Understanding the Genie Garage Door Opener Sensor

What is a Garage Door Opener Sensor?

A garage door opener sensor is a safety feature designed to prevent accidents and injuries. It consists of two sensors positioned on either side of the garage door, typically about six inches off the ground. These sensors create an invisible beam that, when interrupted, stops the garage door from closing.

Why are Sensors Important?

  • Safety: Sensors prevent the garage door from closing on people, pets, or objects.
  • Compliance: Modern building codes require garage doors to have functioning safety sensors.
  • Peace of Mind: Knowing your garage door won’t accidentally close on someone or something gives you confidence in its safe operation.

Reasons for Bypassing the Sensor

When Might You Need to Bypass the Sensor?

  1. Malfunctioning Sensor: If the sensor is damaged or malfunctioning and you need to use the garage door urgently.
  2. Misalignment: Sometimes, sensors can become misaligned and cause the door to stop functioning.
  3. Electrical Issues: Problems with the wiring or electrical components might necessitate a temporary bypass.
  4. Obstructions: Debris or dirt blocking the sensor can prevent the door from closing.

Safety Considerations

Bypassing the sensor is not a permanent solution and should only be done when necessary. Always address the underlying issue with the sensor as soon as possible to ensure your garage door operates safely.

  • Wire nuts
  • Electrical tape
  • Safety glasses
  • Step ladder

Step-by-Step Guide

1. Turn Off the Power

Before you start, ensure that the power to the garage door opener is turned off to avoid any electrical hazards. Unplug the opener from the outlet or turn off the circuit breaker that controls the garage door.

2. Locate the Sensors

Find the sensors on either side of the garage door. They are usually mounted on the door tracks, about six inches above the ground.

3. Inspect the Sensors

Check for any visible damage or obstructions. Ensure that the sensors are clean and properly aligned. Misalignment is a common cause of sensor issues.

4. Disconnect the Sensors

Using a screwdriver, remove the screws that hold the sensors in place. Carefully disconnect the wires connected to the sensors. Be sure to note which wire goes where, as you will need to reconnect them later.

5. Bypass the Sensors

To bypass the sensors, you will need to connect the wires directly. Twist the wires together (one from each sensor) and secure them with wire nuts. Ensure the connection is tight and secure.

6. Secure the Wires

Once the wires are connected, use electrical tape to secure them and prevent any short circuits. Make sure the wires are not dangling or in a position where they could get caught in the door mechanism.

7. Test the Garage Door

After bypassing the sensors, turn the power back on. Test the garage door opener to ensure it is functioning correctly. The door should open and close without any issues.

8. Restore the Sensors

Remember, bypassing the sensors is a temporary fix. Replace or repair the sensors as soon as possible to restore the safety features of your garage door opener.

Troubleshooting Common Sensor Issues


  • Problem: Sensors are not aligned correctly.
  • Solution: Adjust the position of the sensors until the indicator lights are solid.

Dirty Sensors

  • Problem: Dirt or debris is blocking the sensor.
  • Solution: Clean the sensors with a soft cloth to remove any obstructions.

Wiring Issues

  • Problem: Faulty wiring or loose connections.
  • Solution: Check the wiring connections and ensure they are secure. Replace any damaged wires.

Electrical Interference

  • Problem: Interference from other electrical devices.
  • Solution: Ensure that the sensors are not near other electronic devices that could cause interference.

Importance of Professional Help

While bypassing the sensor can be a quick fix, it is essential to seek professional help to address the underlying issue. A qualified technician can diagnose and repair the problem, ensuring your garage door operates safely and efficiently.


Bypassing the Genie garage door opener sensor is a temporary solution that can help in emergencies. However, it is crucial to restore the sensor functionality as soon as possible to ensure the safety and compliance of your garage door system. Regular maintenance and prompt repairs can prevent sensor issues and keep your garage door operating smoothly.
