On the occurrence of a malfunction of the refrigerator signal flashes the indicators on the front panel or codes of errors appear on the display of the freezer temperature indicators.
The error code flashes on the display alternates with the freezer temperature display. If errors occur, it is necessary to turn off the refrigerator, disconnecting it from the mains. After a while, turn it on again.
The temperature display in the freezer may display error codes:
E2 - the EP4 does not receive a signal from the temperature sensor in the freezer
E4 - the information on the temperature mode of the refrigerating chamber does not reach the control unit EP4 of the control panel
E6 - the unit EP4 does not receive signals from the temperature sensors of the refrigerator, which are responsible for the freezing and refrigerating compartments. The data transmission signal is broken. It is necessary to contact a specialist in the repair of refrigerators. Self-repair of such a breakdown can further exacerbate the malfunction.
Also, the faults can be detected by the light indicators, the flickering of which indicates various malfunctions in operation, which may require the replacement of the thermostat or the repair of the evaporator.
