Viking Freezer Overcooling
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.
What Causes the Overcooling Fault Error?
The thermistor is reporting a higher temperature than actual, causing the board to keep the compressor running past the set point.
The compressor relay on the control board has stuck closed, keeping the compressor running continuously.
Basic Steps Before Calling a Technician
-
01Verify Temperature Settings
Confirm the freezer is set to 0°F and not a lower setting. Use an independent thermometer to verify actual internal temperature.
When to Call a Technician
Persistent overcooling despite correct settings requires professional diagnosis of the sensor or control board.
