Display shows H1 or HI in the refrigerator section, indicating high temperature.

Safety First: Avoid leaving doors open while troubleshooting to prevent further temperature rise.

Steps:

• Check door and loading: Ensure the door closes fully and that food items are not blocking air vents at the back or sides.
• Listen for fan: With the door switch held closed, listen for the evaporator fan running. If silent, see evaporator fan fault procedures.
• Verify freezer temperature: If the freezer is cold but fridge is warm, suspect airflow issues or a bad refrigerator thermistor.
• Reset alarm: Clear the H1 code per the user manual and monitor temperatures for 24 hours. If it returns, test the refrigerator thermistor and fan as described in related entries.
