After nearly two decades servicing garage doors across Renton, I’ve seen too many preventable accidents. Most homeowners don’t realize their garage door system poses serious safety risks until something goes wrong.
The good news? You can identify most hazards yourself in just 15 minutes tonight.
I’m walking you through the same safety checks our team performs during service calls. These simple tests could prevent injuries to your family and save you from expensive emergency repairs down the line.

Can Your Garage Door Reverse Properly?
Your garage door should reverse immediately when it contacts an object while closing. This is your primary defense against crushing injuries, especially if you have children or pets in Renton homes.
Place a rolled-up towel or piece of 2×4 lumber flat on the ground in the door’s path. Close the door using your wall button or remote.

The door should reverse within one to two seconds of touching the object. If it doesn’t reverse, or if it pushes the object before reversing, your opener needs immediate adjustment or replacement.
I’ve responded to calls where this feature failed completely. One family in the Renton Highlands discovered the problem only after their door crushed a bicycle. Don’t wait for that call.
Test Your Photo-Eye Sensors
Those small sensors mounted six inches above your garage floor are critical safety devices. They create an invisible beam that stops the door from closing if anything breaks the connection.
Start closing your door, then wave your leg or a broom handle through the sensor beam. The door should immediately reverse. If it continues closing, your sensors are misaligned, dirty, or malfunctioning.

Pacific Northwest rain and humidity can cause sensor issues in our area. I often find spider webs, dirt, or condensation blocking the beam during service calls in King County.

Inspect Your Cables for Fraying
Stand inside your garage and look at the cables running along both sides of your door. These steel cables are under extreme tension and can snap without warning if they’re damaged.
Look for any fraying, rust, or broken strands. Even one or two broken wire strands means the cable needs replacement. A snapped cable can cause your door to fall unexpectedly, potentially causing serious injury or property damage.
Never attempt to repair or replace cables yourself. The tension involved makes this one of the most dangerous garage door repairs.

Check the Manual Release
Your emergency release handle (usually a red cord hanging from the opener rail) allows you to manually open your door during power outages. Pull the release handle when your door is completely closed.
You should be able to lift the door smoothly by hand. It should stay open at three to four feet without assistance. If the door is extremely heavy, falls rapidly, or won’t stay open, your springs are likely broken or failing.
Washington experiences occasional winter power outages. You need to know this system works before an emergency traps your car inside. For more detailed guidance, read our article on How To Safely Test Your Garage Door’s Safety Features.
Examine Hardware and Moving Parts
Look closely at all hinges, roller brackets, and mounting hardware while your door is closed. Watch for loose screws, cracked brackets, or worn rollers.

Manually open and close your door halfway while observing the springs, cables, and rollers in motion. Listen for grinding sounds, watch for jerky movements, or notice if one side moves faster than the other. These indicate mechanical problems requiring professional attention. If your door has extensive damage or is beyond repair, consider exploring our New Garage Doors options.
