Remember, using the correct tools not only simplifies the task but also reduces the potential risk of damaging your appliance during the repair process.

Safety First

Safety should always be your priority when dealing with electrical appliances. Electricity can be dangerous if not handled correctly. Therefore, before you start any repair or replacement process, ensure your appliance is unplugged or the circuit breakers are switched off. This simple step reduces the risk of electrocution, making your DIY repair process safe and secure.

Understanding the Power Control Board

Before we delve into the repair process, it’s crucial to understand what a refrigerator control board is and its role in a refrigerator. The power control board, located at the back of the refrigerator behind a metal cover plate, is the brain of the appliance. It controls the compressor, fans, defrost system, and all other electrical components within the refrigerator.

When the power control board malfunctions, it can cause a range of issues, from temperature fluctuations to complete cooling failure. Therefore, if you notice any abnormal temperature behavior or your refrigerator isn’t cooling properly, it’s time to check and potentially replace the power control board.

Steps for Replacing the Power Control Board

Step 1: Removing the Back Panel

The first step in replacing the power control board is to remove the back panel of the refrigerator. This panel serves as a protective cover for the power control board and other electrical components.

To remove the back panel, you will need a quarter-inch nut driver. Locate the four-quarter-inch screws that secure the panel to the back of the refrigerator. Turn the screws counter-clockwise to loosen them, then remove them entirely. Keep the screws in a safe place, as you will need them to reattach the panel later.

Step 2: Removing the Plastic Cover

With the back panel removed, the next step is to take off the plastic cover protecting the power control board. This cover is typically secured by a locking tab, which can be opened with a flat-blade screwdriver.

Insert your screwdriver into the locking tab, gently pry open the tab, and carefully pull out the plastic cover. Be mindful not to break the latch, as it is essential for reattaching the cover.

Step 3: Removing the Old Power Control Board

Once the plastic cover is removed, you will have access to the power control board. The board is typically secured in place by a tab at the bottom.

To remove the power control board, press down on the tab with your flat-blade screwdriver while gently pulling out the control board. Be careful not to pull too hard, as you could damage the board’s wiring.

Next, disconnect the two plugs connected to the power control board. These plugs can be disconnected by pressing on the tabs and pulling them apart. With the plugs disconnected, you can completely remove the old power control board from the refrigerator.

Step 4: Comparing the Old and New Board

Before installing the new power control board, it’s a good idea to compare it with the old one. This comparison will ensure that the new part matches the old one in terms of size, shape, and plug locations. If you don’t have the new part yet, you can purchase it from AppliancePartsPros.com or any other reliable appliance parts retailer.

Step 5: Installing the New Power Control Board

Now, it’s time to install the new power control board. Start by putting the upper edge of the board into the saddle located at the top of the appliance. Then, align the pins on the board with the corresponding holes in the refrigerator.

Now, adjust the board so it fits snugly and securely. Press down on the board to lock it in place. Once the board is secured, reconnect the two plugs you disconnected earlier. Ensure each plug is aligned correctly before pressing it into place.

Step 6: Reinstalling the Plastic Cover

With the new power control board installed and the plugs reconnected, the next step is to reinstall the plastic cover. Align the tabs on the cover with the cutouts on the side of the refrigerator, then press the cover into place.

Make sure the cover is securely attached and that it completely covers the power control board. This cover is crucial as it shields the power control board from dust and damage, ensuring your refrigerator operates smoothly.

Step 7: Reinstalling the Metal Cover

The final step in the replacement process is to reinstall the metal cover. This cover provides an additional layer of protection for the power control board and other electrical components in the refrigerator.

To reinstall the metal cover, align it with the back of the refrigerator and secure it in place using the four-quarter-inch screws that you removed earlier. Using your quarter-inch nut driver, insert the screws into the appropriate holes and turn them clockwise to tighten them.

Ensure you don’t fully tighten the screws until all of them are in place. This will allow you to make any necessary adjustments to align the cover correctly. Once all screws are in place and the cover is properly aligned, you can fully tighten the screws.

Final Check

Now that you have successfully installed the new power control board, it’s time to perform a final check. Plug your refrigerator back in and switch on the circuit breaker. Allow the refrigerator to run for a few hours, then check to ensure it’s cooling properly.

If the temperature remains consistent and within the desired range, congratulations! You’ve successfully replaced the power control board in your refrigerator. If the temperature remains inconsistent, it could indicate an issue with another part of the refrigerator, and further troubleshooting may be necessary.
