Check the temperature
To check if your fridge is operating at the correct temperature you need to purchase a thermometer from your local homeware store and place it in the fridge. When you do this you might get some surprises. The temperature inside your fridge will vary several degrees as the fridge goes through its cycle. It will also vary markedly from one section to another.
Where to place your thermometer
The door is usually the warmest part and the top shelf is often the warmest shelf. We suggest you place your thermometer below the top shelf and towards the door where you can read it easily to give a general indication of the fridge temperature.
Keep it at 4 to 5°C
If the thermometer shows your fridge is higher than five degrees, adjust the fridge setting to lower the temperature. The crispers for fruit and vegetables will usually be slightly warmer so that the fruit and vegetables don’t freeze. You might have to adjust the fridge a few times to get it right, but ideally, you want the main compartment to spend most of its time around 4 to 5°C. Check that food looks and feels frozen to be sure your freezer is functioning correctly or use a thermometer if you have one covering this range. Partially frozen food will have a shorter shelf life.
