Refrigerator circuit board
To prevent static damage when handling the new control board, touch the metal refrigerator cabinet or wear a grounding strap.
The refrigerator will be without power for about 30 minutes, which shouldn't affect most refrigerated or frozen foods. However, you may want to move highly perishable food to a cooler.
Wear work gloves to protect your hands. Enlist a helper to pull the refrigerator forward.
This refrigerator shows how to replace an electronic control board in bottom-freezer and side-by-side refrigerators. The electronic control board is the "brains" of the refrigerator that controls major components such as the compressor and fans. If the electronic control board fails, the refrigerator can't cool correctly. It won't cool at all if the control board relay that turns on the compressor fails, which is the most common problem with a refrigerator control board (other failed parts can prevent the control board from running, such as the start device or overload fuse). Another symptom of a failed control board is that fans, lights or other components aren't working.
For a reliable diagnosis, have a service technician test the electronic control board. If you need to replace it, use the manufacturer-approved that fits your model.
Carefully pull the refrigerator forward and unplug the refrigerator. Move the refrigerator so you can easily reach the control board cover on the back of the refrigerator.
Locate the control board cover—idepending on the model, t could be on the back of the refrigerator, or inside the refrigerator on a side wall or the ceiling.
Using a Phillips screwdriver, remove the screws from the control board cover. Support the cover as you remove the last screw so it doesn’t fall. Remove the cover.
