Why is my whirlpool refrigerator not cooling the refrigerator, but freezer is -10 degrees

your sure the defrost cycle works? sounds to me its not. you need to remove the freezer back and check the defrost components. or put it in the defrost cycle and see if it is working. to get that much frost as you describe the dor would have to be left open. also check all door seals. let me know what you find and we can go from there

It is your defrost heater, you can get them from marcone.com with just your model number. Also at that web site you will get a exploded view of your unit. thiswill allow you to see the location of the heaters so you can just replace where the frost develops.
