Description
Norcold 639593 is the main rear control-board assembly number shown in service breakdowns for selected newer-model refrigerators. Unlike the interior optical display at the front of the cabinet, this assembly belongs to the rear electronics/control area. The exact board number must match the existing refrigerator configuration and wiring connections.
The parts diagrams describe 639593 as a main control-board kit or assembly, but a salvaged board may not include every item supplied in the original service kit. Before ordering, compare the board markings, mounting footprint, connector positions and complete refrigerator model against the unit being replaced.
