LG Refrigerator: fan not functioning, not cooling
What is this symptom?
Is your LG refrigerator not cooling properly because the fan isn't functioning? This issue can lead to warm temperatures inside the fridge, often caused by a faulty evaporator fan motor or accidentally activated demo mode. Understanding the problem can help you restore cooling efficiently.
Important Tips for LG Models
- Certain LG models have demo/showroom or Sabbath modes that disable cooling and fan operation; consult manual for exit procedure
Possible Causes
Evaporator fan motor failure
How to Identify: No airflow from the freezer into fridge compartment, freezer may be cold but fridge warm, fan does not spin when door opened (if light switch bypassed
Part: Evaporator fan motor
Demo (showroom) mode / cooling mode disabled
How to Identify: Fridge powers on with lights/controls active but no cooling or fan operation; often seen after power surge or if demo mode was enabled
Part: Control settings (software)
DIY Solutions
Check and reset demo/Sabbath modes
- Consult your owner’s manual for button combination to exit demo or Sabbath mode
- Follow the sequence to ensure cooling mode is enabled
- Observe if fan starts and cooling resumes
Inspect airflow vents and defrost if blocked
- Remove food items from freezer
- Check for frost/ice blocking vents inside freezer
