Refrigerator problem - again!

[---MIKE---]

For the second time in four months I had to have service on my new refrigerator (under warranty). This is a low end Whirlpool with top freezer. There is only one temperature control. The freezer was at minus 30 degrees F while the refrigerator section was at 50 degrees. The problem was ice build up in the freezer drainage area that blocked the cold air from going to the lower section. The service man said there was nothing wrong with the unit. I noticed that the temp control was set a bit too low so after things were stabilized, the temp in the lower section was 30. I think this might have caused the ice build up so I reset it. What is the recommended temp for the refrigerator section? 35? 38? 40?

Im just guessing but maybe something is wrong with its defrost cycle or its drain tube system, -10 deep freeze and around 40 sounds normal. I bet the repairman did about zero and didnt care, does it frost up anywhere inside, I think there are electric heating elements around the deep freeze run on a timer to defrost it. In summer with high humidity and opening the door alot is when I would think ice would happen, maybe you got a lemon or some leftover chinese food behind the panel.

I think most are set at 40 and -10 for the freezer. Try setting the freezer warmer. And to check the temperatures, use a GOOD thermometer made for the job, not a regular thermometer. You want to measure product temperature, not air temperature. In the fridge you can put a thermometer in a glass of water for a good reading. The freezer needs the proper thermometer.
