• Manages incoming power and distributes voltage to displays, sensors, and motors
• Controls compressor, fan, and defrost cycles via signals to other modules
• Can cause blank displays, no power to lights, or intermittent operation when faulty
• May stop appliance functions like cooling if the board no longer responds

• Disconnect power to the appliance before starting any repair to avoid shock or damage
• Handle the board carefully and avoid touching components; use anti-static precautions if available
• Verify the board part number matches the one on the appliance before installation
