Kit Guide: What temperature should your fridge and freezer be?

squiggleboldXL

It’s important to make sure your fridge and freezer are set to the right temperature.

If your fridge is too warm, food won’t last as long as it should, while keeping it too cold can cause ice to build up and ruin fresh food.

Your freezer getting too cold isn’t really an issue, but if the temperature is only set a few degrees below zero, the temperature can rapidly rise when you open the door, which can prematurely defrost your food and ruin it.

The right temperature

The temperatures we recommend in this guide will keep your food safe and preserved for longer, and will help to prevent any unwanted ice build-up.

For fridges

Make sure the temperature is set between 3 - 5°C

For freezers

Make sure the temperature is set below 18°C

Checking the temperature

Even if your fridge or freezer doesn’t have a digital display to tell you the exact temperature, you can still find it out. You'll need a fridge or freezer thermometer.

For fridges

Just pop the thermometer in the a glass of room temperature water and leave it in the fridge overnight. The water will cool to the same temperature in the cavity and give you an accurate temperature reading.

For freezers

Do the same as the fridge, but replace the water with spirit alcohol (like vodka). If you don’t want to use alcohol, you can put the thermometer between two bags of food and check it after around eight hours.
