Gather the necessary tools

Fixing a refrigerator inverter board will require:

  • A quarter-inch nut driver – This will be used to remove and install the small mounting nuts that secure the inverter board. Select one with a comfortable grip and adequate length to reach the rear panel.
  • Phillips head screwdriver – A medium size #2 Phillips head will be ideal for removing and installing the screws on the terminal cover and ground wire.
  • Flat blade screwdriver – You’ll need this for prying off connectors and wire terminals during disassembly. Choose one with a sturdy, thick blade.

Step-by-step repair guide

Step 1: Accessing the inverter board

  • To begin, locate the refrigerator’s rear access panel. This panel is usually secured with multiple quarter-inch screws. 
  • Using your quarter-inch nut driver, remove these screws. 
  • As you work, keep track of each screw to ensure none are lost or misplaced. 
  • With the screws removed, carefully take off the rear access panel to expose the inverter board, typically found at the bottom near the compressor.

Step 2: Disconnecting the inverter board

With the inverter board now accessible, you’ll notice two harness wires connected to it. These wires are crucial for the board’s operation, transmitting power and signals to and from the board. 

  1. White plug: Locate the white plug connected to the inverter board. Press down on the tab and gently pull it apart to disconnect.
  2. Black plug: Similarly, for the black plug, press the tab at the back and carefully pull it out.
  3. Next, you’ll need to remove the cover box of the compressor terminals. This is typically secured by a single screw. 
  4. Use your Phillips screwdriver to remove this screw and then lift off the cover box. Be mindful of the components inside, as rough handling could damage the delicate terminals.

Step 3: Removing the old inverter board

With the electrical connections disconnected, proceed to remove the old inverter board. 

  1. First, you’ll need to remove a single quarter-inch screw that secures the board in place. This might be slightly inconvenient due to its position, but it’s manageable. 
  2. After removing the screw, gently tilt and slide the inverter board out from its mounting clip.
  3. Take this opportunity to inspect the area for any dust or debris that could affect the new board’s performance. Cleaning the area with a dry cloth can help ensure optimal operation.

Step 4: Installing the new inverter board

Before installing the new inverter board, compare it with the old one to confirm it’s the correct replacement. Then, follow these steps for installation:

  1. Position the new board: Carefully place the new inverter board in the same position as the old one. Ensure it’s properly aligned with the mounting clips and the screw holes.
  2. Connect the compressor plug: Attach the connector to the compressor. This plug has three holes that must match up with three prongs on the compressor. Align them carefully and push the plug into place.
  3. Secure the ground wire: The green ground wire needs to be connected to its terminal on the new board. Find the terminal marked for the ground wire and push the connector onto it.
  4. Mount the board: Insert the tab at the back of the inverter board into the slot on the refrigerator. Then, slide the side under the clip to secure the board in place.
  5. Screw the board in place: Use the quarter-inch nut driver to reinstall the screw that secures the inverter board.

Step 5: Reassembly and testing

After installing the new inverter board, it’s time to reconnect everything and test the refrigerator.

  1. Reinstall the compressor cover box: Place the cover box back over the compressor terminals and secure it with the previously removed screw using your Phillips screwdriver.
  2. Reconnect the harness wires: Attach the white and black plugs back into their respective connectors on the inverter board. Ensure they snap in place securely.
  3. Reattach the rear access panel: Align the rear access panel back onto the refrigerator, making sure all tubes and wires are not pinched. Using your quarter-inch nut driver, reinstall all the screws to secure the panel.
  4. Power up: Finally, plug the refrigerator back in or turn on the circuit breaker. Listen for the compressor to start up, indicating that the inverter board is functioning correctly. Allow some time for the refrigerator to cool down to verify the repair’s success.
