When people ask how long does it take a fridge to get cold, they usually want to know one simple thing: when is it safe to put food inside? The general answer is that most full-sized residential refrigerators take 12 to 24 hours to reach a stable, food-safe temperature. In some cases, especially with larger models or after defrosting, it may take closer to 24 to 48 hours for the temperature to fully settle.
You may feel cold air inside the fridge after only a few hours, but that does not always mean the fridge is ready for meat, dairy, cooked leftovers, or other perishable foods. Cold air can move through the cabinet quickly, while shelves, drawers, walls, and the freezer section still need more time to reach a steady temperature.
The timing can also change depending on the situation. A brand-new fridge may need longer because it is cooling from room temperature for the first time. A fridge that was unplugged, cleaned, moved, or defrosted may also need time to stabilize again. The safest approach is to wait until the refrigerator reaches 40°F or below and the freezer reaches 0°F, which are the food safety temperatures recommended by the FDA.

Average Time a Fridge Takes to Get Cold
A standard full-size refrigerator usually takes about 12 to 24 hours to get cold enough for regular food storage. This is the most common timeline for home refrigerators after they are plugged in, reset, cleaned, or installed. Some fridges may begin blowing cold air within the first 2 to 4 hours, but the full interior temperature takes longer to become reliable.
The freezer section often needs a similar amount of time, and sometimes longer, to reach the correct freezing temperature. A freezer should reach 0°F before you add frozen food. If the freezer feels chilly but is not yet freezing solid, it is still not ready for items like meat, ice cream, seafood, or prepared frozen meals.
This is why “feeling cold” is not enough. Your hand can notice cool air quickly, but food safety depends on the actual temperature inside the appliance. A fridge can feel cold while still being above the safe range. For this reason, using a simple appliance thermometer is much better than guessing.
Cooling Time for a Brand-New Refrigerator
A brand-new refrigerator usually needs at least 24 hours before it reaches a stable temperature. Some models may cool faster, but it is still wise to give the fridge a full day before adding a large amount of perishable food. During this first day, the fridge is cooling every surface inside, including shelves, drawers, walls, door bins, and the freezer compartment.
Many newer refrigerators, including LG models, may start producing cold air within the first couple of hours, but LG guidance notes that newly installed refrigerators should be allowed time for the internal temperature to stabilize, and some cases may require 24 to 48 hours. LG also recommends waiting 24 hours after changing temperature settings before making more adjustments.
So, how long does it take for a new LG refrigerator to get cold? In normal home use, expect it to need around 24 hours for stable cooling. If the kitchen is hot, the fridge is full right away, or the doors are opened often, it can take longer. The best practice is to plug it in, set the correct temperature, keep the doors closed, and check the temperature before stocking it with sensitive food.
How Long a Fridge Takes to Get Cold After Being Unplugged
The time a fridge takes to get cold after being unplugged depends on how long it was without power. If it was unplugged only briefly, such as during cleaning behind the appliance or a short move across the kitchen, it may cool back down within a few hours. However, if it was unplugged for many hours, overnight, or during storage, you should treat it almost like a new setup and allow 12 to 24 hours.
If the fridge was moved, it may also need time to sit before being plugged in, especially if it was tilted during transport. This helps the appliance settle before running again. After it is plugged back in, keep the doors closed as much as possible and avoid adding warm food immediately.
You can restock the fridge when the refrigerator section is at or below 40°F and the freezer is at 0°F. If you are unsure how warm the fridge became while unplugged, be careful with old perishable food. Food safety should come before saving food that may no longer be safe.
Cooling Time After Cleaning or Defrosting
After cleaning, a fridge usually takes around 2 to 6 hours to feel cold again, but it may still need closer to 12 to 24 hours to become fully stable. Cleaning often involves keeping the doors open, removing food, wiping warm surfaces, and sometimes washing shelves or drawers. All of this allows warm air into the fridge.
If you are asking how long does a fridge take to get cold after cleaning, the safest answer is to give it several hours before returning food, and use a thermometer if the fridge was open for a long time. If the cleaning was quick and the fridge stayed partly cold, the recovery time may be shorter. If the fridge was unplugged and left open, it will need longer.
After defrosting, the cooling time can be longer. Manual defrosting warms the freezer walls and removes built-up ice, so the appliance has to cool the entire space again. Some refrigerators may take about 24 hours to return to normal after a full defrost, while certain cases can take up to 48 hours, especially if the unit had heavy frost or poor airflow before defrosting. LG support also notes that after defrosting, a refrigerator may take 24 to 48 hours to reach the set temperature again.
Small Fridges and Mini Fridge Cooling Times
Small fridges and mini fridges usually cool faster than full-size refrigerators. Many mini fridges can become cold within 2 to 4 hours, especially if they are empty and placed in a normal room-temperature space. However, they may still need longer to reach a steady temperature if the room is hot or the fridge is filled right away.
A small fridge has less interior space to cool, so it does not usually need as much time as a large French-door or side-by-side refrigerator. That said, mini fridges can also lose cold air quickly because they have less cold mass inside. Opening the door often can raise the temperature faster than it would in a larger fridge.
Mini fridges are useful for drinks, snacks, skincare products, office use, dorm rooms, and small spaces. For highly perishable foods like raw meat, milk, or seafood, you should be extra careful and confirm the temperature with a thermometer. Not every small fridge holds temperature as evenly as a full-size kitchen refrigerator.
How Long a Freezer Takes to Get Cold After Plugging In
A freezer usually takes around 12 to 24 hours to get cold enough after plugging it in. Some freezers may begin to feel cold in a few hours, but reaching 0°F takes longer. If the freezer is part of a refrigerator, its cooling time depends on the fridge model, room temperature, airflow, and how often the doors are opened.
Frozen food should only be added when the freezer is cold enough to keep it frozen safely. If you add frozen items too soon, they may soften, partially thaw, or develop ice crystals later. This can affect both quality and safety.
Freezer temperature matters more than the feeling of cold air. A freezer that feels cold may still be above freezing. Ice cream is often a helpful clue because it softens easily when the freezer is not cold enough, but a thermometer is still the best way to know the true temperature.
How Long a Fridge Takes to Cool Drinks
A fridge usually takes about 2 to 4 hours to cool drinks, depending on the drink size, container type, starting temperature, and fridge temperature. A small can of soda or water bottle will cool faster than a large juice bottle or a thick glass container. Drinks placed near good airflow may also chill faster.
The freezer can cool drinks faster, often within 30 to 60 minutes, but it must be used carefully. Cans and bottles can burst if forgotten in the freezer for too long. Carbonated drinks are especially risky because pressure builds as the liquid expands.
For faster chilling, place drinks in the coldest part of the fridge rather than the door. The door is usually warmer because it is exposed to room air whenever opened. If you need drinks cold quickly, using an ice bucket or ice water bath is often safer and faster than relying on the freezer.
Main Factors That Affect Fridge Cooling Speed
Several things can change how long it takes a fridge to get cold. Room temperature is one of the biggest factors. A refrigerator in a hot garage, warm kitchen, or poorly ventilated space has to work harder than one in a cool indoor area.
The size and style of the fridge also matter. Larger refrigerators, French-door models, and side-by-side units usually take longer to cool than compact models. They have more space, more shelves, and more surfaces that need to reach the right temperature.
Door openings can slow the process a lot. Every time the door opens, warm air enters and cold air escapes. During the first 24 hours, it is best to keep the doors closed as much as possible.
The amount of food inside also makes a difference. A completely empty fridge holds mostly air, and air warms quickly when the door opens. A moderately filled fridge can hold cold better, but adding too much food at once can block airflow and slow cooling. LG recommends keeping food from blocking vents so cold air can circulate properly.
Thermostat settings matter too. Setting the fridge too warm will delay safe cooling. Setting it extremely cold does not always make it cool much faster and may cause freezing in some areas later. Good airflow around the appliance is also important because the fridge needs space to release heat while it works.
Safe Refrigerator and Freezer Temperatures
The safe refrigerator temperature is 40°F or below, while many people prefer setting the fridge around 37°F for a little extra margin. The freezer should be at 0°F. These temperatures help slow bacterial growth and keep food safer for storage. The FDA recommends keeping refrigerators at 40°F or below and freezers at 0°F.
A thermometer is better than guessing because the fridge display does not always show the exact temperature in every area. Some displays show the set temperature, not the real temperature around your food. Door shelves, back corners, drawers, and the middle shelves can all feel slightly different.
Place an appliance thermometer in the refrigerator section and another in the freezer. Check them after the fridge has been running for several hours. For the most accurate reading, check again after 24 hours, especially after setting up a new fridge or changing the temperature.
Tips to Help Your Fridge Get Cold Faster
The best way to help a fridge get cold faster is to keep the doors closed. Opening the door again and again to check the air only slows the cooling process. Let the fridge run quietly and give it time to stabilize.
Avoid putting hot food inside. Hot pots, warm leftovers, or large containers can raise the interior temperature and make the fridge work harder. Let hot food cool safely for a short time before refrigerating it, but do not leave perishable food out too long.
Leave space around the air vents inside the fridge. If boxes, bags, or containers block the vents, cold air cannot move properly. This can make one area too warm and another area too cold.
Set the refrigerator to the correct temperature from the beginning. A good target is around 37°F for the fridge and 0°F for the freezer. If you change the setting, wait before changing it again because refrigerators need time to respond. LG recommends waiting 24 hours after temperature adjustments before making more changes.
Using a fridge thermometer is one of the simplest and most useful steps. It removes the guesswork and tells you when the fridge is actually ready for food.
Signs Your Fridge Is Taking Too Long to Cool
If your fridge is still warm after 24 hours, something may be wrong. It may be a simple issue, such as blocked vents, poor door sealing, wrong settings, or a warm room. But it can also point to a bigger cooling problem.
A freezer that is not freezing after a full day is another warning sign. If frozen items stay soft, ice does not form, or the freezer temperature does not move toward 0°F, the appliance may need attention.
A compressor running constantly can also be a sign that the fridge is struggling. Some running is normal, especially during the first day, but nonstop running with little cooling is not a good sign.
Unusual noises, weak airflow, water leaks, heavy frost, or warm spots inside the fridge can also mean the appliance is not cooling correctly. Before calling for repair, check that the fridge is plugged in properly, the doors are sealing, the vents are clear, and the temperature settings are correct.
When to Call a Technician
You should consider calling a technician if the fridge is still not cold after a full day of running. If it has been 24 hours and the refrigerator is above 40°F, or the freezer is far from 0°F, the appliance may need professional service.
You should also get help if the temperature keeps rising, even after the fridge seemed to cool at first. This can happen when there is a problem with the compressor, fan, thermostat, control board, dirty coils, or door seal.
Cooling problems after a power outage, cleaning, or defrosting may sometimes fix themselves once the fridge stabilizes. But if the appliance does not improve after enough time, it is better not to risk food safety.
A technician can check parts that are not easy or safe for most homeowners to inspect. If the fridge is new, contact the retailer or manufacturer support first, especially if it may still be under warranty.
Conclusion
So, how long does it take a fridge to get cold? For most full-size refrigerators, the answer is 12 to 24 hours. You may feel cold air sooner, but stable food-safe cooling takes more time. A new fridge, a fridge that was unplugged, or a fridge recovering after cleaning or defrosting may need a full day, and in some cases up to 48 hours.
Before adding perishable foods, check the real temperature. The refrigerator should be at 40°F or below, and the freezer should be at 0°F. A simple appliance thermometer is the easiest way to know when the fridge is ready.
The safest advice is simple: plug in the fridge, set the correct temperature, keep the doors closed, avoid adding hot food, and wait until the temperature is truly safe. This protects your food, helps the fridge work properly, and gives you peace of mind before restocking it.
