If the LZ250 blower encounters a fault, you can troubleshoot it by following the steps below:

1. Unable to start: check the power connection, control system wiring and control panel status;
2. Unstable operation: check the integrity of the motor rotor, stator and fan blades, and correct the dynamic balance if necessary;
3. Abnormal noise: check the bearing wear or air duct blockage, if the bearing temperature is too high, the high-temperature solid coating protector can be replaced;
4. Insufficient wind power: check the balance of the blades and the smoothness of the air duct to avoid pressure loss caused by design defects.

For complex faults, it is recommended to contact the

manufacturer's technical support. Through regular maintenance and intelligent monitoring, the equipment can achieve 20,000 start-stop and trouble-free operation, with a service life of more than 20 years, significantly reducing the whole life cycle cost.
