How To Fix Garage Door Sensor Lights

Garage door sensor lights are essential parts of a garage door system. They help prevent accidents by detecting objects or people in the path of a closing garage door. If the sensor lights malfunction, it can cause a lot of inconvenience and compromise the safety of your family and property.

Fortunately, fixing garage door sensor lights is not a difficult task. In this article, we will guide you through the process of fixing the issue and answer some frequently asked questions (FAQs) about garage door sensor lights.

Step-by-step guide to fix garage door sensor lights

Step 1: Check the alignment

Misalignment is one of the common reasons why garage door sensor lights stop functioning. You can easily determine if your garage door sensor lights are out of alignment by observing the sensor’s LED lights. If the LED lights are flashing, it means the sensors are not aligned correctly.

To fix misalignment, start by inspecting the sensors’ positions. Ensure that they are facing each other directly and lined up perfectly. If one of the sensors is tilted, remove it and reposition it until it is facing the other directly. It would help if you also checked whether there are any obstructions, such as dirt or cobwebs, that may block the sensor’s line of sight.

Step 2: Clean the sensors

Garage door sensor lights can accumulate dirt, dust, and other debris over time, which can prevent them from working correctly. If you have a dirty sensor, use a soft, dry cloth to wipe the lens gently. If the dirt is stubborn, use a mild detergent solution to clean the sensors.

It is crucial to avoid using harsh cleaning agents or abrasive materials such as sandpaper or steel wool, as they can scratch the sensor lens and cause permanent damage.

Step 3: Inspect the wires

Faulty or damaged wires can cause your garage door sensor lights to malfunction. They can be affected by pests, weather elements, or accidental damage. If you suspect that the wires are causing the issue, start by visually inspecting them for any visible signs of damage.

If you locate any damaged wires, fix them by splicing them with a new piece of wire and covering them with electrical tape. However, if the wires are too degraded, it is best to replace them altogether.

Step 4: Reset the sensors

If none of the above methods worked, you may need to reset the garage door sensors. You will need to disconnect the sensors from the power source, wait for a few seconds, and then reconnect them. The sensors will reboot, and the issues may be resolved.
