The fridge should run at about 5 - 10 centigrade (41-50 F)
The cooling plate will be below freezing and will ice-up - keep foof away from the plate.
To stop ice building up the fridge automatically warms the cooling plate from time to time - melts the ice and the water drains away.
Perhaps the auto defrost function is defective. It will be cooler at the bottom.
Have someone call.
Good Luck..., April 2016
