Customer Questions and Answers for Main Control Board (International) by Ge

This electronic main control board is the refrigerator's central controller. It manages cooling and defrost operations so temperatures stay consistent. Replacing a failed board restores normal performance and reliable operation.

• Regulates cooling by controlling the compressor and fan motors; failure may cause warm temperatures, no cooling, or intermittent cooling
• Manages the automatic defrost cycle; failure may lead to frost buildup or an ice-covered evaporator
• Distributes power and coordinates key components; failure can leave fans or the compressor not running or cause constant running
• Interfaces with temperature sensors and user controls; failure can trigger error codes, clicking/beeping, or unresponsive controls

• Disconnect power to the refrigerator before servicing
• Use anti-static precautions; handle the board by the edges and avoid touching components
• Photograph and label wire connections; transfer plugs and secure all connectors fully
• Mount in the original location/enclosure and ensure wires are not pinched by covers
