Serving Chula Vista, we see this problem again and again: homeowners don't realize their garage doors have drifted out of safe working condition until something breaks or someone gets hurt. A quick inspection catches issues early, keeps your family safe, and saves money on repairs. Here's what to check.
Start with the springs. Look at both sides of your door where the springs attach to the frame. Torsion springs (the wound metal coils above the door) typically last 7 to 9 years under normal use. If you see a visible gap or separation in the coil, or if one spring looks shorter than the other, that's a red flag. Never try to adjust or touch a broken spring yourself. The tension in those coils is lethal.
Next, trace the cables that run alongside the springs. They should be straight and intact from top to bottom. Fraying, rust, or visible slack means they're failing and need replacement soon. Check the pulleys and brackets too. Rust and loose fasteners are common in Chula Vista's coastal humidity, so corrosion here isn't unusual but it does weaken the system.
Look at the bottom seal and weatherstripping. Gaps here don't affect safety directly, but they invite pests and moisture, which accelerate rust and wear on critical parts.
This is the single most important active safety check. Modern doors have an auto-reverse feature that makes the door stop and reverse direction if it hits an obstruction. You can test it yourself in about two minutes.
Place a rolled-up towel or cardboard box on the ground in the door's path, then press the button to close. The door should hit the object and immediately reverse back up. If it doesn't, or if it hesitates, the door is unsafe for use. This feature protects children, pets, and anyone who walks under the door. Don't ignore a failed auto-reverse test.
The photo eye (also called a safety sensor) is a small electronic eye on each side of the door, about 6 inches up from the ground. These beam an invisible light across the door opening. If something blocks that beam while the door is closing, the door should reverse.
Make sure both photo eyes are clean and aligned straight across at the same height. Dust or spider webs can blind them, so wipe them gently with a soft cloth. If one eye is knocked off angle (common after kids' bikes hit it), realign it or have a technician do it.
A balanced door is safer and lasts longer. Open the door manually about halfway and let go. A properly balanced door should stay in place or drift down very slowly. If it crashes down fast or springs back up, the springs are out of balance and the opener is working overtime, which causes premature wear and increases injury risk.
You can also test opener reversal force by pressing the close button and gently placing your hand in the door's path. It should stop and reverse within a light touch. If it crushes your hand or ignores resistance, the force settings need adjustment by a professional.
When the door opens or closes, it should move smoothly with minimal noise. Grinding, squeaking, or clunking tells you something is loose or worn. Squeaking usually means lubrication is needed. Grinding or clunking points to worn rollers, damaged tracks, or cable issues. These sounds are your door asking for help before it fails completely.

Follow both vertical tracks with your eyes and fingers. Look for dents, bends, or buildup of debris. Dented tracks throw rollers off alignment and cause binding. Gently push on the door to feel if it rolls smoothly or catches. Rollers themselves wear out and should be checked during routine maintenance.
If tracks are badly bent, don't try to pound them straight. Call a technician who can assess whether replacement is needed. Misaligned tracks are a child safety issue because the door can derail or bind unexpectedly.

How often should I inspect my garage door for safety? Inspect it monthly yourself by checking springs, cables, and testing auto-reverse. Schedule a professional inspection annually or every 6 months if your door gets heavy daily use.
What does a photo eye do and why is it important? The photo eye detects objects in the door's path and signals the opener to reverse. It's critical child safety equipment. If it's misaligned or dirty, the door won't stop for obstructions.
Can I fix a broken garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Always call a licensed technician for spring repairs.
Why does my garage door reverse when closing but nothing is in the way? The photo eyes may be dirty, misaligned, or blocked by cobwebs. Clean and realign them first. If that doesn't work, the sensor may be failing and needs replacement.
