What Features Should Have A Good Quality Refrigerator Surge Protector

EMI/RFI Noise Filtering

EMI/RFI noise filtering removes electromagnetic and radio frequency interference preventing the refrigerator from any electrical damage. 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 with 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.

Safety Rating

UL 1449 standards cover the design, construction, performance, and tests of electrical surge protective devices (SPDs) such as receptacles and plug-in type ESPDs for electrical circuits. So try to purchase a model that has a UL certification for durability and safety. This standard will protect you and your appliances from voltage surges.

Voltage Clamping

Voltage clamping of a surge protector is when the voltage of the surge protector is clamped at a specific level. This is done for a number of reasons, including to prevent damage to equipment that is plugged into the surge protector.

If a surge protector is rated lower than your refrigerator voltage, you will suffer from electrical problems inside. Also, ensure the clamping voltage is below your system’s minimum operating voltage to avoid electrical issues.

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 1000 joules. If you have a high budget, you should buy a surge protector with the highest joule rating.

Diagnostic LEDs

Diagnostic lights/indicators confirm power protection and line error status. So you should ensure your refrigerator surge protector has diagnostic LED lights that can verify power and protective status. It also indicates line problems – making it easy for you to know if there is a power problem or not.


Extended warranties indicate the excellent qualities of the surge protector. However, all surge protector manufacturers are not the same, and the quality of the protectors they produce varies. Also, some are not provided with warranties for their product. I don’t think a warranty product is terrible, but if the product has a warranty, that’s fine.

Related FAQs

Is it true that a surge protector can refrigerator run faster?

No, the refrigerator will not run faster if you use a surge protector. However, it is the only additional safety device to protect the fridge from damage caused by sudden spikes or voltage fluctuations.

Can a power surge damage my refrigerator?

Yes, it will. During power surges, appliances like refrigerators may suffer damage due to sudden current spikes. Fridges usually have fuses that prevent them from overheating. However, your refrigerator may be damaged or catch on fire when it cannot handle high power surges.

How do I know if a surge protector is compatible with my refrigerator?

When choosing a surge protector for your refrigerator, be sure to select one that is compatible with the specific make and model. In most cases, you can find this information in the owner’s manual. If you are still unsure, you can always contact the manufacturer directly.

Final Thoughts

Without depending on the refrigerator’s default fuse, it is better to protect your fridge from power surges with a good surge protector. This appliance provides an extra layer of protection against voltage fluctuations and power surges.

I have discussed the buying guide/what to look for features and reviews of some popular fridge surge protectors available on Amazon. Now it is your turn to decide which one you will choose.

Remember that the above surge protectors are not only best for fridges, but you can use them on many other high-power/voltage appliances like washing machines, dryers, dishwashers, etc.
