My Kenmore 60791 series Refrigerator is making a squeeking noise?

My Kenmore 60791 series Refrigerator is making a squeeking noise. The noise is much louder when you open the refrigerator door, and appears to be coming from the area where the controls are, which has an opening. Can I fix this? Is this condition dangerous, i.e., can the thing catch on fire. This is my extra refrigerator that I keep in the garage. It is a 17 cu. ft. 60791 series with the freezer on top, and refrigerator underneath. The noise is a high-pitched squeeling sound, what you would expect from a bearing going bad.
