In this guide, we’ll walk you through the steps on how to reset garage door sensors, realign them, and even repair the sensors when needed. Signs You Need to Reset or Realign Your Garage Door Sensors If you notice any of these issues with your garage door, it might be time to reset or realign the sensors: 1.  The door starts to close, but then reverses or refuses to close completely. 2.  The sensor lights are flickering, or there’s no light at all, indicating a misalignment or connection issue. 3.  The door reverses unexpectedly, even though there’s nothing in its path. 4.  The motor sounds strained, but the door won’t move properly, which can be a sign of sensor interference. 5.  The manual override works, but the automatic opener doesn't, pointing to a problem with the sensors. If you’re noticing these signs, a reset or realignment may be all you need. How to Reset and Realign Garage Door Sensors Follow these simple steps for how to reset garage door sensors and get your system back on track: 1.  Ensure Safety First: Before you begin, disconnect the power to your garage door opener. This will prevent any accidental activation while you work. 2.  Locate the Sensors: The sensors are typically located at the bottom of the tracks on either side of the door. These are small, box-like devices near the floor. 3.  Clean the Sensor Lenses: Dust, cobwebs, or dirt can block the sensor’s functionality. Use a dry cloth to gently clean the lenses and remove any debris. 4.  Realign the Sensors: How to realign garage door sensors? Simply adjust the sensors until they face each other directly. Both sensors should have steady indicator lights when aligned properly. 5.  Secure the Sensors: If the sensors are loose or misaligned, tighten the brackets or screws to keep them in place. 6.  Reconnect Power and Test: After realigning and securing the sensors, plug the opener back in. Test the door by trying to close it. If the door moves without reversing, the sensors should be functioning correctly.
