Is Your Fridge Working Harder Than It Needs To? Simple Refrigeration Tips That Could Save Food, Energy and Money
Most people don't think about their fridge until something goes wrong.
But your fridge is one of the hardest-working appliances in your home, running 24 hours a day, 365 days a year. A few simple checks can help it run more efficiently, keep food fresher for longer and potentially reduce energy consumption.
Here are some of the most common refrigeration questions we get asked in-store.
What Temperature Should My Fridge Be?
The ideal temperature for most fridges is around 4°C.
Many modern appliances allow you to set the temperature directly, making it easy to check and adjust. If your fridge is too warm, food may spoil more quickly. Too cold, and you could end up freezing fresh food unnecessarily.
Your freezer should typically be set to -18°C, which is the recommended temperature for safe long-term food storage.
What Do The Numbers 1-5 Mean On My Fridge?
One of the biggest misconceptions is that a higher number means a warmer fridge.
In fact, on many appliances, the higher the number, the colder the fridge becomes.
A setting of 1 is usually the warmest setting, while 5 is often the coldest.
The exact configuration varies between manufacturers, which is why checking your user manual is always worthwhile. If you're unsure, a simple fridge thermometer can quickly confirm whether your appliance is running at the correct temperature.
How To Check If Your Fridge Is Actually Cold Enough
The easiest way is to place a fridge thermometer in the middle shelf overnight.
Check the temperature first thing in the morning before the door has been opened multiple times. This gives the most accurate indication of the fridge's operating temperature.
Ideally, you should see a reading between 2°C and 6°C, with around 4°C being the sweet spot for most households.
Why Does My Fridge Struggle During Hot Weather?
When temperatures rise, your fridge has to work much harder to maintain the correct internal temperature.
Every time the door is opened, warm air enters and the appliance has to remove that heat again. During heatwaves, this process becomes even more demanding.
That's why it's particularly important to avoid overloading your fridge, minimise unnecessary door openings and allow hot food to cool before placing it inside.
Three Common Fridge Mistakes During A Heatwave
1. Blocking Ventilation
Fridges need space around them to release heat.
If ventilation gaps are blocked by boxes, appliances or cabinetry, the appliance can struggle to cool effectively.
2. Putting Hot Food Straight In
While it may seem convenient, placing hot food directly into the fridge forces the appliance to work harder and can temporarily raise the temperature of surrounding foods.
Allow food to cool first before refrigerating.
3. Constant Door Opening
Standing with the fridge door open while deciding what to eat allows significant amounts of warm air inside.
During hot weather, even small habits like this can make a noticeable difference.
Don't Forget About The Condenser Coils
Many homeowners don't realise that fridges require occasional maintenance.
Dust can build up on condenser coils, making it harder for the appliance to release heat efficiently. This can increase energy consumption and put additional strain on components.
Some appliances have easily accessible external coils, while others are enclosed. If accessible, a careful clean can help maintain performance.
Check Your Door Seals
Damaged or dirty door seals can allow cold air to escape and warm air to enter.
Look for:
- Cracks or splits
- Areas where the seal isn't sitting flush
- Mould or dirt build-up
A quick clean can often improve the seal, while damaged seals should be replaced to maintain efficiency.
Small Checks, Big Benefits
Modern refrigeration is incredibly reliable, but a little maintenance goes a long way.
Checking temperatures, keeping ventilation clear, cleaning seals and understanding your appliance's controls can all help improve performance and extend the life of your fridge.
