GE Refrigerator Main Control Board Replacement

Introduction

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

The main control board coordinates and controls all of the functions of the refrigerator.

If the main control board fails, virtually all of the functions of the refrigerator may be affected, depending on the severity of the failure. You may find that the refrigerator will not cool properly, the compressor may not run, and the water dispensing functions may be affected.

This guide was created using a GE model GSH25KGMB BB side-by-side refrigerator. Other GE refrigerators should be similar.

Using long nose pliers, squeeze the locking tabs on the mounting studs. While you do this, with your other hand pull the board gently outward so that the board won't slip back over a stud that has been released.
Lift the area of the board closest to the stud to free it from the mounting studs
Repeat this process of each mounting stud. until the board is free of each stud. Remove the board.
Try to work from one corner of the board down one side, then across. That will make it easier to maintain the gentle outward pressure and prevent the board from slipping back over the studs.
