How Long Does It Take for a Refrigerator to Get Cold?

When setting up a new refrigerator or restarting an inactive one, knowing how long it takes to reach the optimal cooling temperature is crucial. Discover the factors that affect a refrigerator's cooling time and learn how to ensure your appliance operates efficiently.

Typical Cooling Time for Refrigerators

Most refrigerators take between 12 to 24 hours to become fully functional and reach an optimal cooling temperature of around 37°F (3°C) for the fridge compartment. However, this time frame can vary based on several factors.

Factors Affecting Cooling Time

1. Type and Model of Refrigerator

Different refrigerator models have various cooling technologies that influence how quickly they reach the desired temperature:

• Top Freezer Models: These typically take longer to cool down, often closer to the 24-hour mark.
• Bottom Freezer Models: Similar to top freezers, they might require a full day.
• Side-by-Side Models: These tend to cool faster due to separate cooling systems for the fridge and freezer sections.
• French Door Models: Generally, they cool down more efficiently, with times closer to 12-16 hours.

2. Initial Temperature

If you're using a brand-new refrigerator, it will likely be at room temperature and will take longer to cool. On the other hand, a refrigerator that's restarted soon after being turned off might cool down more quickly.

3. External Temperature

The ambient temperature where the refrigerator is placed also affects its cooling speed. A hotter environment will slow down the cooling process, while a cooler environment facilitates quicker temperature attainment.

4. Contents and Load

Placing a large quantity of food into the refrigerator immediately can extend the cooling time as the appliance works harder to cool down all items. It's advisable to allow the refrigerator to cool first before fully loading it.

Best Practices for Efficient Cooling

Initial Setup

When you first set up the refrigerator, ensure it is placed in a location with adequate ventilation and away from heat sources like ovens or direct sunlight. Close the door promptly to maintain cooling efficiency.

Monitoring Temperature

Using an appliance thermometer can help track the temperature progress. Aim for 37°F (3°C) for the refrigerator compartment and 0°F (-18°C) for the freezer.

Proper Loading

Avoid overloading the refrigerator immediately. Allow the empty unit to reach its optimal cooling temperature before adding food gradually.

Regular Maintenance

Maintaining the coils, checking door seals, and ensuring an appropriate internal load will help optimize the refrigerator's efficiency over time.

Cooling Time Overview Table

By understanding these factors and following recommended practices, consumers can ensure their refrigerator operates efficiently and reaches the desired temperature within an expected time frame. If your appliance takes significantly longer to cool down, consulting the manufacturer's guidelines or seeking professional assistance may be necessary.
