LG Refrigerator Display Board Replacement

简介

Use this guide to replace the display 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 display board shows the status of your refrigerator.

If it fails, a number of features on the dispenser may not work, including the ice type selection and temperature settings.

Gaining access to the display board takes some effort. You will have to remove the dispenser assembly, which can be somewhat difficult.

    • The dispenser assembly is secured by very strong clips, making it very difficult to remove. Take note of the clip location examples shown in the photos:

    • Right side clips

    • Top clips

    • Left side clips (Note, the dispenser is being held upside down for the photo, so the upper left side clips are at the bottom of the photo.)

    • During disassembly, you may break some of these clips. If you do, don't worry; the assembly does not need all the clips to be properly secured.
