The fridge freezer wins the award for the hardest-working kitchen appliance. Here's our super cool fridge freezer guide with answers to all your coolest questions...


What's the best temperature for your fridge freezer?

The ideal fridge temperature is between 37°F (3°C) and 40°F (5°C).

Your freezer temperature should be at 0°F (-18°C).

And it takes about 24 hours for your fridge to adjust to any changes you make.

How to take your fridge’s temperature

If you want to check how cold your fridge freezer is and you don't have a temperature readout, the easiest way is to use a thermometer:


  1. Place a thermometer in a glass of water
  2. Leave in the fridge overnight
  3. Check the temperature the first time you open the door


  1. Place the thermometer between bags of frozen vegetables
  2. Leave for about 8 hours or overnight
  3. Check the temperature reading


Is your fridge on its last legs?

Do you need a new fridge freezer? Or does your old one simply require a little TLC? Telling the difference can be hard. Look out for these signs:

  • Your food is being frozen in the fridge
  • Your food is warm when you take it out of the fridge
  • Ice is forming on the walls of your fridge
  • Ice is melting in the freezer and puddling on the floor
  • Your food keeps going off before its expiry date
  • There’s condensation on the inside or outside of the fridge


What should I do next?

Your fridge freezer might be crying out for a bit of love and attention. Try these troubleshooting tips to help cure common fridge problems:

  • Make sure the thermostat is on the right setting – it can easily be knocked
  • Double check that the plug, electrical socket and fuse box are all working properly
  • If you can’t hear a soft humming, or it’s more of a loud vibration, the compressor fan needs replacing
  • Clear the areas around the fridge so fans aren’t blocked
  • Give your freezer a thorough defrosting to remove any excess ice


Do you have a frost-free freezer?

Frost-free freezers circulate cool air to stop ice building up. If yours doesn’t seem up to the job anymore, there’s likely an issue with the compressor pump.

These look like round, black ‘tanks’ and are usually found at the back of your freezer.

If your compressor pump is working properly, it should be warm to the touch and very gently vibrating. If it’s really hot, stone cold, or not vibrating, it could have stopped working – you might need a repair.
