What Affects Fridge Power Use

Many factors will affect the more energy efficient consumption of your freezer or fridge. These factors include:

  • Type. Commercial display fridges can be ten times more efficient than home bar fridges.
  • Size. Anything larger, like side-by-side fridges, consumes more electricity.
  • Observe the location. The fridge will consume more power if it is located in a warm place or poorly ventilated.
  • Season. As the ambient temperature rises, all refrigerators consume more power in summer than winter.
  • Use. The compressor will work harder to maintain cool temperatures if the fridge door is frequently opened or left open. An empty fridge will require more cooling power than one that is adequately stocked. This is because the compressor has to replace more of the ‘cool’ air with warm air each time it is opened.
  • Temperature setting point. The fridge may be set to factory temperature, which is lower than what you need in your home.
  • Age. Old fridges are less efficient than high-star rated refrigerators.
  • Good condition. Your fridge will not work as efficiently if the seals are damaged.


It may surprise you to learn that, while refrigerators seem to consume a lot of power because they are always on, they use less than other main electric appliances like an air conditioner or water heater.

Payless Power answers the question, How many watts does a refrigerator use? This will help you determine how much the fridge contributes to your monthly cost bills and show you ways to save energy efficiency.

Calculating Average Wattage for Refrigerators

Calculating Average Wattage for Refrigerators

For an average running wattage calculator to determine the average wattage of your refrigerator, multiply volts by amps.

These numbers will be referenced on a sticker located on the inside of the fridge.

Older refrigerators use 115V and 7A, which can be multiplied to get 805 Watts. Conventional refrigerators typically have a wattage range of 800-1200 watt-hours/day and a running wattage around 150-watt hours/day.

Refrigerators can be reactive devices and require more power to start. They have an electric motor but consume significantly less power to run while they are on.

There are also internal fans that can run intermittently and a defrost cycle that requires power. Many factors affect the running wattage and starting wattage of refrigerators, as you can see.

Monthly Cost of a Refrigerator

Calculate the cost of each kWh that your refrigerator consumes to calculate how much it contributes to your monthly electricity usage bill. Since refrigerators are constantly on and off, the U.S. Department of energy consumption assumes that there will be eight hours of operation per day.

To get 6,440 watts daily, multiply the refrigerator’s 805 watts requirement by 8 hours. Divide this amount by 1,000 to get 6.44 Kilowatt-hours.

Americans are charged 12 cents per Kilowatt, which means that your fridge might cost you $23.10 per month or 77c per day.

Four Ways to Cut Fridge Power Consumption

1. Make sure fridges have good ventilation. Many fridges are stuffed between wall cabinets, which can increase the fridge’s power consumption.

2. Combine the number of fridges currently in use. You can empty a garage fridge that is only partially full and turn it off.

3. Timer switches can be used on bar fridges and drinks fridges. By doing this, fridges that don’t contain perishable foods are only turned on when needed.

4. Adjust the temperature. Particularly freezers are often too cold. To check your settings and make adjustments, use a thermometer. Domestic refrigeration is safe and sufficient at 4@C in the fridge and -15@C in the freezer.

Using A Generator To Run Your Refrigerator

A generator may be a good option if you live in an area with frequent power outages or have lost fridge power consumption because of a storm. Before you turn on the generator, these are some things you should know.

What size generator do I need to run a refrigerator?

As mentioned above, it is important to determine how many watts your refrigerator consumes. The motor requires more fridge power consumption to start the generator than it needs to run. Your 750-watt refrigerator may have a starting wattage of 1,200 Watts. A 1,500-watt generator could be used to power your fridge. Check the manual to confirm the startup wattage.

Will a 5,000-watt generator run a refrigerator?

A generator of 5,000 watts should be able to provide enough power to power a refrigerator. The average home refrigerator requires around 2,000 watts to start.

Can a 2,000-watt generator run a refrigerator?

A 2,000-watt generator will power most home refrigerators, depending on how big your fridge is. To avoid overloading the generator, make sure you check the wattage and start the wattage of your refrigerator before starting.

Can a generator damage a refrigerator?

A generator can damage refrigerators, but it isn’t usually a sensitive appliance. If your generator’s starting wattage is too low, your fridge may overheat.



Energy Star claims that certified refrigerators consume 20% less energy than traditional models. Are you not ready to commit to a major upgrade? Payless Power offers some low-cost and free tips to optimize your appliance’s energy efficiency.

1. Place it Away From the Heat.

Your fridge should be kept in a cool place away from heat sources such as the sun or oven. The hot air around refrigerators is already hot.

2. Move with Speed.

Avoid leaving the fridge door open to reduce energy waste. When the door is open, the compressor activates and increases the power consumption of the fridge. Try to grab the items you need immediately from the fridge, and then close the door as quickly as possible.

3. Set the Right Temperature.

A fridge or freezer set at very low temperatures can lead to a lot of energy waste. You should set the thermostats at the ideal temperature for your fridge or freezer, which is 37 degrees Fahrenheit.

4. Clean it Regularly.

You can do yourself a favor by adding a routine cleaning to your fridge once every three months. You can lift the fridge from the wall to dust the coils and back. The kick plate on top of the fridge can be removed and washed. Your fridge will require less energy to operate if it can breathe easily.

5. Cool Food Only, and Lots of It.

To save your fridge from burning your compressor, cool your leftovers. Your fridge should only be used for cold or room temperature food.

To ensure that your freezer doesn’t need to work extra to cool off empty spaces, keep it at least three-quarters full.

6. Willing to Spend a Little? Replace the Gaskets.

Your fridge mustn’t leak cold air. This could be a costly waste of energy. It is worth replacing rubber gaskets in your freezer and fridge if they are not keeping cold air in.


Can a refrigerator run up an electric bill?

Refrigerators consume a lot of electricity costs. They are the largest energy consumers in most homes after cooling, heating, and hot water systems. There are many ways to save more energy, even if your fridge is used a lot. You can save a lot of money by using your fridge efficiently.
