of removing CN301 and CN300 from P.C. board?
	YES
The status that the resistance values
between leads below are 50 to 80W
for 40Wmotor (ICF-140-40) and 25 to 55W			NO
for 60Wmotor (ICF-140-60-1) is normal.
Between	1 (Red lead) and	2 (White lead)

Between	3 (Black lead) and	1 (Red lead)
of motor winding of connector (CN301)
	YES
	The status that there is
5k to 20kΩ resistance values between			NO

Normal fan motor

(Control or CDB P.C. board)

(Control P.C. board or CDB P.C. board)

NOTE :

Defective fan motor

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.
