CN303 of P.C. board correct?

YES

Correct connection of connector.

	Does the fan rotate without trouble						NO
	when handling the fan with hands under condition

	of removing CN300, CN301, CN302
	and CN303 from P.C. board?
			YES
	The status that the resistance values
	between leads below are 12 to 22Ω.						NO
	Between	1	(Red lead)	and	2	(White lead)

	Between	2	(White lead) and		3	(Black lead)
	Between	3	(Black lead) and		1	(Red lead) of
	motor winding of connector (CN301, CN303)
			YES
