F38Warning
LG Refrigerator F38 Error Code
The refrigerator compartment temperature is too high (usually >50°F / 10°C). Often caused by poor air flow or a defrost issue.
Common causes
- Door left open or gasket leak
- Evaporator fan not running (see rF)
- Ice buildup blocking air flow from freezer
- Compressor or refrigerant problem
How to fix it
- Check refrigerator door closure and gasket condition.
- Ensure both refrigerator and freezer doors are closed; warm air from freezer can affect fridge.
- If evaporator coil in freezer is frosted, unplug and defrost.
- If fan is not running, check rF error code steps.
⚠ When to call a pro: Call a technician if code returns after defrost and doors are sealed, or if compressor is hot but not running.
