It's best avoided even for short distances, since any amount of time on its side lets compressor oil shift into the cooling lines. If it's unavoidable for a few minutes while navigating a tight doorway, keep the fridge upright as soon as possible afterward and give it extra rest time before plugging it in.
Extreme cold, well below freezing for extended periods, can make compressor oil thicken and gaskets stiffen. If your long-distance move crosses through very cold weather, give the fridge additional settling time indoors before powering it on.
Yes. Food left inside can spoil, shift and cause damage, or leak during hours of transit. Empty and defrost the unit at least a day before the movers arrive so it's fully dry and ready to load.
Being unplugged isn't harmful on its own as long as the unit is empty, clean, and dry. The risk comes from how it's transported (upright versus tilted) and how long it rests before restarting, not from the unplugged time itself.
A musty smell usually means moisture was trapped inside during transit, often from incomplete defrosting or drying beforehand. Wipe down the interior with a mild vinegar solution and leave the doors open for a few hours before restocking food.
