Yes, surge protectors do need to be changed regularly. Why do surge protectors wear out? That’s because each time a surge protector absorbs a surge, its internal components degrade slightly. Over time, or after absorbing a large surge, the protector’s ability to shield your devices diminishes, reducing its effectiveness.
You can determine if your surge protector needs replacing by looking for visible signs of damage, such as scorching or melting, or if it is not working as expected. Pay attention to an alarm going off, unusual clicking sounds, or if it keeps turning off unexpectedly.
Check the indicator lights; if they show a loss of protection or if the light is on but there’s no power, it’s likely a sign of failure and time for a replacement.
Additionally, if your surge protector has experienced a significant power surge or is several years old, it may be time for a surge protector expiration date, and you need to replace it.
