What Are Safety Sensors and Why Do They Matter?
Safety sensors, sometimes called photo-eye sensors, are small devices installed on both sides of the garage door near the floor. They project an invisible infrared beam across the door’s opening.
If something interrupts that beam—like a pet, child, or object—the garage door will stop closing and automatically reverse. This system prevents serious accidents, injuries, and property damage.
Chamberlain safety sensors are:
- Required by law – Since 1993, all garage door openers in the U.S. must include safety sensors.
- Child- and pet-safe – Protect loved ones from accidents.
- Reliable – Keep your garage door functioning as intended.
Signs You Need Chamberlain Garage Door Opener Replacement Safety Sensors 2 Pack
Over time, safety sensors may become misaligned, dirty, or damaged. Common signs that you may need replacements include:
- Flashing lights on the garage door opener indicating sensor issues.
- Garage door won’t close unless you press and hold the wall control button.
- Visible damage such as cracked housings or frayed wires.
- Frequent false triggers even when the doorway is clear.
If cleaning and realigning the sensors doesn’t fix the issue, it’s time to consider the Chamberlain Garage Door Opener Replacement Safety Sensors 2 Pack.
