Fan Failure

What does FAn1 mean?

The cooling fan, particularly in 8200 motec controllers (3...7.5 kW), has either failed or is disconnected. This condition can lead to the controller overheating, potentially causing thermal shutdown and reducing the lifespan of internal components if not addressed promptly.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify the integrity of the fan's wiring harness for any breaks or loose connections.
