How many watts does a refrigerator use?

Updated: Dec 6, 2023

A refrigerator is an essential appliance in most households, keeping food and drinks fresh and safe for consumption. However, many people may wonder how much energy their refrigerator consumes and how much it costs to run it. In this blog, we will answer the question: how many watts does a refrigerator use?

The location of a compressor in a refrigerator.  Regular cleaning of the refrigerator condenser is important to reduce energy consumption.

Regular cleaning of refrigerator coils is important to reduce energy consumption.


Typically, an average home refrigerator in Puerto Rico uses around 300 to 1000 watts of electricity with most models using 3 to 7 amps and 120 volts.


For example, if a refrigerator runs on 120 volts and uses 3 amps this means its wattage is 360 watts. It’s good to mention that in reality, a refrigerator has a much lower running wattage because it cycles on and of throughout the day. To estimate the actual energy usage of your fridge, a good rule of thumb to follow is to divide its wattage by 3. So in the earlier example, a 360-watt generator will only use around 120W.

W = 120 x 3 360W/3 = 120W


How do I calculate my refrigerator’s power consumption?

If you want to figure out how much it costs to run your refrigerator, refer to the sticker inside your fridge to get the volts and amps then compute the wattage.

Using the example above, the running wattage for the refrigerator is 120W - multiply it by the hours of the day (24), so you get 2,880 watts. Divide 2,880 by 1,000 to convert to kWh and you’ll get 2.88 kWh.

120 W x 24 hours = 2,880 W

2,880 W / 1,000 W = 2.88 kWh


However, the refrigerator's wattage is usually rated when the compressor is on. In the real life, the refrigerator's compressor is not always on. The compressor may only kick on 1 minute for every several minutes depending on the usage. Assuming the compressor is on 1 minute for every 5 minutes, the power consumption will be reduced to 1/5 (1 minute / 5 minutes).


It's important to note that the energy consumption of your refrigerator can be affected by a number of factors, including the temperature of your home, how often you open and close the refrigerator door, and the age and condition of the appliance. In addition, if your refrigerator is not energy efficient, it can use significantly more electricity than newer models.


"Did you know that the energy consumption of your refrigerator varies depending on where it's located? If you have the possibility to move it, avoid having it near heat sources such as the stove or windows." - Wilfredo, SERVICIOS RUSH Technician

To reduce the energy consumption of your refrigerator, you can take several steps, including:

  • Keeping the refrigerator well-stocked, as a full refrigerator requires less energy to cool than an empty one.

  • Ensuring that the refrigerator is not located near a heat source, such as a stove or direct sunlight.

  • Cleaning the refrigerator's coils regularly to ensure that they are not clogged with dust and debris.

  • If possible, upgrade to a newer, more energy-efficient refrigerator model (ENERGY STAR), when your refrigerator is old and you want to save energy.


In conclusion, the average refrigerator in Puerto Rico uses around 725 watts of electricity per day, although this can vary depending on several factors.


To get a more accurate estimate of your refrigerator's energy consumption, check the energy label on the appliance, and take steps to reduce your energy usage and save money on your electricity bills.



What about maintaining your refrigeration system by cleaning the coils of your refrigerator?

Cleaning the coils of a refrigerator is important to reduce energy consumption because when they are clogged with dust and debris, the compressor has to work harder to maintain the set temperature. This increased workload leads to higher energy consumption and can cause the compressor to fail prematurely. By keeping the coils clean, the compressor can operate more efficiently and use less energy to keep your food cold.


Regular refrigeration maintenance is an investment that can save you money in the long run. By avoiding costly repairs and improving the efficiency of your appliance, you'll enjoy lower energy bills, a more reliable appliance, and peace of mind knowing that your food is being stored safely.
