The answer to 'why is my GFCI outlet' is that GFCI (Ground Fault Circuit Interrupter) outlets are designed to quickly shut off power if they detect a ground fault, which can help prevent electric shocks and fires. Common causes for a GFCI outlet to trip or not work properly include a faulty GFCI, a problem with the wiring, or an issue with the devices plugged into the GFCI.
Symptoms of a malfunctioning GFCI outlet include the outlet not providing power, the GFCI tripping frequently, or the GFCI test button not working. Solutions can range from resetting the GFCI, replacing the GFCI, or calling an electrician to inspect the wiring if the issue persists. It's generally recommended to call a professional electrician if you're unsure of the cause or don't feel comfortable troubleshooting the GFCI outlet yourself.
