LG Refrigerator: fan freezing, scraping noise, ice maker not working
What is this symptom?
If your LG refrigerator is experiencing fan freezing, scraping noises, and the ice maker is not functioning properly, it could be due to ice buildup on the evaporator fan blades or restricted airflow. These issues can lead to annoying sounds when the fan runs and can halt ice production altogether. Understanding these symptoms is the first step toward restoring your refrigerator's performance.
Possible Causes
Ice buildup and frost on evaporator fan blades or housing
How to Identify: Scraping or rubbing noise in freezer; noise stops briefly when door opened; visible frost/ice accumulation on fan blades or housing.
Part: Evaporator fan and fan blades
Faulty ice maker components (motor/module/control board)
How to Identify: Ice maker does not cycle even in test mode; no movement in ice mold; other causes eliminated.
Part: Ice maker assembly including motor/module
Restricted airflow due to blocked vents or food packing
How to Identify: Poor cooling and frost buildup; airflow impeded; ice maker areas warmer than expected.
Part: Freezer airflow vents
