The Importance of Garage Door Safety
Garage doors are among the largest moving objects in your home, weighing 200-400 pounds or more. Without proper safety features, they can cause serious injury or even death. Understanding and maintaining crush prevention systems is essential for every homeowner.
Modern Safety Features
Auto-Reverse Mechanism
Required by law, this feature causes the door to immediately reverse when it contacts an object while closing. Test monthly by placing a 2x4 in the door's path.it should reverse upon contact.
Photo Eye Sensors
Infrared sensors mounted 4-6 inches above the floor detect objects in the door's path and prevent closure. These should be:
- Properly aligned (LED indicators show status)
- Clean and free of debris
- Protected from direct sunlight interference
- Tested monthly
Entrapment Protection
Some modern openers include additional sensors that detect resistance during operation and stop the door immediately.
Testing Your Safety Systems
Monthly Test Procedure:
- Force Test: With the door closing, hold the bottom with your hands. It should reverse easily.
- Object Test: Place a 2x4 flat on the ground in the door's path. The door should reverse upon contact.
- Photo Eye Test: While closing, wave an object through the sensor beam. The door should reverse.
When to Upgrade
Consider upgrading your opener if:
- It was installed before 1993
