LG Refrigerator Not Cooling — Problem Overview
The customer reported that the LG refrigerator was no longer cooling properly. Although a loss of cooling can have several causes, diagnostics showed that the problem in this case originated in the automatic defrost system.
The defrost heater is responsible for melting frost that naturally accumulates on the evaporator during normal refrigerator operation. If the heater fails, frost can continue building up around the evaporator and eventually restrict airflow through the appliance.
Restricted airflow can prevent cold air from circulating properly, resulting in rising temperatures even when other parts of the refrigeration system continue operating.
Diagnosis of the Issue
The technician inspected the refrigerator's cooling system and evaporator area to determine why the unit was not maintaining the correct temperature.
Diagnostic testing focused on the automatic defrost system and confirmed that the defrost heater was not operating correctly. Without sufficient heat during the defrost cycle, frost could not be cleared normally from the evaporator area.
The failure was isolated to the defrost heater, allowing the technician to proceed with replacement of the affected component.

Repair Result
After replacing the faulty defrost heater, the LG refrigerator returned to normal operation. The automatic defrost system could once again remove frost from the evaporator area, allowing proper airflow and cooling throughout the refrigerator.
Cost of Repair
The total cost of LG refrigerator defrost heater replacement can vary depending on the refrigerator model, replacement heater required, accessibility of the evaporator area, and labor involved.
