Hello Dick Lee,
After carefully reviewing the symptoms you described, I believe the primary issue likely stems from a malfunctioning or faulty ice maker sensor. This sensor is responsible for detecting when the ice tray is full and signalling the ice maker to stop the ice-making process and initiate the emptying cycle. If the sensor fails to detect the ice tray's fullness accurately, it could lead to overfilling and subsequent water overflowing, resulting in the leakage you've experienced.
To address this problem effectively, we recommend scheduling a service appointment with an LG-authorized service repair technician if you are in our service area. Our technician will thoroughly inspect your fridge's ice maker system, including the sensor, to identify any faults or malfunctions. Depending on the findings, they will either recalibrate the sensor, repair any damaged components, or replace it if necessary. Additionally, they will conduct a comprehensive check of the water inlet valve, the ice maker mechanism, and the water supply line to ensure optimal performance and prevent future issues.
Please don't hesitate to contact our customer support team to schedule a service appointment at your earliest convenience.
