Repairing procedure

Tools Needed:

  • Multimeter (for testing thermistors and electrical connections)
  • Replacement parts (control board, thermistors, cold fan motor)

Safety Precautions:

  • Unplug the refrigerator or disconnect power at the circuit breaker.
  • Wear safety gloves to protect your hands from sharp components.
  • Ensure the area is well-lit and dry.

Replacing the Control Board:

  • Access the Control Board: The control board is typically located behind a panel at the top or back of the refrigerator. Use a screwdriver to remove the panel.
  • Disconnect the Old Board: Carefully disconnect all wires connected to the control board. It’s helpful to take a picture before disconnecting to ensure proper reconnection.
  • Remove the Old Board: Unscrew any fasteners holding the board in place and remove it.
  • Install the New Board: Mount the new control board in place and secure it with screws.
  • Reconnect Wires: Refer to your photo or diagram and reconnect all wires to the new board.
  • Reassemble: Replace the panel that covers the control board.

Replacing Thermistors:

  • Locate Thermistors: Thermistors are usually found in the refrigerator and freezer compartments, attached to the back wall or near the evaporator coil.
  • Access and Remove: Depending on their location, you may need to remove shelving or panels. Disconnect the thermistor(s) from the wiring harness.
  • Replace Thermistors: Connect the new thermistor(s) to the wiring harness and secure them in the same location as the old ones.
  • Reassemble: Reinstall any components or shelving you removed to access the thermistors.

Replacing the Cold Fan Motor:

  • Access the Fan Motor: The cold fan motor is typically located near the evaporator coil in the freezer compartment. You may need to remove drawers, shelves, or panels to access it.
  • Remove the Old Motor: Disconnect the fan motor from its electrical connector. Remove any screws or brackets holding the motor in place.
  • Install the New Motor: Mount the new motor and secure it with screws or brackets. Reconnect the electrical connector.
  • Reassemble: Replace any components, drawers, or shelves you removed.

Final Steps:

  • Power On: Once all parts are replaced, plug in the refrigerator or turn on the power at the circuit breaker.
  • Check Operation: Allow the refrigerator to cool for several hours. Verify that the temperature settings are correct and that the unit is cooling properly.
  • Monitor: Keep an eye on the refrigerator’s performance over the next few days to ensure everything is working as expected.

Tips:

  • Refer to the Manual: Always consult the refrigerator’s manual for specific instructions related to parts replacement and diagrams.
  • Label Wires: When disconnecting wires, label them or take detailed photos to ensure correct reconnection.
  • Be Methodical: Keep track of screws and components as you remove them to ensure a smooth reassembly process.
