Display shows Hi and an alarm may sound; freezer interior is warm and food may be soft or thawing.

Safety First: Disconnect power before removing panels or working near moving parts.

Hi indicates the freezer temperature has risen above the safe range.

• Step 1 – Check door and gasket: Ensure the door is fully closing and the gasket is intact and sealing all around. Remove any items blocking closure.
• Step 2 – Verify fan operation: With the door switch held closed, listen for the evaporator fan running when the compressor is on. If silent, test and replace the evaporator fan motor as needed.
• Step 3 – Inspect for frost buildup: Remove the rear interior panel. Heavy frost on the evaporator indicates a defrost failure; test the defrost heater and thermostat.
• Step 4 – Check condenser and airflow: Clean condenser coils and ensure the condenser fan (if equipped) runs when the compressor runs.
• Step 5 – Sensor and control: If actual temperature is normal but Hi displays, test the freezer thermistor and replace if faulty. If sensor is good, replace the control board.
• Step 6 – Sealed system: If the evaporator shows only partial frost or no frost while the compressor runs, a sealed system problem is likely. This requires a licensed refrigeration technician.
