Display shows E14 and the refrigerator may not defrost correctly or may show unusual frost patterns.

Safety first: Disconnect mains power before accessing internal freezer panels.

Step-by-step:

• Inspect frost pattern: Remove freezer drawers and look at the rear panel. Thick, uniform frost suggests defrost failure; patchy frost may indicate refrigerant issues.
• Access evaporator: Remove the rear panel to expose the evaporator, defrost heater, and sensors.
• Check sensor placement: Ensure the defrost/evaporator sensor is properly clipped to the tubing and not hanging loose.
• Inspect wiring: Look for partially burnt connectors or brittle wires that may fail intermittently.
• Defrost fully: Manually defrost the unit completely. This can temporarily restore operation and help confirm a defrost-related issue.

Action: Because E14 often indicates a more complex control/defrost interaction, professional diagnosis with proper test modes is recommended if the error recurs after a full defrost.
