The answer to 'GFCI outlet not working' is that a GFCI (ground fault circuit interrupter) outlet may not be working due to a variety of common issues. GFCI outlets are designed to quickly shut off power if they detect a ground fault, which can help prevent electric shocks and fires.
Some common causes of a non-working GFCI outlet include a tripped GFCI, a faulty GFCI, wiring issues, or a problem with the circuit the GFCI is connected to. Symptoms may include the GFCI not resetting, the outlet not providing power, or the GFCI tripping frequently. Solutions can range from resetting the GFCI, replacing the GFCI, checking the wiring, or addressing issues with the circuit. If you are not comfortable troubleshooting electrical issues, it's best to call a licensed electrician to diagnose and repair the problem.
