7 Steps to Follow on How to Align Garage Door Sensors Liftmaster

Step 1: Check the Sensor Lights.

Before attempting to align the sensors, you’ll need to ensure they’re connected and working properly. To do this, look for a small LED light near each sensor, indicating whether each one is connected and functioning correctly.

If one of the lights isn’t lit up, you’ll need to reset it by unplugging the power source, waiting 10 seconds, and then plugging it back in again.

Step 2: Adjust the Sensors.

Once you’ve checked that both sensors are working properly, it’s time to adjust them to align. Start by loosening the screws on one of the sensors and then moving it until its light lines up with the other sensor’s light (the lights should be no more than 6 inches apart). Tighten the screws again once you have both lights aligned correctly.

Step 3: Test It Out.

Once both sensors are aligned properly, try out your garage door opener—it should now open and close as normal! If not, go back and double-check that both sensor lights are lined up correctly before troubleshooting further.

Step 4: Check the Sensor Height.

If your garage door opener is still not functioning properly, it could be because one of the sensors is too low or too high. In this case, you’ll need to adjust how high or how low each sensor is mounted on the wall in order to get them at an equal height.

Step 5: Make Sure They Point at Each Other.

Another potential cause of misalignment is that the sensors aren’t pointing in the same direction. To fix this issue, loosen the screws on each sensor and then adjust them so that they are both pointed directly toward each other (i.e., their lights should face one another).

They Are Both Pointed Directly Toward

Step 6: Check the Sensor Placement.

If you’re still having problems, check how far apart each sensor is mounted from one another. The optimal distance between them should be no more than six inches—if they are too far away from each other, then this could explain why your door isn’t opening and closing correctly.

Step 7: Make Sure the Sensors are Clean.

Finally, ensure that both sensors are clean and free of dirt or debris. This can cause misalignment, so be sure to thoroughly wipe each one down with a damp cloth before you try using your garage door again.

That’s it! You’ve now learned how to align garage door sensors Liftmaster. With any luck, following these steps should help you get your garage doors up and running in no time! Good luck!
