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.

  • 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
What's included: 1 main control board assembly Install notes:
  • 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
