This should be an easy one - I have just had to go buy a new-to-me refrigerator, and the loading & unloading process has the thing at about a 45 degree angle for a few minutes. Maybe 5.
In days of yore I was always told that a refrigerator should be allowed to stand upright overnight after having been moved, to allow the oil in the compressor to drain back down where it belongs.
However, I dimly recall being told that this was not necessary with newer refrigerators. This newish fridge is probably 5 years old or so.
So, does it need to be left upright for some lenght of time before being plugged in? If so, what is that period of time?
