Low Medium High

Code Meaning Severity Common Symptom

CC Compressor control fault High The freezer compartment warms to ambient room temperature as the compressor is unable to run and the refrigerant cycle has stopped entirely. View DF Defrost cycle failure Medium Over days or weeks, the freezer struggles to maintain target temperatures as incremental ice buildup on the evaporator progressively restricts airflow. View FF Frozen evaporator / defrost fail High Food in the freezer begins to soften; the display shows temperatures above 0°F even though the compressor continues to run. View PF Power failure detected Low Depending on outage duration and how full the freezer was, some or all frozen contents may have warmed above safe freezing temperatures during the power interruption. View SY EF Evaporator fan system fault High The compressor is active and the evaporator coil is cold, but without fan circulation the cold air does not distribute through the compartment and temperatures rise. View TF High freezer temperature alarm High Ice cream softens, frozen items feel less solid, and the freezer interior temperature climbs above 0°F despite the compressor running. View
