Garage Door Sensor Is Yellow

If your garage door sensor is yellow, it means that the sensor is dirty or misaligned. A dirty sensor will not be able to detect the presence of the garage door, and a misaligned sensor will not be able to send a signal to the garage door opener. To fix this problem, you will need to clean the sensor and/or realign it.

Cleaning the sensor

To clean the sensor, you will need to use a soft cloth and a mild detergent. Gently wipe the sensor down with the cloth, being careful not to damage the sensor. Once the sensor is clean, dry it off with a clean cloth.

Realigning the sensor

To realign the sensor, you will need to loosen the screws that hold the sensor in place. Once the screws are loose, you can move the sensor until it is aligned with the garage door. Once the sensor is aligned, tighten the screws.

Troubleshooting

If you have cleaned and realigned the sensor and the problem persists, there may be another issue with the garage door opener. You can try resetting the garage door opener by unplugging it from the power outlet and then plugging it back in. If this does not work, you may need to contact a professional to repair the garage door opener.

Additional tips

Here are some additional tips for keeping your garage door sensor in good working condition:

Keep the sensor clean by wiping it down with a soft cloth every few months.
Make sure that the sensor is aligned with the garage door. If the sensor is misaligned, it will not be able to send a signal to the garage door opener.
