We have to move a side-by-side refrigerator in a minivan, which means it can't be done upright. The general opinion seems to be that if you move it on its side, then let it stand a day after the move before you turn it on, and it'll be fine. On the net and web however, there is more detailed but conflicting information.
- Lay the fridge down with the suction line below, or pointing downward as it exits the compressor housing. The reasoning seems to be that the suction line is larger and there aren't any valves in it, so the oil can drain back faster compared to the compressor outlet side.
- Have the suction line above, because oil won't flow into the suction side, and the outlet side is closed by the compressor valves, so oil won't go there either.
Which side is better? It oil does migrate upward, is it necessary that every drop come back down, or is a little oil fine and will eventually come down as the compressor operates?
