REFERENCE OEM PART NUMBER: AL1Z 19805 B, AL1Z 19805 A, CL1Z 19805 A
COMMON FAULTS AND ANALYSIS:
1.Blower fan does not move: The fan is used for a long time, which causes the friction coefficient between the rotor and the bearing to increase, and the rotor is blocked or even stuck, causing the coil to be overheated and damaged.
2.The fan does not turn, but there is a loud buzz: This fault is most common on capacitor-activated blowers, mainly due to lack of capacity or severe leakage of capacitors, or damage to the startup group.
