Fridge temps critical, but fine now, should I be worried?

Fridge temps critical, but fine now, should I be worried? A little background, this is a GE fridge, about 9-10 years old. Last year the overload relay on the compressor failed and I had to replace it. I purchased some thermometers to monitor temps since then. The fridge temp seems to range 35-40 and freezer -5 to 5.
