When most homeowners encounter garage door problems, they typically experience issues with the opener motor, cables, or remote. However, one less obvious, but equally frustrating problem, is garage door opener sensor misalignment. This issue can cause the door to malfunction in ways that are subtle, intermittent, and often hard to detect. Let’s explore this uncommon issue, how to fix it, and ways to avoid it in the future. For Arlington residents, we’ll also provide insights on how to find a garage door expert and obtain free estimates from Best Garage Doors Inc.
Understanding Garage Door Sensor Misalignment
Garage door openers are equipped with safety sensors located on either side of the door. These sensors send infrared beams to detect obstacles in the door’s path, preventing the door from closing when something is in the way. When functioning correctly, the sensors should communicate seamlessly, ensuring the door closes fully without obstruction.
However, sensor misalignment can cause the door to malfunction in a more subtle way, where the sensors are still “on” but not perfectly aligned. This results in intermittent issues, such as:
- The door closing halfway and then reversing.
- The door working intermittently – it may open and close, but it doesn’t work consistently.
- The door reversing after it starts closing, thinking it has encountered an obstruction.
Even though the sensors may appear functional (e.g., the lights on the sensors might still be on), the alignment could be just slightly off, preventing the door from completing its cycle.
Why Misalignment Happens
Sensor misalignment can occur for various reasons, including:
- Vibrations or external forces: Over time, the sensors may shift slightly due to vibrations from the door’s movement or from external forces like wind or accidental bumps.
- Improper installation: If the sensors were not aligned properly during installation, the misalignment may become noticeable after extended use.
- Physical damage: If the sensors are knocked or bumped, they may become misaligned without visible damage, affecting their functionality.
How to Fix Garage Door Opener Sensor Misalignment
If you’re dealing with a misaligned sensor, don’t worry—it’s usually a simple fix. Here’s how you can address it:
- Inspect the Sensors:
- First, check the sensors on either side of the door. They should be mounted at the same height, typically around 6 inches above the ground, and aligned directly facing each other.
- Look for any visible obstructions, dirt, or debris that could block the sensor’s signal.
- Adjust the Sensors:
- If you notice that the sensors are misaligned, gently adjust them so they’re facing directly at each other. Most sensors are mounted on brackets that can be adjusted by hand.
- You can use a level to ensure the sensors are vertically aligned.
- Clean the Sensors:
- Sometimes, misalignment can be caused by dirt or spider webs obstructing the sensor’s signal. Clean the lens of both sensors with a soft cloth.
- Check the Sensor Light:
- Once adjusted, verify that the sensor lights are functioning correctly. On most models, when aligned, the light will stay on continuously (usually green). If the light blinks or turns off, there may still be an alignment issue.
- Test the Door:
- After making adjustments, test the door by using the opener to see if it closes fully without reversing. If the door operates smoothly, the issue is resolved.
How to Avoid Sensor Misalignment in the Future
While it’s relatively easy to realign garage door sensors, preventing future misalignment can save you time and frustration. Here are some tips:
- Check alignment regularly: Every few months, inspect the sensors to ensure they are still aligned and functioning properly.
- Be cautious of impacts: Avoid hitting the sensors when parking your vehicle, or consider installing bumper guards around the sensors to prevent accidental bumps.
- Install the sensors at an optimal height: Ensure the sensors are mounted securely and at the proper height, away from high-traffic areas where they may be disturbed.
- Professional installation and maintenance: When installing or replacing sensors, hire a professional to ensure they are set up correctly from the start.
