Introduzione

Use this guide to replace the display board on your LG model LFX25973 refrigerator.

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.

Strumenti

Passo 1

Unplug your refrigerator before you begin your repair.
If you are testing or repairing the following items, you may also need to shut off and disconnect the water supply:
Condenser Fan Motor
Compressor Motor and Thermal Overload Device
Water Supply Valve Assembly

Passo 2

To remove the left door handle, first open the right door.
Use a 2 1/2 mm hex wrench to loosen the set screws in the top and bottom of the left door handle.

Passo 3

Pull the left door handle straight off to remove it.

Passo 4

The dispenser assembly is secured by very strong clips, making it very difficult to remove. Take note of the clip locations 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.

Passo 5

Use a spudger to pry out the top edge of the dispenser assembly.
Once you've created a gap, use your fingertips to pull the edge downward.
Use additional spudgers to unfasten the clips securing the dispenser assembly to the refrigerator door.
Optionally, you may use a flat-blade screwdriver to assist in this process. Be careful not to damage the door; you may scratch the door surface or dent the rim of the dispenser opening.

LG offers a method to release the dispenser as follows: 1. Pull out the drain pan. 2. Hold the inner side of the dispenser cover with both hands at the handle/paddle to pull it forward. 3. If the nozzle interferes with the button, push it out of the way. Note: We were unable to do this. The service manual was unclear.

Passo 6

Grasp the top edge of the dispenser assembly in the middle and pull outwards.
Continue prying and pulling around the perimeter of the assembly to release it.

Passo 7

Grasp the assembly firmly and pull it out of the refrigerator door.
Don't try to pull the assembly completely off the refrigerator door. The assembly is still connected with numerous wires. These are mainly connected to the left side of the dispenser.

Passo 8

Squeeze the two multiple wire connectors and pull them straight off to disconnect them from the display board.
Do not attempt to remove the four-wire connector from the board as it is not removable.

Passo 9

Squeeze and separate the two-wire harness connector and the four-wire harness connector.

Passo 10

Use a Phillips screwdriver to remove the 11 mm‑long screw securing the white circuit board holder to the dispenser assembly.
Lift and remove the circuit board holder from the dispenser assembly.

Passo 11

You can now remove the dispenser from the refrigerator.
The white circuit board holder can be suspended from the harness wires, as its weight is minimal.
