How to Test and Adjust Your Garage Door Sensors for Safety

At Rightly Garage Doors, we take your safety seriously. As a trusted provider of garage door services in Westcliffe, CO, we know how crucial it is to have properly functioning garage door sensors. These sensors prevent accidents by detecting obstacles in the door’s path and stopping it from closing if something is in the way. Over time, sensors can become misaligned or dirty, leading to potential safety hazards. In this guide, we’ll walk you through the steps to test and adjust your garage door sensors to ensure they function correctly.

Why Garage Door Sensor Safety Matters

Garage door sensors are vital to your garage door system. They use infrared beams to detect objects in the door’s path and prevent it from closing if an obstruction is detected. According to our friends at All American Doors, if these sensors are not functioning properly, your garage door may not stop when an obstruction is present, posing a danger to people, pets, and vehicles. Regular maintenance and testing can help avoid potential injuries and costly repairs. 

Tools You’ll Need

Before you begin, gather the following tools to test and adjust your garage door sensors:

• A soft cloth
• A level
• A screwdriver (if adjustments are needed)
• Replacement sensors (if necessary)

Step 1: Inspect the Sensors

Begin by visually inspecting your garage door sensors. They are typically located on either side of the garage door, about six inches above the ground. Look for signs of dirt, dust, or debris blocking the infrared beam. Use a soft cloth to clean the sensor lenses carefully.

Also, check for any physical damage to the sensors or wiring. If you notice any frayed wires or cracks in the sensor casing, it may be time to replace them.

Step 2: Test the Sensor Alignment

To test whether your garage door sensors are aligned properly, follow these steps:

1. Close your garage door and observe the sensor lights. Most garage door sensors have indicator lights that show whether they are aligned correctly.
2. If the lights are solid, your sensors are likely aligned correctly. If they are blinking or off, misalignment may be the issue.
3. To confirm misalignment, try closing the garage door using the remote control. The sensors need adjustment if the door does not close and reverses instead.

Step 3: Adjust the Sensors

If your sensors are misaligned, follow these steps to adjust them:

1. Loosen the mounting brackets using a screwdriver.
2. Gently adjust the sensors so that they are facing each other directly.
3. Use a level to ensure they are perfectly aligned.
4. Tighten the brackets once the alignment is correct.
5. Check the indicator lights again to verify proper alignment.

If the lights remain solid, your sensors should now be properly aligned.

Step 4: Test the Safety System

After adjusting the sensors, it’s important to test the entire safety system to ensure it’s working as expected. Follow these steps:

1. Open the garage door completely.
2. Place an object, such as a cardboard box, in the path of the sensors.
3. Press the garage door remote to close the door.
4. The door should stop and reverse immediately upon detecting the object.

If the door does not reverse, double-check the alignment and clean the sensors again. If problems persist, consider contacting Rightly Garage Doors for professional assistance.

Step 5: Regular Maintenance Tips

To keep your garage door sensors in optimal working condition, consider the following maintenance tips:

• Clean the sensor lenses regularly to prevent dirt buildup.
• Check sensor alignment periodically, especially after severe weather.
• Inspect the wiring for any signs of wear and tear.
• Test the safety reversal feature every few months to ensure reliable operation.
