How To Fix Garage Door Sensor Genie

Garage door sensors are an essential component of your garage door system. They play a crucial role in ensuring the safety of your family and property by automatically detecting any obstacles or obstructions in the path of the door. However, like any other electronic device, garage door sensors can sometimes malfunction and cause inconvenience. If you own a Genie garage door opener and are facing issues with the sensors, don’t worry! In this article, we will walk you through the step-by-step process of fixing garage door sensor issues specific to Genie openers, so you can get your garage door back to smooth operation in no time.

1. Conduct a Visual Inspection

The first step in troubleshooting any issues with your Genie garage door sensor is to conduct a visual inspection. Start by checking if the sensors are properly aligned. Look for any debris, dirt, or cobwebs that may be obstructing the sensor’s view. Clean the sensors using a soft, lint-free cloth and ensure that there are no obstructions in their path. Also, check the sensor wiring for any signs of damage or loose connections.

2. Check the Power Source

If the sensor alignment and cleanliness seem to be in order, the next step is to check the power source. Ensure that the sensors are receiving power by confirming that the LED lights on both sensors are illuminated. If not, check the power source, such as batteries or electrical connections, and replace or repair them if necessary.

3. Adjust the Sensor Alignment

If the sensors are properly aligned and receiving power, but the garage door still won’t close, adjusting the sensor alignment may be necessary. Start by loosening the wingnuts or screws that hold the sensor brackets in place. Gently move the sensors until they are perfectly aligned with each other. Use a level tool to ensure that they are both at the same height. Once aligned, tighten the wingnuts or screws to secure the sensors in place.

4. Test the Sensor Range

After adjusting the sensor alignment, it is crucial to test their range. Stand inside the garage and close the door using the opener. As the door closes, place an object, like a cardboard box, in the sensor’s path. If the sensors are working correctly, the door should automatically reverse its movement and reopen upon detecting the obstruction.

5. Inspect and Repair the Wiring

If the above steps fail to fix the sensor issue, there might be a problem with the wiring. Start by inspecting the wires for any visible damage, such as cuts, frays, or exposed sections. Replace any damaged wiring immediately. Additionally, check the wire connections to ensure they are secure and tight. Loose wires can often result in sensor malfunctions. Reconnect any loose wires and use electrical tape or wire nuts to secure the connections.

6. Reset the Garage Door Opener

If all the previous steps have been unsuccessful, resetting the garage door opener might be the solution. To reset your Genie opener, locate the “Learn” or “Smart” button on the motor unit. Press and hold the button until the LED light on the motor unit turns off. Release the button and wait for a few moments before pressing the button again. The motor unit’s LED light should turn on, indicating that the opener has been successfully reset. Test the sensors and see if they are functioning properly.

7. Contact Professional Help

If you have tried all the above steps and are still experiencing issues with your Genie garage door sensors, it might be time to seek professional help. Contact a reputable garage door repair company or the manufacturer’s customer service for further assistance. They will have the expertise and specialized equipment to diagnose and fix any complex sensor problems.


1. How do garage door sensors work?

Garage door sensors work by emitting an infrared beam between each other. When an object interrupts this beam, the sensors send a signal to the opener, causing it to stop closing and reverse its movement as a safety measure.

2. Why won’t my Genie garage door close?

If your Genie garage door won’t close, it is likely due to a sensor issue. The sensors may be misaligned, dirty, or not receiving power. By following the steps outlined in this article, you should be able to diagnose and fix the problem.

3. How often should I inspect my garage door sensors?

It is a good practice to inspect your garage door sensors at least once every few months. Regular inspections can help identify and fix any potential issues before they escalate into more significant problems.

Yes, you can replace the Genie garage door sensors yourself if you have the necessary knowledge and tools. However, if you are unsure or inexperienced, it is best to hire a professional to ensure the job is done correctly and safely.

In conclusion, fixing garage door sensor issues with your Genie opener is a manageable task if you follow the right steps. By conducting a visual inspection, checking the power source, adjusting the sensor alignment, testing the sensor range, inspecting and repairing the wiring, resetting the opener, and seeking professional help if needed, you can effectively troubleshoot and resolve any sensor problems.
