Understanding Communication Problems in Refrigerators❓

A communication problem in a refrigerator typically means that different internal components—such as the main control board, display panel, or inverter board—are not properly exchanging data. This can lead to malfunctioning features, incorrect temperature readings, or the unit not operating at all. The error often results from wiring issues, damaged connectors, or a fault in one of the control boards.
