Whether you’ve just bought a new refrigerator, moved to a new home, or experienced a temporary power outage, one question always comes up: how long does it take a fridge to get cold?
The short answer? Most refrigerators take 4 to 24 hours to reach their optimal cooling temperature, usually around 37°F (3°C) for the fridge and 0°F (-18°C) for the freezer. But several factors can affect that time range, and if you start loading it with food too early, you might compromise freshness and safety.
In this guide, we’ll break down how long different types of refrigerators take to get cold, what influences cooling time, and tips to help your fridge cool down faster.
Why Does It Take Time for a Fridge to Cool?
Refrigerators cool by circulating refrigerant through coils and transferring heat from inside the unit to the outside. When a fridge is first plugged in, it starts from room temperature—around 70°F (21°C) or higher—and needs to work consistently to bring the internal temperature down.
During this time, the compressor cycles on and off, fans distribute cold air, and sensors calibrate. Rushing the process by overloading the fridge or opening the door frequently can delay cooling even further.
Typical Cooling Times by Fridge Type
| Refrigerator Type | Estimated Time to Cool |
|---|---|
| Standard Top-Freezer Fridge | 4–12 hours |
| Bottom-Freezer Fridge | 6–12 hours |
| Side-by-Side Refrigerator | 8–14 hours |
| French Door Refrigerator | 12–24 hours |
| Mini Fridge | 4–8 hours |
| Commercial Refrigerator | 12–24+ hours |
Note: These are general guidelines. Your specific brand and model may vary. Always refer to the manufacturer’s manual.
Signs Your Fridge Is Cold Enough
You’ll know your fridge is ready to store food when:
- The internal temperature reaches 37°F (3°C) for the refrigerator and 0°F (-18°C) for the freezer.
- The compressor slows down or stops running frequently (indicating a stable temp).
- Condensation disappears from the interior.
- Bottled water or a thermometer inside the fridge reads consistently cold.
Pro Tip: Use an appliance thermometer to verify internal temps instead of guessing.
Factors That Affect Cooling Time
Several elements influence how long it takes for your refrigerator to cool:
1. Room Temperature
Hotter environments (like a garage or kitchen on a summer day) make your fridge work harder. A fridge in a cool, shaded area will reach temperature faster.
2. Size and Capacity
Larger fridges naturally take longer to cool. A full-size French door fridge may need 24 hours, while a small mini fridge can be ready in under 6.
3. Door Openings
Every time you open the fridge, warm air enters and delays the process. Try not to open the door during the first few hours after plugging it in.
4. Loading with Food Too Early
Putting warm or room-temperature food into a newly plugged-in fridge can spike internal temperatures and prolong cooling. Wait until it’s fully cold.
5. Air Circulation
Proper airflow is crucial. Don’t pack the fridge too tightly—leave room for cold air to circulate freely.
6. Initial Temperature
If your fridge was recently transported or stored in a hot warehouse, it may take longer to cool than one that’s been sitting in a cool space.
How to Make Your Fridge Cool Faster
Want to speed things up? Try these quick tips:
1. Keep the Door Closed
Avoid opening the fridge for at least the first 4–6 hours. Let the system stabilize.
2. Set It to the Coldest Setting Initially
Most fridges come with a temperature dial from 1–7 (or Low–High). Start at the coldest setting to kick-start cooling, then dial it back once optimal temps are reached.
3. Improve Airflow Around the Unit
Ensure there’s at least 2–4 inches of clearance around the sides and back of the fridge for proper ventilation. Blocked vents = slower cooling.
4. Place Ice Packs or Bottles of Cold Water
Adding a few frozen or chilled items (after an hour or two) can help absorb heat and speed up cooling.
5. Use a Fan Nearby (Optional)
In very hot environments, placing a fan near the back of the fridge (pointing at the coils) can help dissipate heat faster.
When Should You Put Food In?
Food should only go into the fridge once it has reached a stable 37–40°F (3–4°C). Placing perishable items inside too soon can lead to:
- Spoilage or foodborne illness
- Condensation and frost buildup
- Overworked compressor
Rule of thumb: Wait at least 4–6 hours (for small or medium fridges) or 12–24 hours for larger models before fully stocking it.
What If My Fridge Isn’t Getting Cold?
If your fridge isn’t cooling after 24 hours, try these troubleshooting steps:
- Check the power: Is it plugged in and getting electricity?
- Confirm thermostat settings: Is the temperature dial set correctly?
- Inspect the door seals: Make sure doors are closing fully and the gaskets are intact.
- Feel the coils: If they’re not warm, the compressor may not be working.
- Listen for the compressor: If it’s silent, there may be a mechanical or electrical issue.
If you’ve ruled out basic issues, it’s time to call a technician.
Final Thoughts
While it can be tempting to load your fridge right away, the best results come from letting it cool completely before use. Most refrigerators will reach safe food storage temperatures in 4 to 24 hours, depending on their size, location, and settings.
By keeping the door closed, checking the temperature with a thermometer, and avoiding premature food storage, you’ll ensure your fridge works efficiently and your food stays safe.
