Garage door sensors are essential components that ensure the safe and smooth operation of residential garage doors. However, like other garage door components, these sensors are not impervious to malfunction. One common concern is the interference caused by sunlight.
But can sunlight interfere with garage door sensors? Absolutely! Sunlight can interfere with garage door sensors, leading to malfunction or unreliable operation. In this article, we explore the underlying reasons behind sunlight interference.
We also look at how it can affect garage door sensors and provide effective solutions to tackle this challenge head-on.
Can Sunlight Interfere with Garage Door Sensors?
Direct sunlight can interfere with garage door sensors’ signals. When the rays from the sun radiate into the safety sensors, it disrupts their infrared light. This leads to false detections and prevents the sensors from functioning correctly.
A good example is when your garage door faces east or west, direct sunlight streams into the garage during sunrise or sunset and falls directly on the sensors. This creates a glare that prevents the sensors from correctly receiving signals, leaving your garage door’s safety feature dormant.

Problems Faced by Homeowners When Sunlight Interferes With Garage Door Sensors
Some homeowners may consider bypassing garage door sensors as a short-term fix. However, this approach can introduce additional complications. Here are some of the main problems they can face:
- Security vulnerabilities: When the garage door fails to close properly due to sunlight interference, it exposes the garage and its contents to potential theft or unauthorized access. This can be particularly concerning if valuable items or vehicles are stored in the garage. You may need to take extra precautions to secure your property, leading to added stress and inconvenience.
- Loss of convenience: One of the primary benefits of an automated garage door system is its convenience. Sunlight interference disrupts this convenience since you’ll be required to take additional steps to close the garage door manually. This can be frustrating and impact the overall user experience.
- Safety concerns: If the sunlight overrides the garage door sensors and prevents the door from closing when there are obstructions, it poses a significant safety risk. For example, a person or a child could unknowingly walk into the path of the closing door, leading to potential injuries. Similarly, the door and vehicles may get damaged if objects are left in the doorway since they might not be detected.
- Increased energy consumption: An open garage door allows heat or cold air to enter the garage, affecting your home’s overall energy efficiency. This leads to higher energy bills and unnecessary energy waste since the HVAC system must work harder to compensate for the temperature fluctuations.
Why Is The Sun Not Allowing My Garage Door To Close?
Most residential garage door sensors depend on photo-eye and infrared technology for efficient and effective operation. They consist of a transmitter and receiver placed on opposite sides of the garage door, emitting an infrared beam between them. When an object breaks the beam, it signals the garage door opener to stop or reverse the door’s movement.
That said, the following are the reasons why garage door sensors may be affected by sunlight interference:
The angle of the sensor
Suppose the sensor directly faces the sun, especially during specific times of the day when the sun is low on the horizon. In that case, it increases the likelihood of direct sunlight falling on the sensors. This direct exposure can overpower the sensors’ emitted beam and interfere with their ability to detect objects or obstructions accurately.
Energy from the sunlight
Sunlight, with its intense infrared light, can surpass the sensor’s own emitted beam in strength. When it infiltrates the sensor’s pathway, it can either obstruct the sensor’s beam or generate misleading signals by activating the sensor’s receivers. This overpowering sunlight effectively “blinds” the sensor’s lens, significantly diminishing its operational efficacy by compromising its ability to accurately detect obstacles or changes in the environment.
Heat from sunlight
Sunlight also generates heat that affects the sensors’ performance. This excessive heat causes the sensors to overheat, leading to temporary malfunction or unresponsiveness.
Other components
Materials like reflectors or metal surfaces near the sensors can also reflect sunlight and redirect it toward the sensors, intensifying the interference.
How to Identify Sunlight Interference with Garage Door Sensors
Identifying sunlight interference with garage door sensors is crucial to address potential issues and ensure proper functionality. Here are some of the signs and symptoms to look out for:
False activations
If your garage door opens or reverses without apparent obstructions, especially when sunlight is intense or directly shines on the sensors, it may indicate sunlight interference.
Inconsistent sensor performance
Do your garage door sensors work fine under normal lighting conditions but experience malfunctions or false detections when exposed to direct sunlight? If so, this is a clear indication of sunlight interference. This is due to the overpowering effect of sunlight, resulting in the unreliable operation of the garage door system.
Delayed or slow response
Sunlight interference can also cause a delay or slow response in the garage door operation. The sensors may struggle to accurately detect the opening or closing commands due to the presence of sunlight, resulting in a noticeable delay in the door’s movement.
Visual observation
Conduct a visual inspection of your garage sensors and their surroundings. If you notice reflective surfaces near the sensors that could amplify or redirect sunlight toward them, it strongly indicates potential sunlight interference.

How Do I Stop My Garage Door Sensor From Interfering With The Sun?
You can employ various methods to stop your garage door sensor from interfering with the sun. However, DIY approaches and seeking professional assistance are the most common ways. Here is how you can apply both measures:
DIY Solutions
Several DIY solutions allow you to address this issue without professional assistance. They include the following:
1. Adjust the Sensor Position
Reposition the sensors away from direct sunlight to reduce the chances of interference. You can experiment with different angles and heights till you find the optimal position that maximizes their effectiveness and minimizes the impact of sunlight interference. We highly recommend positioning the sensors inside the garage, facing each other, and mounted on the vertical tracks or walls.
2. Create a Shade
You can create a shade for the sensors using simple objects such as cardboard or a toilet paper tube. By placing the shade strategically, you can block the direct sunlight from falling on the sensors, reducing the chances of interference. Here’s a step-by-step guide on how to make a shade using each of these materials:
Using a Cardboard
- Measure the length and width of the sensor lens. Use these measurements to cut a piece of cardboard covering the lens adequately.
- Fold the cardboard piece in half lengthwise to create a V-shape. This shape will help shield the sensor lens from direct sunlight while allowing the emitted beam to pass through.
- Place the folded cardboard shade over the sensor, ensuring it covers the lens completely. Use tape or adhesive to secure the shade in place. Ensure it is firmly attached and does not obstruct the sensor’s operation.
Using a Toilet Paper Tube
- Begin by measuring the length of the sensor lens and cut a section from a toilet paper tube that matches this length.
- Carefully split the toilet paper tube lengthwise to create a semi-circular shape.
- Place the split toilet paper tube over the sensor lens, aligning it to cover the sensors. The split portion will act as a shade, blocking direct sunlight while allowing the sensor to function properly.
- Use tape or adhesive to secure the split tube shade in place, ensuring it remains fixed and does not obstruct the sensor’s operation.
3. Upgrade Your Sensors
Consider upgrading your garage door sensors to models designed to resist sunlight interference. A good example is the Safe-T-Beam® Garage Door Opener Safety Sensors from Genie. This model comes with built-in sunlight filters or advanced features that mitigate the impact of sunlight.
