Alarm for high refrigerator temperature with F11, compressor runs but temperature does not drop adequately

Safety first: Unplug the refrigerator before cleaning or accessing rear components. Do not attempt to open the sealed system.

Steps:

• 1. Check loading and settings: Ensure the temperature is set correctly and the refrigerator is not overloaded, blocking air vents.
• 2. Inspect door seals: Poor sealing can cause high temperatures. Check for gaps or torn gaskets.
• 3. Clean condenser: Pull the unit away from the wall. Vacuum dust from the condenser coils and the condenser fan (if fitted) at the rear or underneath.
• 4. Verify ambient conditions: Extremely high room temperatures can reduce cooling efficiency. Ensure adequate ventilation around the appliance.
• 5. Observe frost pattern (advanced): With the rear interior panel removed, a normal evaporator should have an even frost pattern. Frost only on a small section suggests a sealed system issue.
• 6. If cleaning and ventilation do not resolve F11: The problem may be a refrigerant leak, restriction, or failing compressor. These require specialized tools and must be handled by an authorized V-ZUG technician.

Warning: Do not attempt to recharge refrigerant or cut into copper lines yourself.
