What does Fan Failure mean?

This indication appears when the inverter's internal cooling fan stops operating due to a fault or operates in a manner inconsistent with the setting of Pr. 244 'cooling fan operation selection'. A faulty cooling fan can lead to inverter overheating and subsequent shutdowns.

Common Causes

  • Mechanical failure or physical damage to the cooling fan.
  • Blockage preventing the cooling fan from rotating freely.
  • Incorrect setting of Pr. 244 'cooling fan operation selection', leading to unexpected fan behavior.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Visually inspect the cooling fan for physical damage, obstructions, or debris that might prevent its rotation.

  2. 2

    Verify the setting of Pr. 244 (cooling fan operation selection) to ensure it aligns with the expected fan operation (e.g., continuous, stop/start).

  3. 3

    If the fan is physically damaged or non-functional, replace the cooling fan with an authorized spare part.
