How to Fix / Troubleshooting

Safety: Turn off power at the breaker and remove the lower front grille or rear access panel.

  • Inspect fan: Check for dust, debris, or packaging material blocking the condenser fan.
  • Spin test: Rotate the fan blades by hand. If they do not spin freely, replace the condenser fan motor.
  • Check wiring: Inspect the fan harness and connector for heat damage or looseness. Reseat the connector.
  • Voltage test: With power restored and cooling active, carefully measure voltage at the fan connector. If proper voltage is present and the fan does not run, replace the fan motor. If no voltage, suspect the main control board.
