A surge protector is a device that typically provides protection to electrical equipment from power surges and spikes in voltage. How can you tell if your surge protector is bad?

If you’re looking for a way to tell whether your surge protector is doing its job, examine it and see if there’s a red or green light blinking on the outside of the device. LED is green means that it is 100% functional and ready to protect your appliances should a power surge occur. While this isn’t foolproof (you might have an issue with other power cords connected to outlets).

It’s important to know because if the answer is yes, then it needs replacing. In this blog post, we will go over some of the symptoms of a faulty surge protector so you can figure out whether or not yours needs to be replaced.

What Are Surge Protectors?

A surge protector, also known as a power conditioner, is an electrical safety device that is designed to protect electronic devices from voltage spikes. It is a tool that can be used to both reduce the risk of personal injury and property damage due to a voltage spike. A surge protector reduces the flow of electric current to a rate that is safe enough for the devices connected by cables without overloading them.

The importance of having a good surge protector cannot be stressed enough. A good surge protector will not only protect your electronics but will also cut out any chance of electrocution or fire hazard. There are various types of surge protectors out there. Each one with its own purpose and need.

How to Tell If a Surge Protector Is Bad?

There are many reasons why people decide to invest in a surge protector. One of the main reasons is to prevent electric surges that could harm their home and its appliances. This article will help you identify if your surge protector is bad and what to do about it.

Some signs that you may need to replace your surge protector:

#1. Surge protectors are designed to last a specific amount of time. Most estimates put the average lifespan at three years, but if your home suffers from frequent brownouts and blackouts you may want to replace it after only two years as they can’t handle those types of situations well in general.

#2. It shorts out or doesn’t fit properly. Is your power going off when the electrician comes to visit? This could be a sign that the outlet is not securely in place and needs to be reattached.

When it comes to protecting your home, you want only reliable products installed on all outlets throughout your house. If you have an older home with a bare switch box, you will definitely benefit from installing this type of protection.

The PST-8 uses a circuit design that has been shown to reduce repair or replacement rates below 0.005% compared to other surge protectors on the market.

#3. Check for proper grounding. Outlets must be grounded before any other electrical work can begin within a building’s walls, including the installation of a new surge protector. Make sure there are no tripped circuits, and that the breaker isn’t stuck in the off position.

#4. Has your surge protector been hit? If it has, then you must replace it immediately. This is one of those instances where the old saying “you get what you paid for” comes into play.

The average home doesn’t see power surges that exceed 6,000 volts (PDF). However, this does not mean that they are safe.

Do not wait until there is a power surge to remove any damaged equipment from your home’s electrical outlets. Your property will be protected if there are no power surges that affect your appliances, but an immediate replacement of damaged devices prevents more severe issues from occurring within your walls or on other parts of the electrical grid.

#5. Replace worn-out outlets and cords. Power surges can come from inside and outside sources, so make sure that all cables are securely placed in their sockets, the plugs are tight, and that the cord is not frayed around the connector.

#6. Look for a blinking LED light or something out of place. The fact that this surge protector LED is green means that it is 100% functional and ready to protect your appliances should a power surge occur.

If your surge protector doesn’t have an indicator light to let you know it’s working, then make sure your appliances continue running normally when there is no power outage in your area.

#7. In fact, according to the Institute of Electrical and Electronics Engineers, most power surges in homes doesn’t even approach this level since the majority occur at low voltage levels between 2-volts and 4-volts.

It also means that you need more than just an energy-absorbing MOV designed for your surge protector.

If you suspect that your surge protectors might be bad, then contact a licensed electrician before anything else. They will come out and inspect everything to ensure you don’t have a bigger problem within your home’s walls.

How do you reset a surge protector?

There are a few different ways that you can reset a surge protector:

1. Unplug the device and use the reset button to manually restart it. You should find the button on the front of your surge protector. It will either be labeled as “RESET” or have an icon of a power cord with an arrow going into a circle and then coming out, usually with the words “POWER” or “ON” over it. To find it, slide the faceplate towards one side of the device for easy access to the rest buttons. If this doesn’t work, move on to option two.

2. Unplug your devices that are plugged in and then plug them back in again to reset them. This is a good way to troubleshoot any intermittent connection issues you may be having.

3. Unplug the surge protector for a few minutes and then plug it back in again, plug your devices into the socket and see if the issue persists. Sometimes surges can leave an electrical charge behind that needs time to dissipate before you will get a good connection when using electrical equipment. This is more likely to happen with older surge protectors than newer ones as they are less resistant to this type of thing happening. You should immediately replace an older model if this happens as it could easily cause problems down the line for other connected devices or even start a fire if left unchecked over time.

4. Reset your main circuit breaker if none of these steps work first. This is the last resort, but can sometimes work if the issue lies within your home’s electrical system rather than your surge protector.

A surge protector is a device that plugs into the wall and protects your electronics from power surges. It’s important to know how to tell if it has been compromised in order to protect your expensive devices from damage. There are some ways you can check, such as using an outlet tester or plugging something else into the socket and checking for sparks coming out of the holes on top of the cord (especially if there is no light). Check with any outlets where you have experienced issues before purchasing a new one because sometimes they may not be working properly but just need some minor repairs!


01. What does the green light mean on a surge protector?

The green light on a surge protector means “everything is okay, you don’t need to worry about it.”

02. Do surge protectors stop working after a surge?

Generally, a surge protector will cut off power to the electrical system. The objective of a surge is to take over the electrical system that it is connected to and this will make it malfunction. This is why surge protectors are needed because they protect your electronics from the voltage spikes that are associated with surges. If a surge is powerful enough, it can damage your electronics without the use of a surge protector. However, in most cases, surges are not that strong and do not destroy your system. In this situation, you will find that your surge protector is still working properly.

03. Can a faulty surge protector trip a breaker?

Yes, a faulty surge protector can trip a breaker.

04. Do surge protectors go bad with age?

The answer to the question is that surge protectors can go bad with age, but it varies with the device. This is because the damage caused by surges depends on how many times they happen, and this is a variable that you can’t control. Surge protectors sometimes need to be replaced every five years or sooner if they fail an inspection.

05. Do Surge Protectors Wear Out?

Yes, this is governed by the surge protector’s design. A typical surge protector will be designed specifically for a certain number of surges (and withstands a certain number of surges at a predetermined voltage level). Once the protector has “worn out” it will need to be replaced.
