Error Code Explained
What Does the Viking Overcooling Fault Error Code Mean?
A Viking freezer that runs significantly below the set temperature — dropping to -20°F or lower when set to 0°F — has a fault in the temperature sensing or compressor control system. Food items may become extremely hard or crystallize more than expected. The control board is not receiving an accurate temperature reading to cycle the compressor off at the correct point.

-
1Failed Temperature SensorThe thermistor is reporting a higher temperature than actual, causing the board to keep the compressor running past the set point.
-
