What does 13 mean?
The power module heatsink temperature has fallen below –10°C. This indicates that the power module or its coolant agent is too cold, which can impact drive performance and potentially lead to condensation issues.
Common Causes
- Ambient temperature too low for equipment operation (P0310).
- Internal temperature sensor reading below threshold.
- Heating element malfunction if applicable.
Repair Steps & Checklist
