Possible Causes

Seized outdoor fan motor, Obstruction in fan blades, Failed DC outdoor fan motor, Faulty outdoor PCB fan drive circuit

How to Fix / Troubleshooting

Safety first: Turn OFF the breaker. The outdoor fan can start unexpectedly; never work on it with power applied.

Steps:

  • Check for obstructions: Inspect the outdoor fan guard and blades for leaves, plastic, or ice buildup. Remove any obstruction carefully.
  • Spin test: With power OFF, try rotating the fan blade by hand. It should spin freely. If stiff or grinding, the motor bearings may be failing.
  • Inspect wiring: Remove the outdoor electrical cover and verify the fan motor connector is secure on the PCB. Look for burnt connectors or discoloration.
  • Clean area: Clear debris from around the outdoor unit to ensure proper airflow.
  • Test: Restore power and run the unit. If the fan still does not start and E7 returns, the motor or PCB is likely defective.

Warning: Replacing an outdoor DC fan motor involves working near high‑voltage components. If unsure, call a qualified technician.
