When should you replace the main control board?

The main control board is the brains of the refrigerator and controls all of the major functions and parts like the compressor, fan, defrost cycle, icemaker, and temperature settings.

Here are some signs that typically indicate there is an issue with the control board and it likely needs to be replaced:

• The refrigerator does not turn on at all
• Fridge or freezer interior is too warm or too cold
• The refrigerator runs constantly or for very long cycles
• Problems with the automatic defrost function lead to frost build-up
• The icemaker stops making ice unexpectedly

If your refrigerator is exhibiting any of those common symptoms, replacing the main control board will likely resolve the problem. Check the user manual for your specific model number to confirm the control board is failing before ordering a replacement part.

Safety first

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:

• Unplug the refrigerator or turn off the circuit breaker to avoid the risk of electric shock.
• Make sure you have good lighting and enough space to work behind the fridge.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.

Tools and materials needed

Before we dig into the repair process itself, let’s go over the tools and supplies you’ll need to successfully replace the main control board in a GE refrigerator.

Replacement Steps

Step 1: Access the Control Board

1. Pull the refrigerator away from the wall to access the back.
2. Locate the rear panel near the bottom—this covers the control board.
3. Use a 1/4-inch nut driver to remove the two bolts holding the panel in place.
4. Set the panel aside—you’ll now see the main control board.

Step 2: Document the Wiring

Before disconnecting anything:

• Take a picture of all the wiring harnesses connected to the control board.
• This will help you reconnect everything later without confusion.

Step 3: Disconnect the Wiring

1. Use your flat-blade screwdriver to release the ground wire from its connector.
2. Next, disconnect the two wiring harnesses at the bottom of the board.
3. Then, remove the four harnesses at the top.
4. Set the wires aside gently so they don’t get tangled.

Step 4: Remove the Old Control Board

1. Use needle-nose pliers to press in the plastic locking tab that holds the board in place.
2. Once released, carefully pull the control board out from its mounting position.

Step 5: Install the New Control Board

1. If your new board came with an updated ground strap, it should be connected directly to the metal cabinet of the fridge.
2. If your wire doesn’t reach the new location, you can flip or reroute the wiring harness so it does.
3. Position the left side of the new board into the mounting slot.
4. Tilt it back until the retaining tab clicks into place.
5. Reconnect the wiring harnesses using your earlier photo as a guide.

Step 6: Reassemble the Back Panel

1. Position the left mounting bolt to go through the back panel, the new ground strap, and into the cabinet frame.
2. Use your nut driver to thread and tighten it down.
3. Repeat with the right-side bolt, this one just goes through the panel into the cabinet.
4. Double-check that the ground strap is securely mounted under the left screw.

Step 7: Power On and Test

1. Plug the refrigerator back in or restore power at the breaker.
2. Listen for the fridge to start running and check the display panel or interior lights.
3. Allow a few hours for cooling to stabilize and check that the ice maker and temperatures are working properly.
