Low Medium High

Code Meaning Severity Common Symptom

C1 Board communication fault Medium The control panel shows C1 and may become partially unresponsive, with button presses having no effect. View C2 Inverter communication fault Medium The control panel shows C2, indicating the main PCB has lost communication with the inverter board that drives the variable-speed compressor. View DEF Defrost fault High The control panel shows DEF continuously or cycles the code with the current temperature reading. View DR Door seal fault Low The control panel shows DR when the door has been open beyond the programmed alert threshold or when the door seal is not creating an effective closure. View F2 Freezer thermistor fault High The control panel shows F2 continuously or alternates the code with the current temperature reading. View F4 Defrost sensor fault High The panel shows F4, often accompanied by progressive frost accumulation on the evaporator cover or rear freezer wall. View F5 Condenser thermistor fault Medium The control panel shows F5, indicating the controller cannot get a valid reading from the condenser or machine-compartment temperature sensor. View F6 Ice maker sensor fault Low The control panel shows F6, indicating a fault in the thermistor monitoring the ice maker zone or ice-making compartment temperature. View FAN Fan motor fault Medium The control panel shows FAN, indicating the controller has detected an abnormal fan motor current or speed signal. View FF Compressor overload High The control panel shows FF and the freezer may stop cooling entirely as the compressor shuts down on thermal protection. View HI High temperature alarm Medium The control panel shows HI and an audible beep sounds, indicating the freezer compartment temperature has risen above the controller's alarm threshold. View ICE Excess frost buildup Medium The control panel shows ICE when the controller detects conditions consistent with excessive frost accumulation in the freezer compartment. View
