Families childproof outlets, lock up cleaning supplies, and test smoke detectors twice a year. Far fewer give the same attention to the garage door, even though it’s often the largest moving object in the house.
A typical two-car door weighs well over 100 pounds and moves on a system of springs and cables under heavy tension. For many families, it’s also the door they use most, which makes it a major entry point to the home.
A few minutes of attention each month can help keep that door safe for kids, pets, and everyone else in the house. If you notice unusual noises, damaged cables, or problems with the door’s operation, it’s best to seek professional assistance.

Protecting Kids and Pets: Test the Auto-Reverse Monthly
Since the early 1990s, federal rules have required automatic garage door openers sold in the U.S. to include an auto-reverse safety system. Most openers rely on two features: a pair of photo-eye sensors near the floor and a force setting that reverses the door if it meets resistance.
Those features only protect your family if they work. Sensors get bumped, dirty or misaligned, and force settings drift over time. Run two quick tests once a month:
- The sensor test. Start closing the door, then wave a broom handle or your foot through the sensor beam. The door should stop and reverse right away.
- The resistance test. Lay a roll of paper towels or a 2×4 flat on the floor where the door closes. When the door touches it, it should reverse.
If the door fails either test, stop using the opener and have it inspected. In the meantime, use the wall button only while you’re watching the door close.
A few house rules help too. Mount the wall button at least five feet high, out of small children’s reach. Keep remotes away from kids, and teach them that the garage door isn’t a toy. And never try to beat a closing door by running or rolling under it.
Springs and Cables: Look, Don’t Touch
The springs that lift your door store a tremendous amount of energy. Torsion springs, which are mounted on a bar above the door, are wound tight. Extension springs, which run along the side tracks, stretch every time the door closes. The cables that connect them to the bottom of the door carry the same load.
When these parts fail, or when someone tries to adjust them without the right tools, they can release that energy violently. This is where many of the most serious garage door injuries come from.
You can safely look for trouble:
- A visible gap in a torsion spring
- Frayed, rusted or loose cables near the bottom corners of the door
- A door that hangs crooked or feels very heavy when lifted by hand
- Extension springs without a safety cable running through them
If you see any of these, stop using the door and call a trained technician. Don’t loosen bolts on the bottom brackets, and never try to unwind or adjust a spring yourself.
Close the Security Gaps
For many homes, the garage is the easiest way in. A few habits make it much harder for anyone to use it that way:
- Treat the house door like a front door. Keep the door between the garage and the house locked, ideally with a deadbolt.
- Don’t leave the remote in your car. A remote clipped to the visor of a car parked outside is an open invitation if the car is broken into. A keychain remote or smartphone control is safer.
- Check your opener’s age. Openers made before the mid-1990s often use fixed codes that can be copied. Modern openers use rolling codes that change every time you press the button.
- Use smart alerts. Many newer openers can send a phone notification when the door opens and let you close it remotely, so you’re never left wondering whether you shut it.
- Secure the emergency release. On some doors, a thief can use a hooked tool through the top gap to pull the release cord. A release shield, a small guard sold for this purpose, helps prevent this without blocking the release in an emergency.
- Cover the windows. If your garage has windows, frosted film or blinds keep passersby from seeing what’s inside, or whether a car is home.
Know What to Do When the Power Goes Out
Storms and outages are when garage doors catch families off guard. Everyone old enough to drive should know how to open the door by hand.
Most openers have a red emergency release cord hanging from the trolley. With the door fully closed, pull the cord to disconnect the door from the opener, then lift the door by hand. A door that’s balanced should lift without much effort. If it feels extremely heavy, a spring may be broken, so don’t force it.
A few cautions:
- Avoid pulling the release while the door is open. If a spring is weak or broken, the door can slam shut.
- Re-engage the trolley after power returns. Most reconnect when you run the opener once.
- If your home loses power often, consider an opener with battery backup. Some states, including California, now require it on new openers.
Practice once on a calm day so nobody is learning it for the first time in the dark.
A Family Garage Safety Checklist
Print this and keep it on the garage wall.
Monthly
- ☐ Test the photo-eye sensors and the auto-reverse
- ☐ Look over springs, cables and rollers for visible wear
- ☐ Listen for new grinding, squealing or banging
Twice a year
- ☐ Lubricate hinges, rollers and springs with a garage-door spray
- ☐ Check the balance: disconnect the opener, lift the door halfway, and let go. It should stay put
- ☐ Tighten loose bolts on hinges and track brackets
- ☐ Practice using the emergency release
Anytime
- ☐ Keep remotes and the wall button out of children’s reach
- ☐ Keep the door to the house locked
Call a professional right away if the door fails a safety test, a spring or cable looks damaged, the door is off its track, or it won’t stay balanced. Spring and cable work is never a DIY job. The right technician will explain what’s wrong, show you the worn part, and test every safety feature before leaving.
