Are connections of CN301, CN303
and CN300 of P.C. board correct?
Does the fan rotate without trouble
when handling the fan with hands under condition
of removing CN301, CN303 and
CN300, CN302 from P.C. board?
The status that the resistance values
between leads below are 25 to 55
for 63W motor (ICF-140-63-2) is normal.
Between (Red lead) and (White lead)
Between (White lead) and (Black lead)
Between (Black lead) and (Red lead) of
motor winding of connector (CN301, CN303)
The status that there is
5k to 20k resistance values between
(Yellow lead) and (Pink lead)
of motor position detection of
connector (CN300, CN302) is normal.
Normal fan motor
(CDB P.C. board)
Defective fan motor
NOTE :
However, GND circuit error inside of the motor is rarely detected even if the above check is carried out.
When the circuit does not become normal even if P.C. board has been replaced, replace outdoor fan motor.
