Viking Dual-Zone Fault Error Code — Wine Cooler Fault Fix

Error Code Explained

What Does the Viking Dual-Zone Fault Error Code Mean?

Viking dual-zone wine coolers maintain separate temperature zones for different wine types. When one zone fails to maintain its set temperature independently — either running too warm or too cold — while the other zone is normal, the fault is typically in the zone temperature sensor, the zone air damper, or the zone control circuit.

Root Causes

Common Causes of the Viking Dual-Zone Fault Error Code

1

Failed Zone Temperature Sensor

The thermistor monitoring one zone temperature has failed, causing that zone to be mismanaged.
2

Stuck Zone Air Damper

The damper that controls cold air distribution between zones has stuck in an incorrect position, overcooling or undercooling one zone.
