Amana Side by side Fridge ARSE66ZBW

Question

Opened up the freezer tonight. Sounded after I opened the door spitting noises were going on. The back of the pull out basket was warm and I could see red coils behind it. We were concerned about leaving it plugged in because of a overheated type smell so we transferred all frozen stuff to another freezer. Any ideas on what to do or what is wrong. Just spent $350 on icemaker and water and ice dispeser in the door. Ahhhhh!
