How do you know if a surge protector has gone bad?

Simply examine your surge protector to see if you can spot a red or green blinking light on the outside of the device. Please note that this is not a foolproof system. Just because there is no flashing light does not always mean your device is fine. However, if it is flashing, you definitely need a new one.

What do the lights on my surge protector mean?

When both lights are on, you know the surge protector is operating as it should. The surge light means that the surge protector is functioning and ready to protect. If this light goes out you know you have experienced a surge and the surge protector will no longer protect.

Are surge protectors supposed to blink?

If the blinking/flickering light on your surge protector is red or orange, it is most likely a power light that indicates that a surge protector has been turned on or off. If that red or orange light has neon bulbs, they will degrade over time. This causes them to blink and flicker.

When should you replace a surge protector?

two years
Most estimates put the average lifespan of a surge protector at three to five years. And if your home is subject to frequent brownouts or blackouts, you might want to replace your surge protectors as often as every two years.

Does a surge protector only work once?

There’s no exact lifespan we can give you, and it varies from area to area — it depends how many surges occur in your area as well as how many joules your protector can absorb. Many people recommend replacing a surge protector every two years or so, but any recommendation like this one can only be a rule of thumb.

What happens when a surge protector trips?

When a circuit breaker trips, it means there was too much draw on that circuit. The switch temporarily shuts off the circuit, and you’ll lose power to part of the house. When this happens, we recommend you shut off all appliances in the area and unplug the outlets.

What does a red and green light mean on a surge protector?

The red light indicates that the surge protector is on. The green light indicates the ground is on and is working.

Why is my power strip light blinking?

Does a surge protector prevent blowing a fuse?

A fuse, then, is a very drastic form of protection: if anything happens, it shuts off the electricity completely. A surge protector is designed to smooth out smaller fluctuations in voltage and it doesn’t normally shut down the circuit when a problem occurs.

Do surge protectors make noise?

Yes, surge protector makes noise. This is true for all electrical devices and components. However, surge protectors are not loud. Even though they are supposed to click whenever they encounter a surge, surge protectors that produce loud clicks, buzzing, crackling, and popping are most likely faulty.

How do I know when my surge protector needs replacing?

It’s practically impossible to tell exactly when a surge protector stops functioning as intended. Some surge protectors have built-in lights that are designed to alert you to this problem and inform you when the protector needs to be replaced. However, you can’t necessarily rely on these lights.

How do sursurge protectors work?

Surge protectors aren’t magic. When they receive a power surge from the electrical outlet they’re plugged into, they have to do something with that extra voltage to get rid of it and shield the connected devices from it. A typical surge protector uses a component called a metal oxide varistor (MOV).

Does homeowners insurance cover power surge damage?

One thing that is worth noting is that many home insurance policies will NOT cover power surge damage if there is no surge protector in place. Likewise, some insurance providers may even choose not to cover your losses if you are found to have been relying on an old, expired surge protector.

How many electrical devices can a surge protector protect against?

If you have a single surge protector standing between an electricity surge and 25 electrical devices, you could be asking for trouble. There is no perfect ratio, but you should at least have a single protector for each individual room in your house.
