   • Failure causes: blockage of air inlet or exhaust port, impeller imbalance, motor failure, etc.
   • Solution: Clean the air inlet and exhaust ports; perform dynamic balancing correction or replace the impeller; check the motor and repair or replace it.
4. Elevated temperatures:
   • Failure causes: insufficient lubricant, cooling system failure, overload operation, etc.
   • Solution: Check the lubricant and add the right amount; check the cooling system and fix it; avoid overloaded operation.
5. The motor will not start:
   • Failure causes: power supply failure, motor damage, starting device failure, etc.
