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. Discovering that your LG refrigerator and freezer not cooling can be a stressful experience, especially when you are faced with the potential of spoiled food and an unexpected repair bill.
LG Refrigerator Cool Air Flow Test: Inspecting Airflow for Optimal Cooling
Ensure the appliance is firmly plugged into a working electrical outlet and that the circuit breaker has not tripped, as a simple power interruption can stop the compressor from running. You should also inspect the door gaskets for cracks or gaps, as a poor seal allows warm, humid air to leak in, forcing the system to work harder until it can no longer maintain the target temperature.
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. 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.
