10 Simple Habits That Keep Your Fridge Running Efficiently
10 Simple Habits That Keep Your Fridge Running Efficiently.
Your fridge is one of the hardest-working appliances in your home, running 24/7 to keep your food fresh and safe. But did you know that small habits can make a huge difference in how efficiently it operates — and how much energy it consumes?
For Aussie homeowners looking to save on electricity bills and extend the life of their appliances, maintaining your fridge properly is a must. Let’s explore 10 simple habits that keep your fridge running efficiently all year round.
1. Keep the Door Closed as Much as Possible
It might sound obvious, but this is one of the biggest energy drains in households. Every time you open your fridge door, cool air escapes and warm air enters, forcing your fridge to work harder to restore the temperature.
Get into the habit of thinking before opening — know what you’re reaching for. Encourage family members (especially kids) to do the same. You’ll reduce unnecessary cooling cycles, saving both energy and wear on your fridge motor.
2. Check and Clean the Door Seals Regularly
Those rubber seals around your fridge and freezer doors (called gaskets) are critical to keeping the cold air in. Over time, they can collect grime, loosen, or crack, letting precious cold air escape.
Do a quick test: close the door on a piece of paper. If it slides out easily, your seals may need replacing. Wipe them down monthly with warm soapy water to remove food residue and ensure they remain flexible and airtight.
3. Keep It at the Right Temperature
Setting your fridge too cold wastes energy without keeping food fresher. The ideal fridge temperature is 3°C to 5°C, and your freezer should be around -18°C.
Many Aussie households unknowingly run their fridges colder than necessary. If you notice ice forming or milk freezing in the back, it’s time to turn it up slightly. Using a simple fridge thermometer can help keep things in check.
4. Don’t Overfill or Underfill
A fridge that’s packed to the brim restricts airflow, making it harder for cool air to circulate evenly. On the other hand, an empty fridge doesn’t retain cold well because there’s less mass to help stabilize the temperature.
Aim for a balanced middle ground. Keep enough food and drinks inside to maintain coolness, but avoid overloading shelves and blocking vents. Here is a link to a blog which talks about how to your organise your fridge like an expert.
5. Clean the Coils at the Back or Bottom
Most modern fridges have condenser coils at the back or underneath. These coils are responsible for releasing heat, and when they get dusty, your fridge has to work overtime to keep things cool.
Every six months, pull your fridge slightly away from the wall and gently vacuum or brush off the coils. This simple maintenance task can improve energy efficiency by up to 30% and extend your fridge’s lifespan.
6. Allow Food to Cool Before Storing It
Putting hot leftovers straight into the fridge raises the internal temperature and forces the compressor to work harder to cool everything back down.
Let hot food sit out for about 30 minutes (until it’s room temperature) before refrigerating. This habit keeps your fridge running efficiently while maintaining safe food storage practices.
7. Give It Space to Breathe
Your fridge needs proper ventilation to release heat effectively. If it’s too close to the wall, cabinet, or other appliances, heat can get trapped around it, causing it to overheat and consume more power.
Make sure there’s at least 5–10 cm of space behind and around your fridge. This allows airflow and helps the cooling system perform optimally, especially during Australia’s hot summer months.
8. Defrost Regularly (If It’s Not Frost-Free)
If you have an older fridge model without automatic defrosting, frost buildup can become a major energy waster. A thick layer of ice reduces the freezer’s ability to transfer cold efficiently.
When you notice frost exceeding 5mm in thickness, it’s time to defrost. Turn off the appliance, remove the contents, and allow it to thaw naturally. Once done, wipe it clean and restart — your fridge will thank you.
9. Keep It Out of Direct Sunlight and Away from Heat Sources
Location matters. If your fridge is placed near a window, oven, or dishwasher, it’s constantly exposed to heat, making it work harder to stay cool.
Whenever possible, position your fridge in a shaded area of the kitchen, away from heat-producing appliances. If relocating it isn’t an option, consider using window blinds or curtains to block out direct sunlight during peak hours.
10. Schedule Regular Professional Check-Ups
Just like your car, your fridge benefits from professional maintenance. Electricians and appliance specialists can inspect wiring, thermostats, and energy performance to ensure everything runs safely and efficiently.
Over time, electrical wear and tear, faulty plugs, or poor power connections can reduce your fridge’s performance or even pose safety hazards. Having it checked as part of your home’s electrical maintenance plan can help you catch small issues before they turn into costly repairs.
Bonus Tip: Keep It Organised!
A well-organised fridge isn’t just visually pleasing — it helps maintain even airflow and reduces the time the door stays open. Group similar items together, label leftovers, and avoid crowding the back of shelves.
You’ll spend less time rummaging and more time saving energy.
