How long does the refrigerator take to get cold?

Refrigerators have 2 key functions with 2 different compartments. The freezer compartment keeps food frozen and makes ice while cooling area preserves food. The time that a refrigerator gets cold depends on many different factors.

1. After a power outage

During the power outage, leaked heat gets accumulated inside the fridge and temperature goes up. The amount of heat will depend on how long the power cut lasts. Longer the duration of power cut, more time the refrigerator will need to come back normal condition.

How long a refrigerator gets cold depends on variety factors such as duration of power cut, refrigerant used in the fridge, temperature of outside environment, how much food is stored inside.

After a power outage of 3–4 hours, a refrigerator takes about 30 minutes to get cold and safe enough to store food inside. But note that this is just cold, not frozen. In hot countries, the cooling time will be a little longer, about 1 hour.

After a power outage of 3–4 hours, a refrigerator takes about 30 minutes to get cold
After a 3 hour-power outage, a refrigerator takes about 30 -60 minutes to get cold

For a frost-free refrigerator, it requires a longer time to cool down than a normal fridge. It may take about 4-6 hours to reach the right temperature because a frost-free fridge needs to remove the heat from the plastic, insulation, and metals that are inside.

When you suddenly find your fridge is not cold for a long time, you should contact a repairman to check and avoid the refrigerator running for a long time, leading to block failure.

2. For a new refrigerator

A new refrigerator needs about 24 hours to get to the right temperature for storing food. Setting the suitable temperature will be good for both fridge itself and food.
