Main Symptom:Fridge warm/Freezer fine

Error Code (if any): HI as fridge is over 50°

For Frigidaire FFSS2315TE0 with fridge warm / freezer fine and HI showing because the fresh-food section is above 50°F:

• Check evaporator frost pattern. Heavy frost/ice on the evaporator can block airflow into the refrigerator.
• Diagnose the defrost system: test the defrost heater/element ( Frigidaire 242044113 Refrigerator Defrost Heater | Genuine OEM Part ) for continuity and test the defrost thermostat ( Frigidaire 5303918214 Refrigerator Defrost Thermostat Kit | Genuine OEM Part ) . A failed heater or thermostat can cause the evaporator to ice over.
• Check the evaporator fan ( Frigidaire 242077705 Refrigerator Evaporator Fan Motor | Genuine OEM Part ) is running and moving cold air through the refrigerator damper.
• Check the air damper/vents ( Frigidaire 242303001 Refrigerator Air Damper Assembly | Genuine OEM Part ) for ice or blockage.
• Check for a clogged/frozen defrost drain. Ice buildup from a blocked drain can contribute to airflow/icing problems. Clear the drain and verify water flows freely to the drain pan.
• After repair/defrosting, allow the refrigerator to cool. The HI alarm should clear once the fresh-food temperature returns to the normal range.

Likely direction: If the freezer is maintaining temperature but the refrigerator is warm, focus first on airflow and evaporator icing/defrost failure rather than the sealed system.
