Is my refrigerator temperature too high? I bought a packet of ready to eat chicken legs, ate a couple, and placed the rest in fridge. Today there are icicles on top of them. 
My fridge temperature is set between 3 and 4.  Is it too low?
There is no way to answer your question as it is stated.  Get a thermometer and measure the temperature inside your refrigerator over a few days.  It should hover around 37F (2.8 C).
