Signs Your Garage Door Sensor Needs Realignment
How can you tell if your garage door sensor needs realignment? Look out for the following signs:
- The garage door reverses after partially closing.
- The garage door won’t close at all.
- The garage door opener light blinks repeatedly.
- You hear clicking sounds from the garage door opener.
Tools Required for Realigning Garage Door Sensors
Before you begin, gather the necessary tools:
- Screwdriver

Step-by-Step Guide on How to Realign Garage Door Sensor
Step 1: Ensure Safety First
Before working on your garage door sensor, make sure to unplug the garage door opener to avoid any accidents. Safety should always be your top priority.
Step 2: Inspect the Sensors
Locate the sensors near the bottom of your garage door tracks. They are usually mounted on brackets. Inspect them for any visible damage or dirt. Clean the lenses with a clean cloth if necessary.
Step 3: Check the Alignment
Using a level, check if the sensors are aligned with each other. They should be pointing directly at each other. If they are misaligned, proceed to the next step.
Step 4: Adjust the Sensors
Loosen the screws or bolts holding the sensors in place. Gently adjust them until they are perfectly aligned. Use the level to ensure accuracy. Once aligned, tighten the screws or bolts.
Step 5: Test the Sensors
Plug in the garage door opener and test the sensors by closing the garage door. If it closes without any issues, the sensors are properly aligned. If not, repeat the alignment process.
Troubleshooting Common Problems
Sometimes, realigning the sensors might not solve the issue. Let’s explore some common problems and their solutions:
Problem 1: Obstructed Sensor Path
Ensure there are no objects blocking the sensor path. Even a small obstruction can interfere with the sensor’s functionality.
Problem 2: Wiring Issues
Inspect the sensor wiring for any loose or damaged connections. If needed, reconnect or replace the wires to ensure a proper connection.
Problem 3: Faulty Sensors
If the sensors are still not working correctly, they might be faulty. Consider replacing them with new, compatible sensors.
