Error Code Explained
What Does the Viking Temperature Sensor Fault Error Code Mean?
The temperature sensor (thermistor) in a Viking freezer monitors internal temperature and provides this data to the control board for compressor management. A failed sensor may report an incorrect temperature, causing the board to overcool (food freezes rock solid below normal freezer temperature) or undercool (temperature cannot reach 0°F).
