Refrigerator

Manufacturers ship refrigerators laying down in rail cars [on top of ones standing shipping air costs money] your refrigerator is fine
Been doing this (Refrigeration) for 38 years. Never once did I diagnose a seized compressor after owner advised they laid it down. Unless you transport it upside down very little oil will migrate out of the crankcase into the evaporator. Even if a significant amount did flow into the suction side, upon start up the oil would quickly be pulled right back into the crankcase with zero negative effect. Total yet everlasting myth. One other thing, since the suction tubes ( place where oil would run out) are always located on the sides of the compressor very little or no oil runs out. Unless of course they are laid on their front or sides, which no one does.
