Samsung refrigerator error codes

Samsung washers and dishwashers show two-character codes such as 4C or 5C, where newer models use C at the end and older ones E, so 4C and 4E mean the same thing. Samsung refrigerators use codes like 22E or 39C for fan, sensor and ice maker faults, and ovens show C- codes such as C-d0 or C-21.
