LG Refrigerator Control Board Replacement

简介

Use this guide to replace the control board on your LG refrigerator.

This guide will work for most LG refrigerators. This guide is written with an LG model LFX25973 refrigerator. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.

The control board is the brain of your LG refrigerator. It coordinates the function of the device, receiving inputs from various sensors, and controlling the function of other parts like fans, lights, alarms, and the refrigeration system components.

Failure of the control board can result in numerous problems ranging from complete failure of the appliance to odd alarms. Usually, the control board is one of the last components to check, because usually its failure is discovered through the elimination of other causes.
