← Full guide: Refrigerator Not Cooling — Protect Food, Then Diagnose Safely
Freezer is cold but refrigerator section is warm
If the freezer is cold, the sealed cooling system may still be working.
Start here
If the freezer is cold, the sealed cooling system may still be working. Focus first on airflow from freezer to fridge: vents, fan, damper/return path and frost/defrost blockage.
Check these first
- Confirm actual freezer and fridge temperatures.
- Check visible vents/returns for food or frost blockage.
- Listen for evaporator fan when the model should run it.
Fix it in this order
- Move food away from vents.
- If heavy frost blocks airflow, protect food and perform only the model-safe defrost process.
- If airflow/fan does not return or frost rapidly comes back, service the fan/defrost/damper system.
Evidence to keep
- Measured temperatures
- Frost/vent photos
- Fan sound
Do not make it harder
- Chipping ice with sharp tools
- Heat gun/hair dryer near plastic/refrigerant components
How you know it is fixed
- Fridge and freezer hold target temperatures and airflow remains clear without recurring frost.
If the obvious fix does not work
- If both compartments are warm, switch to whole-system cooling diagnosis.
- If a full defrost fixes it for days then the problem returns, that strongly suggests an underlying defrost/airflow fault.
If this still isn't resolved
- Appliance service
