Display shows H1 and the refrigerator compartment temperature is abnormally high.

Safety First: No internal electrical work is required for initial checks, but unplug the unit before removing panels.

Steps:

• Check doors: Ensure the refrigerator door closes fully and gaskets are clean and undamaged. Remove items that prevent proper closure.
• Inspect air vents: Inside the refrigerator, locate vents where cold air enters from the freezer. Move food items away to allow free airflow.
• Verify fan operation: Open the fridge door, press the door switch, and listen for the evaporator fan running (you may need to close the door switch manually). If silent, the fan or control may be faulty.
• Allow recovery time: After heavy loading or a long door-open event, allow 12–24 hours for temperatures to stabilize.
• Advanced checks: If H1 persists and the freezer is also warm, there may be a sealed system or compressor issue requiring a professional technician.
