Test the garage door safety reversal system monthly and stop using the automatic opener if the door doesn't reverse properly. A heavy moving door isn't something to troubleshoot casually around kids, pets, cars, or storage.
Quick checks
- Make sure photo eyes are clean and aligned.
- Check that nothing blocks the sensor path.
- Test the door reversal according to the opener manual.
- Listen for grinding, straining, or unusual movement.
- Call for service if the door fails a safety test.
Use your opener manual
Garage door opener brands have specific safety reversal test steps. Follow the manual for your model rather than copying a random method from a forum. If the test fails, disconnect automatic use until it is fixed.
Photo eye problems are common
If the door won't close, dirty or misaligned photo eyes are a common first check. Clean lenses gently, check wiring damage you can see, and remove objects in the beam path. Don't bypass sensors.
When to call a pro
- The door doesn't reverse during the test.
- The springs, cables, rollers, or tracks look damaged.
- The door is crooked or drops quickly.
- The opener strains or the door binds.
- You are tempted to adjust springs yourself.
Good maintenance rhythm
- Test monthly, and check again after sensor bumps, opener work, storms, or any time the door behaves differently.
