What temperature should your fridge be?



The fridge freezer wins the award for the hardest-working kitchen appliance. Make sure you have it set to an optimum temperature to keep your food fresh and your fridge working.

Your fridge freezer works hard to keep your food cool. It's on-the-go every hour of the day and night and doesn't need a huge amount of attention to keep working. Here are some hints and tips to keep it at its best.

  • 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) 
  • Use a fridge thermometer to check the temperature if you are not sure the thermostat is working properly
  • It generally takes about 24 hours for any changes you make to the fridge's temperature to take effect

Getting accurate fridge and freezer temperature readings:

If you want to check how cold your fridge freezer is using a fridge thermometer for any reason, try these tips:

  • Fridge: Fill a glass with water and pop the thermometer in. Leave this in the fridge overnight and check the temperature the first time you open the door
  • Freezer: Put the thermometer down between a couple of bags of frozen vegetables. Leave for about eight hours then check the temperature

Is something wrong with your fridge freezer?

Here are a few things that could indicate your fridge freezer isn't working properly:

  • Is your food freezing in the fridge?
  • When you take food out of the fridge, does it feel warm?
  • Is ice forming on the walls of the fridge?
  • Can you see ice melting in the freezer section?
  • Has any food gone off before the expiration date?
  • Is there condensation on the inside or outside of the fridge?

Before you book a repair:

Make these simple checks before phoning for a repair:

  • Make sure the thermostat hasn't accidentally been changed to the wrong setting
  • Double check there's not an issue with the plug or electrical socket, and check the fuse box to make sure it's not flipped
  • You should be able to hear a soft humming from the fridge - this is the compressor fan. If it's totally silent or making enough noise to disturb the neighbours, it might need replacing 
  • Make sure the area around the fridge isn't too cluttered. This can block up the fans or vents and stop them working properly
  • Give the fridge and freezer a thorough defrosting to remove any excess ice blocking the vents

If you have a "frost free" freezer which appears to have stopped working, you may have an issue with the compressor pump.

These pumps are normally around the back of the freezer and look like round, black "tanks".  It should be warm to the touch and be very gently vibrating. If it's really hot, cold or isn't vibrating, it might have stopped working. 

Always refer to the manufacturer's manual for specific details.
