Crush Prevention Systems: Protecting Your Family

December 28, 2025 6 min read

Garage doors are the largest moving objects in most homes, and safety should be a top priority. Modern crush prevention systems have made garage doors safer than ever, but understanding how these systems work helps ensure your family stays protected.

The Auto-Reverse Feature

Since 1993, all garage door openers sold in the United States must include an auto-reverse mechanism. This feature causes the door to stop and reverse direction if it encounters an obstruction while closing. The system works through a sensor that detects resistance. If the door hits something, it immediately reverses to prevent injury or damage.

Photo-Eye Sensors

Also mandated since 1993, photo-eye sensors create an invisible beam across the garage door opening about six inches above the floor. If anything breaks this beam while the door is closing, the door immediately stops and reverses. These sensors are essential for preventing injuries to children, pets, and anyone who might walk into the door's path.

Testing Your Safety Systems

Monthly testing ensures your safety systems are working properly. For the auto-reverse test, place a roll of paper towels on the ground in the door's path and close the door. It should reverse upon contact. For the photo-eye test, start closing the door and wave an object like a broom through the sensor beam. The door should immediately reverse.

Maintaining Your Safety Features

Keep photo-eye sensors clean and properly aligned. They should face each other directly across the door opening. If one gets bumped out of alignment, the door may not operate correctly. The sensors usually have indicator lights that show when they're properly aligned.

When to Upgrade

If your garage door opener was manufactured before 1993, it likely lacks these essential safety features. Upgrading to a modern opener is highly recommended, especially if you have children or pets. The investment in a new opener is minor compared to the peace of mind it provides.

Additional Safety Measures

Beyond the required safety features, consider additional precautions. Never let children play with garage door controls. Keep remote controls out of reach of young children. Teach family members to wait for the door to fully close before walking away. Regular professional maintenance ensures all safety systems function correctly.

Your family's safety is worth the investment in modern safety features and regular maintenance. Contact Garage Door Pantego to assess your current system and discuss any upgrades that might benefit your home.
