One Of The Garage Door Sensors Is Yellow

When one of the garage door sensors is yellow, it indicates that the sensor is not aligned properly or there is an obstruction blocking the sensor's beam.

To troubleshoot this issue, you can follow these steps:

1. Check for any obstructions that may be blocking the sensor's beam. This could include objects such as toys, boxes, or even spider webs.

2. If there are no obstructions, check that the sensors are aligned properly. The sensors should be facing each other directly, with no gaps or misalignments.

3. If the sensors are aligned properly, you can try cleaning the sensors with a soft cloth. Dirt or debris can accumulate on the sensors over time, which can interfere with their operation.

4. If cleaning the sensors does not solve the problem, you may need to replace the sensors. Garage door sensors are relatively inexpensive and easy to replace.

Here are some additional tips for troubleshooting garage door sensors:

- If you have a multimeter, you can test the sensors to see if they are functioning properly.

- You can also try swapping the sensors to see if the problem follows the sensor or if it is something else with the garage door opener.

- If you have tried all of these troubleshooting steps and the problem persists, you should contact a qualified garage door repair technician.
