Amana refrig working intermittently! Help!

[COLOR=#000000][SIZE=3][FONT=Times New Roman]Hello.[/SIZE]

[SIZE=3]My 6 year old Amana refrig and freezer Model ARB220ZCB and S/N 10910704AJ warmed up 10 days ago and all freezer foods were spoiled. The refrig and freezer both warmed to room temp.[/SIZE]

[SIZE=3]It stayed that way for 3 days (it was over Labor Day weekend so no techs were available!) and then started acting "normal" for 3 days. Everything was working perfectly (frig was cold, freezer making ice, etc). [/SIZE]
[SIZE=3][/SIZE]
[SIZE=3]Then, this past Friday the refrig and freezer warmed up again. It’s "running" and everything "sounds" fine but something is definitely wrong. Do you have any suggestions?[/SIZE]
