Surge protectors are a great way to ensure that our expensive electronics stay safe from electrical damage. But how can you tell if a surge protector is bad or not?

A surge protector can become bad in several ways. It can become worn out due to age, or it may become damaged due to a power surge or lightning strike. Some signs may include frequent tripping, not resetting, not supplying power, etc.

By understanding the signs of a bad surge protector, you can make sure your devices are protected from power surges and lightning strikes. So read on to find out how to tell if your surge protector needs to be replaced.

How Can You Tell If A Surge Protector Is Bad Or Not

How Can You Tell If a Surge Protector Is Bad?

When the indicator lights keep flickering it means the surge protector is not okay. But all protectors are not made the same way. So we may need to check the following things to know whether it is bad or not.

Signs of a Bad Surge Protector:

  • Check the surge temperature of the surge protector while it is plugged in. If it is too hot than normal you assume it is not working perfectly.
  • The wires of the surge protector have a limited capacity. Due to excessive usage with high loads, the wires can wear out and their insulation can be damaged. If you notice any sign of these, you must change the wires as soon as possible.
  • Often there can be a smell of burning or ozone from the surge protector. If you find this happening, you need to consider that something is wrong with your protector.
  • There is normally more than one outlet in a surge protector. If you check that an outlet is not working or the fuse is cut off, you can tell that your surge protector is in bad condition and needs to be repaired.

How to Test a Surge Protector?

There are some quick ways to test a surge protector.

First of all, you need to check if there is any warning or beeps while plugged in. If there is a red LED or continuous beeping sound, it is an indication that your surge protector is not functioning well.

Secondly, reset your surge protector and see if there is any notification after it turns on again. If there is a continuous alarm, then it means your protection system is not working.

The beeping and alarms are caused due to the following problems:

  • If there is a bad source problem.
  • If the ground line is not properly connected or has issues.
  • The wiring is not okay or has a problem.
  • The hardware is out of service.
  • The protection system is no longer active.

Tips for Maintaining a Surge Protector

Maintaining your surge protector is an important part of ensuring that it continues to function properly and protect your electronics. Here are some tips for maintaining your surge protector:

Check the expiration date: 

Most surge protectors have a lifespan of about three to five years. If your surge protector is past its expiration date, it may not be able to provide the same level of protection as it did when it was new.

Keep it clean:

Look for any visible signs of damage, such as frayed cords or broken outlets. If you notice any damage, it’s important to replace your surge protector as soon as possible.

Use it properly: 

Make sure you’re using your surge protector correctly by plugging it into a properly grounded outlet and only using it with the types of devices it’s designed to protect. Overloading the surge protector can cause it to malfunction.

Test it regularly: 

Use a voltage tester to ensure that your surge protector is functioning properly. If the tester indicates a problem, it’s time to replace your surge protector.


It is important to be able to tell if a surge protector is bad or not so that you can make sure your devices are properly protected. By understanding the signs of a bad surge protector, you can make sure to replace a defective one before it causes any damage to your devices.

Remember to always check your surge protectors periodically to make sure they are in good working condition, and replace any that are not. By doing so, you can ensure that your devices are safe from power surges and lightning strikes.
