When to Call a Professional While cleaning condenser coils and checking door seals are tasks any homeowner can handle, some repairs require specialized knowledge and tools. Understanding the common reasons behind this cooling failure empowers you to move from panic to problem-solving, whether that means identifying a simple fix or knowing when to call a professional technician.
Diagnosing and Fixing LG Refrigerator Temperature Sensor Issues
Defrost System Malfunctions Modern LG refrigerators rely on an automated defrost system to melt frost that builds up on the evaporator coils; when this system fails, ice accumulation becomes rapid and severe. A clogged defrost drain line will cause water to pool at the bottom of the freezer, and that ice can eventually block the airflow entirely.
Preventative Maintenance for Lasting Cooling Performance. Similarly, a faulty compressor—the heart of the cooling system—will struggle to circulate refrigerant, causing the freezer to warm up while the refrigerator might remain cold or vice versa.
Diagnosing a Faulty LG Refrigerator Temperature Sensor
Another primary suspect is a dirty or clogged air filter in the return grille, which restricts the vital airflow needed to maintain the proper temperature throughout the cabinet. Furthermore, a defective defrost heater or timer will allow frost to build up unchecked, effectively insulating the coils and leading to the scenario where your LG refrigerator and freezer not cooling while the freezer feels excessively cold to the touch.
