How to Fix / Troubleshooting

Safety first: Unplug the unit before removing the rear panel or handling the motor assembly.

  • 1. Inspect motor wiring:
    • Remove the rear panel.
    • Check the harness from the stator/hall sensor to the main PCB for damage or loose connectors.
  • 2. Check hall sensor:
    • Remove the rotor to access the hall sensor on the stator.
    • Inspect for cracks or physical damage.
    • Replace the LG hall sensor if suspect.
  • 3. Test stator:
    • Use a multimeter to check stator windings for continuity and shorts.
    • Replace the stator assembly if windings are open or shorted.
  • 4. Control board:
    • If motor components are good, the main PCB motor drive may be defective; professional replacement is recommended.
