Garage door sensors In Toronto

Garage door sensors are safety devices that prevent the door from closing on people, pets or objects in the doorway. The sensors are located above the floor at each side of the door opening and generate a low-voltage beam that completes the electrical circuit when the door is activated. Garage doors may display a variety of symptoms when the sensors need attention. In most cases you can troubleshoot the system and correct the cause of problems. Before you begin, make sure the electrical cord from the opener is plugged in and the electrical circuit is active.
