Low Medium High

Code Meaning Severity Common Symptom

E1 Fridge sensor fault High Perishables such as dairy and meat deteriorate more quickly than normal because the compressor runs without accurate temperature feedback, causing the cabinet to run too warm or too cold. View E2 Freezer sensor fault High Ice cream softens, frozen meat develops ice crystals on the surface, and items that should be solid become partially thawed because the compressor cannot maintain the correct freeze temperature. View E3 Defrost sensor fault Medium Without working defrost cycles, ice accumulates on the evaporator behind the rear panel. After a week or more the frost can block airflow and reduce cooling efficiency noticeably. View E4 Ambient sensor fault Low With no ambient temperature data the control board defaults to a conservative cooling strategy, causing the compressor to cycle on more often — noticeable as increased running noise. View E5 Evaporator fan fault High You can hear the compressor operating and feel cold air at the back panel near the evaporator, but the main compartment does not cool because the fan is not circulating the air. View E6 Condenser fan fault High Without the condenser fan removing heat, the compressor and condenser coils at the back or bottom of the appliance become very hot — noticeably more than the slight warmth that is normal during operation. View E7 Ice maker fault Low The ice bin remains empty or ice production has stopped completely, even when the freezer temperature is at the correct level and the water supply is connected. View E8 Control board comm error High Without reliable communication between the main PCB and the display board, the user interface may freeze, show random symbols, or go completely dark while the appliance continues to run in a default state. View E9 Door open or switch fault Low If the door switch has failed in the open position, the interior light remains illuminated even when the door is shut, and the control board believes the door is still open. View EF High temperature alarm High Dairy products, meat, and other perishables feel warm to the touch or are above 5 °C (41 °F) when checked with a thermometer — indicating a genuine sustained temperature rise inside the cabinet.
