The answer to 'why is my surge protector not working' is that the surge protector may have reached the end of its useful life or been damaged. Surge protectors are designed to absorb and dissipate electrical surges to protect your electronics, but over time they can become worn out and stop functioning properly.
Common symptoms of a faulty surge protector include lights not turning on, outlets not providing power, or your electronics still being damaged by power spikes. If your surge protector is no longer working, it's important to replace it to avoid potential damage to your devices. For safety reasons, it's best to have a licensed electrician inspect and replace the surge protector if needed.
