I dealt with this when I was in Chicago in the winter--the refrigerator suddenly just stopped working.
I used a hair dryer to warm up the area behind the refrigerator, as well as a little electric cube heater, and sure enough, it started working again.
Then I think it happened again.
So I did as suggested here and put a trouble light in there to keep it from getting too cold. And if it was running on electric, I put cardboard over almost all of the vent.
That was several years ago, and since then, if the temperature is going to drop below about 10 degrees above zero, I put the trouble light in there, and I haven't had it stop working again, even down to 10 or more degrees below zero.
