Whirlpool Refrig clicking noise

[JohnD]

I have a Whirpool refrigerator about 4 years old. It is cooling properly but there has been a clicking noise coming from the temperture control panel inside of the frig. Does anyone have a clue? It seems to be cycling correctly.

I can't think of what sound the temperature control would be making. Is it clicking steadily, a lot, once in while, loud?

Without more info, I'd be inclined to suspect a vibration. Second gues would be that it is really something else, like the mullion heaters or defrost heater.
