Possible Causes
Poor heat transfer on evaporator due to scale, Defective hot‑gas valve or defrost solenoid (if equipped), Low refrigerant charge, Faulty evaporator temperature sensor
How to Fix / Troubleshooting
Safety first: Unplug the unit and keep it upright. Do not attempt to open the sealed refrigeration system unless you are a certified technician.
- Descale the evaporator: Remove the ice basket and inspect the evaporator fingers or plate. If you see white mineral deposits, run a descaling cycle using a manufacturer‑approved descaler or a diluted food‑safe descaling solution. Rinse thoroughly.
- Check airflow: Ensure the condenser fan is running and the rear grille is free of dust. Poor cooling can cause long freeze cycles and E5 errors.
- Sensor inspection: Verify that the evaporator NTC sensor is firmly attached to the evaporator and not dangling. Clean any corrosion and reseat the connector on the PCB.
- Professional service: If E5 persists and the evaporator does not frost evenly, the unit may have a refrigerant or hot‑gas valve issue. These require specialized tools and should be handled by a refrigeration technician.
