Freezer space becomes fridge space...

The other situation is the oil in the compressor. It may thicken and cause
other problems when it does want to start.

Unplug it :-)

Third problem is freezing. If the ambient goes steadily below freezing, the
refrigerator will freeze also...

An EH38 "Easy Heat thermostatically controlled device" ($10.99 at Lowe's)
in series with a 100 W trouble light in a drawer can prevent freezing.
