. Annual mechanical tests ensure the reversal mechanism hasn't drifted out of adjustment.
What if my door reverses only halfway? Partial reversal usually means the force-limit is set too high or the photo eyes are misaligned. This is a tuning issue, not a catastrophic failure. Call a technician to re-adjust both systems for full, immediate reversal.
Can I adjust the force-reversal myself? No. Most garage door openers have screws that control reversal force. Adjusting these incorrectly can make the safety system fail or cause the door to reverse unexpectedly. Always hire a professional for adjustments.
Do older garage doors need testing? Absolutely. If your door was installed before 1993, it may lack modern safety sensors. Even if it's newer, age degrades components. Test annually and consider upgrading to a modern, safety-equipped system.
Why does my garage door seem to reverse too easily now? Sensitivity can shift if the force-adjustment screw loosens over time or if your opener's internal mechanisms wear. This is a sign of needed maintenance. Have it inspected before the sensitivity drops further and stops working.
