Were your Antioch garage door sensors knocked out of alignment?

Quiet as mice, the sensors stand sentry on either side of your Antioch garage door. They’re ready to leap into action whenever called upon. They’re there to protect you, your loved ones, your dog and your possessions.

Garage door sensors quietly project laser beams across the opening to your garage door so that the garage door won’t come down on an unsuspecting child, pet or your car. When the laser is broken, while the garage door is in motion, it instantly stops the garage door in its tracks.

You don’t see the laser. You probably don’t even notice the sensors. But they’re still there doing their job, well, unless …

To perform their duty, garage door sensors need to cooperate effectively. This means that the laser beam has to be precisely aimed to complete the circuit between the two sensors. The sensors are mounted near the floor on either side of your Antioch garage door. They are wired to the garage door opener so that, when the laser beam is broken, they tell the garage door opener to stop.

What if the sensors are not properly adjusted? No doubt, when they were installed, they were adjusted so the laser beam communicated between the two sensors. But since then, well, things can happen.

Suppose you’re rearraigning things in the garage. You don’t even realize it when a box your moving pushes against another box that is up against one of the sensors. With no idea that it has happened, you’ve knocked one of the sensors out of alignment. The beam will no longer complete its circuit between the two sensors. The safety measure is no longer working.

Maybe you were sweeping leaves out of the garage in the fall or shoveling snow in the winter and bumped the sensor. The sensor are fairly solidly mounted by you can still knock them out of whack. Maybe you simply kicked one of the sensors by accident one day.

Whatever happened, if the sensors are no longer precisely aligned, you’ll have trouble with your garage door.

Sensors also can get dirty, which can also affect their operation. If you decide to clean the lenses on the sensors, be sure to do so gently so that, while cleaning them, you don’t move them. But you may want to call in a professional to check that the sensors are properly aligned and operating at peak performance. 

If you call a garage door technician out to perform annual maintenance on your Antioch garage door, one of the tasks they’ll perform is checking the sensors.
