Photocells on residential garage doors

Doors manufactured in the United States and Canada within the last five years include photocells to prevent tntrapment. This safety system is at the botom of the door usually between 4"-8" above the floor. If the door senses movement or a blocking object while closing, it will open again. What is important to know:

• Photocells must be properly aligned to work
• Lenses must be clean
• Lenses can be damaged by exposure to sunlight
  

To test this garage door security system in your home, from the inside of your home, try closing the door and then roll a ball that is bigger than height of the photocell. If it does not make the door to open again or stop from closing, you need to contact a professional to inspect it. At All About Doors, we are committed to your safety and will perform an inspection of your system for proper performance.
