How to Save Electricity with Your Fridge and Freezer

Here’s what usually helps it run easier:

• Keep it out of direct sunlight from windows, especially the afternoon western sun we get in so many Australian homes
• Give it plenty of space away from the oven, cooktop, dishwasher, or any other heat source
• Make sure there’s good airflow all around it
•  Leave the gaps at the sides and back that the manufacturer recommends

In lots of modern open-plan Australian homes, it’s easy for the fridge to end up near a heat source without you realising. Have a proper look at your kitchen layout. Check the manual for the recommended gaps, most makers want at least a few centimetres clear so the heat can escape. Get this right and the motor doesn’t have to run as often.

Use Recommended Temperature Settings

Correct temperature settings help keep food safe while avoiding unnecessary energy use.

As a general guide:

If settings are colder than necessary, the appliance may use more electricity without providing additional everyday benefits.

Using a fridge thermometer can help you check that temperatures remain within a suitable range, particularly during warmer months.

Keep the Door Closed as Much as Possible

Every time the fridge or freezer door opens, warm air enters and the appliance must work to cool the interior again.

Simple ways to reduce door opening time include:

• Decide what you need before opening the door
• Return items promptly after use
• Avoid leaving the door open while unpacking groceries
• Group commonly used items together for quick access

These habits can be especially helpful in busy households where doors may be opened frequently throughout the day.

Check Door Seals Regularly

Door seals, also known as gaskets, play an important role in keeping cold air inside. If seals are loose, cracked, or dirty, cool air can escape and the appliance may need to run more often.

Signs a seal may need attention include:

• The door not closing firmly
• Visible cracks or wear
• Moisture forming around the edge
• The motor cycling more often than usual

To help maintain seals:

• Wipe them clean with mild soapy water
• Remove crumbs or sticky residue
• Check for damage every few months

If seals are worn, replacing them may help improve efficiency.

Avoid Overfilling or Underfilling

A well-organised fridge or freezer can support better airflow. When packed too tightly, cold air may not circulate evenly. When almost empty, some freezers may lose cool air more quickly when opened.

Aim for a practical balance:

• Keep items organised with space between them where possible
• Avoid blocking vents inside the appliance
• Store freezer items neatly rather than piling them tightly

This can help maintain steady temperatures and improve performance.

Let Hot Food Cool First

Never put steaming hot food straight in. It makes the temperature inside jump up and forces the fridge to work really hard.

Instead:

• Allow cooked food to cool slightly first
• Use shallow containers for faster cooling
• Refrigerate food within safe timeframes once no longer hot

This supports both food safety and appliance efficiency.

Clean Coils and Vents

Dust build-up on condenser coils or ventilation areas can reduce efficiency. When airflow is restricted, the appliance may need to work harder to remove heat.

Depending on the model, coils may be located at the rear or underneath.

Basic maintenance may include:

• Unplugging the appliance first
• Carefully vacuuming dust from accessible coils
• Wiping vents free of dust
•  Follow what your manual says for your model

‍

It’s not a hard job and it helps the whole thing run smoother and use less electricity.

Defrost When Needed

For manual-defrost freezers, thick ice build-up is bad news.

When you see a decent layer of frost:

• Empty it out
• Let it defrost completely
• Clean and dry the inside properly
• Turn it back on

Frost-free models do this job themselves, but keeping the seals clean still helps a lot.

Use Energy Rating Labels When Comparing Appliances

If you are reviewing or replacing an appliance, Australia’s official Energy Rating Labels can help compare electricity use between models.

These labels typically show:

• A star rating
• Estimated annual energy consumption
• Brand and model details

Higher star ratings generally indicate stronger energy efficiency. Comparing similar-sized appliances can provide a clearer guide when choosing between options.

Build Everyday Energy-Saving Habits

The small stuff you do without thinking eventually becomes normal:

• Keep the fridge organised, so you’re not searching and holding the door open
• Label your leftovers with dates
• Throw out old stuff regularly to stop clutter
• Always make sure the door is properly shut
• Don’t keep changing the temperature dial up and down

Consistent habits can support efficient operation without changing your normal routine too much.

Seasonal Considerations in Australia

Our summers can be brutal on these appliances, especially during those 35+ degree days we get in so many parts of the country.

In the hotter months, try to:

• Check the door seals more often
• Keep door openings short and purposeful
• Keep airflow around the appliance clear
• Confirm temperatures remain in the recommended range

These steps can help your fridge and freezer perform more effectively in warmer conditions.

Final Thoughts

Saving electricity with your fridge and freezer often comes down to simple maintenance and smart daily habits. By checking placement, using suitable temperature settings, maintaining door seals, and keeping airflow clear, you can help these appliances run efficiently throughout the year.
