The answer to 'why is my surge protector outlet not working' is that there are several common causes, including a tripped circuit breaker, a faulty surge protector, or a problem with the electrical wiring. Surge protectors are designed to protect your electronics from power surges, but they can fail over time or become damaged.
First, check the circuit breaker that powers the outlet your surge protector is plugged into. If the breaker has tripped, simply reset it. If the breaker trips again, there may be an issue with the wiring that requires an electrician to inspect. Next, inspect the surge protector itself - the indicator lights should be on if it's working properly. If the lights are off, the surge protector may need to be replaced.
