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
Visually inspect the cooling fan for physical damage, obstructions, or debris that might prevent its rotation.
- 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
If the fan is physically damaged or non-functional, replace the cooling fan with an authorized spare part.
