3wif its just a refrigerator, it's not cold enough for cold testing. Comparing power to the light bulb, not likely. If I was using a refrigerator, it would be condensation/humidity testing. Placing the unit in and pulling out of the refrigerator will form condensation on the outside of the unit. And if its not sealed properly, on the inside of the unit.
