How Long Does a New Refrigerator Take to Get Cold?
Short answer: 4 to 24 hours. Fridge to 37–40°F in 4–6 hours, freezer to 0°F in 4–12 hours, full stability at 24. Here's what's normal, what's not, and how it breaks down by brand.
The straight answer
Most new refrigerators reach safe food-storage temperature within 4 to 6 hours and are fully stable within 24 hours. Wait for the freezer compartment to hit 0°F before loading frozen food — that's the honest indicator, not the fridge temperature display.
By brand
| Brand | Fridge to 37–40°F | Freezer to 0°F |
|---|---|---|
| Samsung (Twin Cooling) | 4–6 hours | 8–12 hours |
| LG (linear compressor) | 3–5 hours | 6–10 hours |
| Whirlpool / KitchenAid | 4–8 hours | 8–14 hours |
| Sub-Zero built-in | 2–4 hours | 4–8 hours |
| Frigidaire / GE side-by-side | 6–10 hours | 10–16 hours |
| Chest freezer (any brand) | — | 4–8 hours empty |
Before you plug it in
If the refrigerator was transported on its side or tilted more than 45°, leave it upright and unplugged for 2–4 hours so the compressor oil can drain back into the compressor. Plugging in too soon is the single most common cause of a compressor failure in the first month of ownership.
Common causes of a new fridge not getting cold
- Demo / showroom mode — display shows a snowflake, "OF", or "d" code. Look up the model's demo-mode exit code (usually holding two buttons for 3 seconds).
- Door not fully sealing — a business card should not slide out of a closed gasket.
- Blocked airflow — leave at least 1 inch of clearance behind and above the unit for the condenser to breathe.
- Overloaded before it's cold — packing warm groceries into a not-yet-cold fridge doubles the time to setpoint and stresses the compressor.
- Shipping damage to the sealed system — rare but real. If it's not cold after 24 hours with the door closed and a normal setpoint, contact the retailer for warranty service.
When to call a repair tech
If the refrigerator is more than a few months old and now takes longer than 24 hours to get cold — or never reaches setpoint — that's not a break-in issue, that's a repair. Common failures: condenser-fan motor, evaporator-fan motor, defrost heater, or a sealed-system refrigerant leak.

FAQ
How long does a new refrigerator take to get cold?
A new refrigerator typically takes 4 to 24 hours to reach a safe food storage temperature of 37–40°F in the fridge compartment and 0°F in the freezer. Most modern side-by-side and French-door units are cold enough to store food after 4–6 hours and fully stable within 24 hours. Wait for the freezer to hit 0°F before loading food — that's the true indicator.
How long does it take for a new refrigerator freezer to get cold?
The freezer compartment on a new refrigerator typically reaches 0°F within 4 to 12 hours. Don't load frozen food until the freezer hits 0°F on the display or on an appliance thermometer — loading warm food into a not-yet-cold freezer overworks the compressor and can shorten its life.
How long does a Samsung refrigerator take to cool down?
Samsung recommends waiting at least 2 hours after installation before plugging in (to let the refrigerant settle), then 24 hours for full cooling. Most Samsung French-door models reach fridge temp (37°F) in 4–6 hours and freezer temp (0°F) in 8–12 hours. Twin Cooling Plus models cool faster because the two compartments have separate evaporators.
How long does an LG refrigerator take to get cold?
LG linear-compressor refrigerators typically reach fridge temperature in 3–5 hours and freezer temperature in 6–10 hours. LG's inverter linear compressor ramps down as it approaches setpoint, so the last few degrees take longer than the first — that is normal, not a failure.
How long does a chest freezer take to get cold?
Chest freezers typically reach 0°F in 4–8 hours empty. Because they're sealed on top and have no auto-defrost cycle, they hold temperature very well once cold — but loading warm food during the initial pull-down will extend the time to 24+ hours.
Why is my new refrigerator not getting cold after 24 hours?
After 24 hours a new refrigerator should be at set temperature. If it's not, the most common causes are: (1) the unit was tipped during delivery and refrigerant hasn't settled — wait another 4 hours upright; (2) door not sealing (check the gasket); (3) demo mode / showroom mode is on (check the display for a snowflake or 'OF' code); (4) sealed-system leak from shipping damage — call the retailer for warranty service.
Do I need to wait before plugging in a new refrigerator?
Yes. If the refrigerator was transported on its side or at an angle, wait 2–4 hours before plugging in so oil can drain back into the compressor. If it stayed upright the whole trip, you can plug it in immediately but leave it empty for the first 4 hours to reach temperature.
What temperature should a refrigerator be set to?
USDA recommends 37–40°F for the fridge compartment and 0°F for the freezer. Most factory defaults hit those targets — leave the temperature settings alone for the first 24 hours and let the appliance stabilize before adjusting.
