ELI5 Why does a fridge need to be disconnected for hours after it has been transported? What happens if connected immediately?

The compressor oil settles in weird places when it's being transported. So you want to let it sit in the usual position for a while so the oil goes back to where it should be. It's thick and takes a while to settle. 

If you don't let it sit long enough, the motor could overheat and get ruined, and they aren't cheap to replace.
