Just like magic, you press a button on your garage door opener and your garage door opens. It couldn’t be simpler, right? While this is a simple process on the surface, behind the scenes is a complex system of sensors, infrared lighting, and other technical components to get your door to do what you want when you want it.
There are four basic types of garage door sensors: safety sensors, pressure sensors, monitoring sensors and CO2 sensors. Each has its own specific function and unique purpose, but they’re all engineered and designed for flawless execution and peerless safety. Here’s an in-depth look at each type of sensor:
Standard Types of Garage Door Sensors
Safety Sensors
Safety sensors are designed to prevent the garage door from closing on obstructions such as automobiles, pets, debris, or people. You will typically find these mounted to the rails on either side of the garage door. Using infrared beams, the sensors connect to one another and will cause the door to stop and reverse direction if anything interrupts the beams. These sensors work by identifying anything lying still or if something suddenly enters the path of the beams.
Pressure Sensors
Installed along the bottom edge of a garage door, pressure sensors will stop and reverse the door’s downward closing motion when it comes into contact with another object. These sensors are designed to detect even low amounts of pressure, providing a safeguard against the door closing on top of anyone or anything!
Monitoring Sensors
Intended for homes with several different garage doors, monitoring sensors alert owners whenever their doors are open. These work with receivers that are installed within the home or via an app installed on smartphones. In many cases, these sensors have the ability to close the door remotely or can be setup to close after a certain amount of time. Often, these sensors are included with home security systems, as an open garage door can be a source of vulnerability to intruders.
CO2 Sensors
Carbon dioxide buildup in a garage can be deadly! CO2 sensors employ advanced technology to continuously monitor CO2 levels in the garage and automatically open the garage door, if needed. While these types of sensors are not as common as other types of sensors, these can help keep you and your family safe.
Sensors are not only critical to the functionality of your garage door, they can be a critical point of safety for you and your loved ones.

Importance of Proper Sensor Installation and Maintenance
Proper installation and maintenance of garage door sensors are crucial for ensuring their optimal performance and the safety of your garage door system. Here are some key guidelines to follow:
Proper Installation Techniques
- Read the Manufacturer’s Instructions:
- Always start by thoroughly reading the installation instructions provided by the sensor manufacturer to ensure correct setup.
- Correct Positioning:
- Install sensors about 6 inches above the ground on each side of the garage door.
- Ensure sensors are aligned perfectly facing each other to create an invisible safety beam.
- Secure Mounting:
- Use appropriate mounting brackets and screws to securely attach the sensors to the garage door tracks or walls.
- Ensure sensors are stable and do not move or vibrate during door operation.
- Wiring Connections:
- Follow the wiring diagram provided in the instructions for connecting the sensors to the garage door opener.
- Make sure all connections are secure and insulated to prevent any electrical issues.
Regular Maintenance Practices
- Regular Cleaning:
- Clean the sensor lenses regularly with a soft cloth to remove dirt and debris that can obstruct the beam.
- Check Alignment:
- Periodically check that sensors are still aligned and adjust if necessary to maintain the safety beam.
- Inspect Wiring:
- Examine the wiring for any signs of wear or damage and repair or replace as needed.
- Test Sensor Functionality:
- Test the sensors monthly by placing an object in the path of the door while it’s closing to ensure the door reverses when the beam is interrupted.
- Professional Inspection:
- Have a professional inspect the sensors and the entire garage door system annually to ensure everything is functioning correctly.
Common Issues and Troubleshooting Tips
Homeowners may encounter various issues with their garage door sensors. Here are some common problems and practical troubleshooting tips:
Common Issues
- Misalignment:
- Misaligned sensors are a common issue that can prevent the garage door from closing properly.
- Dirt Accumulation:
- Dirt and debris on the sensor lenses can block the safety beam, causing the door to malfunction.
- Sensor Malfunctions:
- Electrical issues, worn-out components, or physical damage can lead to sensor malfunctions.
Troubleshooting Tips
- Check Sensor Alignment:
- If the garage door doesn’t close, check the alignment of the sensors. Adjust them until the indicator lights on both sensors are solid and not blinking.
- Clean the Sensor Lenses:
- Wipe the sensor lenses with a clean, soft cloth to remove any dirt or debris. This can often resolve issues where the door won’t close.
- Inspect and Repair Wiring:
- Examine the wiring for any loose connections or damage. Secure any loose wires and replace damaged ones.
- Test the Sensors:
- Place an object in the sensor’s path and attempt to close the door. If the door doesn’t reverse, the sensors might need to be replaced.
- Check for Obstructions:
- Ensure there are no objects blocking the sensor path, such as tools, toys, or debris.
- Replace Faulty Sensors:
- If troubleshooting doesn’t resolve the issue, the sensors may be faulty and need replacement. Consult with a professional for proper diagnosis and replacement.
By following these guidelines for proper installation, maintenance, and troubleshooting, you can ensure your garage door sensors operate effectively and safely.
