How Many Watts Does a Samsung Refrigerator Use?

A refrigerator is a very common appliance in households. It is also very essential in order to store food which requires temperature control. Refrigerators are also one of the most power hungry appliances in a household.

Watts usage for a samsung refrigerator

The watt usage of a Samsung refrigerator varies vastly depending on the size of it. A small fridge can take up to 400 watts while a large refrigerator can pull as much as 780 watts. A side by side Samsung refrigerator would take up more than 800 watts.

As refrigerators can vary vastly in size, it is important to know that an average Samsung refrigerator can take anywhere from a hundred to four hundred watts.

On the other hand, an industrial refrigerator or a Samsung side by side door refrigerator could take about double or more than double the peak wattage of a regular refrigerator.

The wattage of a refrigerator also varies within models as they may have a different construction.

Per hour:

On an hourly basis, a regular Samsung refrigerator would be taking up 0.15 kilowatt-hour.

One the other hand, a side by side refrigerator would take up roughly 0.8 kilowatt-hours per hour. A side by side refrigerator is much more power hungry than a regular refrigerator.

This is all estimated after taking into account the power cycle of the refrigerator. A refrigerator does not necessarily run at full capacity throughout the whole 24 hour period. A refrigerator realistically runs for 8 hours throughout a whole day.

Per day:

If we run a Samsung refrigerator a full day, it could take anywhere from between one to four kilowatt-hours. A side by side refrigerator would take roughly 1.2 kilowatt-hours to run a full day (8 hours) considering a 33% power cycle.

However if we estimate that the refrigerator is running a full twenty four hour shift, a regular Samsung refrigerator would draw in about 3.6 kilowatt-hours. On the other hand, a side by side refrigerator would take up 19.5 kilowatt-hours.

Per month:

Over a whole month considering an 8 hour power cycle, a regular refrigerator would take up roughly 36 kilowatt-hours a month if we consider 30 days in a month. A side by side refrigerator would take roughly 192 kilowatt-hours a month.

If we consider a 24 hour power cycle, a regular refrigerator would take about 108 kilowatt-hours while a side by side refrigerator would need roughly 576 watt-hours.


A refrigerator does not always run at its peak wattage and can vary tremendously. Although it does not always run at peak, the startup wattage of a refrigerator can be many times higher than its peak wattage.

The starting wattage of a refrigerator is roughly four times its peak wattage. If we are to use a regular Samsung refrigerator of 400 watts, it would need a startup wattage of 1600 watts.

A side by side refrigerator requiring over 800 watts to run would need a startup wattage of over 3200 watts.

How big of a generator do I need to run my Samsung refrigerator?

When choosing a generator to run your Samsung refrigerator, a lot of factors need to be put into place. You could choose a generator which is rated slightly higher than the peak wattage of your Samsung refrigerator, but it would not run it.

We need to take into consideration the startup wattage of your Samsung refrigerator. Your refrigerator would require power many times higher than the peak wattage in order to startup in the first place.

For example if we were to run a Samsung refrigerator with a peak wattage of 700 watts, it would need a startup wattage of 2800 watts (four times the peak wattage). That in total would be about 3500 watts.

Hence, in order to run that Samsung refrigerator, you would require a generator rated for over 3500 watts taking into account power surges. Anything less, and your generator would not run your Samsung refrigerator.

How much does it cost to run a fridge per month?

The cost to run a fridge per month may vary according to types and brands. Let’s get to know how different Samsung fridges cost.

Samsung French door:

A Samsung French door, or side by side refrigerator is known to be more power hungry than your average refrigerator. As we know they need roughly 800 watts and above to run.

The daily cost of a Samsung French door refrigerator would be about 0.29 dollars or more.

While monthly, it would set you back about 8.67 dollars or more. Finally, the annual cost to run a Samsung French door refrigerator would be around 106 dollars or more.

Note that these costs are based on the fact that we are considering the peak wattage to be of 800 watts and above.

Samsung inverter fridge:

A Samsung inverter fridge costs on average 13% less to run. In that case a regular refrigerator would cost around 3.77 dollars to run on a monthly basis.

All of this is estimated considering that the peak wattage of your refrigerator is 400 watts.

How can I make my Samsung refrigerator use less energy?

As it can get costly to run refrigerators, many may seek ways in order to save energy and in turn money. Fortunately, there are many ways in order to keep the costs and energy usage of a refrigerator down.

Keeping heat sources away from your refrigerator:

Fridges which are close to heat sources require more power to run as it needs to work harder to keep its insides cooler. Since it requires more energy, it also requires more money.

Keep your refrigerator away from heat sources for example: radiators, microwaves, rice cookers.

Keeping space around the fridge:

A refrigerator requires at least one inch of space all around it in order for good airflow and better cooling. Do refrain from stacking things on top and around your refrigerator.

Avoid placing warm food in the refrigerator:

Putting warm food in your refrigerator would require it to work harder to keep the inside temperature cooler, hence requiring more power and increasing costs. Wait for your food to cool down before placing it in the refrigerator.

Keeping the coils clean:

The coils at the back of your refrigerator are responsible for transferring heat away from the fridge. Not keeping the clean would limit how much heat it can transfer away thus requiring more power and more money.

How to estimate your Samsung refrigerator’s power consumption?

To estimate the power consumptions, you need to follow the proper steps. Let’s get to know it.

  • Buy a well rated kill-a-watt meter from a reputed hardware store, you can also find them in stores like BestBuy, Amazon, and Micro Center.
  • Plug in the plug of your refrigerator into the kill-a-watt meter and make sure that they are connected properly together.
  • Plug the whole thing into the main socket and wiggle to check if the whole thing is sturdy enough.
  • Observe how much wattage is being drawn from the wall. The reading will be in real time and they are expected to vary from one minute to the other.
  • Wait for about three to seven days in order to get the exact power consumption of your given refrigerator as the readings can vary and you may need to create an average.
  • After taking the reading from the kill-a-watt meter in order to make sure that the readings are viable, we will calculate the power consumption of your refrigerator manually.
  • Look for a sticker on your refrigerator which says ‘BEE star rating’. After that, look for the annual consumption unit under it.
  • Estimate the power consumption of your refrigerator which will be written in units, 1000 watts of electricity is known as 1 unit of power.
  • Once you find out the power consumption of your refrigerator in units, use a calculator to finally estimate the monthly power consumption.
  • Divide your power consumption unit by 12 in order to get the monthly unit of power consumption.
  • If you get your monthly consumption in watts, you can divide it by 1000 in order to get your answer in kilowatts. If you want your answer to be the other way round, you will have to multiply your answer by 1000.

Final Thoughts

Samsung refrigerators require a wide variety of wattage in order to run. There are many variables like peak wattage, startup wattage, and running wattage that need to be taken into the factor. All of those factors vary from different kinds of Samsung refrigerators. But on average its 800 watts.
