The answer to 'why is my surge protector not working' is that the surge protector has likely failed or been damaged. Surge protectors are designed to absorb and dissipate electrical surges, but over time they can wear out and lose their ability to protect your devices. Common symptoms of a failed surge protector include no lights or indicators, outlets that no longer provide power, or devices that are not being protected.
To troubleshoot a non-working surge protector, first check the power light or indicator - if it's not lit, the surge protector may need to be replaced. You can also try plugging in another device to see if the outlets are still providing power. If the surge protector is no longer functioning, it's best to replace it with a new one rather than trying to repair it yourself. Surge protectors are relatively inexpensive, so it's usually not worth the risk to try and fix a failed one.
