How Long to Wait Before Plugging In a New Refrigerator

Wait at least 4 hours after delivery before plugging in your refrigerator

If your refrigerator was transported on its side or at an angle during delivery, you need to let it sit upright and still before turning it on. Most manufacturers recommend waiting 4 to 8 hours—some say 24 hours for safety. This pause lets the refrigerant and oils settle back into their proper places inside the sealed system. If you plug it in too soon, you risk damaging the compressor, which is the heart of the cooling system and expensive to replace.

The reason is practical: when a refrigerator tilts during transport, the refrigerant oil can flow into parts of the system where it doesn't belong. Turning on the compressor before that oil drains back creates friction and heat that can permanently harm it. A few hours of waiting costs nothing and protects your investment.

Key Takeaways

• Most refrigerators should sit upright for 4 to 8 hours after delivery before you plug them in, though some manufacturers specify 24 hours.
• The wait allows refrigerant oil to settle back into the compressor where it belongs, preventing damage when the cooling system starts.
• If your refrigerator was delivered upright and never tilted, you can plug it in sooner, but check your manual for the exact requirement.
• Plugging in too soon can damage the compressor and void your warranty, so the waiting period is worth the delay.

Check your manual for the exact waiting time

The waiting period varies by brand and model. Your refrigerator's manual—either in the box or on the manufacturer's website—states the specific time you should wait. Some brands like Whirlpool and LG recommend 4 hours; others like Samsung may ask for 8 to 24 hours. Checking the manual takes two minutes and gives you the manufacturer's exact requirement for your model.

If you no longer have the physical manual, visit the manufacturer's website and search for your model number (usually on a sticker inside the fridge or on the back). Download the PDF or call their customer service line—they can tell you the waiting time over the phone. This is not a guess; it is the rule that protects your warranty.

How to know if your refrigerator was transported on its side

Delivery trucks often lay refrigerators flat to fit more units, or they tilt them to maneuver through doorways. If you were not present during delivery, ask the delivery driver whether the refrigerator was upright the entire time. Most drivers will tell you honestly. If it was tilted or laid down at any point, follow the full waiting period your manual specifies.

If you are unsure and cannot reach the driver, err on the side of caution and wait the full time anyway. A few extra hours of waiting is a small price compared to a broken compressor. Some people wait 24 hours simply because they are uncertain—that is a safe choice.

What to do while you wait

Use the waiting time to prepare your refrigerator for use. Wipe down the interior with a damp cloth to remove dust from the factory and shipping. Check that the shelves and drawers are in place and that nothing is blocking the vents at the back. Make sure the space around your refrigerator has at least 1 inch of clearance on the sides and back so air can circulate and the compressor can cool properly.

Clean the coils on the back or underneath the unit if they are visible and dusty. Dust buildup makes the compressor work harder and shortens the life of the refrigerator. You can use a vacuum with a brush attachment or a coil-cleaning brush, which costs a few dollars at any hardware store. These tasks take 15 to 30 minutes and prepare the refrigerator to run efficiently from day one.

Plugging in and the first run

After the waiting period has passed, plug the refrigerator into a grounded outlet (a three-prong outlet, not an extension cord). Turn it on and set the temperature dial or digital controls to the middle setting. You may hear clicking, humming, or a brief whooshing sound as the compressor starts—this is normal. The refrigerator will take 2 to 4 hours to reach its target temperature, so do not load it with food immediately.

Let it run empty for those first few hours. This allows the system to stabilize and the temperature to drop evenly. After 4 hours, check that the interior feels cold to the touch. Then you can begin loading food, starting with items that need the coldest temperatures (like meat and dairy) on the lower shelves where it is coldest.

What happens if you plug in too soon

Plugging in a refrigerator before the waiting period can damage the compressor. The compressor is a sealed motor that pumps refrigerant through the system to create cold. If oil is in the wrong place when it starts, friction builds up and the motor can burn out. A burned-out compressor means the refrigerator will not cool at all, and replacing it costs several hundred dollars—sometimes more than the refrigerator itself.

Most manufacturers will not cover compressor damage under warranty if you plugged in the unit before the recommended waiting time. This is why the waiting period is printed in the manual: it protects both the machine and your coverage. Even if you are eager to use your new refrigerator, the wait is worth it.

Frequently Asked Questions

Can I plug in my refrigerator after 2 hours instead of 4?

No. The minimum recommended time is 4 hours for most models, and some require 8 to 24 hours. Waiting less than the manufacturer specifies risks compressor damage and may void your warranty. If your manual says 4 hours, wait the full 4 hours.

What if my refrigerator was delivered upright and never tilted?

Even if it was upright during delivery, check your manual. Some manufacturers still recommend a waiting period as a precaution. If your manual explicitly states you can plug it in immediately when delivered upright, you can do so—but confirm this in writing from the manual or manufacturer first.

Does the waiting time matter if I have an older used refrigerator?

Yes. If you transported a used refrigerator yourself and it was tilted or laid on its side, let it sit upright for 4 to 8 hours before plugging it in. The same risk applies: oil needs time to settle. If you are unsure of the model, waiting 8 hours is a safe default.

Can I open the doors while the refrigerator is waiting to be plugged in?

Yes. Opening the doors does not affect the waiting period. You can clean the interior, arrange shelves, or inspect it while it sits. Just do not plug it in until the time has passed.

What temperature should I set it to when I first turn it on?

Set the dial or controls to the middle setting (usually marked as "3" or "Medium" on analog dials, or 37–40°F on digital displays). This is the standard refrigerator temperature. Avoid setting it to the coldest setting right away, as this puts extra strain on the compressor during its first run.
