7 Best Surge Protector For Refrigerator 2022 [Expert Buying Guide]

If you need to know the best surge protectors for refrigerator, then you are in the right place. We have reviewed 7 models and brands of fridge surge protectors so that you can decide which one suits your needs best.

Your refrigerator is one of your most expensive investments, probably you don’t want to damage your dream refrigerator or other home appliances! So how can you protect it? One way might be with a surge protector.

Surge protectors are devices that help prevent power surges from harming your appliances. They work by regulating voltage and current spikes which could damage electronics like refrigerators or air conditioners.

There are many different types of surge protection devices on the market for refrigerators or other high voltage home devices, ranging in price and features.

After hours of research, we found what we believe might be the best choice for most people. Tripp Lite’s IBAR2-6D surge protector has a 12-amp circuit breaker and a $25,000 connected equipment warranty. This particular model has two outlets and provides 1440 Joules of surge protection for your refrigerator. The surge guard is the most popular model on Amazon.

What Features Should Have A Good Quality Refrigerator Surge Protector

Some good things to watch out for when choosing a surge protector for your fridge. These features and specifications will help you decide which model is right for your home.

EMI/RFI noise filtering

The purpose of EMI/RFI noise filtering was intended to remove electromagnetic and radio frequency interference preventing the refrigerator surge protection system. Magnetic fields can cause false tripping of the surge protector device and radio waves will not only create distortion in the current but also cause damage to your appliances.

So if you want to buy a noise filtering surge protector choose one that will have a built-in EMI/RFI noise filtration to prevent false tripping of components inside. Although it’s not mandatory for the device to have EMI/RFI noise filtration, mainly found on portable models – it’s still a good “extra” feature that will protect your fridge from damage.

Note: For a refrigerator surge protector, EMI/RFI is not necessary. It should have a surge protector or power strip that is used to protect sensitive devices like audio or video.

Safety Rating

UL is one of several firms approved to take Safety & Health Training testing from the Office of Labor Safety and Health Administration in the USA. There are some safety requirements in UL involving fridge surge protectors.

Make sure the refrigerator surge protector conforms with the standard 1449 UL for safety. This standard will protect you and your appliances from voltage surges.

UL 1449 standards cover the design, construction, performance, and tests of electrical surge protective devices (ESPDs) such as receptacles and plug-in type ESPDs for electrical circuits. So try to purchase a model that has a UL 1449 certification for durability and safety.

Voltage clamping

A fridge surge protector might limit a 6,000V surge so that fewer than 6000V are visible on the loads. Check the current rating of the refrigerator before installing a surge protector.

If a surge protector is rated lower than your refrigerator voltage, you will suffer from electrical problems inside. Also, make sure the clamping voltage is below your system’s minimum operating voltage to avoid electrical problems inside. So keep your eye out for voltage ratings matching your refrigerator to avoid any problems with electrical devices inside.

Joule Rating

Joule rating is the amount of energy that your refrigerator’s surge protector should take. A higher rating will ensure the best protection of a laptop, refrigerator/computer, or home.

So for your fridge surge protector try to look for a rating over 1200. The higher the joule rating, the better product will protect your appliances. If you have a high budget, you should buy a surge protector with the highest joule rating.

For example, a 1000 Joules surge protector might not be enough to carry the voltage that comes with a 6000-volt.

Number of sockets

If you have two fridges, a socket will probably be needed. A surge protector with a socket could still function with a lead with multiple plugs. And it’ll cost more and require more space, which is not ideal.

If you have only one fridge, don’t worry – use it anyway. But if you have two or more appliances taking up space in your kitchen, it’ll be good to have another socket.

You might need a surge protector with more than one socket for extra appliances. So if you have the intention to plug in two devices into a surge protector, you should choose 2 sockets or more.

Diagnostic LEDs

Diagnostic lights/indicators confirm power protection and line error status. Look for your refrigerator surge protection with diagnostic LED lights that verifies power and protective status.

The diagnostic light indicates the surge protection status and this light will be off to indicate that the surge protector has been properly grounded. It also indicates line problems – making it easy for you to know if there is a power problem or not.

If the light indicator is still lit after resetting, that means something is wrong with your appliance or home wiring. If there is no light, that means it’s working properly and guarding against voltage spikes and surges.

So this feature is most important and should have in a fridge surge protector. So that you may know if the device is working or not.


Long warranties indicate the good qualities of the surge protector. All surge protector manufacturers are not the same, and the quality of the surge protectors they produce varies. Also, some are not provided warranties of their product. Don’t think with no warranty product is bad. But if the product has a warranty that’s fine.

So try to look for surge protectors that have a long warranty. That is proof of its quality and durability. So if you want to buy an appliance that lasts longer, it’s good to choose one with a warranty.
