What Does Error Code SY CE Mean on a Electrolux Refrigerator?
Communication error between control boards.
SY CE fires when the main power board and the display/user-interface board stop exchanging data over their communication line. The main board expects periodic handshake signals; when those drop out or become corrupted, it flags the fault. The sealed system keeps running on the last stored settings, so cooling continues while the display may blank or freeze. This distinguishes SY CE from sensor or thermistor faults, which report specific temperature-probe failures rather than a board-to-board link loss.
