Here's what most homeowners don't realize about garage door safety: your door is one of the heaviest moving objects in your home, and a malfunctioning one can injure or kill. A standard two-car garage door weighs 300 to 500 pounds. When the safety systems fail, that weight becomes a genuine hazard. Most San Jose homeowners never test the basic protective features that prevent accidents. Let me walk you through what actually matters.
Your garage door opener should have an auto-reverse mechanism. This safety device forces the door to stop and reverse direction if it hits an object or person during closing. It's not optional. It's the law in California.
Test it monthly. Place a 2x4 piece of wood on the garage floor. Close the door. When it touches the wood, it should reverse immediately. If it doesn't, stop using that opener. Call us for a same-day inspection and repair.
Many openers lose this sensitivity over time. Springs weaken. Sensors drift out of alignment. You won't know until you test it. I've seen doors that would have seriously injured a child because the auto-reverse stopped working three years ago.
Photo eyes are small infrared sensors mounted on each side of your garage door frame, about 6 inches off the ground. They create an invisible beam. If anything breaks that beam while the door is closing, the door stops and reverses. These are equally critical to your safety setup.
Clean your photo eyes monthly. Dust and spider webs block the beam. A blocked beam means the door won't stop for a child or pet in its path. Check that both eyes are properly aligned. One pointing slightly left or right renders both useless.
If your door closes even when something blocks the beam, your photo eyes are failing. This is a genuine emergency. Don't ignore it. Visit our safety services page to understand your options.

The sides of your garage door have panels that fold and bend as it opens and closes. These create natural pinch points. Children can lose fingers or hands in seconds. The spaces between panels can trap clothing and hair.
Teach your children to stay away from the sides of the door while it's moving. Never let them play near the garage door. Keep remote controls away from kids. If your door doesn't have pinch point guards, ask about adding them during your next service call.
This ties directly to our detailed guide on garage door safety for kids and pets. That post covers additional hazards specific to families with young children or animals.
Garage door springs don't just break. They fail violently. A snapped spring can whip through the garage and cause serious injury. Springs last 7 to 9 years under normal use, then the metal fatigues.
Never attempt to replace or adjust springs yourself. This isn't a DIY project. The tension is extreme. People have died doing this work. Professional inspection costs less than an emergency repair. We can estimate your spring replacement cost during a free inspection.
If your door won't open or moves slowly, a spring may be failing. Call immediately. Don't force it open with the opener.
Your garage door has a manual release cord inside the garage. If the opener fails, you should be able to open the door by hand. Test this quarterly.
Pull the cord. The door should disengage from the opener. Push or pull the door gently. It should move smoothly. If it's stuck, binding, or extremely heavy, springs or cables are likely damaged. Schedule service before relying on an auto-opener that might fail when you need it most.
Walk to your garage. Test your auto-reverse. Clean your photo eyes. Check that the door opens and closes smoothly. If anything feels off, call us at (669) 348-2817 for a free safety assessment.

How often should I test my garage door safety features? Test auto-reverse and photo eyes monthly. Pull the manual release cord and test manual operation quarterly. These quick checks take five minutes and catch problems before they cause injury.
What's the cost to replace photo eyes or sensors? Photo eye replacement typically runs between $150 and $300 for both sensors, including labor. Installation is quick. We provide exact pricing after inspection.
Can I adjust photo eyes myself? Alignment is straightforward, but misalignment often indicates deeper issues. We recommend professional inspection to rule out opener problems or wiring damage.
Is my garage door opener still under warranty? Most openers have a one to five year parts warranty. Bring your documentation to your appointment, and we'll verify coverage before recommending repairs.
What should I do if my door won't reverse? Stop using it immediately. Don't attempt to repair it yourself. Call (669) 348-2817 for same-day emergency service.
