A communication error between the main control board and one of the refrigerator's components — usually an evaporator fan or temperature sensor. The board can't read data from or send commands to the component.

Unplug for 5 minutes. Check all wire harness connections, particularly to the evaporator fan and temperature sensors. If connections are secure, a failed component or main control board is likely.
