DIAGNOSIS You likely moved it while it was running or laid it on its side, which can cause oil from the compressor to flood the cooling lines.
FIX Unplug the fridge and leave it standing upright, in its normal position, for at least 24 hours before plugging it back in. This allows any oil that migrated to drain back to the compressor.
IF THAT DIDN'T WORK The clicking is the compressor trying and failing to start. After the 24-hour rest, plug it directly into a wall outlet. If it still clicks and doesn't start, the compressor may have been damaged from the move.
HEADS UP Always transport this fridge upright if possible. If you must lay it down, let it stand upright for at least as many hours as it was on its side before plugging in. Transporting it horizontally while running is a sure way to kill the compressor.
