Your garage door gets used more than almost any other moving part of your home — probably twice a day, every day, for years without a second thought. That makes it easy to ignore until something goes wrong. The good news: most warning signs show up early, and you can catch them yourself with a flashlight and about 20 minutes on a Saturday morning.
Walk through IDA’s safety checklist to check your springs, cables, sensors, and auto-reverse function yourself before you assume everything’s fine — here’s what that actually looks like in practice.
1. Look at Your Springs and Cables
Stand back and visually inspect the springs above the door (or beside it, for extension springs) and the cables running along the tracks. You’re looking for rust, fraying, gaps between coils, or any visible stretching. Never try to adjust or remove a torsion spring yourself — they’re under enormous tension and are genuinely dangerous. If something looks off, that’s a call-a-pro moment, not a DIY one.
2. Test the Auto-Reverse Safety Feature
This is the single most important safety check on this list. With the door fully open, place a 2×4 board flat on the ground in the door’s path and hit the close button. The door should touch the board and reverse immediately. If it doesn’t reverse — or it keeps closing on the board — stop using the opener and call a technician. This feature exists to prevent the door from closing on a person, pet, or car, and it should never be skipped.
3. Check the Photo-Eye Sensors
Look for the two small sensors mounted a few inches off the ground on either side of the door track. Wave a broom handle or your foot through the beam while the door is closing — it should stop and reverse. Make sure the sensors are clean, properly aligned, and not being blocked by stored items, leaves, or cobwebs, which is one of the most common (and easiest to fix) causes of a door that won’t close properly.
4. Run a Balance Test
Disconnect the opener by pulling the emergency release cord, then lift the door about halfway by hand. A properly balanced door will stay in place on its own. If it falls or shoots upward, the springs are out of balance — this puts extra strain on your opener motor and is worth having a professional address before it leads to a bigger repair.
5. Inspect Tracks, Rollers, and Hardware
Walk the length of both tracks looking for dents, gaps, or debris, and check that rollers spin freely without grinding or wobbling. While you’re at it, give all visible bolts and brackets a check with a wrench — vibration from daily use loosens hardware over time, and tightening it now is a lot cheaper than replacing a track later.
Why This Matters Beyond a Quiet Door
These checks line up with what’s recommended during Garage Door Safety Month, held each year in May to raise awareness of at-home hazards tied to garage doors and openers. The reminder to “Look, Listen, Learn, and Remember” applies just as well any time of year — a five-minute check now can catch a problem before it becomes a Saturday-morning emergency call.

When to Call In a Professional
If any of these checks turn up something questionable — a spring that looks worn, an auto-reverse that doesn’t trigger, or a door that won’t stay balanced — don’t try to fix it yourself. Springs and cables under tension cause thousands of ER visits every year. Superior Door Service, Inc. has been repairing and installing garage doors across the Kansas City metro since 1955, and we offer same-day service for exactly these kinds of issues.
