Why does my gfci outlet have a yellow light?

If your GFCI (Ground Fault Circuit Interrupter) outlet has a yellow light, it typically indicates a fault or a specific condition of the outlet. The specific meaning of the yellow light can vary depending on the manufacturer and the model of the GFCI outlet. However, there are a few common reasons why a GFCI outlet might display a yellow light:
1. Self-Testing: Some GFCI outlets have a self-testing feature that checks the functionality of the outlet at regular intervals. The yellow light may indicate that the GFCI outlet is in the process of self-testing. During this test, the GFCI outlet briefly interrupts the power to verify if it can properly trip and protect against ground faults. Once the self-test is completed, the yellow light may turn off, or it may change to a different color to indicate the test result (e.g., green for a successful test or red for a failed test).
2. Ground Fault Indicator: In some cases, a yellow light on a GFCI outlet can indicate a ground fault. This means that the outlet has detected an electrical leakage or a fault in the grounding system. When a ground fault occurs, the GFCI outlet automatically shuts off the power to prevent electric shock. The yellow light is a visual indication that the GFCI outlet has tripped and needs to be reset. To resolve the issue, you should investigate the cause of the ground fault, such as a faulty appliance or damaged wiring, and rectify it before resetting the GFCI outlet.
3. Wiring Issues: A yellow light can also be an indication of a wiring issue within the GFCI outlet or the electrical circuit connected to it. Loose or faulty wiring connections can cause the GFCI outlet to display a yellow light. This can be a sign of an improper installation or a wiring problem within the outlet itself. In such cases, it's important to turn off the power to the outlet and have a qualified electrician inspect and repair the wiring.
It's worth noting that the meanings of the light indicators on GFCI outlets can vary, so it's important to refer to the manufacturer's documentation or contact their customer support for specific information regarding your particular model. They can provide you with accurate information about the yellow light and guide you on troubleshooting steps or necessary actions to resolve the issue. Additionally, if you are uncertain about dealing with electrical components or troubleshooting, it's always recommended to seek professional assistance to ensure safety and prevent further damage.
