How to Fix A Yellow Light on Garage Door Sensor

A yellow light on a garage door sensor is one of the most common problems our experts receive calls about here at Affordable Garage Door Fix. Though a yellow light might not seem like a big inconvenience, it could be a sign of a larger problem.  Fortunately, in most cases, it is easy to fix a yellow light on a garage door sensor. In this blog post, we’ll explain what is causing a yellow light on a garage door sensor and how you can fix it. 

What Does A Yellow Light on a Garage Door Sensor Mean?

The most common cause of a yellow light is misalignment, which can happen for a variety of reasons—weather, bumping the sensor, etc. Misalignment can be a safety hazard, as the misaligned sensors may cause the door to not close properly or unexpectedly reverse. Sensors can also malfunction or become blocked by dirt and other particles, causing the same yellow warning light. Regardless of the cause, it’s important to address the yellow light as soon as possible to avoid any potential safety concerns and ensure your garage door functions properly when entering or leaving. Follow the steps outlined below to get rid of the yellow light and ensure your garage stays functional. 

Clean The Sensor Lens

The sensor lenses are small glass sheets that accumulate dust and debris, so the first thing you should do is gently clean the sensor lens with a microfiber cloth. Using a microfiber cloth will ensure that any dirt that has accumulated on the surface will be removed while protecting the lens from accidental scratches. If dirt was the issue, you should notice the light immediately turn green. If not, keep reading to pinpoint other issues with sensor misalignments or blockages. 

How to Fix Sensor Misalignment

To realign your sensors, you’ll need to turn off the power and loosen the screws housing the sensors so that they can be adjusted freely in their bracket. After the screws are loosened, tie a piece of string across the mounting bracket and stretch it across to the opposite side of the garage, using the string as a guide for aligning the sensors. With this process, you can easily tell if your sensors are crooked and adjust them accordingly, ensuring that your garage door operates smoothly and safely. Be sure to re-tighten the screws before wrapping up or moving on.

Remove Blockage to Fix A Yellow Sensor Light

Garage door sensor still blinking yellow? Believe it or not, a blockage surrounding the sensor could be the cause of the problem. To ensure the sensors work efficiently, they need to send a “beam” of light, and as a safety precaution, they won’t work if they are obstructed by anything like bikes, sports equipment, or other items. Check out the surroundings of the sensor, remove any obstructions, and relocate them to prevent future blockages.
