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 there is
5k to 20kW resistance values between
1

motor position detection of
connector (CN300) is normal.

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.
