| Error Code | Description | Solution |
|---|---|---|
| E1 | Refrigerator compartment sensor failure |
Check if the temperature sensor in the refrigerator compartment is damaged or disconnected. Sensor Test on digital multimeter (20k range): – 0 ≈ short – 1 ≈ open – More than 20K ≈ value shifted – Connectors rusted ≈ visual defect |
| E2 | Freezer compartment sensor failure |
This error typically indicates a failure in the freezer compartment temperature sensor. Sensor Test on digital multimeter (20k range): – 0 ≈ short – 1 ≈ open – More than 20K ≈ value shifted – Connectors rusted ≈ visual defect |
| E3 | Defrost sensor error |
Ensure that the defrost sensor is properly connected and functioning. Sensor Test on digital multimeter (20k range): – 0 ≈ short – 1 ≈ open – More than 20K ≈ value shifted – Connectors rusted ≈ visual defect |
| E4 | Defrost heater problem |
This error usually signals an issue with the defrost heater in the freezer. Heater test on digital multimeter (20k range): – 0 ≈ short – 1 ≈ open – More than 1k ≈ value shifted – Rusting ≈ visual defect on connectors |
| E5 | Ambient temperature sensor error |
This error occurs when the ambient sensor is defective. Test on digital multimeter (20k range): – 0 ≈ short – 1 ≈ open – More than 20K ≈ value shifted – Connectors rusted ≈ visual defect |
| E6 | Communication error between main control board and display panel | Check main PCB and display PCB wiring. Replace both PCBs if wiring is found good. |
| E8 | Evaporator fan motor issue | Verify that there is no ice buildup around the fan motor in the freezer. If the motor is damaged, it will need to be replaced. |
General Troubleshooting Tips:
- Power Reset: Try unplugging the refrigerator for a few minutes, then plug it back in.
- Check Ventilation: Ensure there’s at least 2 inches of clearance around the fridge for ventilation.
- Clean Condenser Coils: Dust and debris can affect cooling, so clean the coils regularly.
