Possible Causes

Failed outdoor DC fan motor, Faulty fan motor driver on outdoor PCB, Loose fan motor connector, Incorrect phase sequence on three-phase power (for commercial units)

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker. For three-phase units, only qualified personnel should work on power connections.

Steps to check:

  • 1. Inspect fan motor connector: Open the outdoor unit and locate the fan motor connector on the PCB. Ensure it is fully seated and not burnt.
  • 2. Check fan blade: With power OFF, spin the fan blade by hand. It should rotate freely. Remove any debris or ice blocking movement.
  • 3. Observe startup: Restore power and briefly start the unit while watching the fan (keep clear). If the fan does not start or jerks then stops, turn power OFF again; the motor or driver is likely faulty.

When to call a technician: Replacing the outdoor DC fan motor or inverter PCB requires electrical skills. For three-phase units, a technician should also verify correct phase sequence and supply.
