Checking for Fan Motor
Remove fan motor connector and measure the resistance value between each of the pins (twice, one
measurementwith+/-leadsandtheotherwith-/+leads).Checkwhethertheresistancevalueisoveror
not according to the table shown below. When performing the second measuring, make sure to switch
leads(Red/Black).
