If you gotta move it, your fridge, that is, it is best if it is moved upright. That is the best way to move it, but sometimes you just don’t have any easy way to do that.
So if it needs to be laid down, what will happen is the oil in the compressor will move up into the refrigeration system. If the oil stays in the system, it will block the refrigerant gas from moving within the system and once that happens it won’t move as the refrigerant tries to move upwards and the oil needs to find its way downwards to the compressor. So the oil must be given time to drain into the compressor. To give it time to drain, leave it AT LEAST 24 hours.
If moving it lying down, put it on its side, with the door slightly open. But remember, if you need to give your friends or family some cold beverages at the end of the day, keep those liquids in the esky (or the chillibun if you are from across the ditch)…just don’t start the fridge up yet.
