Stupid refrigerator

I just paid the repairman $42.50 for him to come to my house, plug in the fridge, and say, "Now what was wrong with it? Because it's working now." What?! I was having a good day until these events transpired. I guess I should have plugged it back in a few days ago to see whether it would start cooling again. Why do I have to learn these things the hard way??
