Garage door safety sensors are critical safety devices that prevent door closing if objects, people, or animals are in the door's path, and our certified technicians at Ripon Garage Door Repair Services ensure these vital systems function properly to protect your family. Modern garage doors are required by federal safety codes to include photo-eye safety sensors (also called safety edge sensors or motion sensors) that detect obstacles in the door's path and trigger the reverse mechanism to stop and raise the door. When safety sensors malfunction, fail to detect obstacles, or become misaligned, they create serious hazard risks of door collision injuries, crushing, or entrapment. Our technicians test sensor functionality, clean sensor lenses of dust and debris that impair detection capability, realign sensors if mispositioned, and replace defective sensors with quality replacement units. We also test reverse mechanisms to confirm proper door reversal when sensors detect obstacles.
