Over-heat in Power Module Cooler

What does 3 mean?

This error indicates that the cooling system responsible for the power module has detected an over-temperature condition. This protective measure will typically lead to a thermal shutdown of the drive to prevent damage to the sensitive power components from excessive heat.

• Clogged or dirty heatsinks and/or cooling fans reducing cooling efficiency.
• Malfunctioning or failed cooling fan(s) for the power module.
• Ambient temperature around the drive exceeding its specified operational limits.
• Faulty temperature sensor providing an incorrect reading for the power module cooler.

Click steps to track your progress.

1. 1

   Clean any accumulated dust or debris from the heatsinks and cooling fans associated with the power module.

2. 2

   Verify that all cooling fans are operating correctly and providing adequate airflow to the heatsinks.

3. 3

   Check the ambient temperature within the drive cabinet; ensure it is within the specified operating range.

4. 4

   If accessible, measure the temperature of the power module cooler directly to confirm the accuracy of the sensor reading.
