Garage Door Sensors
Garage Door Sensor Issues
Garage doors feature numerous moving parts and can be extremely heavy, with potential for causing significant damage or injury to pets, family members, and property. Due to this potential, all garage doors manufactured in the U.S. after 1993 are required to have a safety reversing system, which will detect any obstacles between the garage door and the ground, and reverse or force the garage door to stay open.
What Are Garage Door Sensors?
These garage door safety sensors are typically mounted 4-6 inches from the ground along the garage door track. The sensors are connected by an invisible infrared beam and are programmed to reverse the garage door if an object, person, or animal gets between the two sensors.
Malfunctioning garage door sensors can cause the garage door to remain open or reopen immediately after closing. Most garage door sensors have a light that is programmed to blink to indicate a problem.

Common Problems With Garage Door Sensors
Dirt or dust on the sensors
Misalignment due to jarring or movement during normal use
In rare cases, the lens can become damaged and need to be replaced
How to Fix Garage Door Sensors
1
Check for any obstructions in the doorway that may be interrupting the connection between the sensors.
2
Thoroughly clean both lenses. We recommend using a cotton swab and rubbing alcohol clean the lenses.
3
Inspect the wires that lead to the sensors for any damage or fraying.
4
Check the alignment of the sensors. Ensure that both amber and green lights are on, solid, and not flickering. If adjustment is needed, tighten the brackets attached to the sensors.
