The answer to 'GFCI outlet flickering lights' is that a flickering or blinking GFCI outlet is often caused by a ground fault in the electrical system. This can be due to a problem with the GFCI outlet itself, wiring issues, or other electrical problems. Symptoms may include lights flickering, outlets not working properly, or the GFCI outlet tripping frequently.
Some common causes include faulty wiring, a bad GFCI outlet, overloaded circuits, or a ground fault in an appliance or device plugged into the GFCI outlet. In many cases, this can be a DIY fix, such as resetting the GFCI, checking for loose connections, or replacing the outlet. However, if the issue persists or you're not comfortable troubleshooting electrical problems, it's best to call a licensed electrician to diagnose and resolve the issue safely.
