I know the temperature in ours fluctuates depending on what we put in it. If we just put refrigerated items in it like cold cuts, milk, soda etc., it usually remains consistent. However, if we load it with frozen food the temp will drop 8 or more degrees. That's on the display, I haven't checked the actual temperature with a thermometer, but I think I'll start looking into it. If I discover anything noteworthy, I'll let you know.
