How Do I Know If My Whole-House Surge Protector Is Bad?

A whole‑house surge protector is likely bad if its status indicator shows failure or there are signs of physical damage or repeated downstream issues. Many units sacrifice themselves during a major surge, and a common cause of “not working” is the breaker feeding the device being switched off or tripped. C&T Electric LLC installs, tests, and troubleshoots surge devices at the panel and can verify the breaker and wiring integration during an on‑site check. We also include surge checks in our annual inspection program, with clear photo documentation. Our team services homes in and around Nixburg and can confirm whether replacement or simple re‑energizing is needed.

• Check the surge protector’s indicator light: off/red often means the module is spent.
• Verify the dedicated breaker for the surge device isn’t tripped or off.
• Look for burning odor, soot, or a melted housing.
• Note recurring electronics damage or nuisance trips after storms.

If you see damage or smell burning, turn off the device’s breaker and call a licensed electrician. <br/> Updated: 2026-06-18 <br/> Need help in Nixburg, AL? Call (256) 234-0007 or book online.
