Hi Wendy, and thank you for using Just Answer
This fridge should be frost free. There is a heater by those cooling coils to prevent condensation from icing and plugging up the air flow from your fan. Thant heater is bad and needs to be replaced. Since this fridge is a year old, there is still a chance that it is covered under warranty. They offer a 12 month parts and labor however good companies will still cover their items when they go beyond by 1 or two months. I wish you the best.
