How Much Electricity Does a Refrigerator Use?

Refrigerators are a staple in modern households, playing a crucial role in food preservation by maintaining a temperature below the ambient level to inhibit bacterial growth. The concept of refrigeration has evolved tremendously since its inception, leading to more efficient and environmentally friendly models. Understanding the operation costs and energy consumption of your refrigerator can lead to significant savings and reduced environmental impact. You will learn how much it costs to run a refrigerator, how much electricity a refrigerator uses, and how to reduce electricity use.

Let’s dive in more and see what you can do to lower the amount of electricity your refrigerator uses.

How Much Electricity Does a Refrigerator Use?

A typical refrigerator can use anywhere from 100 to 800 kilowatt-hours (kWh) annually, with larger and older models often at the higher end of this range. Energy Star-rated refrigerators are generally more efficient and consume less electricity.

How Much Does It Cost to Run a Refrigerator?

The cost to run a refrigerator varies based on factors such as the model’s efficiency, the cost of electricity in your area, and how well the appliance is maintained. On average, refrigerators account for about 8-10% of a household’s energy bill.

How to Check Energy Usage of a Refrigerator

To check your refrigerator’s energy usage, you can refer to the Energy Guide label, use a kill-a-watt meter to measure actual consumption or analyze your household’s electricity bill to estimate the refrigerator’s share. Additional ways to check energy usage of a refrigerator are Installing a home energy monitor system and conducting a home energy audit.

How Many Volts and Amps Does a Refrigerator Use?

A standard home refrigerator usually operates on 120 volts and may draw between 3 to 5 amps while running. The starting amperage can be considerably higher before settling to its running current.

Coils on a refrigerator need to be cleaned so that it can use electricity efficiently.

How to Reduce Electricity Consumption

All households can learn how to reduce electricity consumption with their refrigerator. This can be done by:

  • Setting your refrigerator at optimal temperatures (35-38°F for the fridge and 0°F for the freezer).
  • Ensuring that the doors are properly sealed.
  • Keeping the refrigerator full but not overcrowded.
  • Regularly cleaning the condenser coils.
  • Upgrading to an Energy Star-certified model.
  • Adjusting the power saver switch if available.
  • Minimizing door openings.

How Do Solar Panels Help?

Many people talk about adding solar panels to their home. Solar panels can offset the electricity consumed by a refrigerator, directly powering the appliance during daylight and storing excess energy in batteries for nighttime use, which could potentially lower electricity bills significantly. If you are interested in this, it is important to contact a professional to find out more.

How Much Electricity Do Other Appliances Use?

Other major appliances also contribute significantly to energy bills. For example, air conditioners, electric furnaces, and water heaters can be substantial energy consumers, each using hundreds to thousands of kWh per year.

Defrosting a refrigerator is a good way to keep the refrigerator going as well as extend its lifespan.

Maintenance Tips for Refrigerators

Maintaining your refrigerator is essential to ensure it operates efficiently and to extend its lifespan. Here are some specific maintenance tips:

Regular Defrosting

  • Manual Defrost: If your refrigerator is not frost-free, regular defrosting is necessary to prevent ice buildup, which can impair the appliance’s cooling efficiency. Turn off the unit and allow the ice to melt before turning it back on.
  • Automatic Defrost: For frost-free models, ensure that the defrosting mechanism is functioning correctly. Listen for the defrost timer and check if the defrost heater is working.

Checking and Replacing Door Seals

  • Inspect Seals: Check the door seals (gaskets) for any signs of wear or damage. Loose or cracked seals can let warm air in, causing your refrigerator to work harder.
  • Clean Seals: Use a mild detergent to clean the seals regularly, removing any food residue or grime that could compromise the seal.
  • Replace if Necessary: If seals are damaged, replace them promptly to maintain optimal efficiency. This is usually a straightforward process that can be done without professional help.

Cleaning the Condenser Coils

  • Locate Coils: Find the condenser coils; they may be located at the back or beneath the refrigerator.
  • Unplug Refrigerator: Always unplug the refrigerator before starting any maintenance work for safety.
  • Remove Dust and Debris: Use a coil brush or vacuum cleaner with a brush attachment to remove dust, pet hair, and other debris from the coils.
  • Frequency: Clean the coils at least twice a year, or more often if you have pets or if the refrigerator is in a dusty area.

Refrigerator Maintenance

Now that you know about the amount of electricity a refrigerator uses, it is important to know about other maintenance and issues you may need to tackle. One of those is resetting a filter light on a Samsung refrigerator. You will know that it is time for a reset when you see the light on. It means that it is time to change out the filter. There are step-by-step directions that you need to follow and then you can reset the light.

Another area is troubleshooting your electrical system. Sometimes this involves testing an outlet with a multimeter so you can find out if it is the outlet or the refrigerator or other appliance that isn’t working. This is always a great first step before you call a professional and will save you money as well.

Lastly, you may need to reset your Samsung refrigerator. Often this happens if there is an ice maker that isn’t working, power outage, water filter issue, or error codes. When you reset it, it should help with whatever is causing the problem. Depending what the issue is, there are steps you will need to follow.

When You Need a Professional

Consider calling a professional if your refrigerator shows significant deviations from normal operating sounds. Also, if it has visible frost buildup or excessive condensation. Lastly, if you experience inconsistent cooling despite trouble-free settings.

Additionally, professional assistance is recommended for installing a home energy monitor or when conducting a comprehensive home energy audit.


Understanding the intricacies of refrigerator energy usage is beneficial both economically and ecologically. By implementing energy-efficient practices and considering renewable energy sources like solar panels, homeowners can reduce their carbon footprint while enjoying monetary savings. Regular maintenance and being mindful of the signs that warrant professional help can extend the lifespan of your refrigerator and ensure it runs efficiently.

While you are taking a look at the electricity usage of your refrigerator, it is a good time to have a home inspection. Call House Inspection Associates to conduct a full home inspection in the Virginia, D.C., and Maryland areas.
