How To Choose Stabilizer For Refrigerator

It would be best if you did not overlook the fact that most of the regions in India have an irregular power supply or frequent voltage fluctuations that may cause serious damage to your electrical appliances.

If you’ve delayed the purchase of a voltage stabilizer for fridge, then you should get a good one right away.

But is buying a stabilizer for fridge as easy as driving to the market and selecting one? No, any stabilizer will cost you a decent amount of money, and since it protects your fridge then in case it’s ineffective, it will cause more harm than any benefit. So it would help if you considered a few factors to narrow down your choices to make sure your investment doesn’t go to waste. 

What does A Stabilizer Do? Do We Need Stabilizer For Refrigerator?

A very common question you might think is that do we need a stabilizer for refrigerator even if our refrigerator is brand new? Well buying one right off the bat will make sure that it is completely safe during operation and it will even take away the hassle for going shopping especially to get a voltage stabilizer. 

Also, a stabilizer is a must-have for air conditioners and fridges. Some people even use it for their television sets. Moving on to the other question about the working of a voltage stabilizer, so a voltage stabilizer feeds constant voltage supply to your electrical gadgets. The voltage stabilizer works on the principle of a transformer where the input current is connected with primary and output is connected with secondary windings. There is an electromagnetic relay established between both coils that compensate for lost voltage even in case of low voltage. 

In any stabilizer, voltage corrections are carried by two definitive operations that are called boost and buck operations. The switch between these operations can be either done manually or electronically by the electronic circuit. The boost operation as per its name increases the voltage, while the buck reduces the voltage in case of a surge. 

There are three types of voltage stabilizers: Relay Type, Servo Controlled and Static Voltage Stabilizers.

You need to first calculate the power consumption of your refrigerator when connected to the stabilizer and especially when it is properly operating. It is significant to analyze power consumption while the appliances are operating as the appliance consumes double the amount of power as it starts then it does while operating. 

You should also check voltage, power and current rating of the stabilizer. It is usually mentioned in the specification sticker in the manual or located near a power socket. As per Indian standard service, voltage is 230VAC, 50 Hz. To get maximum power, you should multiply “230 x Maximum current” of the appliance connected to the stabilizer. You should add a good twenty per cent margin to derive your suitable stabilizer rating. 

Then you should find out about the voltage fluctuations in your locality, and if it is very high, then you should go for a wide-range stabilizer. While you’re at it, look for a stabilizer that offers great performance, warranty and features.

Features To Look For In A Stabilizer

Your purchase can be both good or bad, depending on how well you analyze your needs and choose to invest in a voltage stabilizer. If you’re getting troubled by the question about how do I choose a stabilizer then quickly read over these things that you should look for while buying a stabilizer. 

1. Mounting

It’s unsafe to keep your voltage stabilizer on the ground as it may end up getting wet or be damaged so a lot of models can be mounted or placed at higher levels. 

This placement is done to ensure maximum safety and prevent any case of an electrical fire, shock etc. You should see if your house has any possible place where you can get your stabilizer mounted.

Since the stabilizer works on electricity, it mustn’t get wet, so you should check if the designated wall has any water seepage issues. After determining the location of the stabilizer, you should see if the product you’re buying offers free installation so that you don’t have to spend extra money on hiring professionals for installation.

You can even install the stabilizer yourself if you are good with electrical wiring and fixing. If that’s not the case with you, then we highly recommend getting professional help. 

2. Indicators

Voltage Stabilizer Indicators

A lot of people don’t realize the significance of indicators concerning the functioning of a voltage stabilizer and end up buying a stabilizer that doesn’t have good indicators or suitable ones to suit their needs. It leads to inconvenience in operating the stabilizer as indicators help you understand how much voltage has been regulated to maintain a constant supply to the connected appliance. 

There are different types of indicators available in various models like LCD TV, LED TV and Music systems. You should take a look at all these types and then select one that best resonates with you and your requirements. 

3. Time Delay System 

During a momentary power failure, the compressor gets locked, and voltage flow is interrupted. This interruption causes the motor to draw heavy current and gets overheated which in turn may lead to damage to either the compressor or the whole wire set-up of the appliance.

Time delay feature prevents any such mishaps, and this is an important feature as it ensures that there is some time in which the compressor can maintain the voltage fed to the connected appliance during a short power cut. It is intelligent as well as a necessary feature that allows your voltage stabilizer to provide you with satisfactory performance.

Some models have incorporated smart technology that offers even more efficient performance in stabilizing the voltage level in case of power failure. 

4. Digitized

Companies always come up with new technologies to make your everyday use appliances smarter and easier to operate. It has been done in case of stabilizer as well as the voltage stabilizers have been digitized. They easily adapt when shifted from one device to another and are completely digitized. 

You can even connect them to generators, and they’ll adapt easily while keeping optimum performance. Getting digitized and more adaptable makes them more reliable. It also takes away the headache of spending a lot of money while installing the stabilizers or connecting them to any device. 

5. Overload protection

Voltage Stabilizer Overload Protection

Even the best protective devices may fail or become inefficient if they’re pushed beyond their limits, and for stabilizers, this limit is known as the maximum voltage they can regulate. Beyond this limit, the stabilizer starts getting overheated that may lead to fire hazards. 

To prevent such mishap from happening stabilizers are provided with an overload protection circuit that prevents overheating of the stabilizer in case of emergencies and prevent any damage or fire. 


Power outage and voltage fluctuations are very common problems faced in India. These fluctuations can easily harm your electrical appliances, and this is why you need a good voltage stabilizer for your fridge but buying one can be a daunting task as there’s no real help available on how to choose stabilizer for refrigerator. 

We hope we have to helped you through this article on how to select a stabilizer for fridge. It would be best if you also get good stabilizers for other electrical appliances like televisions or air conditioners as well.
