Possible Causes
Defective defrost heater, Failed defrost sensor or thermostat, Door gasket leaking warm air, Frequent door openings or warm food loading
How to Fix / Troubleshooting
Safety first: Unplug the freezer before defrosting or accessing electrical components.
- 1. Perform full manual defrost: Remove all food, unplug the unit, and leave the door open until all ice has melted. Use towels to collect water.
- 2. Check door gasket: Inspect the gasket for tears or gaps. Close the door on a sheet of paper; if it pulls out easily, the seal is weak. Replace the gasket if necessary.
- 3. Test defrost heater and sensor: Access the evaporator and test the defrost heater and NTC/thermostat as described for E4. Replace any faulty components with Severin-compatible parts.
- 4. Avoid overloading and frequent openings: Allow hot food to cool before placing in the freezer and minimize door openings to reduce moisture ingress.
- 5. Monitor: After repair, monitor frost buildup over several weeks. Persistent heavy frost suggests a remaining defrost system fault.
