Garage door sensors are an essential component of modern garage door systems, designed to ensure the safety of your family and property. These sensors, often called “photo eyes,” create an invisible beam across the door’s path, preventing the door from closing if something or someone is in the way. However, like any other mechanical or electronic device, garage door sensors can malfunction, leading to frustrating and potentially dangerous situations.
If your garage door sensors are not working, don’t panic. This article will guide you through identifying and resolving the most common problems associated with malfunctioning garage door sensors. By following these steps, you can restore the proper functioning of your garage door system, ensuring a safe and convenient operation.
How garage door sensors work.
Garage door sensors are typically mounted inside the garage door frame, near the floor level, and face each other across the door’s opening. One sensor acts as a transmitter, emitting an invisible infrared beam, while the other functions as a receiver, detecting the beam. When an object or person interrupts the beam, the sensors send a signal to the garage door opener, preventing the door from closing and potentially causing harm.
These sensors are a crucial safety feature, as they help prevent accidents that could result in injury or property damage. They are designed to detect even small objects, such as a child or pet, ensuring that the door does not close on them.
Common issues with garage door sensors not working
Despite their importance, garage door sensors can encounter various issues that prevent them from functioning correctly. Some common problems include:
- Misalignment: If the sensors are not properly aligned, the infrared beam may not be detected, causing the door to malfunction.
- Obstructions: Dirt, debris, or objects blocking the sensors can interfere with the beam, preventing it from being detected.
- Power issues: If the sensors do not receive adequate power, they may not function correctly or fail to operate altogether.
- Wiring problems: Damaged or loose wiring connections can disrupt the communication between the sensors and the garage door opener.
- Environmental factors: Extreme temperatures, humidity, or sunlight can affect the sensors’ performance.
Identifying the root cause of the problem is crucial for resolving the issue effectively.
Troubleshooting steps for garage door sensors not working
If you’re experiencing issues with your garage door sensors not working, follow these troubleshooting steps to diagnose and resolve the problem:
Checking the power source for garage door sensors
- Inspect the power source: Check the wiring connections and the power supply to ensure that the sensors are receiving power. Look for loose or damaged wires and ensure that the power source is functioning correctly.
- Replace batteries (if applicable): If your garage door sensors are battery-operated, replace the batteries with fresh ones. Weak or dead batteries can cause the sensors to malfunction or fail to operate.
- Check for power outages: If the power goes out, your garage door sensors may not function properly. Wait for the power to be restored, and then test the sensors again.
Cleaning and adjusting the sensors
- Clean the sensor lenses: Over time, dirt, dust, or debris can accumulate on the sensor lenses, obstructing the infrared beam. Use a soft, dry cloth or a compressed air duster to clean the lenses gently.
- Adjust the sensor alignment: If the sensors are misaligned, they may not be able to detect the infrared beam correctly. Carefully adjust the sensor position by loosening the mounting brackets and realigning the sensors until they face each other directly.
- Check for obstructions: Inspect the area around the sensors for any objects blocking the infrared beam. Remove any obstacles, such as boxes, toys, or furniture, to ensure a clear path for the beam.
Testing the garage door sensors
- Perform a safety test: Most garage door openers have a built-in safety test feature that allows you to check the sensors’ functionality. Follow the manufacturer’s instructions to initiate the safety test and observe the sensor’s response.
- Use a sensor tester: If available, you can use a dedicated sensor tester tool to verify the proper operation of the sensors. These tools simulate an obstruction and can help identify any issues with the sensor’s detection capabilities.
- Swap sensor positions: Sometimes, one of the sensors may be faulty. Try swapping the positions of the transmitter and receiver sensors to determine if the issue lies with a specific sensor.
Replacing faulty sensors
If the troubleshooting steps above do not resolve the issue, one or both sensors may be defective and must be replaced. Here’s what you can do:
- Consult the manufacturer’s manual: The garage door opener’s manual provides instructions on how to replace the sensors properly. This will ensure that you follow the correct procedures and order the right replacement parts.
- Purchase new sensors: Obtain replacement sensors compatible with your garage door opener model. You may need to purchase them directly from the manufacturer or an authorized dealer.
- Install the new sensors: Follow the manufacturer’s instructions carefully to install the new sensors correctly. Proper alignment and wiring connections are crucial for the sensors to function properly.
Professional help for resolving garage door sensor issues

FAQs
Why would garage door sensors stop working?
Garage door sensors can stop working due to misalignment, dirt or debris blocking the sensors, or wiring issues. Additionally, malfunctioning sensors could be caused by wear and tear or a power supply problem.
How to reset sensor on garage door?
First, reset the garage door sensor, ensure the sensors are aligned, and then disconnect and reconnect the power to the garage door opener. Often, pressing the reset button on the motor unit will also reset the sensors.
How do I know if my garage door sensors are bad?
You can tell if your garage door sensors are wrong if the door doesn’t close properly, the sensor lights are not lit, or the door reverses unexpectedly. Additionally, if the sensors are aligned and clean but still malfunctioning, they may need to be replaced.
Should both garage sensors be green?
When aligned and functioning correctly, both garage door sensors should typically show a green light. A red or blinking light on either sensor usually indicates a problem that needs addressing.
Why is there no power to my garage door sensors?
Your garage door sensors may not be powered due to a tripped circuit breaker, a blown fuse, or a disconnected or damaged power cable. Check these components to restore power to the sensors.
