Description: Use this guide to replace the display board on...

Steps:

1. Unplug your refrigerator before you begin your repair.
2. If you are testing or repairing the following items, you may also need to shut off and disconnect the water supply:
3. Condenser fan motor
4. Compressor motor and thermal overload device
5. Water supply valve assembly

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

8. Pull the left door handle straight off to remove it.

9. 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:
10. Right side clips
11. Top clips
12. 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.)
13. 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.

14. Use a spudger to pry out the top edge of the dispenser assembly.
15. Once you've created a gap, use your fingertips to pull the edge downward.
16. Use additional spudgers to unfasten the clips securing the dispenser assembly to the refrigerator door.
17. 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.

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

20. Grasp the assembly firmly and pull it out of the refrigerator door.
21. 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.

22. Squeeze the multiple wire connectors and pull them straight off to disconnect them from the various PC boards.
23. Some of the connectors may be permanently attached to the PC board and can't be removed.

24. Squeeze and separate the various connectors in the wiring harness. The photo shows two examples.

25. Use a Phillips screwdriver to remove the screw securing the circuit board holder to the dispenser assembly. Many, but not all, units will have this PC board and holder.
26. Lift and remove the circuit board holder from the dispenser assembly.

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

29. Remove the tape securing wires to the rear of the dispenser assembly.

30. Remove the wires from the clip.

31. Pull the connector from the ice dispensing switch to disconnect it.

32. Use a Phillips driver to remove the screws securing the display board to the dispenser assembly.

33. Lift the display board off and remove it.
