Auto-Reverse Sensors: Protecting Your Family
2023-12-28 5 min read
# Auto-Reverse Sensors: Protecting Your Family, all garage door openers sold in the United States are required to have auto-reverse safety features. These sensors are your first line of defense against garage door injuries.
How Auto-Reverse Sensors Work
Photo Eye Sensors
Most garage doors use infrared photo eye sensors: - Two sensors installed 4-6 inches from floor, Invisible beam crosses the door opening, Door reverses when beam is interrupted, Works for people, pets, and objects
Pressure Sensors
Secondary safety feature: - Detects resistance when door contacts object, Triggers immediate reversal, Required backup to photo eye system
Why These Sensors Are Critical
Injury Prevention
Garage doors can weigh 150-400+ pounds: - Enough force to cause serious injury, Especially dangerous for children and pets, Sensors provide essential protection
Legal Requirements
Federal law mandates: - All openers manufactured after 1993 must have sensors, Regular testing recommended, Proper maintenance required
Testing Your Sensors (Monthly)
Photo Eye Test
1. Open garage door fully 2. Place object (like a box) in sensor path 3. Press close button 4. Door should reverse immediately
Pressure Test
1. Open garage door fully 2. Place 2x4 flat on ground in door's path 3. Press close button 4. Door should reverse when contacting wood
If either test fails, stop using the door and call for emergency service immediately.
Common Sensor Problems
