Alright, let’s talk about aligning garage door sensors. You know, those little things sitting at the bottom of your garage door tracks that sometimes act up and stop your garage door from closing. Now, if you’re a New Yorker like me, you’ve probably had enough with gadgets giving you a hard time. But don’t worry, this fix is simple—like a Sunday stroll through Central Park.
If your garage door starts going back up instead of closing, chances are those sensors are misaligned. Lucky for you, I’ve got the step-by-step guide to get them working right again.
What Are Garage Door Sensors Anyway?
These sensors are like the unsung heroes of your garage door system. They send out an infrared beam from one side of the garage to the other. If something blocks that beam—like your dog or some random box— the door stops from crushing it. But when the sensors are misaligned, the door gets confused and won’t close even when there’s nothing in the way.
So, you need to realign them and trust me, it’s easier than finding decent pizza outside of New York.
Signs Your Garage Door Sensors Are Off
Before you jump into fixing anything, let’s make sure the problem really is the sensors. Here’s what you need to look out for:
- The door opens but won’t close
- You notice the garage door light blinking
- You have to hold down the wall button to close the door
- The door reverses immediately after you try to close it
If any of this sounds familiar, you’ve probably got a sensor issue on your hands.
What Tools You’ll Need
Nothing fancy here, just some everyday tools:
- Screwdriver
- A string (yes, you read that right)
- Level (to make sure things are straight)
- Cleaning cloth (sensors get dirty, go figure)
Step-by-Step: How to Align Garage Door Sensors
Now, here’s the fun part. Let’s walk through the steps to get those sensors working like they should.
1. Safety First—Kill the Power
Before you touch anything, disconnect the power to your garage door opener. You don’t need any accidents. Trip the fuse or just unplug the opener from the wall. Better safe than sorry, right?
2. Clean Those Sensors
Start by giving the sensors a good cleaning. A lot of times, dirt, cobwebs, or dust can interfere with the signal. Grab a soft, dry cloth and wipe them down. Check for debris too—garage floors collect all sorts of junk.
3. Loosen the Sensor Brackets
Grab that screwdriver and loosen the screws on the brackets holding the sensors in place. Don’t go crazy here, just loosen them enough so the sensors can move up and down. We don’t want them falling off.
4. Line Them Up with a String
Here’s where the string comes in. Tie it around the bracket of one sensor and stretch it across to the other sensor on the opposite side. This will help you align them at the same height. Don’t have a string? Use your eyes, but the string makes it easier and more accurate.
5. Use a Level
Take your level and make sure that string is perfectly horizontal. If it’s not, adjust the sensors by sliding them up or down. The goal is for them to be perfectly in line with each other. Small adjustments can make a big difference over a 16-foot span.
6. Tighten Those Screws
Once everything is lined up, tighten the screws back up so the sensors stay in place. Be careful not to overtighten because you could throw the alignment off again.
7. Test the Door
Now, the moment of truth. Reconnect the power and try closing the garage door. If it closes without any problems, you’re golden! If it doesn’t, you may need to repeat the alignment process.
Common Problems and Troubleshooting Tips
Here are a few things to keep in mind if you’re still having trouble:
- Flickering Lights: If the lights on your sensors are flickering, they might still be misaligned. A solid light usually means they’re working properly.
- Check the Wiring: Make sure the wires connecting the sensors aren’t damaged or loose. Replacing bad wiring is a quick fix.
- Obstructions: Ensure there’s nothing blocking the path of the infrared beam—sometimes, even something as small as a leaf can interfere.
Can You Bypass Garage Door Sensors?
I get it, sensors can be a pain sometimes, and you might be tempted to bypass them. Before you go that route, know that it’s a safety risk. Your garage door might close on things it shouldn’t, like your car or your foot. If you’re seriously considering it, check out how to bypass garage door sensors for more info, but proceed with caution.
Why Are My Sensors Still Not Working?
If you’ve done everything by the book and your garage door is still giving you a hard time, the sensors themselves might be faulty. In that case, it’s time to replace them. Follow the same steps as aligning, but with new sensors.

In-Depth Q&A on Garage Door Sensor Alignment
How do I know if my garage door sensors are aligned?
If your garage door sensors are aligned properly, the indicator lights on both sensors should be solid. If one light is off or blinking, that sensor might be out of alignment, and you’ll need to make small adjustments until the lights are solid again.
Why is my garage door not closing even though the sensors are aligned?
If your sensors appear aligned but the door still doesn’t close, you may have faulty sensors, damaged wiring, or an issue with the garage door opener itself. Check out signs of garage door opener issues for more insights.
What should I do if the sensors get bumped?
Garage door sensors are pretty delicate, and they can get knocked out of place if they’re bumped by something like a car or trash can. If that happens, just follow the steps above to realign them, and be extra careful with objects around the garage.
Can I reset my garage door opener after realigning sensors?
Yes, after aligning your sensors, it’s a good idea to reset your garage door opener to ensure everything syncs up. If you’re using a LiftMaster system, here’s a handy guide on how to reset the LiftMaster keypad.
