    aligning garage door sensors

    A garage door sensor is an essential safety feature, but it can become misaligned over time. Ensuring these sensors are correctly aligned is crucial for the safety and function of your garage door. In this post, we’ll delve into the steps to align your garage door sensors and answer some frequently asked questions on the topic.

    Step-by-Step Guide to Aligning Garage Door Sensors

    1. Safety First: Before starting, unplug the garage door opener to ensure your safety.
    2. Locate the Sensors: Typically, sensors are installed on both sides of the garage door, near the floor.
    3. Loosen the Sensors: Gently loosen the screws or wing nuts holding the sensor in place. This allows you to adjust its position without entirely removing it.
    4. Adjust and Align: Line up the two sensors. Most sensors have indicator lights. When aligned, both lights should remain steady. If blinking, they’re not correctly aligned.
    5. Tighten the Sensors: Once aligned, tighten the screws or wing nuts without moving the sensors out of alignment.
    6. Test: Plug the garage door opener back in and test the door. If the door reverses while closing, further adjustments might be necessary.
    7. Clean the Sensors: Sometimes, the problem can be due to dirty sensors. Learn how to clean garage door sensors here.
    8. Inspect for Damage: If aligning doesn’t resolve the issue, inspect the sensors for visible damage. Damaged sensors may need replacement.
