FAQ 

Q：Is fan failure always caused by the fan itself?
A: Not necessarily. Check the fan switch, fuses, and wiring connectors first. Inspect the fan motor for damage or blade seizure after confirming peripheral circuits are normal.

Q：Is 803502503 a cab fan or an AC fan?
A: The ZL50G/ZL50GL parts manual lists it as an “electric fan”. Some channels describe it as an AC fan or condenser fan (e.g., LW300F), which differs. Verify against actual equipment configuration to confirm the required fan type.

Q：What to note during electric fan installation?
A: Confirm the fan working voltage is 24V, matching the original electrical system. Orient the installation position reasonably to avoid affecting driver operation or obstructing visibility. Check wiring polarity and fix securely to prevent vibration loosening.

Q：How to maintain the electric fan daily?
A: Regularly clean fan blades and housing to prevent dust accumulation affecting air volume. Check terminals for looseness and blades for deformation, and address abnormal noise or speed promptly.
