Precautions
* Some Fan Control PWBs are provided with a wire holder instead of the insulator lock. After repairing such a PWB,
remove the wire holder and bundle the wires with the insulator lock. If the insulator lock is cut off for repair purpose,
bundle the wires with a new insulator lock. (CE measures) Part code: LHLDW1033CEZZ
* If the output PWB has been replaced, readjustment is needed.
