A surge protector controls the voltage that affects your electronics. Voltage is a type of electric pressure that can become excessive and damage equipment if it’s not regulated. A surge protector prevents this damage through metal oxide varistors, or MOVs. These MOVs actually absorb dangerous, excess voltage during a power surge. There are different types of surge protectors, but one that’s common resembles a power strip. Like everything else, it can fail due to damage or just wear and tear.
Signs Your Surge Protector Isn’t Working
Surge protectors can last between three and five years, but their lifespan can be shorter if you live in a place where there are a lot of power outages. Even if power outages are rare where you live, over time the MOVs stop absorbing excess voltage as well as they used to. There are a few signs of trouble.
The Indicator Light Is Off
A surge protector’s indicator light tells you that it’s working. When it goes dark, that means the device is dead or isn’t working the way it should.
You Notice Damage
You should replace your surge protector if you see any signs of damage. This can range from cracks if the device was dropped. Burn marks around the outlets are obvious signs that you should invest in a new surge protector. This is also true if parts of the surge protector look melted or are discolored.
It No Longer Protects Your Electronics
If you notice that one or more of your electronics suffered damage after a power spike despite your surge protector, it’s time to get another one. One obvious sign is that the appliance or device no longer works. Other signs are burnt, discolored, vibrating or smoking outlets and strange smells. You may also notice that your lights buzz, grow dim or flicker and that wires are suddenly frayed.
Guarding Against Surge Protector Damage
Before your old surge protector’s life span is done, there are things you can do to protect it and your electronics. During storms, you can simply unplug it. This unplugs the appliance and devices attached to it and protects them that way. You might want to speak to a professional electrician about installing a whole-house surge protector if you live in a place where power outages are common.
