The answer to 'why is my GFCI outlet outlet not working' is that there are several common causes, including a tripped breaker, a faulty GFCI, or a wiring issue. GFCI outlets are designed to trip when they detect a ground fault, which can happen due to moisture, damage, or an overloaded circuit.
If your GFCI outlet is not working, first check the reset button to see if it has tripped. If so, press the reset button to restore power. If the GFCI continues to trip, there may be an issue with the outlet itself or the wiring. You can try testing the GFCI with a GFCI tester to determine if it needs to be replaced. If the issue persists or you're not comfortable troubleshooting the problem, it's best to call a licensed electrician to diagnose and repair the issue.
