Hello
Magic Chef refrigerator/freezer CTN1911GEW. The refrigerator on the bottom is at the correct temperature. But the freezer at the top is defrosting the food. The fan in the freezer is working. How can I get my freezer to work right again?

Please advise.
Many thanks
Michel

Is it defrosing? Is there ice or frost build up on the evaporator? Have you cleaned the condensing fan and coils at rhe backside rear of unit?
