Good evening,

Our Maytag refrigerator is not cooling at all. I cleaned out the condenser coils and replaced the defrost control board. I looked at it again this evening and the cooper tubing in the back was frozen over. I have attached a picture. It is the larger piece that froze. If you look closely, it still has a bit of ice on the bottom of it. I also checked the drain and water ran through it just fine. What am I missing.

Thanks in advance,

Jerry
