How to Fix / Troubleshooting

Safety first: Unplug the freezer before accessing the evaporator and electrical components.

Steps:

Manual defrost: Defrost the freezer completely to restore airflow temporarily.
Access evaporator: Remove the internal rear panel to expose the evaporator coil and defrost components.
Check heater and thermostat: Visually inspect for burnt heater elements or damaged thermostats. Use a multimeter (if competent) to test continuity of the heater and defrost thermostat.
Replace faulty parts: Install genuine Beko defrost heater and/or thermostat if open-circuit.
If all defrost components test good, the defrost sensor or main control board may be at fault and should be diagnosed by a technician.

Heavy frost or ice build-up on evaporator and rear panel, fan noise may increase
