[P22 error]
Are connections of CN301 and
CN300 of P .C. board correct?
Does the fan rotate without trouble
when handling the fan with hands under condition
of removing CN301 and CN300 from P .C. board?
The status that the resistance values
between leads below are 50 to 80 W
for 40 W motor (ICF-140-40) and 25 to 55 W
for 60 W motor (ICF-140-60-1) is normal.

of motor position detection of
connector (CN300) is normal.
