Many people have heard that after buying a new refrigerator, or moving an old one, you need to let it sit for a while before plugging it in.
Depending on the brand and model, some manufacturers recommend waiting 2 hours, some say 30 minutes, and others just 5 minutes. So, why is there such a difference, and what’s the real reason behind it? Let’s break it down.
Why You Should Let a New or Moved Refrigerator Sit
There are two main reasons you should let your refrigerator sit after moving it:
1. Allow the Oil to Flow Back Into the Compressor
Refrigerators rely on compressors to cool properly, and the compressor contains lubricating oil. When a refrigerator is moved—especially if it’s laid on its side or tilted—the oil can flow into the refrigerant lines.
If you power it on immediately, the compressor might run without sufficient lubrication, leading to potential damage or accelerated wear and tear. In severe cases, the compressor could fail completely and become unusable.
2. Prevent Abnormal Accumulation of Refrigerant Liquid
Refrigerant is supposed to enter the compressor as a gas. However, after moving the fridge, some refrigerant liquid may end up where it shouldn’t be, such as in the suction line.
If you turn on the refrigerator right away, it can cause a phenomenon known as “liquid slugging,” where the incompressible liquid damages internal compressor parts due to sudden abnormal pressure.
How Long Should You Let a Refrigerator Sit After Moving?
So, how long should you actually wait?
First, always check the manufacturer’s instructions and follow their recommendations. This information is usually listed early in the user manual. If you can’t find the manual, here’s a general guide:
If the Refrigerator Was Moved Upright
If the fridge was kept upright during transportation, the compressor oil and refrigerant likely haven’t shifted much.
In this case, letting it sit for 1 to 2 hours is typically enough to stabilize the cooling system.
If the Refrigerator Was Tilted or Laid Down
If the fridge was tilted significantly or laid on its side, it’s safer to wait at least 4 to 8 hours before plugging it in.
Some manufacturers even recommend waiting 12 hours or more to be extra cautious.
Final Reminders
Refrigerators vary widely across brands and models.
Some models might require 12 to 24 hours of resting time, while others are ready to be plugged in immediately.
If you’re unsure about your specific refrigerator, or if you’re not in a rush to use it, it’s always safer to let it sit for a full day before turning it on.
