OEM part description
Genuine Sub-Zero electronic control board for select 400 Series and WS wine-storage refrigeration models. The board monitors temperature-sensor inputs and controls refrigeration-system operation, including compressor, evaporator fan, refrigerant-valve, lighting, and related operating functions according to the appliance configuration.
Part details
The electronic control board coordinates the appliance cooling system and responds to temperature information from the cabinet and evaporator sensors. Board failure can result in improper cooling, components that fail to run when commanded, intermittent operation, temperature-control problems, or other electrical symptoms.

Tech Tip: Do not condemn the control board solely because a compressor, fan, or other component is not operating. Verify incoming power, wiring connections, thermistor inputs, and the affected component before replacing the board. When handling the replacement board, hold it by the edges to reduce the risk of static-electric damage.
