Can I bypass safety sensors to close my door in an emergency?

Why Does My Garage Door Close and Then Immediately Reopen?

Quick Answer Summary

When a garage door closes and immediately reverses, the safety reversing system is being triggered. The two primary causes are misaligned photoelectric safety sensors (often indicated by 10 flashing opener lights) or incorrect down-travel limit settings that make the opener think the floor is an obstruction.

Safe Homeowner Checks

•Check the two small sensor eyes located 6 inches above the floor on each track. Clean the lenses with a dry cloth.
•Verify that both sensor LEDs are solid (not flickering). If one is blinking, gently adjust its bracket by hand until it points directly at the companion sensor.
•Check the threshold floor area for objects like broomsticks, toys, leaves, or packed ice.

When Professional Help Is Required

•Sensors are illuminated steadily, but the door still reverses consistently.
•Adjusting down-force screws does not stop the door from bouncing off the concrete.
•The logic circuit board flashes internal diagnostic fault codes.

Understanding Federal Safety Sensor Requirements

Under federal UL 325 safety standards, all garage door openers manufactured since 1993 must include a non-contact safety reversing mechanism. If the infrared beam is broken or the sensor heads vibrate out of alignment during door travel, the opener automatically reverses to prevent crushing people, pets, or property.

Texas Sun Glare Interference

In Texas, bright low-angle sunlight hitting the receiving sensor lens during certain morning or afternoon hours can blind the optical sensor. Shading the receiving sensor or reversing the mounting positions solves this seasonal issue.

Frequently Asked Questions

You should never permanently bypass safety sensors as this creates a severe life safety hazard. However, on most modern openers, pressing and continuously holding the interior wall push-button will override the sensors and force the door closed.
