The answer to 'surge protector not working' is that there are several common causes, including a faulty surge protector, a power issue in your home's electrical system, or a problem with the connected devices. Symptoms may include a lack of power to connected devices, no lights on the surge protector, or frequent power outages.
To troubleshoot, first check the surge protector's lights and indicators to see if it's receiving power. If not, try plugging it into a different outlet. If the issue persists, the surge protector itself may be damaged and need replacement. If the surge protector is working but devices still aren't getting power, the issue could be with your home's electrical system, which may require an electrician to inspect and resolve.
