You just bought some milk and you want to make sure it lasts in the fridge but the temperature dial doesn’t seem to have any indicators. Fridge freezer temperature settings are rarely mentioned in the manual and often remain a mystery. So, if the numbers go from 1 to 5, then which is the coldest? Are these degrees or frosting power? On every fridge the rules for the coldest settings are always the following:
The numbers on the fridge’s temperature dial indicate refrigerant power. The higher the number goes the colder the fridge will maintain.
With this out of the way, it should be noted that a lower fridge temperature does not equal better food storage.
What number should a safe and efficient fridge be kept on?
First some clarifications:
- A refrigerator’s temperature usually ranges from 0.5 to 4 degrees Celsius.
- It also matters on which shelf the food is stored. In most cases the higher you go the colder it gets.
If you’re always storing plenty of food you need the colder settings. If you’re not storing as much and the temperature is very low, ice will form and it may prevent air circulation. Ice could also cause the fridge’s inner thermostat to malfunction. This may lead to electronics failure.
If ice accumulates: knock it off, lower the temperature and bear in mind that the change will take place in at least 8 hours.
Tip: Try to find a fridge thermometer, this way you can be absolutely sure your food is safely stored.
