Is there a schematic available,

My frig stopped being cold and there is huge frost buildup in the inside panels as well as the cooling element

Depending on your model I would call the company to see if there was a reecall on this as there is one model out there that does have a recall and does the same thing but in order to see if your falls in this you would need to call them give them your model and seral number wich is located inside on the wall of your refigrater and then they will ask you some questions to see if it qualitfiys for the recall and if it does the part would be coverd if it is over a year old if it is under a year old you still have a full warenty
