Your garage door’s safety sensors play a crucial role in keeping your home and family safe. These sensors use infrared beams to detect objects in the path of the door and prevent it from closing if something is in the way. But did you know that even something as simple as sunlight can cause them to malfunction?
At Integrity Garage Doors in Asheville, NC, we’ve seen many cases where sunlight was the unexpected culprit behind sensor issues. Here’s what you need to know — and what you can do to prevent it.
How Sunlight Affects Garage Door Sensors
Garage door sensors communicate using low-powered infrared light. When direct sunlight hits the sensors at just the right (or wrong) angle, it can flood the sensor with competing light. This interference can confuse the system, making it think there's an obstruction even when the path is clear.
Luckily, this problem is usually temporary — sunlight shifts as the day goes on. But in some cases, repeated exposure can cause lasting issues.
A Simple DIY Fix
If you suspect sun interference, a temporary fix could be placing a short tube (like a cut toilet paper roll) over the sensor to block excess sunlight. While not elegant, it can help identify the issue.
A more permanent and professional solution is to install sensor shields specifically designed to protect the sensors from direct sunlight while maintaining a clear infrared path. Our technicians at Integrity Garage Doors can help install these for you.
Other Common Sensor Problems
Sunlight isn’t the only thing that can affect your sensors. Dust, spider webs, and debris are just as likely to block the signal. We recommend gently wiping your sensors with a soft, dry cloth once a month. Keeping them clean ensures optimal function and reduces false readings.
Heat Can Cause Long-Term Damage
Prolonged exposure to direct sunlight doesn’t just cause temporary issues — it can overheat the sensors. Since these sensors often have convex lenses, the sunlight can focus heat onto the internal electronics, similar to how a magnifying glass can start a fire. This can lead to sensor failure over time and require replacement.
Don’t Disable the Sensors
While some garage door openers allow you to bypass the sensors, we strongly advise against it. Sensors are a critical safety feature. Garage doors are heavy and powerful — disabling safety sensors puts your family and property at risk. If you’re experiencing recurring issues, give us a call instead of turning them off.
