What Are Garage Door Safety Sensors and How Do They Work?
1. What Are Garage Door Safety Sensors and How Do They Work?
Garage door safety sensors, also known as photoelectric sensors or eyes, are the infrared sensors on each side of your garage door opening. They detect obstructions to prevent your garage door from closing on people, pets or objects.
The sensors emit and detect infrared light beams between each other. If the light beam is broken by an obstruction, the sensor detects it and instantly reverses or stops the garage door to prevent injury or damage. For your garage door to close properly, the sensors must be able to see each other and maintain the infrared light beam connection.
- Infrared light is invisible to the human eye but can be detected by the sensor
- The light beam is emitted in a cone shape, so alignment and lack of obstruction are important
- Sensors require a power source, typically batteries or hardwiring to your garage door opener, to function
If your garage door is behaving erratically or won’t close, it’s likely an issue with your safety sensors. But don’t worry, troubleshooting problems with your garage door safety sensors is often an easy DIY task. The most common issues are:
- Misalignment: The sensors are not facing each other directly, so the light beam is obstructed. Re-align the sensors to face each other.
- Dirty lenses: Built up dirt, dust or cobwebs on the sensor lenses block the infrared light beam. Clean the lenses with a soft, damp cloth.
- Obstruction: An object like a toy, debris or garden hose is blocking the light beam. Remove any obstructions from the path of the beam.
- Loss of power: If the sensors are hardwired, check for any damage to the wiring. For battery-powered sensors, replace the batteries.
- Malfunction: As a last resort, the sensors themselves could be damaged or defective and need replacement. But first rule out other potential issues before replacing the sensors.

Common Signs Your Garage Door Sensors Need Repair
If your garage door isn’t closing properly, the safety sensors are a good place to start. These sensors, located at the bottom of the garage door tracks, detect if there are any obstacles in the way of the closing door. If anything is detected, the door will immediately stop and reverse direction to avoid causing damage or injury.
Common Signs Your Garage Door Sensors Need Repair
One of the most obvious signs that your safety sensors aren’t working is if your garage door won’t close all the way. If the sensors detect an obstacle, the door will stop and reverse to the open position. Check to make sure there is nothing blocking the sensors and test to see if the door will close. If not, the sensors likely need adjustment or replacement.
Another sign is if your garage door opens but won’t close. Again, this could indicate the sensors have detected an obstacle, even if there doesn’t appear to be anything in the way. The sensors may be misaligned or damaged, preventing the garage door from closing.
You may also notice the garage door opening and closing on its own. This could indicate interference or a short in the sensor wiring, causing the door to operate as if an obstacle was detected. It’s best to unplug the garage door opener in this situation to prevent damage or injury.
Lastly, if the sensor lights on your garage door opener aren’t coming on, it likely indicates a problem with the sensors. The lights should illuminate when the sensors detect an obstacle. If the lights don’t come on at all, the sensors may need to be repaired or replaced.
If you notice any of these signs, it’s best to contact a professional garage door company to inspect and repair or replace your safety sensors. Faulty or malfunctioning sensors can be extremely dangerous, so don’t delay in getting them serviced. Your garage door is a heavy piece of equipment and safety should be a top priority!
Step-by-Step Guide to Troubleshooting Sensor Issues
If your garage door isn’t closing properly, the issue could be with the safety sensors. These sensors detect if anything is obstructing the door so it won’t close and cause damage or injury. Troubleshooting problems with your garage door safety sensors is often an easy DIY task. Here’s a step-by-step guide to get your garage door closing securely again.
Check the sensors
The first thing to check is if the sensors themselves seem damaged or misaligned. Look for any dents, scratches or debris on the lenses of the sensors. Also check that the sensors are pointing directly at each other, aligned and at the same height on each side of the door. If they’re crooked or at different heights, loosen the mounting bracket and adjust as needed, then tighten in place.
Inspect the wiring
If the sensors appear intact, the issue could be with the wiring. Trace the wires from the sensors to the garage door opener unit. Look for any visible damage to the wires or points where the wiring is loose, frayed or exposed. Tighten any loose connections or splice and re-insulate any exposed or damaged wiring.
Test the sensors
Once the sensors and wiring all look to be in good working order, it’s time to test the system. Have someone stand in the doorway to block one sensor while you try closing the garage door with the remote or wall switch. If the door starts to close, then stops and reverses upon detecting the obstacle, the sensors are working properly. If not, proceed to the next step.
Replace the batteries
If the sensors still don’t seem to be detecting obstacles, the issue could simply be dead batteries. Most garage door sensors run on standard 9V batteries. Pop out the old batteries from both sensors and replace them with a matched set of fresh 9V batteries. Once the new batteries are installed, re-test the system to ensure the door is now reversing properly.
Call a professional
If new batteries don’t solve the problem, there may be an issue with the sensor circuit board or the garage door opener unit itself. At this point, it’s best to contact a professional garage door technician to inspect, test and repair or replace components as needed to get your garage door safety system working properly again. They can also perform regular maintenance to help prevent future issues.

When to Call a Professional for Garage Door Sensor Replacement
If your garage door safety sensors are acting up, it’s important to troubleshoot the issue to determine if you can fix it yourself or if it’s time to call in a professional. Safety sensors, also known as photoelectric sensors, are the electronic eyes that ensure your garage door opens and closes properly. They detect when something is blocking the door so it won’t crush whatever’s in the way.
Do the sensors need to be realigned?
The most common problem with garage door sensors is misalignment. Over time, the sensors can get bumped out of position, preventing them from detecting each other properly. To realign the sensors:
- Locate the receiving sensor (with the red LED light) and the sending sensor (with the green LED light). The red sensor should point to the green sensor.
- Loosen the wingnut or mounting screw that holds each sensor in place.
- Make sure the sensors point directly at each other and are lined up vertically. They should be no more than 6 inches off the floor.
- Tighten the wingnuts to secure the sensors in the proper position.
- Test your garage door to ensure it’s working properly. The LED lights on both sensors should now be solid.
If realigning the sensors doesn’t fix the issue, it’s likely time to call a professional garage door company to inspect and potentially replace the sensors.
When to call for service
It’s best to call a professional garage door company like Moja Garage Doors when:
- The sensors are severely damaged or not working at all. Replacement safety sensors need to be installed properly to ensure safety and functionality.
- The garage door still won’t close after you’ve tried realigning the sensors. There could be an issue with the door itself or the opener.
- You’ve checked the obvious solutions but can’t determine the cause of the problem. Professionals have the experience to troubleshoot and fix issues quickly.
- You want to avoid potential injury or property damage. Malfunctioning garage doors and openers can be dangerous if not addressed promptly by a professional.
