Possible Causes
How to Fix / Troubleshooting
Safety: Do not attempt to open the sealed refrigeration system unless you are a certified refrigeration technician. High pressures and refrigerant handling require proper tools and training.
User-level checks:
- Ventilation: Ensure the condenser is clean and the unit has proper airflow. Poor ventilation can mimic low cooling performance.
- Door/bin sealing: Check that doors and bin lids close properly and gaskets are intact, preventing warm air infiltration.
- Ambient temperature: Confirm that the room temperature is within Vestfrost's specified operating range.
Technician-level actions (summary):
- Connect gauges to check system pressures and superheat/subcooling.
- Inspect for oil stains indicating refrigerant leaks at joints or evaporator.
- Repair leaks, replace filter drier, evacuate, and recharge with the correct type and amount of refrigerant as per the Vestfrost data plate.
Recommendation: If E11 appears and basic airflow and sealing checks are OK, contact an authorized Vestfrost service provider for sealed system diagnosis.
