The fridge freezer wins the award for the hardest-working kitchen appliance. And if your fridge is working at its best it means it’ll use less energy and there will be much less food waste too. But what do you need to give your fridge a much-needed MOT? Here's our super cool fridge freezer guide with answers to all your questions...

What is the correct fridge temperature?

The ideal fridge temperature is between 37°F (3°C) and 40°F (5°C). And your freezer temperature should be at 0°F (-18°C).

But before you touch those dials, just be aware that it takes 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 good old-fashioned 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

Common fridge temperature problems

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:

  • My fridge is warm

  • Your fridge is freezing food on lowest setting

  • Your food is warm when you take it out of the fridge

  • Ice is forming in the back 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?

Just because your fridge freezer is having trouble, it doesn’t mean getting rid of it. Try these troubleshooting tips to help cure some common fridge problems:

  • Make sure the thermostat is on the right setting – it’s easy to adjust it by accident when you’re loading up your fridge

  • 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 may need 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.
