How to Make Your Fridge Last Longer
A good fridge should last 12–18 years. But poor maintenance habits can cut that lifespan significantly. These 10 practical tips will keep your fridge running efficiently and help you avoid the most common causes of premature failure.
1. Clean the Condenser Coils Every 6–12 Months
The condenser coils are either at the back or underneath your fridge. When they're coated in dust, the compressor has to work harder to dissipate heat, increasing energy use and wear. Vacuum the coils with a brush attachment every 6–12 months. This is the single most effective maintenance task for most households.
2. Check and Replace the Door Seals
Worn or cracked door seals allow cold air to escape, forcing the compressor to run more frequently. Test the seal by closing the door on a piece of paper — if the paper slides out easily without resistance, the seal needs replacement. Replace seals every 5–7 years or when you notice them failing. Door seals are inexpensive and usually available through the manufacturer or a spare parts supplier.
3. Keep the Fridge at the Right Temperature
Set your fridge between 3–5°C and your freezer at -18°C. Running the fridge colder than necessary wastes electricity and stresses the compressor. Running it warmer risks food safety.
4. Don't Overfill or Underfill the Fridge
An overfilled fridge restricts airflow, creating warm spots and making the compressor work harder. An almost empty fridge can't hold temperature as well when the door is opened. Keep the fridge reasonably well-stocked but allow air to circulate freely.
5. Keep It Away from Heat Sources
Your fridge works against the ambient temperature — the warmer its environment, the harder it works. Avoid placing it next to your oven, in direct sunlight, or against a south-facing wall (which heats up most in Sydney). Leave at least 5cm clearance on the sides and top for ventilation.
6. Let Hot Food Cool Before Putting It In
Placing hot or warm food directly in the fridge forces the compressor to run a long, intensive cycle to bring the temperature back down. Let hot dishes cool for 20–30 minutes at room temperature before refrigerating.
7. Defrost Manual-Defrost Freezers Regularly
If your fridge or chest freezer doesn't have auto-defrost, defrost it when ice buildup reaches about 1cm thick. Heavy ice buildup reduces cooling efficiency significantly and stresses the appliance.
8. Clean the Interior Regularly
Spills that get under shelves and in crevices can harbour bacteria and mould. Clean the interior with a mild bicarb soda solution (not harsh chemicals that can damage the plastic) every 1–2 months. Keep the drain hole clear.
9. Keep the Door Closed
Every time the door opens, warm air enters and the compressor has to run to restore temperature. While you can't avoid opening the door, being intentional about it (knowing what you want before you open) reduces unnecessary cycling.
10. Don't Block Vents Inside the Fridge
Cold air circulates from internal vents. Stacking food against the rear vents prevents proper air circulation, creates warm spots and makes the compressor work harder. Keep food at least 2–3cm from the back wall.
When Is It Time to Replace Rather Than Repair?
If your fridge is 12+ years old and needs a major repair (compressor replacement, sealed system failure), the cost usually exceeds the value of the appliance.
