If you own a Craftsman Garage Door Opener, you know how convenient it is to use a remote control for opening and closing your garage door. However, if you encounter issues with the remote sensors, it can be frustrating to troubleshoot. In this article, we’ll delve into Craftsman Garage Door Opener Remote Sensors, explaining their function, how they can sometimes fail, and how to fix common problems.
Whether you’re dealing with a malfunctioning sensor, troubleshooting issues, or simply looking to understand how the sensors in your Craftsman Garage Door Opener work, this article will provide you with the information you need to ensure smooth and safe garage door operation.
What Are Craftsman Garage Door Opener Remote Sensors?
Craftsman Garage Door Opener Remote Sensors are critical components of the garage door system, responsible for ensuring that your door opens and closes properly and safely. These sensors work in tandem with the remote control to communicate with the garage door opener, allowing it to function smoothly.
Typically, garage door openers use two sensors that are positioned at the base of the garage door tracks, facing each other. Their primary purpose is to detect any obstacles in the door’s path. If something obstructs the sensor’s line of sight, the door will reverse direction to avoid damage or injury. The sensors are aligned so that the beams they emit must remain uninterrupted to avoid malfunctions.
Craftsman Garage Door Opener Remote Sensors are an essential safety feature, and they work by:
- Detecting Obstacles: The sensors detect if something is in the way of the door’s path. This prevents the door from closing on cars, people, or other obstacles.
- Ensuring Proper Alignment: If the sensors become misaligned, the system may fail to function correctly, causing the door to remain closed or fail to reverse when an obstacle is detected.
- Sending Signals to the Opener: The sensors send a signal to the opener, telling it whether it is safe to close the door or not.

These sensors enhance safety by ensuring that the garage door cannot close when something is in its way. But what happens if the sensors stop working correctly?
How Do Craftsman Garage Door Opener Remote Sensors Work?
The Craftsman Garage Door Opener Remote Sensors use infrared technology to communicate. Here’s how they typically work:
- Emitting Infrared Beams: One sensor (usually the sender) emits an infrared beam across the door’s opening. The other sensor (receiver) detects this beam. The sensors are aligned to ensure that the beam is uninterrupted when everything is functioning properly.
- Communication with the Opener: When the sensors detect that the beam is being blocked (by an object, person, or vehicle), they send a signal to the opener to reverse the door’s movement. This process is automatic, ensuring that the garage door opens or closes only when it’s safe to do so.
- LED Indicator: On most Craftsman Garage Door Opener Remote Sensors, you will find an LED light indicator on the sensor. This light provides valuable feedback, signaling whether the sensor is aligned correctly or if it has detected an obstruction. If both lights on the sensors are lit, it generally means the system is working as intended.
Why Do Craftsman Garage Door Opener Remote Sensors Malfunction?
Like any other part of your Craftsman Garage Door Opener, sensors can malfunction or fail over time. Understanding the common causes of malfunction will help you identify and resolve the issues quickly.
Here are some common reasons why Craftsman Garage Door Opener Remote Sensors may malfunction:
1. Misalignment of Sensors
One of the most common reasons your Craftsman garage door opener remote sensors may fail is sensor misalignment. If the sensors are not properly aligned, the infrared beam will be interrupted, and the door may not function as expected. Misalignment can happen easily, especially if the sensors are accidentally bumped or jarred by the door or other objects.
2. Dirty or Blocked Sensors
Dirt, dust, spider webs, or any physical obstruction on the sensor lens can interfere with the sensor’s ability to detect the beam. It’s important to clean the sensors regularly to ensure they are not obstructed and function properly.
3. Wiring Issues
The wiring that connects the Craftsman garage door opener remote sensors to the opener may become damaged or disconnected. This could be caused by wear and tear, physical damage, or issues with the power supply. Damaged wiring can prevent the sensors from sending signals to the opener.
4. Sensor Failure
Over time, the sensors themselves may experience internal failure due to factors such as electrical surges or age. If the sensors are no longer sending or receiving the infrared beam properly, they will need to be replaced.
5. Interference from Other Devices
Some electronic devices or external sources of interference can disrupt the infrared signal. This is less common, but it can happen, especially in areas with many electronic devices that emit signals.
How to Troubleshoot Craftsman Garage Door Opener Remote Sensors
If your Craftsman garage door opener remote sensors are not working properly, follow these troubleshooting steps to resolve the issue:
1. Check for Misalignment
Start by checking the alignment of the sensors. Here’s how:
- Stand directly in front of the sensors and inspect them.
- Ensure both sensors are facing each other and aligned properly. They should be at the same height and directed towards each other across the door opening.
- If you notice that one sensor is out of alignment, gently adjust it until both sensors are aligned properly.
- Once aligned, the LED lights on the sensors should be solid, indicating proper communication between them.
2. Clean the Sensors
Dirt or obstructions on the sensor lens can disrupt the infrared beam. To clean the sensors:
- Use a soft cloth to gently wipe the lens on both sensors.
- Ensure that there is no dirt, dust, or spider webs blocking the sensor’s line of sight.
- Avoid using harsh chemicals or abrasive materials to clean the sensors.
3. Inspect the Wiring
Check the wiring that connects the sensors to the garage door opener. If the wires are frayed, damaged, or disconnected, the sensors may not work properly. If you find any issues with the wiring, it may be best to call a professional technician for repairs or replacement.
4. Replace the Sensors
If the sensors are still malfunctioning after checking the alignment, cleaning them, and inspecting the wiring, the sensors may need to be replaced. This is especially true if the sensors have sustained internal damage or are no longer sending or receiving signals. You can purchase replacement sensors from a Craftsman retailer or a licensed professional.
Maintenance Tips for Craftsman Garage Door Opener Remote Sensors
To ensure your Craftsman Garage Door Opener Remote Sensors continue to work well, follow these simple maintenance tips:
- Regularly Clean the Sensors: Clean the sensor lenses with a soft cloth to prevent dust or dirt buildup.
- Check Sensor Alignment: Periodically check the alignment of the sensors, especially if the door is not functioning properly.
- Inspect for Obstructions: Make sure the area around the sensors is free of obstacles, such as boxes, vehicles, or other items.
- Check Wiring: Inspect the wiring occasionally for signs of wear and tear.
Conclusion
The Craftsman Garage Door Opener Remote Sensors are an essential safety feature that ensures your garage door operates safely and efficiently. By understanding how these sensors work, knowing common causes of malfunction, and following the troubleshooting steps in this guide, you can keep your garage door system functioning optimally.
If you encounter persistent issues with the sensors, don’t hesitate to contact a professional to help you diagnose and fix the problem. Proper maintenance and care will ensure that your Craftsman Garage Door Opener remains in excellent working condition for years to come.
